[0002] Pretreatment devices for stem cell storage are usually designed with ultraviolet sterilization. In order to improve work efficiency and consistency of operation, some pretreatment devices are integrated with automated control systems. Through ultraviolet irradiation for more than 30 minutes, sterilization can be automatically performed, reducing operator intervention and errors. At the same time, it can protect the safety of the vessels during transportation and movement of the device to prevent damage to the vessels.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 The utility model provides an embodiment: a pretreatment device for storing biological stem cells, comprising a bottom plate 1, a plurality of universal wheels are fixedly connected to the bottom of the bottom plate 1, and the device can be conveniently moved by the universal wheels. A storage box 2 is fixedly connected to the top of the bottom plate 1. The bottom plate 1 is a component that can carry the entire device and provide stability for the storage box 2. The interior of the storage box 2 is used to store stem cells and some components to prevent the stem cells and the internal structure from being damaged. The front end of the storage box 2 is rotatably connected to a box door 3.

The fixed block 4 is connected to the inside of the storage box 2 so that the motor 5 can be fixed by the fixed block 4, so that the motor 5 can work. The driving end of the motor 5 is fixedly connected with a disc 6, and the motor 5 can rotate by starting. The front end of the disc 6 is rotatably connected with a rotating rod 7. When the disc 6 rotates, the rotating rod 7 will move up and down. The bottom of the rotating rod 7 is rotatably connected with a moving rod 8. When the rotating rod 7 moves up and down, it will drive the moving rod 8 to realize a lifting motion trajectory. Both sides of the moving rod 8 are fixedly connected with sliders 9. When the moving rod 8 moves up and down, it will drive the sliders 9 to move together. Slide grooves 10 are opened inside the two sides of the storage box 2, and the outer side of the slider 9 is slidably connected to the inner side of the slide groove 10. When the slider 9 moves inside the slide groove 10, the movement trajectory of the moving rod 8 will be restricted, so that the moving rod 8 can only realize the movement trajectory of up and down lifting, so that it will not escape from the interior of the slide groove 10 and cause the moving rod 8 to deviate. The bottom of the moving rod 8 is fixedly connected with an ultraviolet lamp tube 27. When the moving rod 8 is lifted up and down, the ultraviolet lamp tube 27 will be driven to lift and lower at the same time.

The bottom end of the storage box 2 is fixedly connected with a stabilizing rod 11, and the outside of the stabilizing rod 11 is slidably connected with a tray 12. The tray 12 can slide slightly through the stabilizing rod 11. The outside of the stabilizing rod 11 is fixedly connected with a chassis 21. The stabilizing rod 11 can stabilize the fixed parts on the chassis 21 and also keep the chassis 21 balanced.

[0033] Reference Figure 3 - Figure 4The inside of the tray 12 is fixedly connected with a clamping assembly, and the clamping assembly includes a motor 2 13. The bottom of the motor 2 13 is fixedly connected to the inside of the tray 12. The driving end of the motor 2 13 is fixedly connected with a turntable 14. The turntable 14 can be rotated by the drive of the motor 2 13. Both sides of the turntable 14 are rotatably connected with rotating rods 15. When the turntable 14 rotates, the rotating rods 15 connected to both sides of the turntable 14 can be retracted. The far sides of the two rotating rods 15 are fixedly connected with sliding rods 16. The sliding rods 16 are moved inward by the contraction of the rotating rods 15. The top of the sliding rod 16 is fixedly connected with a connecting block 17. When the sliding rod 16 moves, the connecting block 17 is also driven to move. Sliding holes 19 are opened on both sides of the top of the tray 12. The sliding holes 19 are designed for the connection block 17 to be able to move. The outside of the connection block 17 is slidably connected to the inside of the sliding hole 19, and the connecting block 17 can be connected through the sliding hole 19. The movement of the connecting block 17 is restricted so that the connecting block 17 can realize a straight motion trajectory. The top of the connecting block 17 is fixedly connected with a clamping block 18. When the connecting block 17 moves, the clamping block 18 can also move. The adjacent ends of the two clamping blocks 18 are fixedly connected with a container 26. The clamping block 18 clamps and releases the container 26 by telescoping, so that the container 26 can maintain a stable effect and the container 26 can be conveniently taken. The bottom of the container 26 is in contact with the top of the tray 12. The container 26 can be placed on the surface of the tray 12 in a balanced manner through the tray 12 to facilitate clamping and taking. Sliding grooves 20 are provided at the front and rear ends of the tray 12. The front and rear sides of the slide bar 16 are slidably connected to the inside of the sliding groove 20.

[0034] The top of the chassis 21 is fixedly connected with a buffer assembly, which includes two blocks 22. The bottoms of the two blocks 22 are fixedly connected to the left and right sides of the chassis 21. The adjacent ends of the two blocks 22 are fixedly connected with dampers 23. The blocks 22 provide the dampers 23 with a fixed source. The outer sleeve of the dampers 23 is provided with a spring 24, which can help the dampers 23 share the buffering pressure. The adjacent ends of the two dampers 23 are rotatably connected with connecting rods 25. The top of the connecting rod 25 is rotatably connected to the bottom of the tray 12.

The other end of the spring 24 is fixedly connected to one side of the connecting rod 25, and the connecting rod 25 will transmit the buffering force to the spring 24.

[0035] Working principle: when the motor 15 is started, the disc 6 is rotated by the driving end of the motor 15. When the disc 6 rotates, the rotating rod 7 on the surface of the disc 6 is driven to rotate. When the rotating rod 7 rotates, the moving rod 8 is moved up and down, and the ultraviolet lamp 27 fixed at the bottom of the moving rod 8 can also move up and down to irradiate the vessel 26. The sliders 9 on both sides of the moving rod 8 can slide inside the slide groove 10 to move, and can be restricted to fall or rise vertically. When the motor 213 is started, the rotating disc 14 is rotated to pull the rotating rods 15 on both sides to make the slides The rod 16 can move inward, and the slide bar 16 can slide inside the slide groove 20, so that the movement of the slide bar 16 is linear. When the slide bar 16 moves, the connecting block 17 on the top moves inward, and the clamping block 18 on the top of the connecting block 17 is clamped inward by the influence of the connecting block 17 to clamp the container 26 to fix it. When the equipment is moving, the tray 12 will be shaken, and the shaking force will be transmitted to the damper 23 and the spring 24 through the connecting rod 25 at the bottom of the tray 12. When the spring 24 is subjected to force, it will deform and transmit the potential energy to the stopper 22 to achieve a buffering effect.
