Continuous blood pressure measuring method and device based on volume pulse wave signal and equipment

Abstract

An embodiment of the invention provides a continuous blood pressure measuring method and device based on a volume pulse wave signal, equipment and a storage medium. The method includes: acquiring thevolume pulse wave signal of a to-be-measured object, wherein the volume pulse wave signal at least comprises a pulse wave period; acquiring a blood pressure feature value according to the periodic value of each pulse vale and the amplitude change value of the pulse wave from the starting point of each pulse wave period to preset time; inputting the blood pressure feature value into a pre-trained linear blood pressure model of the to-be-measured object to obtain the blood pressure value of the to-be-measured object. The method has the advantages that a cuff type blood measuring method which needs to wait for cuff inflation and deflation during blood pressure measuring is avoided, practical application is facilitated, and continuous blood pressure measuring is achieved; the blood pressure feature value uses the amplitude information and speed information of the volume pulse wave signal at the same time, blood pressure measuring accuracy is increased, the linear blood pressure model is simple in calculation, and blood pressure measuring efficiency is increased.

Description

technical field [0001] The embodiments of the present application relate to the field of blood pressure detection, and in particular to a method, device, device and storage medium for continuous blood pressure measurement based on volumetric pulse wave signals. Background technique [0002] Blood pressure is an important physiological parameter of the human body, which can reflect the cardiovascular function of the human body. The monitoring of blood pressure is an indispensable part of personal health management. In recent years, the incidence of high blood pressure in the population has been increasing, and often leads to complications such as heart disease and stroke, which seriously threaten human health. [0003] In the process of realizing the present invention, the inventor found that the following problems existed in the prior art: the traditional non-invasive blood pressure measurement method can be divided into two types: cuff type and cuffless type; wherein, the c...

Problems solved by technology

[0003] In the process of realizing the present invention, the inventor found that the following problems existed in the prior art: the traditional non-invasive blood pressure measurement method can be divided into two types: cuff type and cuffless type; wherein, the cuff type blood pressure measurement method has measurement The advantage of high accuracy, but because the blood pressure measurement needs to be inflated and deflated by the cuff, continuous blood pressure detection cannot be realized and it is not convenient for long-term use; the cuffless blood pressure measurement method needs to establish a blood pressure model, and the process of establishing a blood pressure model is complicated. Moreover, the accuracy of the blood pressure measured by the blood pressure model is not high.
