Abstract

The invention provides a method and a device for noninvasive quantitative assessment of cardiovascular characteristics based on combined acousto-optic spectroscopy. By means of acousto-optic combination, a photoelectric sensor and an ultrasonic detection sensor are placed along the heart and blood vessels to collect photoelectric signals and ultrasonic signals simultaneously, Based on multi-pointdifference, the group shift velocity and change rate of red blood cell population carrying hemoglobin were calculated, and the blood velocity distribution along the blood vessel was obtained. The spectral transfer function and ultrasonic spectral transfer function of any segment of blood vessel were quantitatively analyzed to form a combined acousto-optic spectrum, and the blood viscosity and blood vessel physical characteristics were further evaluated. In addition, the velocity and delay of the vibration wave transmitted to the blood vessels of the heart are measured to evaluate the tension and density of blood vessels and whether the blood vessels are unobstructed. This method is the concrete implementation and more comprehensive expansion of "pulse diagnosis" in traditional Chinese medicine, and can get the microscopic characteristics of blood and blood vessels without blood sampling and body analysis, and is also a useful complement to the non-invasive detection means in western medicine.

Description

technical field [0001] The present invention mainly relates to the technical field of photoelectricity and ultrasonic detection, and specifically relates to the combined use of acousto-optic methods to measure the movement speed and change rate of oxygenated red blood cells in human blood, as well as the spectral transfer function and ultrasonic spectral transfer function, so as to measure the tension density of blood vessels, blood vessel along the road A method and device for quantitative evaluation of the plugging performance of the Background technique [0002] The cardiovascular system is a closed tube system made up of the heart and blood vessels. The heart is the power organ, and the blood vessels are the pipes that transport blood. Through the rhythmic contraction and relaxation of the heart, blood is promoted to circulate continuously in a certain direction in the blood vessels. This is the blood circulation that we are familiar with. Blood circulation is mainly t...
