Technical Field

[0001] The utility model relates to the technical field of stem cell freezing box brackets, and specifically relates to a portable stem cell freezing box bracket. Background Art

[0002] Stem cells are a type of multipotent cells with the ability to self-replicate. Under certain conditions, they can differentiate into multiple functional cells. According to the developmental stage of stem cells, they are divided into embryonic stem cells and adult stem cells. According to the developmental potential of stem cells, they are divided into three categories: totipotent stem cells, pluripotent stem cells and unipotent stem cells. Stem cells are a type of undifferentiated, immature cell that has the potential to regenerate various tissues, organs and the human body. The medical community calls them universal cells. Stem cells generally need to be stored in cryopreservation boxes and freezers, but in the culture and experiments involving stem cells, the stem cell cryopreservation boxes often need to be transported.

[0003] The Chinese utility model patent with application number: CN201820934627.8 discloses a portable stem cell freezing box stand, including a shell, a plurality of storage plates arranged in sequence from top to bottom in the shell, a vertically arranged baffle, and a clamping mechanism arranged at the top and bottom of the shell for clamping the baffle; wherein the clamping mechanism is composed of a Z-shaped slideway opened on the left side of the shell, a bending movable plate located in the right end of the Z-shaped slideway, and a compression spring connecting the bending movable plate and the baffle, and the baffle can slide left and right in the Z-shaped slideway, and is pressed and fixed by the bending movable plate at the right end of the Z-shaped slideway under the action of the compression spring. The portable stem cell freezing box stand of the utility model fixes the baffle to the middle of the front of the shell through the clamping mechanism, so that the freezing box is fixed in the shell, which reliably prevents the freezing box from falling off and loosening; and it is stable and reliable, which improves the experimental efficiency.
