CENTRIFUGAL BLOOD PUMP DRIVER APPARATUS AND METHOD

摘要

An intelligent centrifugal blood pump driver (300) comprises a motor housing (302) and the housing contains a motor (306) for rotationally driving the centrifugal blood pump (304) and a controller (308) operatively associated with the motor for controlling the rotational speed of the motor (306); a speed selector (404) for generating a selected speed signal (405) signifying a selected rotational speed for the motor (306); sensors (310) operatively associated with the motor or controller for sensing the rotational speed of the motor (306) and outputting a monitor signal (312) signifying such rotational speed; program memory (305) for storage of a program of microprocessor readable instructions; a microprocessor (314, 408) under program control, in electrical connection with the controller (308), the speed selector (404), the sensor (310) and the program memory (305, 406), for receiving the selected speed signal (405) and generating a speed control signal (316) to the controller (308) signifying the selected speed for the controller (308), and for receiving the monitor signal and outputting a display signal (318 and 418); a display (320, 420) in electrical communication with the microprocessor (314, 408) and responsive to the display signal (318, 418) for displaying information.
