    摘要： A blood pump used for extra corporeal circulation, and more particularly, as a small turbo blood pump including a casing having an interior region, an aperture formed in an upper portion defining a blood inlet, 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 extends radially less near the blood inlet than near the blood outlet. The base of the at least one vane forms an exterior angle of less 90° 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.

    摘要： A turbo blood pump includes a housing 1, an impeller 5 rotatably disposed in a pumping chamber 2, bearings 9 and 10 for rotatably supporting the impeller, a rotor 13 provided outside the housing and rotationally driven by a motor, driven magnets 12 mounted on the impeller, and driving magnets 16 mounted on the rotor. The driven magnets and the driving magnets face each other via a wall of the housing to form magnetic coupling. The driven magnets and the driving magnets are arranged so that a direction of the magnetic coupling inclines with respect to a rotation axis of the impeller. The pump ensures sufficiently strong magnetic coupling between an impeller and a rotor and effects reduced load on a lower bearing supporting the impeller and little risk of hemolysis and blood stagnation.

    摘要： A turbo blood pump includes a housing 1 having a pump chamber 2, an inlet port 3, and an outlet port 4, an impeller 5 disposed rotatably in the pump chamber, an upper bearing 9 and a lower bearing 10 supporting the impeller rotatably, and a driving force transmitting unit for driving the impeller to rotate. The upper bearing is supported at a position in the pump chamber below the inlet port, so that a cross-sectional area of the pump chamber in a plane including an upper end of the upper bearing and being orthogonal to a shaft of the impeller is larger than a cross-sectional area of a flow path of the inlet port at a portion where the inlet port is coupled to the pump chamber, and thus obstruction with respect to blood flow by the upper bearing is of such a degree as to be permissible from a practical viewpoint, while an impeller is supported by upper and lower bearings. Thereby, the pump is less likely to cause problems of blood stagnation and thrombus formation.
