Long-awaited China medical reform introduced in the new programme will

"Saviors" new health reform programme is expected to be announced in January 2009.

Including medical insurance, essential drugs, primary medical care system, public service equalization, public hospitals, five of the reform of the supporting programme will also be at the "debut".

The Communist Party Secretary of the Ministry of health, Ministry of health before high-strength development of concrete, clear, with operations of the three-year programme recently implemented with new health reform programme together.

Called "new health reform programme" of the deepening of the medical and health system reform Act (draft) published on October 14, only a month to receive comments and suggestions are more than thousand articles.

This programme can resolve "the difficulty and high cost of" a social focus.

Health reform coordination group experts revealed: the revised new health reform programme has not changed the basic guiding principles, a clear government financial investment in health in focus areas are public health, rural health and rural health development; while the specific content of the adjustment is not great; including essential medicines and hospital reform is key.

The new programme will publish national essential medicines list, determine the varieties and quantities, the establishment of the production system, unified price, bidding fixed-point production or centralized purchasing, direct distribution, proportionate provisions of hospitals.

Public hospital reform of the guiding principles are "separating, MO apart."

In the comments, some parts of the pilot study has quietly, Guangdong, Shenzhen, Shaoguan and Zhanjiang start canceling public hospitals through the addition of 15 per cent.

Started in 1978 health reform, China experienced health insurance reform, implementation of the reform of the "property" and reflection and reconstruction phases.

In the meantime, the Ministry of health has proposed that the Government only some public hospitals and other medical institutions of market reform. However in 2003 "SARS" crisis of the bitter lessons and 2004 published by the national health service survey report confirms that people "expensive, difficult," and other practical contradictions, changed the guiding idea of health reform.

In May 2005, the Ministry of health, stated: "the market of non-medical reform direction" medical reform aims to construct a benefit "national" medical security platform.

Since then, the national launch in town resident medical insurance, and the decision in February this year, the pilot cities from last year, 88 expanded to more than half of the country, the city is the "block" in the medical insurance network in the town of non-residents and the urban employees enjoy medical insurance.

At the same time, in the establishment of rural universal new CMS, currently covering a metres, of more than seven million County farmers a doctor can be reimbursed, the country has had nine million passengers enjoy medical compensation amounting to $ 91 billion yuan.

Next year the new CMS will achieve comprehensive coverage and financing standards from $ 50 per person per year to 100 RMB, in which the Government grants standard raise to $ 80 by $ 40.

Some experts claim that China's basic medical insurance, basic medical insurance in town resident and new CMS has been realized on the full coverage and rural residents, the formation of the basic medical insurance system, but the national framework are still fails the second servicers, not to any medical care.

In addition, to improve health care resource layout, narrowing the gap between medical facilities, enhance the technical level of the medical quality supervision are still faces many problems and difficulties, "the new health reform programme" to go forward.

Medical electronic eye: Biosensor research priorities (1)

First, the origin of biological sensors

The 60 's of the 20th century, Updike and Hicks to glucose oxidase (GOD) immobilized membranes and oxygen electrode assembly, first made the first bio-sensors, i.e. glucose enzyme electrode.

To the 80 's biosensor research area has been formed. Its flagship event is: in 1985, the International Journal of bio-sensors "magazine in the United Kingdom; 1987 biosensor classics at Oxford publishing; in 1990, the first World Congress on biosensors to convene, and Singapore. Bio-sensor is a very active area of research and engineering, it and bioinformatics, biochips, biological Cybernetics, bionics and bio-computer sciences, Department of life science and information science in interdisciplinary areas. Their common characteristic is: explore and reveal the life system information of production, storage, transmission, processing, conversion and control, the basic rule on applied to basic human economic activities. Biosensor technology research focuses: widely used various bioactive materials combined with sensors, research and development have the recognition of the transducer, and manufacture of new types of analytical instruments and analytical methods of original technology, research and development of their application. Biosensor applications of bioactive material objects include biological molecules, cells, organelles, tissue, organ, etc, as well as synthetic molecularly imprinted polymers (molecularlyim2priniedpolymer, MIP). Due to the study of DNA or protein molecular recognition technology has developed biochip (DNA Microarrays, protein chip) independent subject areas.

Test substances by diffusion effect into bioactive materials, molecular recognition, the biological response, produce information then is the appropriate physical or chemical transducer into quantifiable and can handle the signal, then the secondary instrument amplification and output, we can know be measured concentration.

Preview the RSNA 2009 Chicago

Medical device manufacturers around the world are dedicated to this year's radiology event for final preparations: will be held in Chicago in 2009 of the Radiological Society of North America (RSNA) Annual Conference.

This exhibition will be opened on 29 November, continuing to 4 December, active content such as lectures, exhibitions, have the opportunity to meet peers and preview the latest achievements of medical device innovation, attracting people from all over the world attended.

A year of hard hit by the financial crisis, companies want to be able to take advantage of this opportunity to find the procurement of equipment for a large investment.

The past year and a day of medical device manufacturers are very sorry for product display manufacturer.

The economic downturn and the resulting credit crunch, in the second half of 2008 resulted in cancellation and delayed orders increase, and in 2009 the limits of new opportunities.

Manufacturers in the second half of this year has seen some signs of improvement in the situation, but at the cost of product discounts and innovative financing terms. United States Congress on Medicare reform debate, also increases the complexity of the situation. Health service providers, various unpredictable may reform proposals on the future of the budget and equipment needs and the impact.

For image archiving and communication system (PACS), high-performance diagnostic monitor, represents today's liquid crystal display (LCD) market every inch operating income up market opportunities.

Initially used to display a previously recorded in black and white film above image, grayscale monitor has long ruled the market. But gray continuous improvement of high luminance color display, gradually in grayscale monitor to gain a foothold in the ocean, and is currently medical monitor industry's hottest growth opportunities. Different than in recent years has entered a negative growth of grayscale monitors, in recent years to have diagnostic quality color monitor demand continues to increase, as customers color display provides flexibility, demand is expected to increase in 2010.

Figure 4 shows the iSuppli Corporation on color and black and white PACS shipment forecasts.

While many of the radiological imaging are single-gray, but the color plays a more important role, especially in the three-dimensional images in different colors can depict complex veins, arteries and organs, nerves and bones network roadmap.

Computer tomography (CT), magnetic resonance imaging (MRI), ultrasound and Positron Emission Tomography (PET) imaging of color, to generate comprehensive diagnostic images provide increasingly important data.

However, the gray-scale monitor, especially for breast x-ray photography of 500 megapixel and high-megapixel model, not disappear in the near future.

Most health centres are on the increase in the new color table, or change the gray-scale monitor out, in exchange for color display, instead of replace all grayscale display. In this year's exhibition, in addition to a variety of high performance color monitor, the participants will be able to see many new grayscale display.

In fact, the most affected by 2009 exhibition is a grayscale monitor look forward to, specifically, is the use of Chi Mei's 30-inch 1000 megapixel grayscale Panel of the monitor.

Radiologists have long complained about the "slot", i.e. 500 mega pixel dual monitor in the middle of the slot. Chi Mei's 1000 megapixels Panel provides no slot solution so that users can be in a single glass panel above observation of emission of two side by side 500 mega pixel image.

Some vendors in 2008 RSNA exhibition shows a panel sample, but the Panel is still under development, there are some obvious flaws.

The industry says that these defects have already been resolved, 1000 megapixels solutions ready for Grand debut. Expected to be in the majority of monitors booth to see the adoption of the Panel of the monitor, but due to the limited number of exhibits and want to see a lot of people might, therefore, prepared to wait in line, if you have the chance to you can give it a try.

But you must not miss this opportunity, packed backpack, prepare by 2009 RSNA exhibition about future trends.

China's IT industry in the last piece of the "fat" — medical information

It has been said that the medical industry IT is China's IT industry in the last piece of the ' fat ', indeed, it looks great, but it does not ' fat '.

Foreign manufacturers of the "cake" mainly in hardware procurement, domestic mainly doing software.

Because the price is too high, but localization is difficult to solve, so the software part is still controlled by the domestic enterprises, but it also does not benefit than do hardware, "due to domestic enterprises are mainly concentrated in the software field, so the market has been divided up very carefully. ”

Domestic medical information can be divided into three phases: the first stage is HIS, but mainly to finance information system, at present, 70 percent to 80 percent of the hospital still at this stage; the second stage is the hospital system, will join some clinical something, such as electronic medical records, health check-up, and now there are 20 percent of the country's health care is changing to the stage; in the third stage is the public health area information, including a number of system shared between hospitals, as well as small and medium-sized cities or major cities an interregional sharing may involve residents archives, health emergencies, and so on.

While this phase in the next two to three years should become a trend.

In General, large hospitals are actively promoting clinical IT applications, such as doctors, nurses workstation, the workstation with foreign advanced level very close.

Currently, although there is no industry-wide data IT needs, but estimates IT annual budget revenue share percentage overall hospital about 0.5%-1%, is significantly low levels.

It is understood that the present Beijing Xiehe hospital, 301 hospital and other hospitals have separately in 60 rooms, six of Ward has established a mobile clinical workstation, Shanghai changning maternal and child health hospital is in 7 layers Ward floor adoption 32 wireless access point, AP, doctors and nurses can at any time before the beds for vital signs data, health data and inputs, doctor wards, bedside care, call communications, care monitoring, drug delivery applications.

But due to the personnel training for the lag, HIS application was not optimistic.

Despite HIS financial system embodies its superiority, but otherwise still does not reflect the convenient. Health care workers are usually will understand the situation in the present, and then type into the computer, due to computer operation of unskilled, make a doctor's clearance imperceptibly become excessively bureaucratic.

You can see, the potential demand, after all, just a kind of intention for IT companies to truly translating it into their own markets, but also a very difficult process of climbing, the most difficult period should be the realization of information sharing.

Information sharing is a fundamental point of electronic medical records, if possible, not only is an important basis for the diagnosis and treatment, are also important medical research practice data sources.

However, in practice, electronic medical records but encountered many challenges.

In Singapore, the country's only two large medical group-national health insurance group health insurance group and Singapore, each group of controlled many hospitals and clinics, but each group is only one part of comprehensive it information, therefore, in the same interest of the community for information sharing is easy.

On the other hand, the Chinese market, but opposite, 18 million hospital located in the small city, between the hospital and the hospital is different interests, the information is very difficult to share.

In fact, electronic medical records in the information-sharing challenges is only an apparent deeper problems in the internal organisation and hospital management, business process changes.

"Once the information system, hospitals, traditional management structure, the traditional management processes and organization are great changes. And this is present in many hospitals unbearable or reluctant to accept. "One of the medical professions in the industry.

Medical Imaging by leaps and bounds, perspective amazing human body structure (1)

According to the United States in the exploration of the magazine reports, medical imaging technology in the past few years a rapid development, and now, these new technologies can identify any structure and human body many important biological processes, such as different flow velocity.

Following this set of pictures not only reveals the structure of the human body after illness, but also visually to shock.

1. diffusion tensor Imaging

Schizophrenia brain diffusion tensor Imaging (DTI)

A description of a new method of brain structure is called diffusion tensor Imaging (DTI).

This picture is the medical staff in the study of patients with schizophrenia, the use of diffusion tensor imaging technology production.

Such as this graph of diffusion tensor Imaging (rendering and previous image) can reveal how the brain, nerve cell connections influence medical staff guidance for brain surgery.

Unveiling the next medical technology: wandering in the blood of micro robot

Since the application started bloodletting, healthcare technology has come a long way.

The future of healthcare technology and even will make today's most widely used therapy has become obsolete. A similar capture cancer of nanoparticles and virus of lasers and light heart monitors, medical technology breakthrough makes targeting technology has begun to enter the new era. Take advantage of targeted therapy techniques, drugs will be directly guided most part needed, treatment is a healthy body tissues also will no longer be involved, the disease has just been signs of a wire can also be detected in real-time.

Call tone to physical examination of lasers

From 1954, alcohol measuring instrument has been used to determine whether alcohol or drunk drivers.

United States Colorado University physicist suiye military apply this concept to a whole new areas: medical diagnosis. As long as breath a sigh of relief, he designed the device can detect thousands of different biological molecules, but also sensitive enough to pick up perhaps represents the specific disease of rare biological molecules. On the outbound content from a snapshot, you can check out from cancer to cystic fibrosis, and many other diseases.

This instantaneous diagnosis by a field called "optical frequency comb" laser-driven, can issue a broadband optical waveguides and air compounds react.

Optical frequency comb is used to measure the different color (or frequencies) of light, its comb line is adjusted to specific elements of a clear frequency or optical activity. While the entire optical frequency comb can cover a wide range of spectral range, its a lot like a rainbow of color, to monitor the thousands of different molecules. Suiye military said, when in regular intervals optical frequency comb icon, you see the "Rainbow", once breath molecules pass through the "Rainbow", the set of resonance frequency makes the optical frequency comb looks like a missing tooth. When many respiratory molecules are also monitored by then, so you can be provided with specific diseases of high reliable information. For example, the last of the illustration shows the presence of carbon monoxide, hydrogen peroxide and nitric oxide, breath could suffer from asthma.

Suiye military said, patients do not have to spend a few days to wait for the test results, "just a minute, you'll know what's going on".

Pre-emptive early tumor surgery

The world's scientists are committed to the development of new cancer treatment method, these new methods including more effective chemotherapy and better bone marrow transplant program, and the United States John Hopkins University chemists Thomas • Ken Kessler is committed to using the more advanced and effective new treatments to replace all of these efforts.

Ken Kessler and Dartmouth College of colleagues together to reveal a way to prevent cancer-early formation in amazing ways.

Just like earthquakes and avalanche, cancer is the entire sequence of instability caused by the results, such as abnormal cells in the wrong time in wrong place; cellular and intercellular communication were broken; cell blindly for proliferation and differentiation. Ken Kessler through use of a known as CD Juan DO — Im of oleanolic acid analogues compounds for the treatment of health organizations, in the laboratory to disturb the sequence. From plant acid CDDO — Im activates the toxic compounds from cells — compounds (may cause cancer by making a DNA mutation) Elimination of natural enzymes. CDDO — Im also has other oleanolic acid derivatives as anti-inflammatory activity. All of these makes CDDO — Im with cancer prevention role. CDDO — Im prevention of aflatoxin-induced cancer than so far known other cancer prevention agents are more effective.

Ken Kessler said that the next few years, Im still CDDO — cannot be applied to the clinic.

But you can give patients a day, a healthy person can choose according to their own genetic susceptibility and environmental conditions of use of this approach. Researchers aim is to prevent very early cancer occurrence of significant change.

Real-time monitoring of blood pressure of implantable Nanowires

In the doctor's Office to conduct routine blood pressure checks, maybe will soon become a thing of the past.

United States Georgia Institute physicist wangzhonglin has devised an implantable of nanowires, can continuously measuring blood pressure fluctuation, the patient at home will be able to track their own physical condition.

The sensor works? researchers use of Nanowires has two important properties: it is both a semiconductor, but is a piezoelectric material.

This means that, if the imposition of an external mechanical force the Nanowire, such as vasoconstriction of external forces, nanowires will produce a line of electric field. This field presence affect the nanowires conductivity, which can be measured. If the conductivity changes, also indicates that blood pressure is changing.

This technology more than ever, technology has improved significantly.

Legacy device in arm needs a considerable wrapped in cloth, but the new sensor can be implanted in his arm and real-time monitoring. Patients wearing a watch-like device to record data, once an exception occurs, the watch will be able immediately to patients or doctors send alarm signal.

This implant-Nanowires may also have other potential applications.

Scientists often need to automatically measure very small pressure variables. For example, in hundreds of kilometres of natural gas pipelines, similar sensors can help predict potential explosion risk.

Against superbugs-infrared laser

Antivirals and antibiotics have been HIV and Staphylococcus aureus that root bacteria from the first line of Defense, but anti-virals and antibiotics are also a number of serious drawbacks: antiviral medicines can wreak havoc in the pancreas and liver, and antibiotics are on fixed-resistant strains has no effect.

In response, the United States, Arizona State University physicist Professor KT • has developed a multi-function treatment tools: one can kill bacteria and viruses without harming the surrounding tissue of infrared laser.

This method of innovation is to laser to destroy the mechanical way, instead of the pathogen to chemical or biological means.

Researchers use lasers in fineBacteria or virus protein shell manufacturing a large vibration, activate it to a sufficiently high energy State, leading to weak ties with the shell. Because of the mammalian cell does not have such a case, this method will be able to keep the patients body intact of the destruction of those unwanted germs.

Professor said that preliminary results of in vitro tests indicate that the laser effectively destroyed the AIDS virus.

Based on the progress made so far, researchers in the two years the hospital used such laser is optimistic.

No side-effects of microbubbles targeted drug delivery

Drugs can follow the design uses to treat disease, however, when the drugs are indiscriminate be absorbed into the blood vessels can also be triggered the debilitating side effects.

For example, chemotherapy nausea and tablets can be raised in alopecia, and antibiotics can cause fatigue and shortness of breath.

In order to help patients overcome side effects, Philips's pharmaceutical sector is developing a similar to target missile delivery systems.

Philips scientists will put drug particles of fluorocarbon gas micro-bubble, and then injected into the patient's blood. When the bubbles reach the treatment target area, the technical staff of a high power ultrasonic pulse, and led to the formation of bubbles bubbles burst, the resonance-release drug particles.

The project's lead scientist kelisiduofu • Hall said that the micro-bubble will take a more rational way to pay the amount of chemicals, high concentration of the correct drug to need treatment.

One day will be able to use the bubble wrapped drugs to treat prostate cancer, breast cancer and fights, and eliminates the often treat these diseases must pay the price of intense body.

Wandering in the blood of micro robot

At present, like a tumor resection or unblock blocked arteries, and so on operation requires a presence in the hospital patients with a very long time.

But Israel Technology Institute of engineers Vaux Dade • Solomon developed a mosquito size robot will enable doctors to the purposes of these operations do not need to leave a large incision, therefore can make patients recover more quickly.

Creativity derived from the last century 80 's game with the laser surgery: micro-task of a clue, Solomon made robot is only 1 mm in diameter.

This is called "the robot, ViRob" it'd hooked metal arm to grasp the venous and arterial, and take advantage of built-in cutter cut a little organizations. In most normal operation, the probe for manipulation, doctors must take an out of the body of an external handle, but there is no "ViRob" such restrictions. Robot once injected into the vein, the operator can place the external magnetic field tuned to different frequencies to manipulate its speed and direction.

Solomon said, because you don't have to physically external manual control "Rob" Vi Juan, so doctors can access another surgery cannot reach the area.

Doctors can even to a patient at home for remote operation. He predicted that the professionals will be in 5 years using the robot to biopsy and procedures such as vascular repair.

Posted in heart of wireless ECG

The morning after, as long as they could wake up to the chest with a super light patch, we will be able to ensure the computer all day time monitoring your heart beat.

This is the Netherlands Horst Center image incentive experts developed the next generation of ECG monitor, in size and simplicity are than similar products.

Research Program Manager Julian • Pan Desmond said, use the normal electrocardiogram monitor must be an electrode Plug and test to pocket a fixed box connected the new appliance is a significant step forward, to the entire body surface wear.

Hidden in the secret behind the ultra-small detector is a chip, the chip can be monitored from patch-electrode signal and transmit wirelessly to a computer to read the signals.

This type of intelligent chips with low power for optimal performance, without the need for bulky battery compartment, so as to apply to preventive medicine.

Mr Desmond said, a less invasive techniques. This flexible wireless device just simply attached to the user can at any time in the chest, his heart rate monitoring.

Science fiction come true Nano Cancer Fighter

The 1960s, one called the "singular" science fiction film journey, the story is a Soviet scientists fled to the United States, because he was a spy of cerebrovascular damage in the face.

5 United States doctors be reduced into a fainter, injection into scientists to vascular surgery in the body. United States MIT engineer sangue Tower • batia will this science fiction becomes reality, she developed programming can get straight into nanoparticles for cancer cells, and to the nearby release chemotherapy drugs.

Batia doctorate at the Massachusetts Institute of technology, specializing in how micro-manufacturing process for human tissue engineering to restore liver function, and micro-fabrication technology was originally used in the manufacture of semiconductor chips.

Later, batia sidetracked, want to use a variety of approaches to development had been used for coating and computer technology used to manufacture small body parts. Thus, this miniature cancer killer — Nano-particle was born.

The particle surface is a substance, to the cancer cells to "home", one of the categories of substances containing peptides, peptides can be used with the tumor blood vessels, protein binding, so they become toxic chemotherapy directly into the tumor cells "striker" toxic drugs travels in systemic side effects.

Batia, the nanoparticles to get the United States food and Drug Administration's approval to enter the clinical application, 5 to 10 years.

At the same time, researchers are developing a way to track tumor is doing and what's new material to learn about the tumor is more intrusive or staging, so that the proliferation of cancer can be treated with before.

Biodegradable scaffold of stem cells

Injured location for emergency repair of the lost tissue, stem cells need a stent to growth, but like plastic such artificial material cannot become such branch

Frame, because the body will put this class of artificial materials marked as foreign substances and rejected.

Ravi • Kane is the United States, New York, Rensselaer Polytechnic Institute of biology of the engineer, he used the Brown algae in a complex natural carbohydrates alginate, produce biodegradable scaffold of stem cells, and thus avoid the above problems.

Embed in brackets is called micro-bubble of release over time, as well as micro beads are called alginate lyase of carbon in vivo, the last embedded scaffolds in adjustable rate degradation.

Kane hope this algae bracket enables doctors to stem cells implantation of directly injured tissue, such as the healthy bone stem cells implantation of the fracture site, or the neural stem cells implantation in the Alzheimer brain lesion area.

The future of the series is "two in one" package, you can simultaneously transmit stem cells and drug molecules. Kane said, this is a modular system, still have space on the bracket, you can also apply other types of particles placed in it.

Deep brain internal magnetic pulse

20% of depressive patients on treatment of drug fluoxetine (Prozac) is not responding, the traditional final treatment means will have to use electric shock therapy.

Recently, researchers around the world are beginning to delve into a promising new therapy: Transcranial Magnetic Stimulation (TMS). Use of TMS, attached to the scalp of metal coil produces magnetic pulses in the brain produces a small current to stimulate the brain and depression-related area of nerve cells without damaging surrounding gray matter.

This spring, this treatment method adds more power, because Israel Brainsway company announced that they have successfully tested the technology of the latest, the depth of the TMS.

The company's CEO, Phil Woods • cable, standard TMS device for magnetic field can only be extended to the cerebral cortex of about half an inch (about 1.3 cm). But the depth of the TMS in magnetic field coil can be projected onto the skulls of some points around, can stimulate a deeper neurons. This means that, for the first time, the clinician can be emotional debugging on play an important role in brain positioned deep limbic system-directed therapy. To date, the unit has achieved very good results, in 64 accepting depth TMS therapy, 40% achieved distinct clinical rehabilitation.

The company is lobbying for the United States food and Drug Administration approved the use of this device, Phil also is evaluating depth TMS on Parkinson's and influence of the cerebral cortex of the darker the applicability of other neurological diseases.

Keeping the heart device cost, power and functionality of the balance between

Current cardiovascular disease has become the world's leading causes of death.

It is estimated that in 2005, about 1750 million people died from cardiovascular disease, which accounts for the global death toll of around 30%. But in these deaths, 760 000 people died of a heart attack is 570 million people die from stroke. As of 2015, estimated to be 20 million people died from cardiovascular disease, heart attack and stroke is the result of such major cause of death. And a large number of deaths may have any cardiovascular disease symptom will occur.

Electrocardiogram (ECG) monitor is health care providers use of important tools used to help identify heart problems, and monitor patients ' health.

ECG heart cells generated by measuring the pressure to monitor the heart. ECG vector in the sinus (SA) to generate the right atrium and then as a vector to the entire myocardium. Represents time in x axis and representative graphic dot of the Y axis shows the measured results, its signal is shown in Figure 1.

Figure 1 contains a datum point and the measuring of the ECG signal

ECG monitor comes in many forms, including those involving remote monitoring of handheld devices and hospital use integrated patient monitoring system.

Since the early 20th century Willem Einthoven established the first practical ECG, all ECG equipment's basic design is established, only the waveform and application is different.

If you want to get the ECG signal, must be in a different location for scheduled patients use skin sensors.

When the heart is complete normal cardiac cycle, the sensor surface record electronic activities will change. As a result of a healthy person's heartbeat, including cardiac depolarization and recovery polarization etc series standard activities, their strong graphics displayed ECG cyclical. However, abnormal heartbeat (e.g. heart flutter) or arrhythmia patients you may generate non-cyclical ECG graph. In other words, abnormal heartbeat displayed ECG graph and normal people, but it still might have cyclical. Examples of such exceptions include the heart rate is too slow or too fast, in which case each heartbeat still and another time the heartbeat is similar, but different than the healthy heart frequency.

Latest ECG equipment design in appearance and functionality implemented innovation.

Old ECG devices will print the ECG for clinical analysis, but a lot of new ECG version you do not need to be patient here, by advanced algorithms for monitoring and diagnosis of patients. Although in many cases the clinical assessment of ECG graph remains extremely important, but now the process is automated, so it can be more time for more patients are monitored. This automation lead to cardiac function in monitor. This type of monitors does not require a continuous watch on the wards, but once you have depending on the detected arrhythmia it will immediately alert you to the clinician.

ECG evaluation of automation, medical equipment designers bringing new opportunities and challenges.

These instruments were developed for a large number of applications, such as the need for continuous understanding of high risk populations, as well as indoor monitor doctors for anesthesia is used to track the status of the heart function integrated devices. In order to continue to produce health effects more but smaller devices, there are some common issues to be resolved.

The core of these problems in ECG signal is analysis and detection algorithm efficiency.

In the past, arrhythmia by highly trained doctors for the diagnosis. From the doctor converted to electronic equipment diagnosis is a daunting task, to be improved. However, the development of new algorithms to improve diagnostic accuracy can save considerable costs. Nursing care of patients affected by and they each episode, the device can accurately diagnose to arrhythmia has a close relationship. Algorithm to perform these tasks by effect appears when the better, it's role in clinical settings. However, to improve accuracy typically require more code and more complex programming, which in turn require running code devices have more onboard memory, causing increased production costs.

An ideal method is to use mathematical precision, to reduce code size, memory requirements, and the final cost, but at the same time continue to achieve precise diagnosis of the current industry standard.

Recently, Monebo software has developed this algorithm. Unlike most commercial algorithm, ECG Intervals of Kinetic Monebo algorithm does not require patient ECG graphics sample warm-up phase, this phase will usually be ignored. Preheating sampling is a commonly used practice operation because it ensures that devices read the "real" ECG graph instead of device startup due to transient phenomena and distortion of the image. Preheating sampling can minimize some wrong diagnosis at the probability of occurrence. However, this approach will need to add additional code to determine the actual testing begins, by the way, as well as where to save the data you want to discard. On the other hand, the use of advanced signal Monebo solutions are technology and key "Datum" point-sampling, cancelled the warm-up time, Monebo algorithm has a leaner code requirements.

Efficient ECG testing code, for equipment designers is a godsend.

It allows designers to focus on the specific implementation, and ensure that within their arrhythmia detection algorithm to work correctly, and does not consume additional memory. As previously mentioned, all cardiac monitoring equipment was created are not the same. For example, many lead wireless indoor ECG monitor requires battery cycle length, production costs low, while more complex hospital-grade equipment may need more processing power level and the real-time operating system (RTOS) to run additional applications. Many manufacturers production covers the entire range of equipment. Therefore, the algorithm can and ECG series of processing kernel easily connect is crucial. These kernel in the power and functionality to meet the requirements of the device.

Monebo cooperation with Freescale Semiconductor has been solved

Hardware platform flexibility. Monebo 500 using Freescale microcontroller (MCU), processors and digital signal controller (DSC) advantage, will their Kinetic Intervals algorithm widely used in numerous applications. In particular, the Freescale Flexis QE pin and soft foot-compatible 8-bit and 32-bit MCU series, was used to provide ultra-low power consumption for longer battery life. Low power operation is a next-generation wireless and handheld device will consider health care.

Since the Einthoven development since the string galvanometer, ECG technology has come a long way.

Automation of the latest innovations will enable more people from arrhythmia benefit of diagnosis. Although this area has already made significant progress, but the next generation of cardiac monitor developers still have to pay close attention to the diagnostic accuracy, code complexity, economy, efficiency and power consumption of the device. Monebo and Freescale hardware portfolio platform not only addresses the current challenges faced by them, and provide the ability to meet in the next few years ECG device developers to technical requirements of collaboration solutions.

Latest digital hearing aids design challenges and related considerations

The latest hearing aids are digitally programmable, which means that although they have an analog signal processing functions, but by audiologists may adjust the number of parameters to control processing.

Digital hearing aids in the design, engineer will encounter which challenge? how to deal with them? this article will provide you an interpretation. Design challenges hearing aids designers have strict technical requirements. Hearing aids must be small enough to place the human ear or ears, ultra-low power must run, and no noise or distortion. To meet these requirements, existing hearing aid device consumes power to less than 1mA, operating voltage to 1V, utilization of chip area less than 10mm2, this usually means that two or three devices are stacked. A typical analog hearing aids with non-linear input/output functions and frequency dependent gain amplifier. But this simulation processing relies on custom circuit, compared with digital processing, lack of programmability and more costly. The latest digital equipment with its corresponding simulation equipment, reducing equipment cost, reduced power consumption. Digital equipment's biggest advantage is its improved processing power and programmability, allows custom hearing aids to apply to a specific hearing impairment and the environment. Replace it with a simple voice amplification and adjustable frequency compensation for more complex processing strategies to improve provided to damage the ear sound quality. But such policies require DSP can offer extremely complex processing functions. In General, there are two types of hearing loss: conductive hearing loss and sensorineural hearing loss (SNHL). When the patient's ear or middle ear sound conduction anomalies will occur conductive hearing loss, and when the cochlear auditory sensory cells or higher in the problem of neural mechanisms of sensorineural hearing loss can occur. If a conductive hearing loss, you cannot normally through the middle ear or tympanic transfer sound. Because voice is mainly composed of conductive losses decay, so you only need to enlarge the sound can be recovered nearly normal hearing. Does not need any special signal processing, traditional analog hearing aids to good work. However, only 5% suffered from some hearing loss are attributable to the conductive losses. Another type of hearing loss is SNHL. It includes and old age-related hearing loss, and noise-induced hearing loss and taking up on auditory system harmful drugs cause of hearing loss. Most SNHL is caused by cochlear fault. SNHL is considered by the inner hair cells and outer hair cells, or a combination of the damage caused. However, the underlying physiology are extremely complex. Different people have different pathological, this means listening to the same patient plan does not necessarily have the same type of hearing loss. Furthermore, patients or even on a different frequency range damage varies. SNHL results often leads to: 1) in some frequency channel has no input, 2) lack of sensitivity, and 3) auditory filter. In turn these results to a large extent on the injury the audience sound sleep. And compared to the normal audience, listeners who SNHL among other difficulties, most frequently encountered loudness revitalization (compared with normal, comfortable listening level range is compressed) and frequency resolution loss. Sound awareness of these changes significantly affected the ability of the audience to understand speech. Because SNHL just sound transmission problem is so simple, but in fact is the voice, through a simple zoom cannot treat this kind of loss-making vague voices greater cannot make them clearer. Therefore, to help a patient may SNHL effective ways is through preprocessing signal to enhance complex tone mode to compensate for hearing loss. By the same best treatment cannot cure SNHL manifestations. Handling sound enables speech easier to understand. However, the best processing algorithms vary by individual, even in different listening conditions (such as quiet and noisy Stadium) for individuals. Accommodate these differences lies in hearing aid of flexibility. Traditionally, hearing aid has been mounted on the right for the end user of custom ear moulds the amplifier. Hearing aid system includes a microphone, an amplifier, a zinc-air battery and a receiver/speakers. Most amplifiers employ some compression, it is non-linear input/output relationship used to compensate for loudness revitalization. You can also adjust the gain of different bands, bands number varies, but usually two or three bands. Many of the latest hearing aids are digitally programmable, which means that although they have an analog signal processing functions, but by audiologists may adjust the number of parameters to control processing. In addition, some analog hearing aids for different listening environments with multiple "program", or a parameter set. Some digital hearing aids on the market is with programmable coefficient of ASIC. The ASIC provides algorithm sets and multiple frequency band, this is the typical simulation equipment is not possible. For example, digital hearing aids have the following functions: 2 to 14 with adjustable crossover frequency band, a microphone, directional hearing dual microphones, background noise reduction, automatic gain control (AGC), speech enhancement, feedback and noise abatement. In short, to complete the processing of amazing, especially the simulations of hearing aids in traditional processing functions, and even more so. Design example based on DSP hearing aids scalable software control features, including the frequency shaping, feedback reduction, noise reduction, Binaural processing, ear shells and ear canal filtering, reverberation elimination as well as the provision from a digital telephone, television or other audio device direct digital input. Programmable DSP also means hearing algorithm/features can be customized or without changing hardware change. Hearing professionals almost in real time for economic use of the available algorithms. You can even be a user-selectable program is used to switch to hearing difficult cases are highly-processed sound, or return to the quiet environment of traditional, less distorted sound.

Figure 1: block diagram of a hearing aid DSP.

The above block diagram shows the DSP based on the main elements of a digital hearing aids.

Typical digital hearing aid consists of three mutually stacking of semiconductor bare chip: EEPROM or non-volatile memory, a digital deviceAnd an analog device. Latest allows those modules integrated into two or even a semiconductor bare chip. Because the battery voltage range 1.35V to 0.9V, these devices are designed to operate with 0.9V voltage. Some implementations use power management to monitor the battery voltage, and warn the user when the battery, the voltage drop too low, and close the system in a timely manner. Analog devices usually including Σ-Δ ADC with compressed input restrictions feature microphone preamplifier, remote control data decoder, clock oscillator and voltage regulators. Σ-Δ A/D frequency range usually 20kHz, a resolution of 16 bits (14-bit linear). Digital devices including DSP, logical support features, programming interfaces and output level. The output stage is typically a fully digital, use use speaker impedance of pulse width modulation (PWM) output and class d amplifiers perform analog-digital conversion. In short, current analog and digital hearing aids-power roughly equal. Analog devices total current consumption approximately 0.7mA-1.0mA, and digital equipment consumes 0.5mA-0.7mA. Section about providing 30mAh-65mAh and 50uA since discharge current of zinc-air battery power for this system. End-of-life approximately 0.9V voltage. As a result of the processing in digital hearing aid increased direct comparison between digital and analog hearing aids of power is not entirely fair. And analogue hearing aids equivalent with handling features of digital hearing aids consumes power even lower. Featured product AIC111: low power audio codec AIC111 is a low power DSP or microcontroller-compatible audio codec for personal medical equipment (hearing, auditory processing and low power headphones), as well as provide high-performance analog interface solutions. AIC111 support a 1.3V CMOS Digital SPI interface, and includes an external microphone power and bias power and low battery monitor and indicator.

Medical electronic platform choices: FPGA, DSP, ARM, or GPU X86? (1)

"MINDRAY for processor platform choice has two seemingly contradictory principles: the ' many ' and ' less '.

Where ' number ' refers to the diversity that we know neither the DSP, ARM, X86 or FPGA, GPU, each platform has its own advantages and drawbacks, so you can design products in accordance with their characteristics to select and match, the processor platform diversity and rational collocation can make products more competitive. "In the recently held the third China International Medical Electronics Assembly (CMET2010), Shenzhen MINDRAY bio-medical electronics hardware Technical Committee Executive Director, systems engineer, Yao and shared MINDRAY select processor platform's secrets," ' little ' refers to the greatest extent possible to reduce processor types, multiple processor platform will not only lead to trouble for manufacturing, research and development will greatly increase the human and capital inputs, each with a new processor platforms need to buy new software, training engineers and so on. Thus the tradition of MINDRAY is the first use of the processor platform to be successful in multiple products repeatedly apply, if you want to use a new processor, it must be approved by the technical committee hearings. ”

According to introduction, Yao force MINDRAY's star product portable color ultrasound is used in the M7 X86, FPGA, DSP and ARM, and so on multiple platforms with different work, of which the primary processor performance and prices are high for the Intel CORE 2 duo, signal processing using computing capacity more powerful FPGA and DSP together, the Panel adopts Nios II, power part of the use of the low-end of the ARM7 series products, fully embodies the MINDRAY select processor platform principles of "more".

Another principle of "least" is reflected in the same series of products once selected processor, future generations will use the same platform, almost never do.

3D touch technology can be used for remote medical

There was a friend of virtual participation in birthday party, or transfer a new product on trial for distant consumers, this sounds really incredible.

But according to physicist organization network recently reported that a "immersion" study (Immersence), in the EU 6th framework plan for the future and emerging technologies (FET) foresight project support, is this vision into reality.

This technology successfully consolidated the perception of the real world and virtual world impression, additionally trained therapists will be able to use it to do remote treatment, industrial designers can remote transmission on the Internet can touch the numeric entity model, etc.

Feel simulation, we are immersed in virtual reality the deeper.

Germany Munich University of technology of Andres ·, Wayne Borg said that more perception will bring more interactive, immersive feeling more strongly, the more the "immersion" in virtual reality.

As a three-dimensional scenery with touch arm

In recent years, audiovisual and more lifelike simulation and tactile areas has been dragged back leg.

Switzerland Zurich Federal Institute of technology (ETH) computer vision research laboratory scientists accept the "immersion" in a subproject, the Visual and tactile, dealing with people and the interaction between virtual goals and realize remote touch object.

Mathias · Mashhad and research other personnel first to real objects to produce a virtual copy, the copy can be touch, even in Internet transmission.

They use a soft toy frog, a record of its 3D scanning the image, while a tactile device — sensing arms to perceive it, and the Visual and tactile impression.

Sensor arm fitted with pressure, speed, and sliding sensors, able to move from any direction, collect overall, ruggedness, etc. After the measurement, calculation, a virtual frog is computer generated. In order to enhance the true feeling, they returned to the virtual frog design a real environment, so that his "crawl" in front of users on the table.

Virtual frog also can copy copies via the Internet to other people.

In order to let other people can see and feel the frog, researchers dedicated to virtual objects to design a data with a monitor and an eyepiece with small motor sensor. Virtual frog and sensor signals into contact, a computer program by calculating, simulation of objects of resistance when exposed to users of the campaign the impediment, making him feel as if I touch the frog, but in fact, he's just touch the air.

Early on the simulation of virtual target largely depends on the assumptions of researchers, and the ETH tool more based on measurement data.

Explain that this method can be thought of as an extension of camera technology, for those who are very difficult to model more complex objects is described.

The "immersion" virtual and where to dance

Germany Munich Polytechnic University is the "immersion" project of research institutions, Andres ·, Wayne Borg leadership, nine universities and research institutions to develop VR (virtual reality) goals and features haptic technology.

They develop a sense of touch and multiple model interface, use the signal process technology and real time generation of the reality of virtual objects, targets will allow people and virtual partner dancing together.

The researchers used a mobile robot platform, input records pressure, balancing, and live dance exercise programs, and then to a real person plus two arm as a partner, put on the dummy eyepiece, this person will be able to see a specific partner, lift the robot arm can and she dances.

In the virtual environment, the robot from computer operation, as another "' where da" (avatar).

These studies also contributes to the development of cognitive robots and humans interact better.

Reality and false Interactive Haptic technology

Now we can touch a virtual objects, but also can not catch it.

To have the feeling of the "grab", you need a special feeling glove, put on the gloves, users are able to touch the real objects, you can touch the virtual objects. ETH is developing this kind of gloves, Lienhard believe that gloves in the next 20 years will be like the Internet is widely used.

France El Tarif University also study how to two individuals with sensor for virtual common handling in a heavy box.

-Wayne Borg said that, in reality, this is a cooperative process, the robot interface must design a program that is not a people-driven and the other follows.

ETH computer vision research Switzerland has developed a table tennis game, reality only paddle joysticks, two players can blows virtual table tennis.

Their next project known as the "beam", intends to develop a long distance transfer method to transfer virtual person. Ahmad said that this will make it possible to participate in the teleconference, without having to personally help to save time and travel expenses. This is now the video conferencing more thoroughly, I feel like with other attendees to sit together, you can interact with other attendees.

Use the S3C2410 design 3-lead ECG Telemonitoring

Mainly introduces an approach based on three-lead S3C2410 platform remote ECG monitoring system.

The system is not affected by time and space constraints on real-time monitoring of heart patients, thereby facilitating patients and healthcare professionals to communicate at any time. After clinical testing by medical experts and heart disease.

1 introduction as the people's living standards, the acceleration of the pace of life, the incidence of cardiovascular diseases increased rapidly, has become a threat to human health is one of the major factors.

The ECG is the treatment of such diseases, principally, a diagnosis of reliable, easy to patients without prejudice, in modern medicine, are becoming increasingly important. Regular ECG is the patient lying by ECG record ECG activities, which lasted only a few s ~ 1 m, only a small amount for cardiac status obtained information, so for a limited time, even if arrhythmia occurs is found, the probability is very low. Therefore necessary to adopt appropriate care unit patients long live monitoring, recording patient ECG data. And since the incidence of heart attack with abrupt, patients could not possibly long lying in the hospital, but also need immediate medical staff care, research and development of the portable wireless ECG monitoring products becomes more important.

Currently, although country forming wireless ECG monitoring products, but its adoption of the programme are "collector + transmitter (PDA or cell phone)," and this will inevitably lead to its expensive, and PDA or cell phone's other features for the vast majority of patients completely unnecessary, so far internally practical wireless ECG monitor products areas or blank.

This remote ECG monitoring system is in the hospital on the basis of the proposal, after full investigation and design of the overall programme, the main achievement of the following features:

The system adopts the principle of ECG collection as shown in Figure 3. Including front-level differential amplifier adopted, its magnification 22.4 times; after amplification circuit magnification of 37 times, total magnification 828.8 times.

Figure 3 ECG collection principle because of the ECG to low-frequency signals in analog circuit design, to 100 Hz cutoff frequency of first-order low-pass filter to filter out high frequency interference, using second-order VCVS band-stop filter to filter out 50 Hz mains frequency interference.

In the digital processing, in order to curb on ECG effects larger frequency interference and baseline drift, with 2 048 point FFT on the input of a frame an ECG data — frequency domain transformation in time domain, and then remove 0.5 Hz low and below 50 Hz mains frequency; at the same time in order to suppress high-frequency noise and 50 Hz frequency disturbance and filter in addition to the frequency of 100 Hz and above, and then will this group data IFFT shift back to the time domain. 2.3 data wireless transmission module in the original location of this system to remote mobile terminals, wireless transmission of data involved, to implement this functionality using a Siemens MC35 module, the company and transfer the TCPIP protocol stack and the PPP protocol, to complete the ECG data of sending and receiving of diagnostic results. Siemens MC35 is the company launched the first support GPRS GSM/GPRS module, its small size, easy to integrate into a portable handheld Terminal, support for VOICE, DATA, FAX and SMS, and other services. Processor S3C2410 asynchronous serial communication interfaces are connected with the MC35, and through the at command to the module for control and data transfer. When sending data, first of all, the application tier will be collected by ECG data submitted to the TCPIP protocol stack; then, TCPIP protocol stack based on the destination address and port to the ECG data package to complete the IP datagram, and then submitted to the PPP layer; Finally, the IP datagram layer via PPP package, through serial byte by byte and submitted to the MC35 and send. When receiving data, the MC35 first receives the data byte by byte and submitted to the PPP layer; the PPP layer will be distributed to each byte of a frame to complete the IP datagram, then submitted to a detailed TCPIP layer, the specific process shown in Figure 4. The initialization to complete the startup and logon MC35 mobile Monternet gateway to establish a connection to the service provider. Generally send instructions before you send a test to detect the current state of the MC35, the directive has the form "ATr"; in access gateway and flow control parameters passed AT instruction sets are finished, you can start by service code and service call 99 providers connect, instruction format as ATDT * 99 *** 1 # rn. If in the directive after a given period of time CONNECT information returned, it indicates that the service provider; otherwise the connection is made successfully, indicating dial fails, wireless transmission function fails to start. MC35 successfully log Monternet gateway will automatically switch from command mode to data communication model, and serial communication mode from the original query type become disruptive. At this point the system actively send a frame PPP request information, the service provider receives the request for information is proactively ask frames, consultations related parameter settings. Question service parameters and user authentication succeeds, the service provider to assign a separate IP system, and thus can be considered successful GPRS on-line.

Figure 4 GPRS wireless data transfer process

After successful GPRS on-line can be considered two main Department MC35 operating state: data transmission status and idle.

In data transmission status, MC35 of peak current of up to 400 mA; in the idle state is generally 15 mA. In addition, in an idle state MC35 also supports a variety of sleep mode. Considering that the system power consumption issues, enabled the Hibernate feature MC35. The system adopts the MC35 sleep mode. In the sleep mode, the current General 3 mA or so; MC35 from serial port or from the service provider receives the data, it will immediately be MC35 is set to normal mode, data transmission ends automatically after entering sleep mode. The sleep mode setting can be done by Directive "AT + CFUN = 7rn" to complete, and that the directive must be performed after the GPRS on-line. This can be in idle state automatically MC35 set to sleep mode, the current value from 15 to 3 mA mA. In the sleep instruction execution before the switch State involved MC35, since in the implementation of the directive before the MC35 in data communication mode, through Directive "+++" to switch to command mode, and then execute the sleep instruction. After the sleep instruction execution also through Directive "MC35 ATOr" will switch to the data communication mode; otherwise, the MC35 will put the data to be sent as instructions. 2.4 graphical user interface in the original location system uses Shenzhen Pont far company production of low-power, 128 × 64 dot matrix LCD module MOBI2006 to graphical display system information. MOBI2006 supports both parallel and serial data communication, the working voltage 3.3 V. In this system, use the S3C2410 i/o port analog LCD control sequence to achieve the control of the LCD. In the specific implementation of the relevant information is displayed when you use a Framebuffer technology. First of all a pre-allocated buffer and declared as a two-dimensional array, the arrayThe length of a one-dimensional and two-dimensional length respectively and LCD's width and height, so that each element of the array represents a point in a liquid crystal. In the system operation to flush liquid crystal display, you must first update the Framebuffer buffer, then from the Framebuffer updates LCD display. MOBI2006 columns based on a points addressed; horizontal page addressing based, each page consists of eight dots. Characteristics of liquid crystal-based, if not using Framebuffer technology, refresh the screen in a small block will cause changes in the entire screen, to the development of the upper application has caused great difficulties. Therefore, although using Framebuffer technology will occupy part of the memory and the refresh time, but to the subsequent development of a convenient: in the upper specific application is no longer subject to the limit, the page address in the upper-level developers seem to, horizontal column are the points addressed, can facilitate flexibility to manipulate the Panel. In addition, in order to ensure the synchronization of the Framebuffer and LCD, using event-based method to refresh the LCD and a partial refresh, saving both time and LCD refresh reduces screen jitter. For example, the application layer to display a picture, the picture is displayed, which corresponds to a two-dimensional array of values, the image's width and height, and the corresponding bitmap data. First pictures of raster data is flushed to the Framebuffer buffer, and then under the display location determine LCD refresh ranges, which buffer column that corresponds to the column value, but the LCD row values to be converted to liquid crystal page value can be converted using the following formula: Page_end = (row + high-1)/8: Page_start and Page_end which correspond to the liquid crystals start, terminate page value; row corresponds to the picture shows the location of horizontal; high corresponds to the height of an image. Calculate the corresponding page value after they adopted the following procedure refreshes the specified region of the LCD, complete picture of the show is expected.

for(page=p_s;page<=p_e;page++) { fc=column;for(lc=l_c_b;lc>l_c_e;lc--) //2{ GUI_Lcd_SetALL((u8_t)page,(u8_t)lc);for(f_bit=7;f_bit>=0;f_bit--) { if(!(

Frame_Buffer[page*LCD_PAGE+f_bit][fc]))GUI_Lcd_SendData(0); elseGUI_Lcd_SendData(1); }Delay(10); fc++; }} 2.5 data storage management position in the original S3C2410 BANK0 extends 1 slice in 4M× 16-bit NOR FLASH; in BANK6 extends in a 8M× 16-bit SDRAM, and NAND FLASH by using the S3C2410 controller extends a 64M× 8-bit NAND FLASH. NOR FLASH is mainly used for storing program code; NAND FLASH is mainly used to store the collection of ECG data as well as part of the program code. S3C2410 support from NOR and NAND two ways to start, you can configure the S3C2410 of OM [1: 0] to select the startup mode of the CPU. The system can achieve full day 24 hours ' continuous ECG data acquisition, which will produce large amounts of data. To a large number of ECG data transfer to PC for analysis, diagnosis, medical staff, the system uses a common USB port. S3C2410 internal integration of USB Device controller, therefore only have to design simple peripheral circuits, you can implement this functionality. The USB Device controller is fully compatible with USB1.1 protocol specification, integrates USB transfer device that supports the control transfer, interrupt transmission and bulk; 5 the endpoint with the FIFO, the bulk of endpoint provides DMA interface and support for suspend and remote wake-up function. 3 closing this system has the very strong usability, you can carry out real-time monitoring of heart patients.

This article gives the application the ZTP135S — GE R type infrared temperature sensor design for thermometer.

2 infrared temperature sensor principle

Absolute zero temperature is higher than the existences (-273.15 ℃).

Because molecular thermal motion of all keep the surrounding space radiation including infrared band, electromagnetic waves. Its radiant energy density and the temperature of the object itself between the Planck (Plank) law. Infrared temperature measurement of the same principle, the principle is based on the Planck. General understanding of infrared measurements of the temperature of a body is, in fact, it is measured. objectives of the sensor or object and the difference between the environmental temperature. Objects the size of the radiation energy directly to the object's temperature. specifically, the object of the thermodynamic temperature of the 4-th power proportional to the expression using formulas to.: E = δ ε (T4-T4o) (1)

Type, E is the radiation emitting ° W/PCT unit is m3; δ is Stephen a Boltzmann constant, 5.67x10-8W/(m2 · K4); δ is the object of the radiation rate: T is the temperature of a body (K); To the objects surrounding environment temperature (K).

The main body for radiation wavelength 9 μ m-10 μ m IR. through the body's own radiation measurement of infrared energy will be able to accurately measure the surface temperature of the human body.

Because the wavelength range of the light is not absorbed by the air and, therefore, may also make use of the human body radiation infrared energy to precisely measure the surface temperature of the human body.

Infrared temperature sensor using a thermocouple measuring principle, the objectives of the sensor or object and the difference between the environmental temperature.

Principle of thermocouples are two different metal A and B form a closed loop, when the second contact end temperature while (T > To), loop generation thermoelectric Eab, where t is called hot end, end-To-end, or measure known as the cold end, open-end or reference client. A and B referred to as hot electrode. Thermoelectric power of size by contact potential (also called Burr veneer potential) and thermal EMF (also known as Thomson EMF).

3 ZTPl35S-R works and performance
