Non-contact driven magnetic levitation nutation blood pump

The invention relates to a non-contact driven magnetic levitation nutation blood pump. The pump includes a shell with a fluid containing cavity and a nutation mechanism; the nutation mechanism dividesthe fluid containing cavity into a first chamber and a second chamber, the nutation mechanism includes a nutation disk, a magnetic suspension member and a driving member, and the nutation disk swingsrelative to the fluid containing cavity to change the size of the first chamber and the second chamber; the magnetic suspension member includes two hemispherical shell magnets on the upper and lowersides of the nutation disk, inner magnetic components embedded in the two hemispherical shell magnets, and outer magnetic components, and the magnetic properties of the outer magnetic components are opposite to those of the inner magnetic components; and the driving member includes a rotating component, a plurality of sector-shaped magnet blocks and a pair of magnets, the rotating component is rotatably supported on the she
