Mechanical cardiac valve simulating detection device

Abstract

The invention discloses a mechanical cardiac valve simulating detection device. The mechanical cardiac valve simulating detection device comprises a driving valve, a simulated heart and an accommodating frame, wherein the driving valve is mounted on the simulated heart; the simulated heart is arranged on the accommodating frame; a pair of valve detecting units adopting the same structure is arranged on two sides of the driving valve in the simulated heart; and a blood circulation unit is arranged on the simulated heart. The mechanical cardiac valve simulating detection device disclosed by the invention has the beneficial effects that the mechanical cardiac valve simulating detection device is convenient to observe and ingenious in structure; the simulated heart cooperates with the blood circulation unit to perform blood circulation simulation; the simulated heart cooperates with the valve detecting units to perform fatigue-resistant and pressure-resistant characteristic detection of the valves; through a fixing structure arranged on the mechanical cardiac valve simulating detection device, quick replacing of the valve is performed, so that the operation of experimenters is convenient; and through the cooperation of the above structures, the switching characteristic and the compression resistant characteristic of the valve can be quickly and effectively detected.

Description

technical field [0001] The invention relates to the technical field of heart valve simulation detection, in particular to a mechanical heart valve simulation detection device. Background technique [0002] A valve is a membrane-like structure that can open and close in the organs of humans or some animals. This article only describes the valves in the human heart. Every human heart has four valves. The aortic valve connects the left ventricle to the aorta, the pulmonary valve connects the right ventricle to the pulmonary artery, the mitral valve connects the left atrium to the left ventricle, and the tricuspid valve connects the right atrium to the right ventricle. They all act as one-way valves, so that blood can only flow from one direction to the other and not back. [0003] Artificial mechanical valve is an artificial organ made of artificial materials that can be implanted in the heart to replace heart valves (aortic valve, tricuspid valve, and mitral valve), which c...

Problems solved by technology

[0005] The purpose of the present invention is to solve the above problems, and design a mechanical heart valve simulation detection device, which solves the problem that the existing active valve detection devices usually use static detection, which only detects a characteristic of the valve, and cannot be accurate at the same time. To test the switch characteristics and compression characteristics of the valve, and the structure is complex, the cost is high, and the detection process is relatively cumbersome, and it is very dependent on people's operation and detection, which takes up a lot of time for the experimenters.
