摘要
针对血压连续测量问题,设计了一种基于脉搏波传导时间的系统。该系统通过采集人体心电信号和光电容积脉搏波信号,将数据通过WiFi传输到计算机终端,采用差分阈值-窗口法提取特征点,计算脉搏波传导时间,拟合出人体血压值。通过采集一定的实验数据验证了本系统能够达到连续测量血压的目的,可为医护人员掌握病人身体状况提供重要依据,具有良好的应用前景。
A design based on pulse transmit time for continuous blood pressure measurement is introduced. Insignal and photopletliysmograph signal are collected and transmitted to a computer through WiFi,then the feature points are extracted and thepulse transmit time is calculated,and finally the blood pressure is analysed. This system is verified to measuring,and has great practical value.
