TURBO BLOOD PUMP WITH INCLINED IMPELLER VANES

摘要

A blood pump used for extra corporeal circulation, and more particularly, a small turbo blood pump including a casing having a interior region, an aperture formed in an upper portion defining a blood outlet and an aperture formed in a lower portion defining a blood outlet. An impeller is rotatably mounted within said casing interior region and includes a rotary shaft and at least one vane depending therefrom. The at least one vane has an upper radius adjacent the blood inlet that is less than a lower radius adjacent the blood outlet. The base of the at least one vane forms an exterior angle of less than 90 DEG with the axis of the rotary shaft. A driven magnet is mounted to the at least one vane. The impeller is rotationally driven by a non-contacting driving magnet that is exterior to the casing.
