[Research on the control arithmetic for blood pump based on ventricular work].
The control arithmetic is proposed for axial blood pump driven by extracorporeal alternating magnet field based on ventricular work. According to health physiological parameters, the control model is verified by calculation and experiment. The control model used for driving blood pump is derived from the relationship of natural heart and artificial heart. By comparison with others, the control arithmetic based on ventricular work is more helpful in appraising the property of left ventricular aided device (LVAD), in meeting human body's natural need, and in effective use of motor for avoiding motor running at high speed and hence preventing the blood from the destruction caused by a blood pump at high temperature.
