Description

Technical Field

[0001] This invention belongs to the technical field of biological sample preservation, specifically relating to a cell cryopreservation tube that is easy to hold. Background Technology

[0002] In fields such as cell biology, medical research, and biological sample preservation, cryovials are commonly used tools for storing cell samples. Cell samples typically need to be preserved in a low-temperature environment, such as in liquid nitrogen tanks, to maintain cell viability and biological characteristics;

[0003] However, existing cell cryovials present several significant problems in practical operation. When retrieving cell cryovials from a cryogenic environment (such as liquid nitrogen), traditional cryovials lack effective clamping structures. Operators typically use long-handled clamps, but due to the smooth surface of the cryovials and the increased difficulty of handling them at low temperatures, uneven hand pressure can easily cause the clamps to loosen, leading to the cryovials falling off. This can not only result in the loss of precious cell samples but also pose safety risks, such as liquid nitrogen splashing and injuring the operator. Furthermore, there is a lack of convenient and stable clamping methods when cell cryovials are placed in a liquid nitrogen container for pre-cooling. Conventional methods struggle to precisely control the position and state of the cryovials, hindering operational efficiency and sample processing accuracy. Utility Model Content

[0004] The purpose of this invention is to provide a cell cryopreservation tube that is easy to clamp, in order to solve the problems mentioned in the background art, such as the lack of an effective clamping structure when the existing cell cryopreservation tubes are taken out of the low temperature environment (such as liquid nitrogen tank), the smooth surface and the difficulty of low temperature operation, the long-handled tube clamps are easy to loosen and cause the cryopreservation tube to fall off, resulting in sample loss and safety risks, and the lack of a convenient and stable clamping method during liquid nitrogen precooling, making it difficult to accurately control the position and state, which affects the efficiency of operation and the accuracy of sample processing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cell cryopreservation tube that is easy to clamp, comprising a cell cryopreservation tube body and a sealing retaining ring disposed on the circular outer wall at the top of the cell cryopreservation tube body. The top of the cell cryopreservation tube body is provided with an external threaded tube opening. A threaded sealing cap is sleeved on the external thread of the external threaded tube opening. The circular outer wall of the threaded sealing cap is provided with a plurality of inwardly recessed protective grooves at equal intervals. The top edge of the threaded sealing cap is treated with an arc surface passivation. A convenient clamping device is sleeved on the outside of the threaded sealing cap.

[0006] Preferably, the convenient clamping device includes a hard plastic sleeve, a damping pad, a clamping baffle A, a low-temperature resistant adhesive sheet, and a clamping baffle B. The inner wall of the hard plastic sleeve is provided with a damping pad, and the hard plastic sleeve is sleeved on the outside of the threaded sealing cap through the damping pad. The outer walls of both the left and right ends of the hard plastic sleeve are provided with clamping baffle A and clamping baffle B. Both clamping baffle A and clamping baffle B extend vertically upward. The outer wall of the upper left end of the center of clamping baffle A and the outer wall of the upper right end of the center of clamping baffle B are both attached with low-temperature resistant adhesive sheets.

[0007] Preferably, the convenient clamping device further includes a clamping top plate and a semi-circular tweezer clamping insertion hole. The clamping top plate is connected between the top ends of the clamping baffle A and the clamping baffle B. Semi-circular tweezer clamping insertion holes are provided on both the left and right sides of the center of the clamping top plate.

[0008] Preferably, the low-temperature resistant adhesive sheet is an organic silicone adhesive sheet, and the two semi-circular tweezers clamping holes can be directly inserted into the open tweezers, and the tweezers can form a clamping effect in the two semi-circular tweezers clamping holes after being pinched.

[0009] Preferably, the damping pad and the threaded sealing cap are interference-fitted, and the damping pad can move downward outside the threaded sealing cap through a coordinated operation of rotation and downward pressure.

[0010] Preferably, a sealing gasket is provided on the inner wall of the top of the threaded sealing cap. After the threaded sealing cap is tightened outside the external threaded pipe opening, the sealing gasket can be tightly pressed against the top of the external threaded pipe opening.

[0011] Preferably, the outer diameter of the threaded sealing cap is equal to the outer diameter of the sealing retaining ring, and the bottom end of the threaded sealing cap can be tightly pressed against the outer wall of the top of the sealing retaining ring after tightening.

[0012] Preferably, the outer wall of the front end of the cell cryopreservation tube body is provided with a capacity scale line, and the bottom end of the cell cryopreservation tube body is provided with a placement base tube, the placement base tube having the same outer diameter as the cell cryopreservation tube body.

[0013] Compared with the prior art, this utility model provides a cell cryopreservation tube that is easy to clamp, and has the following beneficial effects:

[0014] This invention features a novel, convenient clamping device added to the outside of the threaded sealing cap of the cell cryopreservation tube. This device allows for easier and safer removal of the cell cryopreservation tube from the liquid nitrogen tank. When the cell cryopreservation tube is placed in the liquid nitrogen tank and needs to be removed, the unique design of this device allows the long-handled clamp to hold it better and more firmly. The long-handled clamp, by holding the cryogenic adhesive pad, utilizes its adhesive properties to effectively prevent the clamp from loosening due to uneven force applied by the palm, thus preventing the cell cryopreservation tube from falling off during removal. This greatly improves operational stability and reliability. Furthermore, during the pre-cooling stage of the cell cryopreservation tube in the liquid nitrogen box, tweezers can be inserted into the semi-circular tweezers clamping hole and squeezed tightly, providing convenience for operation. In addition, the damping pad and the threaded sealing cap are interference-fitted, allowing for flexible use through rotation and downward pressure. Overall, this convenient clamping device comprehensively improves the ease of use and safety of cell cryopreservation tubes in different operating scenarios. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides, for example Figure 1-5 The illustration shows a cell cryopreservation tube designed for easy clamping, comprising a cell cryopreservation tube body 2 and a sealing ring 4 disposed on the circular outer wall at the top of the cell cryopreservation tube body 2. The top of the cell cryopreservation tube body 2 has an externally threaded port 7, and a threaded sealing cap 5 is fitted onto the external thread of the externally threaded port 7. The circular outer wall of the threaded sealing cap 5 has multiple inwardly recessed protective grooves at equal intervals. These grooves increase friction when the user holds the threaded sealing cap 5, facilitating unscrewing and tightening, thus improving ease of operation. Furthermore, when the cryopreservation tube is subjected to collision or compression, the protective grooves act as a buffer, reducing the impact on the threaded sealing cap 5 and the entire cryopreservation tube structure, protecting the integrity of the cryopreservation tube, and reducing the risk of seal failure due to external forces. The top edge of the threaded sealing cap 5 is rounded and passivated. The outer wall at the front end of the cell cryopreservation tube body 2 also has volume graduation lines 3. Accurately knowing the volume of the cell suspension or other samples inside the cryopreservation tube is crucial during cell cryopreservation. The volume scale lines 3 on the outer wall of the front end of the cryopreservation tube body 2 provide users with an intuitive volume reference. These scale lines are drawn based on precise measurements and calibrations, helping researchers accurately determine the amount of sample added to the cryopreservation tube. During operation, by observing the position of the liquid on the scale lines, researchers can precisely control the sample volume, ensuring that the sample volume in each cryopreservation tube meets the experimental requirements, thus improving the accuracy and reproducibility of the experiment. The bottom of the cryopreservation tube body 2 is equipped with a base tube 1, which has the same outer diameter as the cryopreservation tube body 2. The function of the base tube 1 is to provide a stable foundation for the cryopreservation tube. When the cryopreservation tube is placed on the lab bench or other storage containers, the base tube 1 can increase the contact area with the support surface, reducing the risk of the cryopreservation tube tipping over. This design helps to keep the cryopreservation tube upright during storage, avoiding damage or leakage of the internal sample due to tilting or tipping, and ensuring the safe storage of cell samples.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a sealing gasket 8 is provided on the inner wall of the top of the threaded sealing cap 5. After the threaded sealing cap 5 is tightened on the outside of the external threaded tube opening 7, the sealing gasket 8 can be tightly pressed against the top of the external threaded tube opening 7. The outer diameter of the threaded sealing cap 5 is equal to the outer diameter of the sealing retaining ring 4. After the threaded sealing cap 5 is tightened, the bottom end can be tightly pressed against the outer wall of the top of the sealing retaining ring 4. The sealing design of this cell cryopreservation tube is intended to ensure the stability of the cryopreservation environment and prevent external factors from interfering with the cell samples. The external threaded tube opening 7 at the top of the cell cryopreservation tube body 2 is connected to the threaded sealing cap 5 by a threaded connection. When the threaded sealing cap 5 is tightened on the external threaded tube opening 7, the sealing gasket 8 on the inner wall of the top will be tightly pressed against the external threaded tube opening 7. The sealing structure, located at the top of the external threaded tube opening 7, utilizes the elastic deformation of the sealing gasket 8 to fill any tiny gaps that may exist in the threaded connection, forming a reliable sealing barrier. This effectively prevents liquid leakage and the entry of external air and moisture into the cryopreservation tube, providing a stable preservation environment for cell samples. At the same time, the outer diameter of the threaded sealing cap 5 is equal to the outer diameter of the sealing retaining ring 4, and after tightening, the bottom end is tightly pressed against the outer wall of the top of the sealing retaining ring 4. The sealing retaining ring 4 not only plays a role in positioning and strengthening the seal, but also further prevents external substances from intruding along the gap between the outer wall of the cryopreservation tube and the threaded sealing cap 5, enhancing the overall sealing performance and ensuring the reliability of the cell cryopreservation environment.

[0024] like Figure 1 and Figure 5As shown, a convenient clamping device 6 is fitted onto the outside of the threaded sealing cap 5. The convenient clamping device 6 includes a hard plastic sleeve 9, a damping pad 10, a clamping baffle A11, a low-temperature resistant adhesive sheet 12, and a clamping baffle B15. The inner wall of the hard plastic sleeve 9 is provided with the damping pad 10, and the hard plastic sleeve 9 is fitted onto the outside of the threaded sealing cap 5 through the damping pad 10. Clamping baffles A11 and B15 are provided on the outer walls of both the left and right ends of the hard plastic sleeve 9. All five clamps extend vertically upwards. Low-temperature resistant adhesive patches 12 are attached to the outer wall of the upper left end of the center of clamping baffle A11 and the outer wall of the upper right end of the center of clamping baffle B15. When the cell cryopreservation tubes need to be removed from low-temperature environments such as liquid nitrogen tanks, the long-handled clamps can achieve stable clamping by gripping the low-temperature resistant adhesive patches 12 on the outer walls of clamping baffles A11 and B15. The low-temperature resistant adhesive patches 12 are made of silicone rubber and have good low-temperature resistance and adhesion. In terms of performance, the silicone adhesive pad maintains its stickiness even at low temperatures, firmly adhering to the long-handled tube clamp. This effectively prevents the long-handled tube clamp from loosening due to uneven force applied by the palm, thus preventing the cell cryopreservation tube from falling off during retrieval and ensuring the safety and stability of the operation. The damping pad 10 and the threaded sealing cap 5 are interference-fitted. The damping pad 10 can move downwards outside the threaded sealing cap 5 through the coordinated operation of rotation and downward pressure. The interference fit ensures that the hard plastic sleeve 9 fits tightly and is not easy to fall off when it is fitted outside the threaded sealing cap 5. The interference fit design has been carefully considered to ensure the connection stability between the hard plastic sleeve 9 and the threaded sealing cap 5, and also allows the damping pad 10 to move downwards outside the threaded sealing cap 5 through the coordinated operation of rotation and downward pressure. This feature not only facilitates the installation and disassembly of the device, but also allows the position of the hard plastic sleeve 9 to be adjusted according to actual needs to better adapt to different operating scenarios.

[0025] like Figure 1 and Figure 5 As shown, the convenient clamping device 6 also includes a clamping top plate 13 and semi-circular tweezer clamping holes 14. The clamping top plate 13 is connected between the top ends of the clamping baffle A11 and the clamping baffle B15. Semi-circular tweezer clamping holes 14 are provided on both the left and right sides of the center of the clamping top plate 13. The low-temperature resistant adhesive sheet 12 is an organic silicone adhesive sheet. Tweezers in an open state can be directly inserted into the two semi-circular tweezer clamping holes 14. After the tweezers are squeezed, they can form a clamping effect in the two semi-circular tweezer clamping holes 14. In scenarios such as pre-cooling of cell cryovials in liquid nitrogen boxes, the two ends of the tweezers can be directly inserted into the two semi-circular tweezer clamping holes 14 respectively, and a clamping effect can be formed by squeezing the tweezers. This design provides operators with more options. Whether using long-handled tube clamps or tweezers, cell cryovials can be clamped conveniently and firmly, meeting the needs of different experimental environments and operating habits, and improving the flexibility and convenience of cell cryovial operation.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
