[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0023] The present invention discloses a device for holding cell cryopreservation tubes. The present invention designs a transparent plate body 02 with a through hole 020. On one side surface of the transparent plate body 02, a plurality of transparent flexible tubes 03 respectively communicating with the plurality of through holes 020 are provided. This device can perform water bath heating on multiple cell cryopreservation tubes 01 at one time, and this design can improve the resuscitation efficiency of cryopreserved cells; the transparent flexible tubes 03 can protect the cell cryopreservation tubes 01 to avoid contact between the cell cryopreservation tubes 01 and the water in the water bath. At the same time, the staff can also clearly observe the thawing situation inside the cell cryopreservation tubes 01;

[0026] By designing the top post 040, the top post 040 can further restrict the vertical displacement of the cell cryopreservation tube 01, ensuring that the cell cryopreservation tube 01 can be reliably immersed in the water in the water bath pot.

[0027] Embodiment

[0028] See the appendix Figures 1-3 It is a schematic diagram of the overall and partial structures of an embodiment of the present utility model. The present utility model specifically discloses a device for containing cell cryopreservation tubes. The device containing the cell cryopreservation tubes 01 can be erected on the water bath pot. The cell cryopreservation tubes 01 contain cryopreserved cells, and the hot water in the water bath pot can transfer heat to the cell cryopreservation tubes 01 to accelerate the resuscitation of the cells in the cell cryopreservation tubes 01;

[0029] The device includes:

[0030] A transparent plate body 02, on the plate surface of the transparent plate body 02, a plurality of circular through holes 020 are evenly arranged. The aperture of the through holes 020 is larger than the maximum outer diameter of the cell cryopreservation tube 01. On one side plate surface of the transparent plate body 02, a plurality of transparent rod bodies 021 are integrally formed vertically;

[0031] A plurality of transparent flexible tubes 03 with a circular cross-sectional outer contour. One end of each transparent flexible tube 03 is open and the other end is closed. The open ends of the plurality of transparent flexible tubes 03 are hermetically fixed to the side plate surface of the transparent plate body 02 where the transparent rod bodies 021 are provided. Each of the plurality of through holes 020 is limited inside the open ends of the plurality of transparent flexible tubes 03, that is, the through holes 020 communicate with the inside of the transparent flexible tubes 03. On the outer peripheral side of each transparent flexible tube 03, a plurality of transparent rod bodies 021 are evenly arranged, and the outer side wall of the transparent flexible tube 03 is in close contact with the side wall of the transparent rod bodies 021; The cell cryopreservation tube 01 can be contained in the transparent flexible tube 03, and the lower end of the cell cryopreservation tube 01 can abut against the inner wall of the closed end of the transparent flexible tube 03;

[0032] Since the transparent flexible tube 03 is soft in texture, when the user arranges the transparent plate body 02 inclined relative to the horizontal plane, if there is no transparent rod body 021, due to the tendency of the cell cryopreservation tube 01 to be vertically arranged under its own gravity, the transparent flexible tube 03 containing the cell cryopreservation tube 01 will be bent and deformed at the position above the cell cryopreservation tube 01; while in this application, there is a transparent rod body 021. When the transparent plate body 02 is arranged inclined relative to the horizontal plane, the transparent rod body 021 will limit the cell cryopreservation tube 01, so that the cell cryopreservation tube 01 also inclines with the inclination of the transparent plate body 02, and the cell cryopreservation tube 01 will not be vertically arranged due to its own gravity, avoiding the above-mentioned bending deformation of the transparent flexible tube 03.

[0033] A transparent cover plate 04, the transparent cover plate 04 can closely adhere to the plate surface on the side of the transparent plate body 02 away from the transparent rod body 021. The transparent cover plate 04 does not affect the user's observation of the cell cryopreservation tube 01 inside the transparent flexible tube 03. At the same time, the transparent cover plate 04 will also limit the upward floating of the cell cryopreservation tube 01 inside the transparent flexible tube 03. Because when the transparent flexible tube 03 containing the cell cryopreservation tube 01 is immersed in the water in the water bath pot, the cell cryopreservation tube 01 will move upward due to the buoyancy of the water. The transparent cover plate 04 can limit the upward movement of the cell cryopreservation tube 01 to ensure that the cell cryopreservation tube 01 is in full contact with the water in the water bath pot.

[0034] On the side plate surface of the transparent cover plate 04 close to the transparent plate body 02, a plurality of top columns 040 with a cross-shaped cross-section are integrally formed vertically. The cross-section of the top column 040 is cross-shaped. The plurality of top columns 040 can be inserted into the plurality of transparent flexible tubes 03 respectively. When the transparent flexible tube 03 containing the cell cryopreservation tube 01 is immersed in the water in the water bath pot, the cell cryopreservation tube 01 will move upward due to the buoyancy of the water. At this time, the end of the top column 040 away from the transparent cover plate 04 will abut against the upper end of the cell cryopreservation tube 01 located inside the transparent flexible tube 03. The top column 040 will further limit the cell cryopreservation tube 01 to ensure that the cell cryopreservation tube 01 is reliably immersed in the water in the water bath pot. At the same time, the top column 040 is also made of transparent material, which will not affect the staff's observation of the cell cryopreservation tube 01.

[0035] At one end of the transparent cover plate 04 away from the top column 040, a handle 041 is integrally formed. The handle 041 is also transparent. The staff can hold and transfer the transparent cover plate 04 by using the handle 041.

[0036] The tube length of the transparent flexible tube 03 is greater than the tube length of the cell cryopreservation tube 01 to ensure that the cell cryopreservation tube 01 can be fully immersed in the water in the water bath pot.

[0037] One end of the cell cryopreservation tube 01 close to the transparent plate body 02 is arranged between the two ends of the transparent rod body 021. This design ensures that the transparent rod body 021 can effectively limit the cell cryopreservation tube 01. For example, when the transparent plate body 02 is arranged obliquely, the transparent rod body 021 can also force the cell cryopreservation tube 01 to be arranged obliquely; at least three transparent rod bodies 021 are evenly arranged on the outer peripheral side of the transparent flexible tube 03. This design can improve the limiting effect of the transparent rod body 021 on the cell cryopreservation tube 01.

[0038] On the side plate surface of the transparent plate body 02 far from the transparent rod body 021, two handle twos 022 are integrally formed. The transparent cover plate 04 is located between the two handle twos 022. The staff can transfer the transparent plate body 02 through the handle twos 022.

[0039] When the device is in use:

[0040] First step, open the transparent cover plate 04, place the cell cryopreservation tube 01 into the transparent flexible tube 03, and then cover the transparent cover plate 04;

[0041] Second step, horizontally place the transparent plate body 02 on a water bath pot filled with water. The water bath pot is a circular pot body or a rectangular pot body. The length of the transparent plate body 02 is greater than the outer diameter of the water bath pot. When the transparent plate body 02 is horizontally arranged, its lower plate surface abuts against the edge of the water bath pot, and the transparent rod body 021 and the flexible transparent tube are both limited inside the water bath pot. And at this time, the cell cryopreservation tube 01 in the transparent flexible tube 03 is located below the liquid level of the water in the water bath pot.

[0042] During the process of heat exchange between the water in the water bath pot and the cell cryopreservation tube 01 in the transparent flexible tube 03, the staff can observe the cell cryopreservation tube 01 through the transparent cover plate 04, the top column 040 and the through hole 020, or pick up the transparent plate body 02 to observe. At the same time, during the process of the cell cryopreservation tube 01 heating up in the water bath, the staff needs to pick up the transparent plate body 02 and arrange it obliquely or shake it relative to the horizontal plane, that is, the cell cryopreservation tube 01 is arranged obliquely or shaken, so as to facilitate the resuscitation of the cells in the cell cryopreservation tube 01.

[0043] In this specification, each embodiment is described in a progressive manner. The key point of each embodiment is to illustrate the differences from other embodiments. The same or similar parts among the embodiments can be referred to each other.

[0044] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present utility model. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model. Therefore, the present utility model will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
