[0024] The technical scheme in the embodiment of the application effectively solves the technical problems that the reagent kit used for mesenchymal stem cell separation and expansion at present has poor mixing effect, the reagent placed in the reagent kit is prone to precipitate, and the mesenchymal stem cells cannot be well contacted with the additive, and the separation and expansion are slow, and the overall idea is as follows:

[0025] For example, Figures 1 to 4The utility model provides a mesenchymal stem cell separation amplification kit, which solves the problems in the prior art, and comprises a kit 1, a cover plate 101 is arranged on the top of the kit 1, a driving part 21 is arranged on the inner bottom of the kit 1, a rectangular block 22 is fixedly connected to the top end of the driving part 21, driving assemblies 23 are arranged on the four sides of the rectangular block 22, a ring plate 102 is fixedly connected to the inner side of the kit 1 close to the bottom end, a plurality of extrusion blocks 43 are fixedly connected to the inner side of the kit 1, the driving part 21 comprises a speed reducer 211, the speed reducer 211 is fixedly installed on the inner bottom of the kit 1, a main gear 212 is fixedly connected to the output end of the speed reducer 211, and a slave gear 213 is meshedly connected to one side of the main gear 212.

[0026] By adopting the above technical scheme, the speed reducer 211 drives the slave gear 213 to rotate through the main gear 212, the slave gear 213 drives the rotating shaft 214 to rotate, the rotating shaft 214 drives the four connecting rods 231 of the rectangular block 22 to rotate, and the reagent tube 3 and the test tube sleeve 237 rotate around the rotating shaft 214 as the center.

[0027] Specifically, the rotating shaft 214 is fixedly connected to the middle part of the slave gear 213, the bottom end of the rotating shaft 214 is rotationally connected to the kit 1, and the top end of the rotating shaft 214 is welded to the rectangular block 22; the driving assembly 23 comprises a connecting rod 231, the connecting rod 231 is fixedly connected to the four sides of the rectangular block 22, a hollow rod 233 is arranged on one side of the connecting rod 231, one end of the hollow rod 233 is fixedly connected to a rectangular frame 236, the test tube sleeve 237 is arranged in the rectangular frame 236, the reagent tube 3 is arranged in the test tube sleeve 237, the extrusion plate 238 is arranged in the middle part of the test tube sleeve 237, the spring 239 is fixedly connected between the extrusion plate 238 and the rectangular frame 236, a plurality of mounting blocks 4 are fixedly connected to the top of the ring plate 102, the ball 41 is arranged on the top end of the mounting block 4, the rectangular rod 232 is fixedly connected to one side of the connecting rod 231, the rectangular groove 234 corresponding to the rectangular rod 232 is formed in one side of the hollow rod 233, and the spring 235 is fixedly connected between the connecting rod 231 and the hollow rod 233.

[0028] By adopting the above technical solution, during the rotation, the collision block 230 will collide with the squeezing block 43 inside the reagent kit 1. The force generated by the collision will drive the hollow rod 233 to compress the spring 235. When the collision force disappears, the spring 235 will return to its original state. Under the action of the spring 235's restoring force, the cell tissue fluid inside the reagent tube 3 will vibrate, thereby preventing the cell tissue fluid inside the reagent tube 3 from precipitating. At the same time, as the test tube sleeve 237 rotates, its bottom end will collide with the ball bearing 41 above the mounting block 4. Under the action of this collision force, the test tube sleeve 237 can move upward and stretch the spring 239. When this force disappears, the spring 239 will return to its original state.

The driven gear 213 drives the rotating shaft 214 to rotate, and the rotating shaft 214 drives the four connecting rods 231 of the rectangular block 22 to rotate. The reagent tube 3 and the test tube sleeve 237 rotate around the rotating shaft 214. During the rotation, the collision block 230 collides with the squeezing block 43 inside the reagent kit 1. The force generated by the collision drives the hollow rod 233 to compress the spring 235. When the collision force disappears, the spring 235 returns to its original state. Under the action of the spring 235's restoring force, the... The cell tissue fluid inside reagent tube 3 vibrates, thus preventing the cell tissue fluid inside reagent tube 3 from settling. At the same time, as the test tube sleeve 237 rotates, its bottom end collides with the ball bearing 41 above the mounting block 4. Under the action of this collision force, the test tube sleeve 237 moves upward and stretches the spring 239. When the force disappears, the spring 239 returns to its original position. Under the action of the restoring force of the spring 239, the squeezing plate 238 and the test tube sleeve 237 can be driven to move downward quickly, thus preventing the cell tissue fluid inside reagent tube 3 from settling.
