摘要： A disposable centrifugal blood pump with magnetic coupling provides a centrifugal blood pump with magnetic coupling which is simple in structure of disposable parts with low cost. Therefore, a housing as the disposable part includes a rotor having pole faces extending on the outer-peripheral surface and projecting inward from the inner-peripheral surface and an impeller attached to the rotor, and a stator as a reusable part includes three or more electromagnets for electromagnetic coupling for forming a magnetic coupling between the stator and the rotor, a torque transmission disk formed by sandwiching a ring-shaped permanent magnet between two upper and lower ring members and having pole faces corresponding to the pole faces projecting from the inner-peripheral surface of the rotor formed to project for generating a magnetic coupling between stator and rotor, a motor for rotating the torque transmission disk, and a displacement gauge for measuring displacement of the rotor.

摘要： A magnetically-levitated centrifugal pump, in which permanent magnets are not used for disposable sections, is provided with a pump head section and a pump section. The pump section comprises a stator, a torque transmission disc, a motor, a displacement sensor, and a pump housing. The stator has longer depth than protrusion length of a rotor accommodation section in which permanent magnets are not used, is equipped with a rotor insertion section, in which the rotor accommodation section is disposed so as to be able to be inserted and removed, on the side of one end section, and disposes three or more than three electromagnets for magnetic bearings, which magnetically couple with the rotor, at equal intervals. The torque transmission disc, which is disposed inside the rotor insertion section and which magnetically couples with the rotor, is formed by bonding ring components, which are made from magnetic material and are provided with protrusions at positions opposite protrusions on the rotor, between plural ring-shaped permanent magnets, which are magnetized in the thickness direction thereof, such that like-poles face each other, and then by placing another ring component on top of the uppermost ring-shaped permanent magnet. The motor rotationally drives the torque transmission disc. The displacement sensor measures radial displacement of the rotor.
