Description
technical field [0001] The invention belongs to the technical field of biomedical engineering, and relates to an artificial heart assist device, in particular to a magnetic resistance suspension centrifugal device. Background technique [0002] The heart is the power source of human blood circulation. Cardiovascular diseases have become a hot spot in the medical field. Heart transplantation is an important way to treat critical heart disease patients. However, the demand for the heart far exceeds the supply, and artificial heart assist devices have emerged. . The first-generation artificial heart assist device uses mechanical or electromagnetic drive to generate periodic volume changes to simulate the beating of the heart. It has a large volume, complex structure, and short life; the second-generation artificial heart assist device uses mechanical bearings to support the high-speed rotating impeller. Due to friction, blood wear, heat generation, induced hemolysis, thrombus ...
