摘　　要：临床应用中 ,对人工心脏的输出流量进行及时、精确的检测十分必要 ,但实现起来却比较困难。针对江苏理工大学生物医学工程研究所研制的叶轮式人工心脏 ,提出采用驱动电机参数 (功率和转速 )间接测量血泵输出流量的方法 ,从而避免引入传感器探针 ,降低测量装置的复杂性 ,减小感染机会。实验结果表明 :这种测量方法能够达到一定精度 ,具有进一步研究价值。It is important, but difficult to measure pump flow accurately in clinical application. The authors put forward a noninvasive pump flow estimation method, based on motor input power and rotary speed of an impeller artificial heart, developed by Inst. Biomed. Eng. Jiangsu Univ. of Sci. and Tech. Because there is no need to use any sensor, the device becomes simple and the chance of patient being infected is less. Test results showed that the method could solve the problem successfully, and it is worth to investigating further.
