Abstract

The invention provides a cardiac valve testing device, which comprises a liquid circulation supply and flow keeping mechanism, a liquid temperature keeping mechanism and a valve performance measurement mechanism, wherein the liquid circulation supply and flow keeping mechanism mainly comprises a liquid tank, a liquidometer, a flowmeter, a pump and a water tank; one side of the liquid tank is communicated with the valve performance measurement mechanism, and the other side of the liquid tank is communicated with the flowmeter; the lower end of the flowmeter is communicated with the pump; the lower end of the pump extends into the water tank through a pipeline; the water tank is full of blood simulation liquid; the liquid tank is connected with the liquidometer; the lower part of the liquidtank is communicated with the valve performance measurement mechanism; the liquid temperature keeping mechanism comprises a liquid tank heating device and a water tank heating device, wherein the liquid tank heating device and the water tank heating device are independently installed on the liquid tank and the water tank.

Description

technical field [0001] The invention relates to the technical field of artificial heart valves, in particular to the field of heart valve testing devices. Background technique [0002] At present, rheumatic heart disease is one of the common diseases in my country, especially in the south of my country, where the incidence rate is particularly high. The adult incidence rate is 2.98%. The heart valves of critically ill patients with this disease are usually so diseased that they cannot be repaired or corrected surgically. The only thing that works is an artificial heart valve replacement that saves lives. According to the regulations of GB12279-2008, artificial heart valves should undergo in vitro fluid dynamics tests, performance testing of various artificial heart valves, quality control of finished products, and improvement of valve type research, providing a basis for the formulation of quality inspection standards for artificial heart valves and the establishment of testi...
