Research On The Key Technology And Application Of Intelligent Physiological Parameter Detection

With the continuous development of science and technology, the medical model of prevention, treatment and control of the disease has gradually developed into the digital and intelligent direction. Intelligent monitoring of vital signs parameters is helpful to the health care workers to master the changing trend of health status, and understand the development process of the disease.Intelligent physiological parameter detection mainly fuses sensor technology, embedded technology, wireless communication technology and computer software technology. It can gather and intelligent controlthe area of physiological parameters through the mutual cooperation of each system of acquisition, and the data is transmitted to a data center for data exchange through wireless communication. Intelligent monitoring of vital signs parameters has broad application prospects in the military and national defense, Bio Medical, disaster relief, and the aviation and aerospace field.In this paper, according to the requirement of intelligent physiological parameter detection system, the three key technologies are studied. The first is ectopic pulse wave acquisition; the second is physiological parameters in the design of wireless transmission and receiving scheme; the last is the effect of micro gravity environment on measurement results of noninvasive blood oxygen saturation.In the research of the key techniques of ectopic pulse wave acquisition,this paper mainly completed the design of the hardware circuit of the axillary pulse wave acquisition, and realized the acquisition, processing and display of the axillary light capacitance and pulse wave signal. For wireless repeaters and receiver design research, this paper mainly completed the design of hardware circuit and the preparation of software program for the repeater and receiver, and achieved the accurate and efficient wireless receive and relay life sign data and upload to the PC software by using Hash list to improve the communication efficiency. In the key technology research ofnoninvasive oximetryin a microgravity environment, this paper mainly studied the impact of microgravity environment on animal blood oxygen saturation measurement results. The main work included the research of animal modeling methods of simulated microgravity environment, determination of the animal experiments program, collecting the non-invasive and invasive oxygen saturation value of animals, and carrying on the contrast analysis to the data.According to the results of the data analysis, it can be concluded that noninvasive measurement of blood oxygen saturation is not accurate in microgravity environment, noninvasive oximetry does not apply to the microgravity environment.
