Vascular endothelial function evaluation and detection system and method based on FMD

Abstract

The invention provides a vascular endothelial function evaluation and detection system and method based on the FMD. The blood volume pulse wave of a left fingertip and the blood volume pulse wave of a right fingertip are collected through a left fingertip blood volume pulse wave detector (81) and a right fingertip blood volume pulse wave detector (82) respectively. Pressurization is conducted on the brachial artery of a left arm or a right arm through a brachial artery pressurization cuff (9) so that blood circulation of the left arm or the right arm can be blocked. A host (4) calculates the vascular endothelial function situation index according to the changes of the left fingertip blood volume pulse wave area and the right fingertip blood volume pulse wave area before and after pressurization blocking of the brachial artery, the vascular endothelial function can be comprehensively evaluated, the blocking time of the brachial artery is shortened, and the system production cost is reduced.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an FMD-based vascular endothelial function evaluation and detection system and method. Background technique [0002] The human blood circulation system is a systematic whole composed of the heart and blood vessels. The vascular endothelial system is one of the largest functional organs of the human body. The integrity of the vascular endothelium and the normal function of the vascular endothelium are essential for maintaining the smoothness of the blood vessel wall and the smooth flow of blood. is of great significance. Normal vascular endothelium mainly has barrier function, receiving and transmitting information function and secretory function. Clinical studies have shown that regardless of cardiovascular disease or peripheral vascular disease, the common feature of both is vascular endothelial dysfunction. Such as stroke, myocardial infarction, ischemic nephropathy and inter...

Problems solved by technology

However, the PAT method still has deficiencies. The main reason is that when the information is collected, the time of blocking the brachial artery is too long, which makes it difficult for the subjects to accept, and the critical point is only obtained by the change rate of the fingertip tension pulse wave amplitude, which misses the pulse wave. other active ingredients, so it is not possible to more fully evaluate vascular endothelial function
