[0002] Medical examination is the examination of microbiology, immunology, biochemistry, genetics, hematology, biophysics, cytology and other aspects to materials taken from the human body, thereby providing information for preventing, diagnosing, treating human diseases and assessing human health. The indispensable equipment in the process of medical examination is centrifuge.

[0003] For example, the publication number CN208340968U discloses a centrifugal equipment for medical examination. The contrast patent can effectively protect the test tube and prevent the test tube from being cracked during the centrifugal process by installing the fixing frame device.

[0004] However, the applicant finds that the distance between all the holes on the fixing frame device and the axis of the rotating shaft is equal, so that the centrifugal force received by the reagent tube inserted in the hole is the same when the rotating shaft rotates at a certain speed. Different substances to be tested require different centrifugal forces, which leads to the fact that only one kind of substance to be tested can be centrifuged at a time, and multiple substances to be tested cannot be centrifuged at a time. In addition, the sleeve of the patent can only accommodate reagent tubes of a certain length. If short blood collection tubes need to be placed, an adapter needs to be placed in the sleeve first, and then the short blood collection tube needs to be placed. The process is complicated, and the adapter is not easy to remove after the subsequent centrifugation is completed, which reduces the centrifugation efficiency. UTILITY MODEL CONTENT

[0007] The inner slots and the outer slots are formed in the rotating disc, the distance between the axis of the rotating disc and the inner slots is different from the distance between the axis of the rotating disc and the outer slots, so that the centrifugal force received by the reagent tube inserted in the inner slots is different from the centrifugal force received by the reagent tube inserted in the outer slots during the rotation of the rotating disc.

[0008] The sleeve assembly comprises a plug plate matched with the outer insertion slot and the inner insertion slot, the end of the plug plate is fixedly connected with a sleeve through a ring, the top of the sleeve is fixedly connected with a ring, and a placing cylinder for receiving the bottom of the reagent tube is slidably arranged in the sleeve; when the reagent tube is inserted into the ring and extends into the sleeve, the position of the placing cylinder can be adjusted so that the placing cylinder can receive reagent tubes of different lengths.

[0009] Preferably, the plurality of outer insertion slots and inner insertion slots are uniformly distributed on the rotating disc in a circle, and the distance between the inner insertion slot and the axis of the rotating disc is less than the distance between the outer insertion slot and the axis of the rotating disc.

[0010] Preferably, each inner insertion slot is located between two adjacent outer insertion slots, and a slot is further formed between the two adjacent outer insertion slots.

[0029] The sleeve assembly 6 comprises a plug plate 61 matched with the outer slots 51 and the inner slots 52, the end of the plug plate 61 is fixedly connected with a sleeve 62 through a ring, the top of the sleeve 62 is fixedly connected with a ring 63, and a placing cylinder 64 for accommodating the bottom of a reagent tube is slidably arranged in the sleeve 62, when the reagent tube is inserted into the ring 63 and into the sleeve 62, the position of the placing cylinder 64 can be adjusted, so that the placing cylinder 64 can accommodate reagent tubes of different lengths.

[0030] Through the arrangement of the plug plate 61, the inner slots 52 and the outer slots 51, when the reagent tube needs to be centrifuged, the sleeve 62 can be quickly inserted into the outer slots 51 or the inner slots 52 through the plug plate 61, and then the reagent tube can be placed into the sleeve 62, and after being used for a period of time, the sleeve 62 can be quickly taken out for cleaning or replacement.

[0031] The centrifugal force received by the sleeve assembly 6 inserted into the inner slots 52 is different from the centrifugal force received by the sleeve assembly 6 inserted into the outer slots 51, so that the sleeve assembly 6 and the reagent tube can be inserted into the outer slots 51 or the inner slots 52 according to the centrifugal force required by the material to be inspected, and a plurality of materials to be inspected can be centrifuged at one time;
