<p>A blood pump used for extra corporeal circulation, and more particularly, a small turbo blood pump including a casing (3) having an interior region, an aperture formed in an upper portion defining a blood inlet (1), and an aperture formed in a lower portion defining a blood outlet (2). An impeller is rotatably mounted within said casing interior region and includes a rotary shaft (12) and at least one vane depending therefrom. The at least one vane has an upper radius adjacent the blood inlet (1) that is less than a lower radius adjacent the blood outlet (12). The base of the at least one vane forms an exterior angle of less than 90° with the axis of the rotary shaft (12). A driven magnet (15) 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 (3).</p> |
