Embodiment 1

[0028] An embodiment of the present invention provides a method for measuring blood pressure, such as figure 1 As shown, the blood pressure measurement method includes the following steps:

[0029] Step S101, collecting the video of one body region and the video of another body region of the subject at the same time, the video of one body region and the video of the other body region both include multiple frames of images;

[0030] Step S102, extracting the gray value of one body region and the gray value of another body region in each frame of image;

[0031] Step S103, drawing the pulse wave waveform of one body region according to the gray value of one body region in each frame of image, and drawing the pulse wave waveform of another body region according to the gray value of another body region in each frame of image;

[0032] Step S104. Determine the pulse wave propagation time according to the pulse wave waveform of one body region and the pulse wave waveform of another...

Embodiment 2

[0060] The embodiment of the present invention also provides a blood pressure measurement system, such as image 3 As shown, the blood pressure measurement system includes: a video acquisition device 301; a gray value extraction device 302 connected to the video acquisition device 301; a pulse wave drawing device 303 connected to the gray value extraction device 302; connected to the pulse wave drawing device 303 The pulse wave transit time determination device 304; the blood pressure acquisition device 305 connected with the pulse wave transit time determination device 304.

[0061] The working process of the blood pressure measurement system is: first collect the video of one body region and the video of another body region of the subject by the video acquisition device 301, and transmit the collected video to the gray value extraction device 302; The extraction device 302 extracts the gray value, and transmits the gray value to the pulse wave drawing device 303; the pulse w...

Abstract

The invention discloses a blood pressure measuring method and system, relates to the technical field of medical treatment, and aims at improving the blood pressure measurement accuracy. The method comprises the steps of synchronously acquiring a video of one body area of a tested people and the video of another body area, wherein both the videos of the two body areas include multi-frame images; extracting gray values of the two body areas in each frame of image; drawing a pulse waveform of one body area according to the gray value of the body area in each frame of image; drawing the pulse waveform of another body area according to the gray value of the another body area in each frame of image; determining the pulse wave spreading time according to the pulse waveform of the two body areas; obtaining the blood pressure of the tested people according to the correspondence relationship between the pulse wave spreading time and the blood pressure. The method and system are applied to noncontact blood pressure measurement.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a blood pressure measurement method and a measurement system. Background technique [0002] Blood pressure is one of the important physiological parameters of the human body. Abnormal blood pressure can cause a variety of diseases, among which high blood pressure is one of the most common diseases that seriously endanger people's health. Therefore, the measurement of blood pressure is of great significance. [0003] Currently, mercury column sphygmomanometers are usually used to measure blood pressure. Specifically: first put the cuff on the subject's arm, inflate the cuff quickly, then deflate slowly at a constant rate, listen to the Korotkoff sound during the deflation process, and obtain the corresponding blood pressure value. When using a mercury column sphygmomanometer to measure blood pressure, the measurement error is relatively large, and the cuff needs to be in contac...
