Technical Field

[0001] This utility model relates to the field of stem cell cryopreservation tube safety protection technology, and in particular to an explosion-proof safety cover for stem cell cryopreservation tubes. Background Technology

[0002] In the field of stem cell research and clinical applications, cryopreservation tubes are the core carriers for the long-term stable storage of stem cells, and they need to be preserved for a long time in an ultra-low temperature environment of liquid nitrogen. However, cryopreservation tubes are prone to rupture and explosion during freezing and thawing due to drastic changes in internal and external pressure differences, which can damage precious stem cell samples and generate sharp fragments that can cause scratches to operators, seriously affecting experimental safety and sample preservation reliability.

[0003] Most traditional cryopreservation tube protective sleeves typically employ an integrated wrapping design that fits snugly against the cryopreservation tube during use. This requires disassembling the protective sleeve during installation and removal, which prevents quick removal of the protective sleeve for direct sampling in emergency situations. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an explosion-proof safety cover for stem cell cryopreservation tubes, which aims to improve the problem in the prior art that the protective cover needs to be disassembled for assembly and disassembly, making it impossible to quickly remove the protective cover and directly operate for sampling in emergency scenarios.

[0018] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example 1

[0019] Reference Figure 1 and Figure 2 An embodiment of this utility model provides: an explosion-proof safety cover for stem cell cryopreservation tubes, including a handle 1, a cryopreservation tube shell 2 fixedly connected inside the handle 1, a cryopreservation tube body 3 threadedly connected inside the handle 1, the outside of the cryopreservation tube body 3 located inside the cryopreservation tube shell 2, a protective cover 4 snapped into the inside of the handle 1, a quick-release structure 5 installed on the outside of the protective cover 4, the quick-release structure 5 including a buckle 51, the outside of the buckle 51 fixedly connected to the outside of the protective cover 4, the outside of the buckle 51 snapped into the inside of the handle 1, and a fixing component provided inside the handle 1; Specifically, the handle 1 is used to fix the cryovial body 3 and the cryovial shell 2. The cryovial shell 2 and the cryovial body 3 are integrated and used to fix the cryovial body 3. The cryovial body 3 is a transparent tube with graduations and is used to store stem cells. The protective cover 4 is a transparent cover used to protect the cryovial shell 2 and the cryovial body 3 and to observe their internal condition. The quick-release structure 5 is used to quickly remove the protective cover 4. The buckle 51 is used to connect the fixing component inside the handle 1. The fixing component is used to quickly remove the protective cover 4, thereby achieving the effect of quickly removing the protective cover 4 with one rotation. This improves the problem in the prior art that the protective cover needs to be removed for disassembly and assembly, which makes it impossible to directly take samples after quick removal of the protective cover in emergency scenarios.

[0020] Reference Figure 1 and Figure 3 The fixing component includes a first groove 52, the outside of which is disposed inside the handle 1. The handle 1 has a second groove 53 inside, the outside of which is located inside the second groove 53, and the outside of the first buckle 51 is engaged inside the first groove 52. Specifically, groove 1 52 is used to engage buckle 1 51. When buckle 1 51 is inserted into groove 2 53, buckle 1 51 is rotated so that the protruding part of buckle 1 51 engages inside groove 1 52, thus completing the operation of fixing the protective cover 1 4. Groove 2 53 is used to insert buckle 1 51 into the handle 1.

[0021] Reference Figure 2 The inner bottom of the protective cover 4 is fixedly connected to the protective cover 7, the outside of the protective cover 4 is located inside the protective cover 7, and the outside of the cryopreservation tube body 3 is located inside the protective cover 7. Specifically, the first protective cover 4 is used to connect the second protective cover 7, which is a silicone layer. When the cryopreservation tube body 3 suddenly explodes, the second protective cover 7 first intercepts the fragments inside, concentrating the dispersed fragments inside and preventing fragments from flying. Example 2

[0022] Reference Figure 4 and Figure 5 The protective cover 4 is equipped with a quick-release structure 6, which includes a fixing post 61, which is fixedly connected to the inside of the protective cover 4. The fixing post 61 is also fixedly connected to a fixing post 62. A moving post 63 is provided on the outside of the fixing post 62, and the outside of the moving post 63 fits against the upper surface of the fixing post 61. The inside of the protective cover 4 is provided with a groove 69, and the outside of the moving post 63 is located inside the groove 69. A fixing ball 64 is fixedly connected to the outside of the fixing post 62. A fixing bracket 65 is fixedly connected to the inside of the handle 1. The outside of the fixing ball 64 is located inside the fixing bracket 65 and the handle 1. The outside of the fixing post 62 is located inside the handle 1. A fixing post 66 is provided inside the fixing bracket 65. A buckle 67 is fixedly connected to the outside of the fixing post 66. A spring 68 is provided on the outside of the fixing post 66, and the buckle 67 is engaged with the outside of the fixing ball 64. Specifically, quick-release structure 2 6 is used for quick disassembly of protective cover 1 4; fixing post 1 61 is used to connect protective cover 1 4 and fix it inside; fixing post 2 62 is used to connect fixing ball 64 and fixing moving post 63; moving post 63 is used to disengage buckle 2 67 from fixing ball 64; fixing ball 64 is used to engage buckle 2 67; fixing bracket 65 is used to stabilize fixing post 3 66 and buckle 2 67; fixing post 3 66 is used to connect buckle 2 67 and spring 68; buckle 2 67 is used to engage fixing ball 64; spring 68 is used to rebound fixing post 3 66; groove 3 69 is used to... The second latch 67 moves inside. When it is necessary to remove the first protective cover 4, press the handle 1. The handle 1 drives the fixed bracket 65, the second latch 67, and the third fixed post 66 to move downward. When the bottom of the fixed bracket 65 contacts the bottom of the third groove 69, the second latch 67 will engage the moving post 63. At this time, pull the fixed bracket 65 back, and the second latch 67 will drive the moving post 63 to move in the opposite direction. When the moving post 63 contacts the fixed ball 64, the third fixed post 66 will slide out from the outer contour of the moving post 63 and the fixed ball 64, thereby achieving the effect of quickly removing the first protective cover 4.

[0023] Working principle: When liquid nitrogen needs to be stored, insert buckle 51 into groove 53 inside handle 1, rotate buckle 51 so that it engages inside groove 52. In the event of an explosion, protective shield 7 and protective shield 4 can disperse the impact force. This structure not only allows for quick installation and replacement of protective shield 4, but also prevents injury to workers in case of emergencies.
