Artificial implanted mechanical heart valve bionic test simulation dynamic device

Abstract

The invention discloses anartificial implanted mechanical heart valve bionic test simulation dynamic device which comprises a base and a simulated thoracic cavity. The simulated thoracic cavity is installed on the base, and a rectangular groove is formed in the front side wall surface of the simulatedthoracic cavity. A heart simulation unit is disposed in the rectangular groove, a simulated circulation unit is disposed on the lower side of the heart simulation unit, and a dynamic detection unit is disposed on thesimulated circulation unit. The artificial implanted mechanical heart valve bionic test simulation dynamic device simulates a human thoracic cavitystructure by using bionic silica gel, and theheart simulation unit is arranged in the simulated thoracic cavity, and a mechanical heart active valve is placed in the heart simulation unit. Meanwhile, the simulated circulation unit is arranged in the simulated thoracic cavity, and bionic blood is injected into the heart simulation unit to realize the blood circulation simulation. The dynamic detection unit is arranged on the simulated circulation unit to dynamically detect various indexes of the mechanical heart valve, and thestructure is simple and the operation is convenient.

Description

technical field [0001] The invention relates to the technical field of artificial organ detection, in particular to a dynamic device for simulating a bionic test of an artificially implanted mechanical heart valve. Background technique [0002] The artificial mechanical valve is an artificial organ made of artificial materials that can be implanted in the heart to replace the heart valve (aortic valve, tricuspid valve, mitral valve), which can make blood flow in one direction and have the function of a natural heart valve. Disease is a heart disease with a high incidence in my country. Although the incidence of rheumatic heart disease is declining with the improvement of people's living environment, the incidence of valvular heart disease in the elderly is increasing year by year. There are about 200,000 cases of valve disease in my country every year. Disease patients need valve replacement, currently only nearly 10,000 artificial valves are used clinically every year.

Problems solved by technology

[0004] The purpose of the present invention is to solve the above problems, and design a kind of artificially implanted mechanical heart valve bionic test simulation dynamic equipment, which solves the problem that most of the existing artificial mechanical heart valves use static testing before leaving the factory, and traditional simple equipment and devices are used. The operation is not stable enough, the performance reliability is not high, and the operation is relatively complicated. At the same time, when simulating the flow and physiological conditions near the artificial heart valve, the control of various parameters cannot meet the requirements of accurate testing.
