Design And Development Of Terminal Based On Embedded Technology For M-health System

Telemedicine improved the diagnosis and treatment in remote areas, reduced medical costs, enhanced medical resources sharing, realized long-distance diagnosis, tele-treatment, tele-surgery, tele-consultation, tele-monitoring, tele-detection, provides a broad space for the development of modern medicine. With the miniaturization, networking and intelligence demands of medical devices, telemedicine prompt many aspects of projects research.As the tendency of wearable medicine, M-health is the research focus of telemedicine in recent years, also weak link of it, and provides yet another means for emergency aid, long-distance diagnosis and real-time monitoring. Compare to the traditional telemedicine, M-health is not just difference from network model, its application makes great changes of business processes in hospital. So it is necessary and feasible as to strengthening health care, improving medical quality, and improving medical services.Today more and more medical equipment requires high-speed data acquisition, analysis and processing capabilities, more comprehensive care and treatment and power consumption low enough, the traditional 8/16 bit microcontroller present some limitations. Mobile market contains a wide range of mobile communications and portable devices, each product must balance performance and its power consumption. The embedded microprocessor with characteristics of low power consumption, rich resources on chip, widely used and high performance/cost value, which make it become standard solution of mobile devices.According to all above, we conduct an investigation about the application of embedded technology in medical equipment, then probe the possibility of M-health system realization with embedded technology, and finally design overall of a M-health system and research implementation of software platform construction of the terminal, signal acquisition, processing, analysis and so on in detail. As for hardware, the M-health system use ARM9 S3C2410 processor as its control core, DAQ data acquisition card combine with Labview to design signal generator, through AINO driven by the AD conversion for data acquisiton, and finally use the GPRS wireless network for ECG data transmission; while as for software, use vivi bootloader, linux kernel and device drivers consist of ARM-Linux+QT embedded environment, then do data compression base on that environment, Qt program application based on C/S architecture last.Designed terminal for M-health system based on embedded technology is with characteristics of miniaturization, intelligent and networking and so on combine with real-time ECG acquisition, data compression, wireless transmission of data to doctors and control center through GPRS networks, which will can speed up diagnosis with accuracy; patients on the client end can use SMS or phone to communicate with doctors which improve autonomy level for the treatment of patients; the monitoring center as the server end to receive information about the patients' physiological parameters; doctors may via SMS or phone to give medical advice, distribution of first aid treatment timely. Embedded solution for M-health will improve healthcare quality-greatly improve hospital business processes and medical services, also lower overall medical costs-which will have broad market prospects.
