摘要
在传统的人工心脏泵技术存在的问题上,如润滑、血栓的形成和溶血等,引进了磁悬浮技术,利用磁悬浮具有无接触、无摩擦和无润滑等优点来对血泵进行了新的研究。同时,采用AT89S51单片机作为控制器,输出三种波形(方波、正弦波、梯形波)作为心脏泵电机的驱动激励信号。人工心脏泵可满足生命医学工程领域中的相关实验要求。
Based on the existing problems of the traditional artificial heart pump technology, such as lubrication, thrombus formation and hemolytic issues, the magnetic levitation technology into the artificial heart pump,for its non- contact, no friction and without lubrication were introduced. At the some time, micro - controller unit （MCU） outputed three waveforms （square wave, sine wave, trapezoidal wave ） as drive excitation signal of motor. Changing drive excitation signal can change the speed of artificial beart pump, and can regulate and control the output of blood flow and pressure. The artificial heat pump can meet the requirement of experiments in medical engineering fields.
