Blood pressure monitoring device in motion state, storage medium and equipment

Abstract

The invention provides a blood pressure monitoring device in a motion state, a storage medium and equipment. The device comprises a PPG waveform acquisition module used for acquiring PPG waveforms of a subject from a static state to a motion state, a static model building module used for building a static blood pressure monitoring model based on the static state PPG waveform, a motion characteristic parameter extraction module used for directly extracting characteristic parameters of the PPG waveform in the motion state and judging that a noise coefficient corresponding to each characteristic parameter in the motion state is smaller than a corresponding noise threshold value and a characteristic parameter value is within a corresponding preset threshold value range one by one, and if so, not changing the corresponding characteristic parameter, otherwise, updating the corresponding characteristic parameters in the motion state according to a pre-constructed function relationship between the characteristic parameters in the motion state and the characteristic parameters in the static state, and a blood pressure monitoring model correction module used for monitoring the blood pressure of the subject in the motion state by using the corrected blood pressure monitoring model.

Description

technical field [0001] The invention belongs to the technical field of blood pressure monitoring devices, and in particular relates to a blood pressure monitoring device, a storage medium and equipment in an exercise state. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] At present, blood pressure measurement methods are mainly divided into two categories: discontinuous measurement and continuous measurement. Discontinuous measurement mainly includes blood pressure measuring devices used in hospitals and homes, such as electronic sphygmomanometers and mercury sphygmomanometers. The cuff needs to be frequently inflated and deflated, and can only measure the blood pressure value at a certain moment, and cannot perform continuous dynamic measurement of blood pressure. The continuous ambulatory blood pressure measurement is divided into two ...

AI Technical Summary

Problems solved by technology

When the human body is in motion, various mechanical disturbances greatly interfere with the acquisition of physiological signals, and it is difficult to extract characteristic parameters from the PPG waveform

The inventor found that although signal processing methods such as filtering or feature extraction are used, very little useful information can be extracted, resulting in generally poor blood pressure monitoring accuracy under exercise
