Embodiment Construction

[0032] Relevant detailed description and technical content of the present invention, now just explain as follows with respect to matching drawing:

[0033] It must be explained that the flow of blood in the human body is not entirely caused by the contraction of the heart to push the blood. Another part of the reason is that the blood vessels of the human body are elastic, and they can elastically expand and then contract when the blood passes through to push the blood. Blood moves forward. Therefore, according to Hooke's law, the characteristics of the vessel wall can be modeled with an elastic component and a damping component, and the simulation of the model can be carried out as follows:

[0034] ∂ 2 P ( z , t ) ∂ t 2...

Abstract

The invention provides a method to measure arterial elasticity and arteriosclerosis includes a measuring step and a sampling step to obtain a pulse waveform which represents the displacement of an arterial wall during elastic dilation and contraction. The method of the invention also includes a first differentiation step and a second differentiation step to respectively obtain a first differential pulse waveform and a second differential pulse waveform. The evaluation data is obtained when the arterial wall dilates to the maximum thereof. In an evaluating step, the maximum elastic force represented by the second differentiation of the maximum displacement of the arterial wall is divided by the maximum displacement of the arterial wall to obtain an arterial elasticity coefficient to determine extent of arteriosclerosis and prevent cardiovascular diseases. The present invention has advantages of noninvasive and direct evaluation to arterial elasticity, easy operation, high accuracy and low cost and thus has very high utility.

Description

technical field [0001] The present invention relates to a detection method of biotechnology, in particular to a detection method of blood vessel elasticity and hardening degree. Background technique [0002] Due to the gradual change of modern eating habits, it is becoming more refined, and people prefer oily or high-salt foods, which makes people suffer from arterial hardening, such as cerebrovascular disease, heart disease, high blood pressure, etc. Diseases tend to increase. How to effectively detect the elasticity of arterial vessels to prevent the occurrence of diseases in advance is a common goal that people expect. Among the detection methods, non-invasive detection is more accepted by people, and it is also relatively simple and convenient. According to the current technology, one of the detection methods uses ultrasonic image capture and blood pressure measurement data to obtain blood vessel diameter, blood vessel Tissue thickness and related information to judge t...
