描述一种用8031单片机实现的基于测振法的无创伤血压监护仪,给出硬件的原理图和软件的算法框图。临床监护测量对照显示,该仪器较好地实现了设计意图。文章最后给出了能进一步提高系统性能的几个可能途径。
A non-invasive blood pressure monitor based on the vibration measurement method using 8031 single-chip microcomputer is described. The hardware schematic diagram and software algorithm block diagram are given. A comparison of clinical monitoring measurements shows that the instrument better fulfilled the design intent. The article concludes with a few possible ways to further improve system performance.
