Description

Technical Field

[0001] This utility model relates to the field of hematopoietic stem cell storage technology, specifically a hematopoietic stem cell blood bag cryopreservation box. Background Technology

[0002] Hematopoietic stem cells can save many people suffering from blood diseases, the most common being leukemia. After a donor donates stem cells, they need to be quickly transported to the patient's location, which requires the use of cryopreservation boxes.

[0003] A search revealed a utility model patent in China with patent publication number CN214509057U, which discloses a cryopreservation box for hematopoietic stem cell blood bags. The box generally includes a body with partitions fixedly installed inside. A vertical plate is fixedly installed between the middle of the upper surface of the partitions and the top surface of the body. In use, by moving the positions of multiple movable plates, multiple partitions move to separate and place multiple hematopoietic stem cell blood bags, achieving the effect of separating multiple blood bags and preventing them from freezing together and becoming difficult to remove. The vertical plate separates two drawers for easy access. When transporting hematopoietic stem cell blood bags, the release of large amounts of nitrogen gas is avoided, thus conserving nitrogen resources. However, the above-mentioned device still has certain shortcomings. For example, the number of moving plates is fixed, but the number of blood bags varies under different circumstances, resulting in idle moving plates. The device does not limit the movement of the moving plates, and the equipment inevitably shakes during the transport of blood bags. During this process, the blood bags impact the moving plates, and the unrestricted moving plates will move, causing continuous collisions between the blood bags and the moving plates, which is not conducive to the transport of blood bags. Therefore, we propose a hematopoietic stem cell blood bag cryopreservation box. Utility Model Content

The fixing frame 7 is used to limit and press down the multiple fixing boxes 3. The latch lock 8 is used to quickly connect the fixing frame 7 for convenient use.

[0031] An opening is formed on box body 1;

[0032] The liquid nitrogen box 11 is fixedly connected inside the box body 1. One end of the liquid nitrogen box 11 is located in the opening. The liquid nitrogen box 11 has a liquid inlet, and a sealing cap 12 is threadedly connected to the liquid inlet. A fixing plate 13 is provided on the liquid nitrogen box 11.

The liquid inlet is used to facilitate the addition of liquid nitrogen, the sealing cap 12 is used for sealing, and the vent holes 14 are used for the flow of nitrogen.

[0033] The limiting mechanism includes a groove and a limiting slot. The groove is formed on the cover plate 5, and the limiting slot is formed on the fixed box 3. Two sliding grooves are formed in the groove. A slider 15 is slidably connected in the sliding groove. A spring 16 is provided between the slider 15 and the sliding groove. A limiting plate 17 is fixedly connected between the two sliders 15. One end of the limiting plate 17 is located in the limiting slot. The limiting plate 17 is used to be locked in the limiting slot. The spring 16 is used to provide elastic force. The slider 15 is used to slide the limiting plate 17. In this way, the cover plate 5 can be limited and fixed.

[0034] A connecting block 18 is fixedly connected to the limiting plate 17, and a pull ring 19 is rotatably connected to the connecting block 18 to facilitate moving the limiting plate 17 and thus opening the cover plate 5.

[0037] In summary, the working principle and process of this hematopoietic stem cell cryopreservation box are as follows: First, place the hematopoietic stem cell cryopreservation box at the desired location. Then, when using it, rotate the lower sealing cap 12 to add liquid nitrogen into the liquid nitrogen box 11 through the inlet. The liquid nitrogen diffuses and flows into the box body 1 through the vent 14. Open the latch lock 8 and rotate the fixing frame 7. At this time, the fixing box 3 can be pulled out by the handle 1 4. The fixing box 3 drives the two sliders 21 to move. Then, use the pull ring 19 to pull down the limiting plate 17. The limiting plate 17 moves... The slider 15 moves, compressing the spring 16. The limiting plate 17 moves out of the limiting groove. At this time, people can pull the cover plate 5 through the pull ring 19. After rotating the lower cover plate 5, the blood bag is placed in the fixing box 3, and then the cover plate 5 is installed. At this time, the protective pad 10 will clamp and protect the blood bag. Then, the fixing box 3 is put back into the box body 1 through the handle 4. This completes the placement of the blood bag, avoiding shaking and collision of the blood bag. At the same time, it is also convenient to take out a blood bag individually when taking it out, avoiding the waste of nitrogen.
