Abstract

The present invention relates to a method for continuously measuring blood pressure and its equipment. Said method is characterized by that it creates a regression equation between pulse wave conduction time and arterial pressure: BP=a+b*PWTT for measurand person; and utilizes personalization correction technique to define intercept and regression coefficient b of measurand person. Besides, said invention also provides a method for continuously obtaining pulse wave conduction time PWTT by using pulse wave of human body, electrocardiogram signal and phonocardiogram signal and its concrete steps. Said method can raise accuracy for continuously measuring blood pressure, and can be used for measuring head blood pressure.

Description

technical field

[0001] The invention belongs to a method and a device for obtaining relevant data in the measurement of human arterial blood pressure, in particular to a method and a device for obtaining relevant data in the non-invasive continuous blood pressure measurement of the human body. Background technique

[0002] Blood pressure measurement methods can generally be divided into two categories: invasive measurement and non-invasive measurement, and non-invasive methods can be divided into two categories: intermittent and continuous. Intermittent measurement is the blood pressure value at a specific measurement moment. Since the pressure of blood on the arterial wall is changing at each heartbeat and at each time point in each beat, the systolic blood pressure and diastolic blood pressure measured by this method are not necessarily the representative blood pressure of the subject, and they are not the same time. Numerical values ​​in heartbeats. Continuous can measu...
