ABSTRACT:
A centrifugal blood pump, used for heart-lung machines or the like, comprises an impeller, a casing having a suction inlet and a delivery outlet and being equipped with a space for rotatably accommodating the impeller, and a magnetic drive means disposed outside the casing. The impeller is of a rotationally symmetric shape and has a rotary vane section and a cylindrical section equipped with a magnet means. The magnet drive means for generating a rotating magnetic field coaxially encloses the magnet means of the above-mentioned cylindrical section and rotates the impeller in cooperation with the magnet means. At least the end section of the impeller's rotation center on the rotary vane section side is supported preferably by a pivot bearing. The pivot and the bearing thereof are preferably made of ceramics.
