Abstract:
This paper built the mathematical model of a centrifugal blood pump, which was designed by ourselves, combined it with that of the human cardiovascular system and simulated the coupling system using Matlab. Then we set up the experiment platform, linked the blood pump to mock human cardiovascular system in case of three-stage heart failure, and measured aortic pressure and flow under different speed. The comparison between experiment results and simulation results not only indicates the coupling model is correct and the blood pump works wel , but also shows that with the increase of blood pump speed, the pulsation of aortic pressure and flow wil be reduced, this situation wil affect the structure and function of blood vessels.
