摘要:

提出一种利用脉搏波传导速度法的血压测量方案。采用新型可穿戴式光电传感器分别采集人体左侧桡动脉和指端的脉搏波,摆脱传统袖带式的测量方式。通过分析脉搏波的波形,计算脉搏波传导速度,建立数学模型方程,对非侵入式的动态血压测量进行研究,并采用听诊法进行校准和误差分析,实现连续血压测量。实验结果表明,该系统测量方便,精度较高,与听诊法具有良好的一致性。

Abstract:

This paper presents a method for dynamic blood pressure measurement based on pulse wave velocity.The new wearable photoelectric sensors,rather than the traditional cuffs,are used to collect the pulse waves of finger and radial artery of the left side of body.Non-invasive blood pressure  measurement is achieved by analyzing the waveform of the pulse wave,calculating pulse wave velocity and building a mathematical model for non-invasive measurement of ambulatory blood.And we use the method of auscultation to make calibration and error analysis.The results show that the system,with the advantages of convenient measurement,high accuracy and good consistency by the method of auscultation,can measure the blood pressure continuously.

Key words: non-invasive blood pressure measure;pulse transit time;photoelectric sensors;wearable
