Blood pump with turbine drive

摘要

A blood pump for use in CPB and other heart surgeries includes a sterilizable blood pump removably attached to a turbine drive unit. An impeller within the fully enclosed and sterile blood pump moves the blood from the pump inlet to the pump outlet. The pump snaps onto the turbine drive unit and a magnetic coupling between the pump and the drive unit is used to transmit the rotation of a turbine shaft to the pump impeller. The turbine drive unit is preferably a sterilizable unit which may be placed directly in the sterile surgical field. The blood pump with turbine drive allows the blood pump to be placed close to the surgical site and minimizes the length of the tubing required for connecting the pump to the patient.
