Blood pressure detection method and device, equipment and medium

Abstract

The invention relates to the field of data processing, and provides a blood pressure detection method and device, equipment and a medium. The method comprises the following steps of obtaining a fingertip video in a preset time period and user characteristic information of a to-be-detected user; performing channel conversion on the fingertip video to obtain PPG signal data; extracting PPG signal effective data in the PPG signal data; when the preset duration requirement is met, performing signal preprocessing to obtain PPG signal template data; inputting the PPG signal template data and the user characteristic information into a blood pressure detection model, obtaining first characteristic data through blood flow pulse characteristic extraction, and obtaining second characteristic data through one-hot coding conversion; and obtaining an output result of the current blood pressure parameter value through cross characteristic blood pressure prediction. According to the invention, the blood pressure parameter value of the to-be-detected user is automatically detected through a mobile terminal, the convenience is improved, and the blood pressure detection accuracy is improved. The method is suitable for the field of smart medical treatment and the like, and can further promote the construction of smart cities.

Description

technical field [0001] The invention relates to the field of data processing of big data, in particular to a blood pressure detection method, device, equipment and medium. Background technique [0002] Blood pressure refers to the lateral pressure on the wall of the blood vessel produced by the blood pressure flowing through the blood vessel when the heart contracts. It is the result of the joint action of ventricular ejection and peripheral resistance. An important basis for follow-up medical behavior. [0003] At present, the traditional non-invasive blood pressure detection technology is roughly divided into intermittent measurement and continuous measurement. Although the intermittent measurement method has the characteristics of high accuracy, it has high requirements on the operator (professional medical personnel are required to operate), and it is inconvenient to carry, so blood pressure cannot be measured at any time, and only intermittent blood pressure values ​​c...
