Aiming at the problem that the centrifugal machine in the prior art 202410730340.3 is poor in enrichment effect due to the fact that the centrifugal cup weight is increased to cause effective centrifugal force which cannot be achieved when a small centrifugal machine motor is used for enriching exosomes from blood sources, if the centrifugal machine with a larger motor is replaced, the occupied space of the whole exosome instrument is greatly increased, and the technical route of miniaturizing the exosome enrichment instrument is not consistent with that of the prior art, a new technical scheme for maintaining the centrifugal cup in a vertical state in the centrifuge tube taking and placing process on the premise that the centrifugal cup weight is not increased or is little increased is needed to be found urgently.
The invention adopts a lighter centrifugal cup, and the centrifugal cup has the technical characteristics of maintaining the vertical state, and other modes are basically the same as those of a 202410730340.3 centrifugal machine. Specifically, a thin-sheet magnetic structure is arranged at the bottom of each centrifugal cup, the plane of the bottom of the thin-sheet magnetic structure is perpendicular to the longitudinal axis of the centrifugal cup, a magnetic attraction structure is arranged at the bottom of the centrifugal machine, when a single centrifugal cup rotates to the position of the magnetic attraction structure, the attraction force of the magnetic attraction structure controls the thin-sheet structure to move close to the magnetic attraction structure, the magnetic attraction structure is arranged under the thin-sheet magnetic structure under the final stop state, the thin-sheet magnetic structure drives the centrifugal cup to maintain the vertical state, the thin-sheet magnetic structure can be ensured to attract the thin-sheet magnetic structure to the vertical state due to the arrangement, but because the magnetic structure is a thin-sheet structure, the weight image of the centrifugal cup is not large, and therefore, the smaller centrifugal machine can meet the requirement on centrifugal force when exosome is enriched.
