Development of Handheld Miniature Multi-Physiological Parameter Monitoring Equipment

为解决传统生理参数检测设备功能单一、体积庞大、使用不便的问题,本文设计了一款手持式微型多生理参数监测设备。该设备以STM32F411为主控芯片,搭载用于生物电势测量的模拟前端ADS1292R和血氧测量的集成模拟前端AFE4490等检测芯片,实现心电、光电容积脉搏波和体温等信号的采集,最终通过信号处理和数据解析,完成心率、血氧、血压、体温等生理参数的测量,达到用户家庭日常健康监护与诊断的需求。该设备集多种生理参数测量于一体,操作简捷,携带方便,解决了传统测量设备的依从性问题,满足了现代人群实时检测多生理参数的需求。

In order to solve the problems of single detection function, large volume and inconvenient use of traditional physiological parameter detection equipment, a hand-held miniature multi-physiological parameter monitoring equipment was designed. The device used STM32 F411 as the control chip, equipped with analog front-end ADS1292 R for biological potential measurement and integrated analog front-end AFE4490 for blood oxygen measurement. ECG signal, photoelectric volume pulse wave signal and body temperature signal were collected and analyzed to achieve the physiological parameters of heart rate, blood oxygen, blood pressure, and body temperature. Compared with traditional equipment, the device was suitable for daily family health monitoring and diagnosis. The equipment has the characteristics of multi-parameter measurement, simple operation and convenient carrying, which solves the compliance problem of traditional measuring equipment and meets the needs of modern human to multi-physiological parameters detection in real time.
