Abstract:
ABSTRACT The invention relates to a non-contact driving magnetic levitation nutation blood pump, which comprises a shell with a fluid chamber and a nutation mechanism. The nutation mechanism divides the fluid chamber into a first chamber and a second chamber, and comprises a nutation disk, a magnetic levitation component and a driving component.The nutation disk swings relative to the fluid chamber to change the sizes of the first chamber and the second chamber.The magnetic levitation component comprises two hemispherical shell magnets on the upper and lower sides of the nutation disk, inner magnet assemblies embedded in the two hemispherical shell magnets respectively, and outer magnet assemblies.The magnetism of the outer magnet assemblies is opposite to that of the inner magnet assemblies. The driving component includes a rotating assembly rotatably supported on a shell, a plurality of sector magnet blocks arranged at the outer peripheral end of the nutation disk, and a magnet pair including two magnets opposed in the circumferential direction. The two magnets can attract the sector magnet blocks when the rotating assembly rotates, so that the outer peripheral end of the suspended nutation disk swings up or down in sequence along the circumferential direction. 1/3 10 20 -30 -- 40 8 O 50 - 100 90 50 40 30 60 70 Figure 1
