Perspective of the ABCD IV medical device, look for the electronic technology for maximum value-

Electronic technology's contribution to medical science is obvious to all, who can envision the physician doctor without the aid of medical electronic devices is what status? e technology, extended or save human life for electronic engineer sense soar; at the same time, be able to make use of the medical industry is increasingly weak profits of electronic products to inject more added value is also extreme concern to manufacturers '.

Due to human security will have a direct or indirect impact on medical device product classification is set, the global coordination of the working group to develop a world wide standard medical equipment is divided into the following A, B, C, D grade: 4

A-level refers to when a failure occurs, the harm to the human body produces very low product, such as x-rays, scalpel, tweezers, stainless steel small appliances, and surgical non-woven cotton wool, gauze, medical, and surgical knife lighting equipment, special apparatus and Stomatology surgery microscope, home first aid bandage;

B level means less harmful products such as blood analyzers, x-ray diagnostic equipment, medical CT, ultrasound, magnetic resonance imaging (MRI), electronic thermometer, electronic sphygmomanometer, electronic stethoscope, electromagnetic blood flow, heart rate monitor, ECG, EEG, EMG, vital capacity meter, electronic lung capacity meter, Oximeter, endoscopy, Capsule Endoscope, blood cell counter, oxygen, low-frequency infrared treatment instrument, medical equipment, microwave treatment instrument, ultrasonic therapy equipment, home electronic Massager, hearing aids, etc.;

C is more risky products, such as continuous blood glucose meter, dialyzer, artificial heart lung machine blood pumps, ventilators, implanted hearing aids, heart defibrillator, extracorporeal cardiac pacemaker, infusion pumps, selves testing glucose meter, etc.

D is the implantable cardiac pacemaker, implantable defibrillators, implantable syringe, implantable aided artificial heart system high risk products.

In this four-level, B, C, D-level needs to be involved in electronic technology, and obviously, the higher the risk level of the product on electronic technology requirements are higher, appropriate, and constantly update the breakthrough of electronic technology to drive the few areas of innovation.

Higher accuracy, smaller medical imaging

A combination of optical, electronic, biomedical technologies, Biomedical Optics in B-class medical-grade equipment is very wide, and covers the optical treatment, medical imaging and Bio-sensing, main applications include clinical lesion of early diagnosis and monitoring, or light guide, inspire-related diseases.

It is estimated that sales of related products for the year 2010 is expected to achieve global 598 billion, accounting for 22% of medical equipment.

From a specific product, from the x-rays, magnetic resonance imaging (MRI), Masako tomography Imaging (PET), CT, ultrasound, radiotherapy, Photodynamic therapy, physiological signal monitoring, in vitro diagnostic and biochips are included in the areas of bio-medical electronics.

The application of the previous types of imaging technology is the overall medical technology market share of the largest areas of development is more mature and competitive, as market demand gap, not only renowned international manufacturers and local manufacturers competition is quite intense, more manufacturers are constantly trying to enters that area.

Continuously improve the resolution and continuously reduce the volume of the device is a medical imaging two major trends in the field of the new system-on-demand means that the analog semiconductor manufacturers have developed ground-breaking Foundation IC, active semiconductor manufacturers to introduce their products, such as TI for ultrasonic imaging applications AFE58XX analog front end series, ADI for CT applications by Xilinx and Altera ADAS1128, etc for high-resolution image processing and high performance data analysis of FPGA, Austria microelectronics for DR and CT applications of high precision amplifier and sensors.

In addition to using optical imaging technology, innovation can be ingested by endoscopy (also known as capsule endoscopy) broke the inherent shortcomings of conventional endoscopy, which can effectively be human image back to the outside.

Latest capsule endoscopy to sensors and circuits placed in capsules, when patients swallow the capsule will after in vivo and 360 ° rotation, plus the circuit containing for lighting of the led, can be effective in vivo images back to the external device. But the technology is still in its infancy, the future of universal also need cost and performance improvements.

Science fiction-like legendary implantation techniques

Let the MEMS applications fiery is consumer electronics, medical and diagnostic equipment for MEMS applications provides a larger arena.

More and more applications creativity will MEMS technology and medical perfect together, and thus the benefit of mankind. Than the Ruyi method Semiconductor for Switzerland Sensimed AG designed a MEMS sensor embedded wireless, embedded with a contact lens micro strain gauge continuously over a period of time (usually 24 hours) monitoring the curvature of the eyes, in addition to the lens also embedded antenna, mini specialized processing circuits and sent to the receiver RF transmitter measurement data.

In the application of bio-medical MEMS has also been in actual growth in clinical medicine use sensors and intelligent control technology for the treatment of pulmonary tuberculosis and heart disease, heart of incentives and dredging.

Innovation application including a revolutionary Proteus Biomedical company: implanted electrodes, it can stimulate the heart within different cavity location make them for synchronization or synchronization heart treatment. Its core technology is manufactured using a chip scale package technology, mm level dimensions of MEMS sensor and processor packaging system in the body's internal use, and can be maintained for many years, to avoid the traditional must use more insert catheter to stimulate the heart of different locations.

Implantation techniques like science fiction as legend, belonged to the risk level of C and D class equipment.

The implantation of the product categories for heart disease treatment and next will focus on in the brain, such as electronic nerve stimulation device therapy from drug addiction to epilepsy, Parkinson's disease and depression and other disorders.In fact, at this stage the world about one third of the health problems associated with neural areas. Large Medtronic pacemaker companies have developed for the treatment of Parkinson's and other minor diseases of equipment, and is developing a series of neural implant products.

Dependent on the progress of electronic technology, global medical electronics field are examples of the continuing innovation, future medical and Electronics will more closely, thus creating a stronger, more innovative medical devices.
