摘要
采用了一种以反射式和透射式红外光光电传感器和单片机为基础,用同步检测心电信号、桡动脉脉搏波、手指脉搏波信号来测定桡动脉和外周动脉脉搏波传播速度的方法,研制一种无创的多段脉搏波传播速度检测系统。在软件编程中脉搏波周期信号的识别是以心电R波峰值为基准,同时再根据它们之间的时延关系进一步确定脉搏波的波峰与波谷的范围,提高检测准确性及精度。该系统通过检测心电、桡动脉脉搏波和手指脉搏波信号可获得多段脉搏波传播速度参数,具有较高的检测精度和良好的应用前景。
To design a non-invasive measuring system for multi-parameter pulse wave velocity, which is based on the reflection and transmission optical-electric sensor and a single-chip microprocessor. This system can obtain the pulse transit time of radial artery and peripheral artery through measuring the electrocardiogram （ECG）, the pulse wave of radial artery and fingers. The R wave peak of the ECG was used to identify the pulse wave, and the time delay relation between the ECG and the pulse wave was used to confirm the range between the pulse wave peak and trough in the software, so the measuring veracity and precision of the system could be advanced. This system can obtain multi-parameter pulse wave velocity parameter through measuring ECG, pulse wave of radial artery and fingers, indicating high detecting precision and potential application.
