CONTINUOUS AMBULATORY BLOOD PRESSURE MONITORING DEVICE AND METHOD BASED ON PULSE WAVE TRANSIT

摘要

A continuous ambulatory blood pressure monitoring device and method based on pulse wave transit time and pulse wave transit velocity. In the continuous ambulatory blood pressure monitoring device, a host housing (101) having a watch shape is equipped with an electrocardiograph signal collecting module (104), a pulse wave signal collecting module (103) is provided on a wristband (102) at the position facing to the wrist radial artery, and the electrocardiograph signal collecting module (104) and the pulse wave signal collecting module (103) signal connect to a control module (105). The continuous ambulatory blood pressure monitoring device and method can obtain pulse waves in real time, and solve the problem of poor heart pulse wave acquisition in vitro. A quick and accurate method for obtaining the time point of cardiac ejection is provided, and the method is an important part of the continuous ambulatory blood pressure monitoring.
