摘　　要：该文设计一种新型的仿生左心室辅助血泵,其特点是采用液压驱动弹性隔膜结构,具有供血平稳、可靠,有利于防止血栓;可以利用流量传感器、压力传感器检测显示泵进、出口的血压和泵血量。该血泵可以根据人体心电R波实现与人体心率同步辅助或非同步辅助。设计目标是实现仿生搏动。动物实验中,血压波形逼近期望值,流量能够按照设定值稳定搏出,证明该泵能满足对心脏病人进行仿生左心室辅助的要求。This paper reports a novel design of bionic left ventricular auxiliary pump, and the characteristic is that elastic diaphragm of pump driven by hydraulic, having smooth, reliable blood supply, can prevent blood clots, can use the flow sensor, pressure sensor detection showing the blood pressure and blood volume at the inlet and outlet of the pump. The pump can go with heart rate synchronization or asynchronous auxiliary by the R wave of human body＇s ECG. The design goal is realization of bionic throb. Through the animal experiment, the blood pressure waveforms are close to expectations, stable flow can stroke according to the set value, which prove that the pump can meet the requirement for heart disease patients for bionic left ventricular assistant.
