摘　　要：应用自制隔膜泵、非搏动流叶轮泵和搏动流叶轮泵，以及临床用的美国Sarns转子泵分别在迷你猪和小公牛身上做左心室或双心室辅助试验，结果显示搏动流泵在自然心脏衰竭时能维持动物主动脉压的搏动特性，从而降低周身循环阻力而增加血液循环流量，而叶轮泵及转子泵因没有解膜返流能提高动物主动脉舒张压，增加自然心脏冠状动脉灌注，因此搏动流叶轮泵对于衰竭心脏功能的恢复，最为有利。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.

关 键 词：心室辅助泵 血液循环流量 冠状动脉灌注
