Detailed Description
The utility model is further described in connection with the following detailed description, in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the utility model easy to understand.
Example 1
Fig. 1 to 6 are schematic structural views showing an embodiment of a safety storage device for immune stem cells according to the present utility model, referring to fig. 1 to 6, a safety storage device for immune stem cells according to the present utility model, the main body of which includes an outer protective tub 100, an inner tub 200, and a stem cell holder 300.
The side wall of the outer protection barrel 100 is fixed with an evacuating pipe 100a communicated with the inner cavity of the outer protection barrel 100, and the top is fixed with an annular baffle 100b;
the inner storage barrel 200 is fixed in the inner cavity of the outer protection barrel 100, a storage hole 200a is formed in the top of the inner storage barrel 200, a sealing cover 200b is hinged to the storage hole 200a, a liquid nitrogen injection pipe 200c is fixed to the top of the inner storage barrel 200, a threaded rod 200d is rotatably installed on the inner storage barrel 200, and a guide rod 200e is fixed to the inner part of the inner storage barrel 200;
the stem cell placing rack 300 is placed in the inner cavity of the internal storage barrel 200, a slot 300a for placing a stem cell box is formed in the side wall of the stem cell placing rack, mounting plates 300b are symmetrically fixed on the side wall, a threaded hole 300c meshed with the threaded rod 200d is formed in one mounting plate 300b, and a guide hole 300d sleeved on the guide rod 200e is formed in the other mounting plate 300 b.
Specifically, firstly, the stem cell box is inserted into the slot 300a for placement, then the threaded rod 200d is rotated to drive the stem cell rack 300 to move into the inner cavity of the inner storage barrel 200, then the sealing cover 200b is closed, then liquid nitrogen is injected into the inner cavity of the inner storage barrel 200 through the liquid nitrogen injection pipe 200c, so that the stem cells are preserved in a low-temperature environment, and then the vacuum is pumped between the outer protective barrel 100 and the inner storage barrel 200 through the vacuumizing pipe 100a, so that the temperature exchange between the inner storage barrel 200 and the external environment is reduced. When stem cells need to be taken, the threaded rod 200d is rotated to drive the stem cell placing frame 300 to ascend, and then the sealing cover 200b is opened, so that the stem cell box can be directly taken after the sealing cover 200b is opened, the opening time of the sealing cover 200b is reduced, the loss of liquid nitrogen is reduced, after the stem cell box is taken out, the stem cell placing frame 300 is placed back, the sealing cover 200b is closed, and the phenomenon that the liquid nitrogen is lost due to the fact that the process of taking the stem cell box out of the bottom after the sealing cover 200b is opened is long is avoided.
Further, when the stem cell holder 300 is lifted up below the cover 200b, it is also necessary to manually open the cover 200b, and then manually close the cover 200b after taking out the stem cell cassette, which increases the manpower loss.
