Wireless Gateway Recorder Supporting Medical Information Exchange between Zigbee Nodes and Bluetooth Devices

Nowadays more and more wireless technologies are introduced gradually to make health care more intelligent and portable. Particularly, Wireless Body Area Network (WBAN), which can collect and gather physiological data of the human body, plays an important role in realizing real-time monitoring and home health care. However, the single wireless technology inevitably exists shortcomings which may limit the application range of wireless technology in the medical care. Therefore, we designed the wireless gateway recorder which supports medical information exchange between Zigbee nodes and Bluetooth devices. As the hinge of Zigbee network and Bluetooth network, the wireless gateway recorder can take advantages of two kinds of wireless technologies. In this way, the application scope of wireless technology can be expanded in the medical care. In addition, the design provides storage function which means the data from WBAN can be stored in the Micro SD card of wireless gateway recorder. In the paper, we tested the feasibility of the design and applied the wireless gateway recorder in different scenarios of medical care. Test results show that the system works normally.
