Description

Technical Field

[0001] The utility model relates to the technical field of stem cell storage, in particular to a spatially adjustable stem cell storage device. Background Art

[0002] Stem cells are cells with special abilities that have the potential to self-renew and differentiate into a variety of different cell types. They play an important role in the developmental process and also play a key role in maintaining and repairing tissues in adults. Stem cells are usually divided into multiple types, including embryonic stem cells and adult stem cells, which have different characteristics and potentials. Stem cells usually need to be preserved for a long time for future research or clinical applications. Storage devices provide a stable environment to ensure that stem cells maintain their biological activity and cellular properties in a frozen or refrigerated state.

[0003] Traditional stem cell storage devices mainly place stem cells into cryotubes first, then place the cryotubes into cryoboxes, finally place the cryoboxes into liquid nitrogen tank basket racks, and finally place the liquid nitrogen tank basket racks into liquid nitrogen tanks to ensure the preservation of samples and maintain their biological activity.

[0004] However, the traditional stem cell storage device cannot adjust the space inside the liquid nitrogen tank basket storage rack. Since the space inside the liquid nitrogen tank basket storage rack is fixed, it may not be able to meet the storage needs of stem cell cryopreservation tubes or cryopreservation boxes of different sizes, shapes or specifications. In addition, the existing liquid nitrogen tank basket storage rack for placing stem cells generally has many layers, and a stem cell cryopreservation box is placed on each layer. However, the cell cryopreservation boxes on each placement layer are only fixed by a wire, and the iron wire is not fixed stably. Moreover, when the stem cell cryopreservation box needs to be taken out, the iron wire needs to be pulled out first. When the operation is unstable, all the cell cryopreservation boxes often slide off the liquid nitrogen tank basket storage rack, and the stem cell cryopreservation tubes scatter out, which is not conducive to the storage of stem cells. Therefore, it is necessary to propose a new space-adjustable stem cell storage device to solve the above problems. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a space-adjustable stem cell storage device, aiming to improve the problems in the prior art that the space in the placement rack cannot be adjusted and the stem cell freezing boxes are unstable and easy to scatter.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0012] As a further description of the above technical solution:

[0022] The utility model has the following beneficial effects:

[0023] 1. In the utility model, the layer plate realizes its lifting function by turning the knob 1. When the knob 1 is turned, the structures such as the worm gear, the worm and the slider will be linked to realize the movement of the layer plate, so as to adjust the space between the layer plates to meet the storage requirements of stem cell cryopreservation boxes of different specifications (especially different specifications of stem cell cryopreservation tubes are placed in cryopreservation boxes of different heights. By moving the layer plate up and down, the placement space of the cryopreservation boxes can be adjusted to meet the storage requirements of cryopreservation boxes of different heights). This provides greater flexibility, allowing laboratories or clinical units to customize storage space according to specific experimental or treatment needs, solving the problem of being unable to adjust the space.

[0034] Specifically, the knob 14 is turned to drive the worm 12 to rotate, and the engagement between the worm 12 and the worm gear 13 is utilized to ensure the transmission of large torque and moment, thereby driving the threaded tube 10 to rotate through the worm gear 13, and then driving the slider 11 to rise and fall through the threaded tube 10, and then driving the layer plate 8 to rise and fall through the slider 11, so as to adjust the space between the layer plates 8, which can more effectively utilize the space in the placement rack, reduce space waste and maximize storage efficiency. By optimizing the storage layout, stem cell freezing boxes of different sizes, shapes and specifications can be placed and stored without increasing the storage cost. At the same time, the hollow hole 5 can make it easier for liquid nitrogen to enter and exit to ensure the needs of stem cell storage.

[0035] Reference Figure 2 and Figure 3 The stem cell freezing box fixing assembly includes a clamping shell 9, and a fixing block 22 is fixedly connected inside the clamping shell 9.

[0036] Specifically, the stem cell freezing box is fixed to prevent it from moving (or sliding or scattering) during storage or removal.

[0037] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 The fixed block 22 is rotatably connected with the positive and negative threaded rod 19 inside, and the two ends of the positive and negative threaded rod 19 are fixedly connected with the knob 28.
