The Research Of Key Technologies On The Multi-Physiological Parameters Tele-Monitoring System

Currently, with the increasing of average lift and the decline of birth rate, many developed and developing countries have to face the population aging problem. It also courses many social problems about elder's health care. Some chronic diseases need long-term monitoring, or need to get physiological parameters during the diseases coming on, while present monitor methods limit the patients in the hospital. Telemedicine can solve problems such as releasing the burthen of hospital or the high cost and inconvenient. The telemonitoring of physiological parameters has become a focus of study in the field of biomedical engineering. Hence, this paper researches the key technologies of real-time multi-physiological parameters telemonitoring system.A multi-channel central monitoring system based on B/S mode is designed. It's consistent of the central monitoring server software, the Internet Explorer in the client PC, and a physiological signal collector. The server software can accept two client's request of data transfer, and real-time monitor several patients through Internet. The client uses the B/S mode, and needn't install any software. The only thing should to do is opening the Internet Explorer, from which the waveform and signals are shown and transferred. The system extends the central monitoring service from hospital to the community, and is benefit for patient's long-term observation and cutting fees.Additionally, the audio function has been added in the telemonitoring client software based on P2P mode, which developed by us previously. It's can help patient communication with doctors just at home, like a telephone via Internet.After software designed, the system has been tested. In the audio communication, the voice is clear and with little delay. The ActiveX control developed by C# can run in the Internet Explorer, and the data can be transferred to the monitoring center correctly. The remote central monitoring is realized. The B/S mode telemonitoring system, running in the Internet Explorer, is simple to deploy and maintain. It can be a new solution of network based health care devices.
