Abstract:: In order to realize the driving of pulsating blood pump, a novel electromagnetic driving device was put forward. Based on the simulated cardiopulmonary bypass experiment, the feasibility of the device was studied. The results of the study were as follows：The design process of the driving coil structure was scientific and reasonable, and the driving force met the requirements of the blood pump driving; The linear fitting equation of average perfusion pressure and driving current was 〖WTBX〗y=33.074x+6.6563, R2〖WTBZ〗=0.9784, which indicated that the driving device could output pulsatile flow according to the set pressure value to meet practical application needs. The drive efficiency of the device was 21.83%. The research shows that the new driving device designed in this paper has a great feasibility as a pulsating blood pump.
