摘要
介绍两种无创自动测量血压计—听诊法(又称柯氏音法)血压计和示波法(又称振荡法)血压计的工作原理,指出导致测量准确度不理想的原因。通过仔细观察传统听诊器法水银血压计测量血压的过程,发现伴随着柯氏音响的同时,水银柱会抖动。可根据水银柱第一次抖动和最后一次抖动确定收缩压和舒张压的现象,认真分析提出了准确度能大幅提高的等效听诊法无创自动测量血压计。指出在现有示波法无创自动测量血压计的基础上,实现等效听诊法无创自动测量血压计,不仅完全可行,而且非常简易。
In this paper, the authors described the existing two non-invasive automatic methods for blood pressure measurements of auscultation blood pressure measurement and oscillography blood pressure measurement and explored the cause for its inaccurate measurement. Through the observation of measuring the blood pressure with tradition mercury blood pressure measurement process, we found that mercury wobbled with sound. According to the first jitter sure systolic blood pressure and the last time jitter sure diastolic blood pressure, we concluded that we can greatly improve the accuracy of non-invasive automatic measure blood pressure measurement with equivalent auscultation. Based on the existing methods, non-invasive automatic measure blood pressure measurement with equivalent auscultation is simple and feasible.
