摘　　要：现有的基于桡动脉脉搏波的心血管功能参数检测仪能够无创地检测心血管参数,但要求使用者具备一定的医学知识,需人工判断用于检测心血管功能参数的脉搏波波形,从而降低了仪器的普适性。本文利用小波变换对脉搏波进行分析,实现了一种新的基于连续小波变换的桡动脉脉搏波检波算法。实验结果表明:该算法准确性好,能有效提高心血管功能参数检测的智能化程度,降低操作难度,有利于心血管功能检测仪在家庭医疗保健中的推广使用。At present, the hemedynamic parameters can be detected widely by using the instrument based on the pulse wave of radial artery, however operators are demanded to have certain medical knowledge to artificially detect a waveform used to compute hemedynamic parameters, that limits the instrument＇ s application in fact. As a result, we propose a new algorithm, making use of wavelet analysis, to detect pulse waveform of radial artery. Experiment results show that this algorithm has good accuracy, can improve the intelligence of instrument detecting hemedynamic parameters, and can simplify operation. The result benefits the popularization of hemedynamie parameters detection in family health care.
