摘要： A turbo blood pump includes a housing, an impeller rotatably disposed in a pumping chamber, bearings for rotatably supporting the impeller, a rotor provided outside the housing and rotationally driven by a motor, driven magnets mounted on the impeller, and driving magnets 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.
