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
