ABSTRACT:
A centrifugal clinical blood pump comprises a bell-shape or conical housing with a suction inlet at the apex and a tangential outlet adjacent the base. A conical rotator comprising at least one downwardly outflaring skirt surrounding a central cone is rotatably mounted in the housing by a jewelled pivot at the center of the base and a jewelled pivot mounted in the apex of the housing by a spider which is streamlined to permit free flow of fluid through the inlet into the pump housing. The jewelled pivots comprise a pointed shaft received in a recess of a jewel bearing or a single ball between two recessed jewel bearings. The rotator is driven by spaced permanent magnets embedded in the base of the rotator and an externally generated rotating magnetic field.
