Heart valve test device

Abstract

The invention provides a heart valve test device. The heart valve test device is characterized by mainly comprising a liquid circular supply and pressure maintenance unit, a liquid temperature maintenance unit and a valve performance measurement unit, wherein the liquid circular supply and pressure maintenance unit comprises a liquid tank, a pump, a water channel and a liquid tank pressure gauge;the upper part of the liquid tank is communicated with the liquid tank pressure gauge; the lower part of the liquid tank is communicated with the pump; one end of the pump is communicated with a waterpipe which extends into the water channel; the water channel is internally filled with blood simulation liquid; the liquid temperature maintenance unit comprises a temperature control meter, a liquidtank heating device and a water channel heating device; the temperature control meter is connected with each of the liquid tank heating device and the water channel heating device; the temperature control meter is mounted at the bottom of the liquid tank and located at the opposite side of the valve performance measurement unit; and the liquid tank heating device and the water channel heating device are respectively mounted at the bottoms of the liquid tank and the water channel.

Description

technical field [0001] The present invention relates to the technical field of heart valves, in particular to the field of heart valve test devices. Background technique [0002] At present, rheumatic heart disease is one of the common diseases in my country, especially in southern my country, the incidence rate is particularly high, the adult incidence rate is 2.98%, the heart valve of the critically ill patients with this disease is usually too diseased to be repaired or corrected by surgery, The only thing that works is a replacement of a prosthetic heart valve to save lives. According to GB12279-2008, prosthetic heart valves are subject to in vitro hydrodynamic tests, performance testing of various prosthetic heart valves, quality control of finished products, and improvement of valve type research, providing the basis for the formulation of prosthetic heart valve quality inspection standards and the establishment of testing centers. a solid technical foundation.

AI Technical Summary

Problems solved by technology

The existing static test of artificial mechanical heart valves uses the traditional simple equipment, the device is unstable, the performance is unreliable, and the operation is 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. Require
