Abstract:
Embedded computing and wireless communication technology were used to develop a mobile biotelemetry system, featuring the functions of mobile measurement, wireless transmission, database archival, and internet retrieval of biomedical signals. Two PPCs (Pocket PC) with WLAN (wireless LAN) PC cards were used to simulate the communicating situation of biomedical signals between wireless sensors and a personal monitor. A PPC client program simulated the wireless sensors and a PPC server program simulated the personal medical monitor. Medical PDA was implemented by SBC (single board computer), LCD display, touch screen and Bluetooth module. Windows CE.net was ported as its operating system and the application program was developed using embedded Visual C++ 4. The measured transmission speed of ECG data was 2150 samples per second in the WLAN environment. For wireless internet connection, a Web-based server program was developed, able to display the biomedical signals of remote patients and be remotely monitored by medical doctors in a distant hospital. PDA data, which was archived at the server's database table, was transformed to an XML message and could be displayed on a Web browser as a signal graph. This system would be very useful for patients with chronic illness, especially in an emergent environment, and for containing medical cost in the aged society.
