Example Embodiment
[0031] Example one:
[0032] figure 1 This is a schematic cross-sectional structure diagram of a stem cell cryopreservation box provided in an embodiment of this application.
[0033] Such as figure 1 As shown, 1 in the figure is a collection bag. The dry cell cryopreservation box includes: a box body 2, a box cover 3 and a plurality of partitions 4, wherein: a plurality of collection bags 1 and a plurality of partitions 4 are placed in the box 2 , The box cover 3 is located on the top of the box body 2 and is connected with the box body 2. The box cover 3 presses a plurality of partitions 4 and a plurality of collection bags 1 into the box body 2.
[0034] The box body 2 has a box bottom and four side walls, the top of which is an open end, that is, the top is provided with an opening. In order to adapt to the low-temperature environment during the freezing of stem cells, the material of the box 2 is a low-temperature resistant material. In the embodiment of the present application...
Example Embodiment
[0043] Embodiment two:
[0044] in figure 1 with figure 2 In this case, the box cover 3 cooperates with the slot on the box body 2 through the buckle 6 to press the collection bag 1 placed in the box body 2.
[0045] In addition, in other embodiments of this application, such as image 3 As shown, the pressure regulating and fixing device can also be a clamp column.
[0046] Such as image 3 As shown, 10 in the figure is a clamping column, and the clamping buckle 6 can be fixed to the clamping column 10, so by changing the clamping buckle 6 to connect with the clamping column 10 of different heights, the pressure of the cover 3 on the collection bag 1 can also be adjusted .
Example Embodiment
[0047] Embodiment three:
[0048] Figure 4 A method for cryopreservation of stem cells provided in the embodiments of this application.
[0049] Such as Figure 4 As shown, the method includes the following steps:
[0050] S100: Place multiple collection bags and multiple partitions alternately in a box with a bottom and side walls, and the partition at the top is the partition.
[0051] When placing collection bags and partitions, in order to facilitate pressure on the topmost partition, the stack height of multiple collection bags and multiple partitions is greater than the depth of the box, so that when the collection bags and partitions are placed, The top partition will emerge from the outside of the box to facilitate pressure on the top partition.
[0052] S200: Use the pressure adjusting fixing device and the buckle to apply pressure to the topmost partition in a direction pointing to the box body to flatten the multiple collection bags.
[0053] Since the collection bag is fi...
