Abstract :
In this paper, a bionic artificial heart blood pump driven by permanent magnet is proposed. This permanent magnet driving device of the blood pump can solve the problems of the blood pump power supply from the body´s external to the internal and the heat generated by the energy conversion components inside the body. In addition, the blood pump can overcome some shortcomings of the existing pneumatic or electric diaphragm blood pump, for example, the short life of the pump is caused by the fact that the blood bag made of flexible material is periodically pressured and repeatedly folded.
