摘要
血压和脉搏是人体重要的生理参数,准确地测量血压和脉搏对人体的健康起着十分重要的作用。该装置基于脉搏波时间变化特征的测压原理,选用专用传感器BP300实现了准确的压力传感,使用8位单片机ATMEGA16对信号进行处理,将收缩压、舒张压和脉率值在LED数码管上循环显示出来。整台仪器具有使用方便、显示直观的特点。
The blood pressure and the pulse are two of important physiology parameters of human body, accurate measurement of the blood pressure and the pulse are playing vital role to the human body health. The principle of this instrument is pulse wave characteristic of time. It chooses the special pressure sensor BP300 which converts precisely the pressure signal to voltage signal and makes signal processing by the 8-bit SCM- ATMEGA16. The LED displays circulatory the results- systolic pressure, diastolic pressure and pulse. The instrument can be used conveniently and the results are presented obviously.
