With the authors' diaphragm pump and pulsatile as well as nonpulastile impeller pumps, and the clinically used Sarns Roller, both left ventricular assist and biventricular assist experiments were performed on mini pigs and calves. The results demonstrate that the pulsatile impeller pump is the best assist pump for recovering the heart function, because it maintains the pulsatility of aortic pressure by heart failure and thus increases the circulation volume, and it enlarges the diastolic pressure so as to increase the perfusion in coronary artery because it has no backflow.
使用作者的隔膜泵、搏动性及非搏动性叶轮泵，以及临床使用的Sarns滚压泵，在小型猪和小牛身上进行了左心室辅助和双心室辅助实验。结果表明，搏动性叶轮泵是恢复心脏功能的最佳辅助泵，因为它通过心力衰竭维持主动脉压力的搏动性，从而增加循环血量，并且由于它没有回流，所以能增大舒张压以增加冠状动脉灌注。
