Method and detection device for analyzing volumetric pulse wave pattern based on waveform feature points

Abstract

A method and a detection device for analyzing volumetric pulse wave images based on waveform feature points belong to the field of electronic medical instruments. A method for analyzing volume pulse waves based on waveform feature points, comprising an acquisition environment composed of a pulse wave image acquisition device and a computer, the wave image acquisition device is used to obtain a digital volume pulse wave image, and transmits the wave image data to the computer , complete the analysis of the wave map in the computer, and analyze the method of the volume pulse wave map based on the waveform feature points, that is, divide the whole wave map into the ascending branch from the maximum point of the wave map and reduce it to two parts, and obtain the two parts respectively The parameter of the area characteristic parameter, and then investigate the relationship between the area of ​​each part and the area of ​​the whole wave map, and finally get the parameter. Studies have shown that the ascending branch and descending branch of the volume pulse wave map represent different physiological processes, and the characteristic parameters obtained by the above method can represent each physiological state in more detail. The pulse diagram analysis method and device thereof of the present invention have the function of prompting microangiopathies.

Description

technical field [0001] The invention belongs to the field of electronic medical instruments. It is a method and device for evaluating microvascular function by automatically analyzing and discriminating the collected volume pulse wave waveform through computer technology, signal acquisition technology, digital signal processing technology, etc. Background technique [0002] The volumetric pulse wave is the pulsating change in the blood volume of the microvessels when the arterial blood flows through the microvessels such as arterioles, capillaries and venules in the peripheral blood vessels under the beating of the heart. Because the volume pulse wave is the blood volume pulse of the microvessels in the microcirculation, it is located at the end of the arterial system, so the volume pulse wave contains a wealth of information about the microcirculation and the microvascular function closely related to it. [0003] In recent years, many scientific researchers at home and abr...
