血压是血液在血管中流动时对管壁所产生的侧压力,是心血管功能的重要指标。本文介绍了以我公司自主设计的基于ARM-CortexM0的SW1800单片机为控制核心,采用示波法进行血压测量的电子血压计。该设计具有低积小、功耗低、准确性高等特点。示波法测量原理示波法又称为压力振荡法,是一种比较先进的电子测量方法。它是利用袖带充放气的过程中检测袖带内的气体压力并提取微弱的脉搏波。通过
Blood pressure is the side pressure exerted on the wall of the blood when it flows in the bloodstream and is an important indicator of cardiovascular function. This article introduces the electronic sphygmomanometer which is based on ARM-CortexM0 SW1800 MCU which is independently designed by our company as the control core and uses the oscillometric method for blood pressure measurement. The design has a small plot, low power consumption, high accuracy and so on. Oscillometric method oscillometric method, also known as pressure oscillation method, is a more advanced electronic measurement method. It is the use of cuffs to deflate the gas pressure in the cuff during extraction and faint pulse wave extraction. by
