人工心脏电动叶轮血泵动物试验及临床试用

研制的叶轮血泵在动物小公牛身上做左心室辅助存活试验，其中三头牛存活约２个月，血液生化检测表明，动物血液成分及器官功能均未有显著改变。

The Animal Experiments and Clinical Trial of Impeller Pump Used as Left Ventricular or Biventricular Assist Device

The authors' impeller pump as a left ventricular or biventricular assist device was evaluated in animal experiments and clinical trial. Three calves survived over 6 weeks in left ventricular assist experiments and neither blood damage nor organ dysfunction of the animals was detected. In clinical trial, the pump supported both the greater and lesser circulation of a 6-year-old child with trilogy of Fallot and low output syndrome after open heart surgery. In 43 hours the pump worked properly. The pump weighing 240 g can perform either in pulsatile or in nonpulsatile mode. In pulsatile pumping, the impeller changes its rotating speed periodically by introducing a square wave form voltage into the motor coil.
