Description

technical field [0001] The application belongs to the technical field of medical devices, and in particular relates to an in vitro test system and a test method for a heart valve. Background technique [0002] Heart valve disease is a common form of heart disease that is increasing in incidence as humans live longer and the population ages. Heart valve disease is irreversible and will only get worse gradually. Artificial heart valve replacement surgery is an effective way to treat severe heart valve disease. Whether it is a mechanical valve or a biological valve, strict in vitro testing, animal testing and clinical trials are required before clinical application. In vitro testing is an important part of the performance evaluation of artificial heart valves. The purpose is to obtain the performance parameters of the valve, evaluate the quality of the valve, and provide a basis for the performance optimization of the valve. Among them, the in vitro function test of artificia...
