摘　　要：为解决当前国内无创连续血压测量技术难以实际应用的问题,研制了一套高性能的同步心电、脉搏信号采集系统,搭建了PC端人机交互软件平台,并集成了连续血压测量相关算法。该系统完成了基于同步心电图(electrocardiogram, ECG)和光电容积脉搏波(photoplethysmography, PPG)信号的脉搏波传导时间等多个特征参数的提取,实现了无创连续血压的测量。为验证系统测量的准确性,进行了测试与对比验证。结果表明,该系统满足相关标准要求,具有良好的应用价值。To address the issue of the difficulty in implementing non-invasive continuous blood pressure measurement technology in China,this study developed a high-performance synchronous electrocardiogram(ECG)and photoplethysmography(PPG)signal acquisition system.A PC-based human-computer interaction software platform was constructed,and continuous blood pressure measurement-related algorithms were integrated.Multiple feature parameters such as pulse wave transit time based on synchronous ECG and PPG signals were extracted,enabling non-invasive continuous blood pressure measurement.To verify the measurement accuracy of the system,tests and comparative verifications were carried out.The results demonstrated that the system could meet the requirements of relevant standards and have good application value.
