Description

Technical Field

[0001] The utility model belongs to the field of stem cell storage, in particular to a stem cell extraction storage tank. Background Art

[0002] Stem cells are a type of cell that has unlimited or immortal self-renewal capabilities and can produce at least one type of highly differentiated daughter cells. The definition of stem cells has been continuously revised over the years and defined at different levels. When storing stem cells, they need to be stored in a cryogenic storage tank filled with liquid nitrogen. Stem cells can be frozen in a cryogenic storage tank.

[0003] After searching, a Chinese patent discloses a stem cell cryogenic storage tank (authorization announcement number CN 218537492U). The patent technology includes an outer liner, an inner liner is arranged inside the outer liner, and screws are installed on both sides of the inner wall of the inner liner through a mounting seat, and hand wheels are installed on the top of the two screws, a support frame is arranged inside the inner liner, and the top surface of the support frame is rotatably connected to a rotating seat, and a storage groove is opened on the top surface of the rotating seat, and threaded blocks are welded on both sides of the outer wall of the support frame. In the utility model, first open the sealing cover and place a number of test tubes containing stem cells in the storage groove. During the placement process, the test tube exerts a force on the two clamping blocks and moves the two clamping blocks away from each other. At this time, the spring is stretched and deformed, and the two clamping blocks can firmly clamp and fix the test tube under the elastic force of the spring, which can prevent the test tube from shaking and greatly improve the stability of the test tube. On the other hand, it can clamp and fix test tubes of different specifications.

[0004] Although the storage tank in this technology can stably clamp the stem cell storage tube through the spring and the clamping block to prevent the test tube from shaking, it is inconvenient to place the test tube due to the rebound force of the spring in the device, and the clamping blocks on both sides cannot be controlled to automatically open and close. In addition, when storing and accessing the stem cell storage tube in the device, the sealing cover needs to be opened, which will cause the cavity in the tank to be exposed to the air, resulting in a large amount of liquid nitrogen loss, thereby causing the temperature in the tank to rise rapidly, affecting the storage environment of the stem cells, and also causing a waste of resources, which is not conducive to cost saving.
