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, comprising:

a housing (1) having a pump chamber (2), an inlet port (3), and an outlet port (4); an impeller (5) comprising a shaft (7) and being disposed rotatably in the pump chamber; upper and lower bearings (9,10) supporting the impeller shaft (7) rotatably; and a driving force transmitting unit (12) for driving the impeller to rotate, wherein the upper bearing is supported at a position in the pump chamber below the inlet port by a plurality of bearing supports (17) fixed at a first end to a lower end of the inlet port (3) and extended toward the pump chamber to support the upper bearing by a second and thereof, the shaft (7) of the impeller has a small diameter portion at an upper end which has a diameter smaller than that of a large diameter portion of the lower part of the shaft, the upper bearing (9) has a bore at a lower end, the small diameter portion being inserted into the bore of the upper bearing so that the upper portion of the shaft (7) is supported by the upper bearing, the lower bearing (10) has a bore at an upper end, the lower end portion of the shaft being inserted into the bore of the lower bearing so that the lower portion of the shaft (7) is supported by the lower bearing, and the shaft has a slant surface formed by varying the diameter gradually at the boundary between the small diameter portion and the large diameter portion, the slant surface of the shaft facing in the end surface around the bore.

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.
