The "wisdom of the wise medical": experience on its three core technologies (1)

The beginning of 2009, a man named "IBM healthcare industry solutions Lab" bodies set up, it took a rather attractive word pushed to the front of us — medical wisdom.

Wisdom medical related to unified communications, video, wireless networking, sensors and RFID, is currently the latest and hottest technologies, thereby creating an integration of various applications of the information platform, to provide an unprecedented experience of wisdom.

Medical neurons

Wisdom of the medical core is the patient information delivery and sharing, including the information between different departments in hospitals, hospital, or even between hospitals and community, medical insurance, government departments, and other information.

This allows a called wireless sensor networks (Wireless Sensor Networks) the concept of the industry's hot topics. WSNs concept originated in the United States Defense Advanced research projects Agency in a research project. This wireless sensor networks combine sensing, computing, and networking capabilities are deployed in the whole hospital in its different sensor, sensing range surveillance and reconnaissance surroundings and and a specific destination instant status through a wireless network to these state information back into the main processing system. System managers in receipt of such information, to the patient's condition and make the appropriate changes.

Medical wireless sensor network requirements for distribution in the hospital, doctors, patients and equipment Department of sensor nodes with wireless communication capabilities.

Current wireless sensor network technology primarily uses ZigBee Protocol. ZigBee is a new kind of close-range, low-complexity, low power, low-cost wireless network technology primarily used for short-range wireless connections. By ZigBee, you can simply achieve a variety of devices, real-time online. Its low data rate and communication range of smaller features, determines the ZigBee technology suitable for bearing condition monitoring data traffic with the smaller business. ZigBee technology in thousands of tiny sensors to achieve mutual coordination and communication. These sensors have low energy, to relay through radio waves to move data from one sensor to another sensor, its communication efficiency is very high. Relative to existing wireless communication technology, the ZigBee technology is the lowest power consumption and cost of technology. ZigBee is the starting point for an easy implementation of low-cost wireless network. At the same time, its low-power performance can make use of battery-powered products for six months to several years of working time. This is very important hospital applications. It can ensure the deployment in the hospital all thousands of sensor to work long-term stability, not because of lack of power supply problems caused by information and maintenance headaches.

At the bedside of images

And traditional network construction requirements, achieve wisdom medical network infrastructure is no longer a bandwidth and transfer speeds, but network mobility and flexibility.

Therefore, wireless broadband in the realization of medical wisdom, becomes critical bearing technology. Comprehensive coverage of the modern hospital of wireless mobile networks can be diversified applications anytime, anywhere, guaranteed. In emergency situation happens, experts can do not need to look for computers to find information to help diagnose, but that was just a removable query to ensure that no one-minute delay.

The edge of the bed of the wireless information records and access to technology in Shanghai chest hospital may even be applied to the processing of medical images.

The hospitals primarily clinical orthopedic traction patients, fell seriously ill patients and patients with rescue. These patients often need bedside acquisition image data, this equipment mobility and wireless transmission of the information presented is very high. Chest hospital adopts new mobile CR system used at the patient bedside x-ray real-time collection job. This is a way of containing veneer CR reader, x-ray generator, PC workstations (with touch screen monitor), and portable power mobile CR System. But mobile devices still need CR digital image saved in the PC workstation, and operations staff checks all appointments for patients, to return to the Radiology Department then all image data through wired mode one-time upload to PACS System. Since then, the patient's doctor can consult the image data. This results in more patients, periodic access to image data. In addition, a special emergency patients are unable to meet demand.

Shanghai chest hospital Radiology Samuel will say: "for these new requirements, we propose a bedside radiographic digital and wireless transmission access PACS solution.

This is my home in the first new application, since moving bed particularity of photography and imaging data transport format of the standard requirements, the selection of photographic equipment and wireless receiving and transmitting equipment has an associated data interface, exchange requirements. Choice principle is to have reliable security anti-jamming ability, but also to keep sensitive and high speed of transmission characteristics. “

Shanghai chest hospital deployed smart wireless solutions included in the room of a Lee Ji Si MX-200R smart wireless controller and distributed in the in-patient Department building 17 Ward nurses station 30 MP-422A wireless access point, the conduct by the RingMaster wireless network planning, configuration, deployment, monitoring and optimization, precise control over all aspects of access management, including user, what, when, where, why, and access methods.

To complete the client deployment, you need to move the CR devices equipped with PC workstations installation support for 802 .11a/b/g wireless network card, so make the move with the CR system for wireless transmission capacity.

Digital Medical image data with large scale it to the network throughput capacity put new demands, according to computer room Director Sun Ke fen said: "usually a chest x-ray image data file is approximately about 5MB because clinicians on the chest, the computer-aided diagnosis of very high, subtle changes are likely the result of left and right diagnosis.

In order to ensure that inspection personnel in each nurse station can quickly collected radiological information uploaded to PACS systems, we use a uniqueSmart Wireless Smart Mobile architecture, the use of wireless access points have sufficient data-processing capacity.
