Design And Research Of Physiological Parameter Monitoring Terminal Based On Touch Screen Interaction

In China,the aging of the population has entered an accelerated stage,which affected by complex factors such as the improvement of living standards,medical conditions and the reduction of birth inclination.It bring huge and rigid demands to the medical and health industry and elderly care services,especially in the areas of home care and community care.Due to the huge size of the elderly sick population,the medical resources in hospitals and other large institutions is still insufficient,which leads to high cost of monitoring,especially in the vast rural areas.Based on these circumstances,this paper uses STM32 to design a low-cost,portable,touch-screen interactive real-time monitoring terminal for physiological parameters to realize realtime monitoring of physiological parameters such as ECG,blood pressure,body temperature and blood oxygen.The main tasks finished in the paper are as follows:(1)In this paper,the detection principle and signal characteristics of each physiological parameter ware studied.Appropriate measurement method ware selected and each signal acquisition circuit,central processing unit module circuit and power management module circuit ware designed in modules.(2)This paper finished the software work of monitoring terminal for human physiological parameters.In the work,the embedded real-time system(RTOS)and file system ware Transplanted,and the task design and GUI design of specific functional requirements ware also completed.Besides,the drivers of each acquisition module and the underlying equipment(SD card,TFTLCD)ware designed.It also made a study of the interference characteristics of blood oxygen signals and designed the signal processing program.(3)Finally,the running test of the monitoring terminal was Completed,whiched verified the reliability of physiological parameter collection.The monitoring terminal realized the interactive actions such as physiological parameter collection,waveform display,and data upload on the TFTLCD touch screen.The test results show that the device can work well and the design aim of research was achieved.The physiological parameter monitoring terminal designed in this paper is portable and easy to operate.It can realize real-time monitoring of physiological parameters such as ECG,blood pressure,body temperature and blood oxygen through touch interaction,and provide continuous and reliable physiological parameter monitoring services for home monitoring and community care,which is of great significance to the prevention and diagnosis of human chronic diseases.
