摘要
通过对多款常用的国内外电子血压计的血压实验测试,发现对高血压或低血压情况进行测量时,存在着由于最大充气压力与本次血压测量不符,而带来反复充放气和充气压力过高的问题。为了解决这些问题,找到合适的最大充气压力,提出了两个基于脉搏波识别的智能充气方案,并进行了700组血压实验,对两个方案进行实验验证。实验证明所提出的两个方案具有很好的稳定性以及准确性,可以有效地解决血压计测量中的问题,同时得出了方案二即在充气过程中预估最大充气压力为最优方案。
Through various common domestic and foreign electronic sphygmomanometers to test blood pressure, we find that when measuring high blood pressure or low blood pressure, there is a mismatch between the maximum inflation pressure and the blood pressure measurement, which often results in repeatedly inflating and deflating as well as the problem of high inflation pressure. In order to solve these problems and find a suitable maximum inflation pressure, two intel igent pneumatic solutions based on identifying of pulse wave are suggested and 700 groups of blood pressure experiments are done, then the two solutions are verified by experiments. The experiment proved that these solutions proposed have good stability and accuracy, they can solve the problems appeared in measuring blood pressure effectively, at the same time, the second solution that estimate the maximum inflation pressure during inflation is considered as the best one.
