Abstract

The invention discloses a ventricular assist device performance test system, which comprises a heart blood circulation simulation system, a ventricular assist flow path system, a data acquisition system, an upper computer and a control system, the backflow chamber is communicated with the heart simulation assembly through an incoming flow pipeline and a backflow pipeline, the backflow chamber is filled with a blood simulation medium, and the heart simulation assembly can beat to enable the blood simulation medium to flow into the heart simulation assembly from the backflow chamber through the incoming flow pipeline and flow back into the backflow chamber through the backflow pipeline; the ventricular auxiliary flow path system is provided with a ventricular auxiliary device, the ventricular auxiliary device is communicated with the heart simulation assembly through an auxiliary inflow pipeline, and the ventricular auxiliary device is communicated with the backflow pipeline through an auxiliary outflow pipeline. The ventricular assist device performance test system completely simulates a loop of a blood circulation system in a heart, and various performance tests are carried out on the ventricular assist device.

Description

technical field [0001] The invention relates to the technical field of medical device testing, in particular to a performance testing system for a ventricular assist device. Background technique [0002] Heart failure is the only type of cardiovascular disease that continues to rise in the world. The current treatment methods are mainly medical treatment and surgical treatment. Medical treatment can only relieve symptoms, and it is difficult to prolong the patient's life. Surgical treatment methods are mainly divided into heart transplantation and artificial heart implantation. However, due to the shortage of donors, more than 5,000 heart transplants are performed every year around the world, which is in short supply. Ventricular assist devices represent the "mainstream direction" in the development of artificial hearts, and their clinical application has been standardized. With the continuous improvement of medical management, patient selection and technology, the scope ...
