Problems solved by technology

[0003] At present, domestic and foreign scholars focus on the study of heart valve stents, but there are few studies on related test devices, and most of them are tested for a single performance, and the scope of application is relatively narrow, for example, it is only suitable for testing Transvalvular pressure gradient of mechanical valves, or durability of balloon valve stents or valve orifice area
These factors will limit the technical development of valves

Abstract

The invention provides a valve stent performance testing device. The testing device comprises a multifunctional test board, a liquid storage tank, a single-chip microcomputer and a computer, the multifunctional test board comprises a first test board I and a second test board II, the first test board I can test the strain, vibration frequency, transvalvular differential pressure and opening area of a valve stent, and the second test board II can test the durability testing the valve stent. The first test board I and the second test board II are used for testing at the same time, dynamic testing of multiple performances of the artificial valve stent can be achieved at the same time, independent testing can also be achieved, and use is convenient and flexible. The defect that one detection device can only test one performance in a previous test method is overcome, the application range is wide, and the universal adaptability is achieved.

Description

technical field [0001] The invention belongs to the technical field of medical device performance testing, and in particular relates to a valve support performance testing device. Background technique [0002] At present, patients with heart valve disease in my country account for about 30% of heart disease patients, and a large number of patients need heart valve replacement surgery every year. Artificial heart valve, as a cardiac implant interventional medical device for the treatment of heart valve diseases or defects, was first used clinically in 1960, and has now become a very important medical device in the field of cardiovascular treatment. After that, it went through the stages of mechanical valve, biological tissue valve, and interventional valve. Although many heart valve stents have achieved very good results, there is still a big gap compared with native heart valves. All prosthetic valves are hemodynamically abnormal compared to normal natural valves. Therefo...
