【摘要】 为了能够更加清楚地了解一种可以连续测量的非接触式血压检测方法,介绍了基于脉搏波传导时间的能够在不接触身体的情况下完成的血压测量方法。详细叙述了采用脉搏波进行血压测量的发展史和两种不同的测量脉搏波传导时间的方法,以及基于两种测量方法的特征点提取和建模分析、血压计算方法等,并比较两种方法的优缺点。最后对采用脉搏波测量更多的生理参数进行了展望。更多还原

【Abstract】 In order to understand more clearly the non-contact blood pressure detection method, the blood pressure measurement method based on the pulse wave transit time can be conducted without contacting the body, and the blood pressure detection using the pulse wave is described in detail.The history of measurement is introduced. Two different methods of measuring pulse wave transit time, feature point extraction and modeling analysis based on the two measurement methods, and blood pressure calculation methods are also introduced. The advantages and disadvantages of the two methods are compared. Finally, the physiological parameters measured by the pulse wave are prospected.更多还原
