Model training method and device and blood pressure measurement method and device

Abstract

The invention provides a model training method and device and a blood pressure measurement method and device. The model training method includes the steps of obtaining heart beat signals, blood pressure information and personal information of a subject; extracting heart beat feature information from the obtained heart beat signals; adopting the extracted heart beat feature information and personalinformation as input features of a blood pressure measurement model, adopting the obtained blood pressure information as an output result of the blood pressure measurement module, and conducting training to obtain the blood pressure measurement model for measuring blood pressure of a user. According to the provided model training method and device and the blood pressure measurement method and device, by training the blood pressure measurement model capable of automatically measuring blood pressure to help the user measure the blood pressure, the purpose of continuous measurement of the bloodpressure is achieved, the problem that the daily life of the user under a cuff inflation measurement mode is interfered can be avoided, and the use experience is great.

Description

technical field [0001] The invention relates to the technical field of blood pressure measurement, in particular to a model training method and device, and a method and device for measuring blood pressure. Background technique [0002] Blood pressure is an important parameter reflecting the function of the human circulatory system. It refers to the lateral pressure of blood on the vessel wall per unit area caused by the pumping activity of the heart, which changes continuously and periodically with each cardiac cycle. Among them, when the ventricles contract, blood flows from the ventricles into the arteries. At this time, the pressure of the blood on the arteries is the highest, which is called the systolic pressure; The pressure is called the diastolic pressure. Since the fluctuation of blood pressure changes every moment, designing a continuous blood pressure measurement method to understand the diurnal variation of blood pressure (ie, systolic blood pressure and diastol...

Problems solved by technology

[0004] However, although the above-mentioned ambulatory blood pressure measurement method can measure blood pressure fluctuations within 24 hours, it reflects the instantaneous value of blood pressure in each measurement time period, which cannot really achieve the purpose of continuous blood pressure measurement, and because each measurement It is necessary to inflate the upper cuff every time, which will seriously interfere with the daily life of the user, and the user experience is not good
