Description

Technical Field

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

[0002] Stem cells are a type of cells with unlimited or immortal self-renewal ability, and can produce at least one type of highly differentiated daughter cells. Over the years, the definition of stem cells has been continuously revised and defined from different levels. Most biologists and medical scientists believe that stem cells are a type of cells derived from embryos, fetuses, or adults with the ability of unlimited self-renewal and proliferation and differentiation under certain conditions. When stem cells are cryopreserved, generally, multiple test tubes containing stem cells are placed in a storage box, and then liquid nitrogen is filled for heat preservation. However, when taking out a certain stem cell test tube, it is easy to cause the leakage of liquid nitrogen. At this time, the temperature in the storage box will fluctuate, which will affect the storage of stem cells in other test tubes. Therefore, we propose a stem cell storage device to solve the above problems. Content of the Utility Model

Specific implementation manners

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment

[0023] Such as Figure 1 、 Figure 2 、 Figure 3 And Figure 4As shown in the figure, a stem cell storage device proposed by an embodiment of the present utility model includes a base 1. The top of the base 1 is rotatably connected to a rotating rod 2 through a bearing. Two annular shells 3 are fixed on the surface of the rotating rod 2. Rotating rings 14 are fixed on the surfaces of the annular shells 3. When searching for the stored cell test tubes 6, it is convenient for the staff to rotate the annular shells 3. Circular plates 4 are fixed inside the through holes equidistantly opened at the tops of the two annular shells 3. Placing cylinders 5 are fixed inside the through holes opened at the tops of the circular plates 4. Cell test tubes 6 are placed inside the placing cylinders 5. Sealing plugs 7 are tightly inserted inside the ports of the cell test tubes 6. Limiting seats 8 are fixed on the tops of the circular plates 4. Limiting holes 9 are opened on both side walls of the limiting seats 8. Cover plates 10 are placed inside the sunk grooves opened at the tops of the limiting seats 8. Limiting components 11 for engaging with the limiting holes 9 are arranged on the tops of the cover plates 10. Sealing components 12 for blocking the bottoms of the placing cylinders 5 are arranged on the surfaces of the placing cylinders 5. During the use of this stem cell storage device, when a certain cell test tube 6 needs to be taken out, the annular shell 3 can be operated to rotate to find the cell test tube 6 to be taken out. Then, the corresponding limiting component 11 is operated to separate the cover plate 10 from the limiting seat 8, and then the cell test tube 6 can be taken out. However, during the process of separating the cover plate 10 from the limiting seat 8, when the cover plate 10 is taken away, the restriction on the sealing component 12 below the cell test tube 6 to be taken out will be released, and then the sealing component 12 will block the placing cylinder 5 at this place, so that liquid nitrogen will not leak when the cell test tube 6 is taken away. When liquid nitrogen needs to be added to the inside of the annular shell 3 later, just open the inlet pipe at its top for adding.

[0024] As Figure 2 and Figure 3As shown, in some embodiments, the limit assembly 11 includes a guide seat 1101 fixed to the top of the cover plate 10. Two limit blocks 1102 adapted to the limit holes 9 are slidably connected inside the chute opened at the top of the guide seat 1101. One ends of the limit blocks 1102 all slidably penetrate through the guide seat 1101 and extend to its outside and are inserted into the corresponding limit holes 9. The tops of the limit blocks 1102 are all rotatably connected to a connecting rod 1103 through a pin shaft. The tops of the two connecting rods 1103 are rotatably connected to a moving plate 1104 through a pin shaft. A U-shaped plate 1105 is fixed to the top of the guide seat 1101. Two first springs 1106 are fixed inside the guide seat 1101. The other ends of the first springs 1106 are respectively fixedly connected to the corresponding limit blocks 1102. During use, with the cooperation of the U-shaped plate 1105, the staff can push the moving plate 1104 upward. After the moving plate 1104 moves upward, it can drive the two limit blocks 1102 to move in opposite directions through the cooperation of the two connecting rods 1103. At this time, the spring will be in a compressed state when the limit blocks 1102 move in opposite directions, and the limit blocks 1102 will slide out of the limit holes 9 after moving. At this time, the cover plate 10 can be separated from the limit seat 8. When installing the cover plate 10, repeat the above operation. After the cover plate 10 is attached to the limit seat 8 and the moving plate 1104 is released, the limit blocks 1102 can be re-inserted into the limit holes 9 under the reset force of the compressed first springs 1106. At this time, the limit seat 8 and the cover plate 10 can be connected and fixed.

[0025] As Figure 2 and Figure 3As shown, in some embodiments, the sealing assembly 12 includes a guiding ring 1201 fixed on the surface of the placing cylinder 5. T-shaped rods 1202 are slidably connected inside two relief holes opened at the top of the circular plate 4. Sealing rings 1207 are fixed inside the two relief holes opened at the top of the circular plate 4. The T-shaped rods 1202 are respectively located inside the corresponding sealing rings 1207, which can enhance the tightness of the fit between the T-shaped rods 1202 and the circular plate 4, avoiding the leakage of liquid nitrogen from the gap between the two. The tops of the T-shaped rods 1202 are in contact with the bottom of the cover plate 10. The bottoms of the two T-shaped rods 1202 slidably penetrate through the guiding ring 1201 and extend to its lower side and are fixed with a sealing seat 1203. A rubber sealing block 1204 adapted to the bottom end of the placing cylinder 5 is fixed on the top of the sealing seat 1203. Circular blocks 1205 are fixed on the surfaces of the T-shaped rods 1202. Second springs 1206 are fixed to the bottoms of the circular blocks 1205. The bottoms of the second springs 1206 are fixedly connected to the guiding ring 1201. When in use, when the cover plate 10 is removed, it will release the restriction on the T-shaped rods 1202, and then under the reset force of the compressed second springs 1206, the T-shaped rods 1202 can be driven to move upward through the circular blocks 1205. After the T-shaped rods 1202 move upward, they will drive the sealing seat 1203 to move upward. After the sealing seat 1203 moves upward, it can drive the rubber sealing block 1204 to block the bottom end of the placing cylinder 5, thereby preventing the leakage of liquid nitrogen after the cell test tube 6 is removed. When the cover plate 10 is installed, at this time, the rubber sealing block 1204 can release the blocking restriction on the bottom end of the placing cylinder 5.

[0026] As Figure 1 and Figure 2 As shown, in some embodiments, label seats 13 are fixedly arranged on the surface of the annular shell 3 in an annular array. Relief grooves are opened on the label seats 13. The provided label seats 13 are used for the staff to annotate the placed cell test tube 6, and the relief grooves opened on the label seats 13 facilitate the staff to take the annotation label paper.

[0027] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
