脉搏信号采集系统的研制

摘要

In view of the traditional Chinese medicine diagnosis depends on the experience on the skin contact between doctor and patient,the doctor may make accurate judgment sometimes because of their own or environmental interference.Based on the principle of photoelectric displacement method,a kind of pulse signal acquisition system using optical principle was developed.It can display oximetry pulse condition,and physiological information of measured object ot real-time,realize the transmission and storage of information through the serial communication with the host,and provide reliable data for the doctor.%针对传统的中医脉诊要依靠有经验的医生与病患皮肤接触、有时会因为自身或环境干扰存在不能准确判断的问题,基于光电容积法原理,研制一种采用光学手段检测脉搏信号的采集系统.该系统可以实时显示被测对象的脉象、脉率等生理信息,并可以通过串行通信与主机相连实现信息的传输与存储,为医生提供可靠的数据.
