Waveform characteristic point based method for analyzing volume pulse wave pattern and detection device

Abstract

The invention relates to a waveform characteristic point based method for analyzing a volume pulse wave pattern and a detection device, belonging to the field of electronic medical instruments. In the waveform characteristic point based method for analyzing a volume pulse wave pattern, the collection environment comprises a pulse wave pattern collection device and a computer, wherein the pulse wave pattern collection device is used for obtaining a digitalized volume pulse wave pattern and transmitting the wave pattern data to the computer and the analysis of the wave pattern is completed in the computer; the waveform characteristic point based method for analyzing a volume pulse wave pattern comprises the steps of: dividing the whole wave pattern into two parts of an ascending branch and a descending branch from the maximum point of the wave pattern; respectively acquiring the area characteristic quantity parameters of the two parts; and observing the relationship between the area of the parts and the area of the whole wave pattern to finally obtain the parameter. Shown in the research, the ascending branch and the descending branch of the volume pulse wave pattern respectively represent different physiology processes and the characteristic parameter obtained by the method represents the physiology states in detail.

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 acquired volume pulse waveform through computer technology, signal acquisition technology, digital signal processing technology, etc. Background technique [0002] The volume pulse wave is the pulsatile 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. Since the volume pulse wave is the blood flow volume pulse of the microvascular in the microcirculation, it is located at the distal end of the arterial system, so the volume pulse wave contains rich information on the microcirculation, as well as the closely related information on the microvascular function. [0003] In recent years, many scientific researchers at ...
