Test system and test method for simulating heart valve model in in-vivo flow environment

Abstract

The invention provides a test system and a test method for simulating a heart valve model in an in-vivo flow environment. The test system comprises a fluid circulation system, a valve supporting system, a fluid monitoring system, an imaging system and a control system, wherein the valve supporting system comprises a valve support and a stepping rotating motor, and the valve support is fixed to the rotor; the fluid monitoring system is used for monitoring various data of fluid in real time; the imaging system is used for monitoring position information of the valve model in the fluid; the control system comprises a driver, a controller and a central processing system, the driver is connected with the stepping motor and the controller and is responsible for receiving instructions transmitted by the controller and driving the stepping motor to rotate, and the controller is connected with the driver and the central processing system, and is responsible for receiving the feedback information of the stepping motor and receiving a program instruction of the central processing system to form a closed-loop control system. According to the test system, hydrodynamic changes of the heart valve in different flowing environments can be simulated, and a powerful basis is provided for early diagnosis, intervention and treatment of heart valve diseases.

Description

technical field [0001] The invention belongs to the field of medical devices, and relates to a test system and a test method for a heart valve model in a simulated internal flow environment. Background technique [0002] In my country, cardiovascular diseases are the primary cause of threats to human health. Affected by fierce competition and poor living environment in today's society, the incidence of the disease is becoming younger and the incidence rate is increasing year by year. The heart valve, as a biological valve that ensures the heart promotes the directional flow of blood circulation, has an important impact on the health of the heart. Heart valve disease will affect the normal blood circulation of the human body, and even endanger life. At present, the causes of valvular heart disease include congenital structural abnormalities, rheumatism, infection, etc. These factors will cause valve stenosis or insufficiency in varying degrees, which will lead to changes in...
