Description

Technical Field

[0001] This utility model relates to the field of cryopreservation tube technology, and more specifically, to a contamination-resistant cryopreservation tube. Background Technology

[0002] Cryopreservation tubes are commonly used laboratory consumables in biological research and medicine, often used for the low-temperature transport and storage of tissue or cell samples. Cryopreservation tubes are typically made of high-hardness resin, resistant to high temperatures and pressures, and can be repeatedly frozen and thawed.

[0003] Existing cryopreservation tubes consist of a tube body and a cap screwed onto the tube body. The extremely small gap between the tube body and the cap results in poor sealing. During the cryopreservation process in liquid nitrogen, liquid nitrogen can easily seep in through the gap between the tube body and the cap, leading to cell contamination. Furthermore, during the thawing of cell cryopreservation tubes, they are usually heated in a water bath, where water can also easily seep in through the gap between the tube body and the cap, causing cell contamination. Utility Model Content

[0004] The purpose of this invention is to provide a contamination-resistant cryopreservation tube that can improve the sealing performance of the cryopreservation tube and prevent water or liquid nitrogen from seeping into the cryopreservation tube and contaminating the frozen cells.

[0005] This utility model is achieved through the following technical solution:

[0006] A contamination-resistant cryopreservation tube includes a tube body, a tube cap movably fitted onto the tube body, a protective sleeve provided on the outer wall of the tube body, a protective outer cover movably fitted onto the outer wall of the protective sleeve, the top surface of the protective sleeve contacting the bottom surface of the tube cap, the tube cap being located between the protective outer cover and the protective sleeve, and a floating element slidably fitted onto the outer wall of the tube body, the floating element being located below the protective sleeve.

[0007] Furthermore, an annular sealing groove is provided on the outer wall of the tube, and an annular sealing strip is provided on the inner top surface of the tube cover, the annular sealing strip being adapted to and inserted into the annular sealing groove.

[0008] Furthermore, an identification groove is provided on the outer wall of the tube, and an identification piece is provided in the identification groove.

[0009] Furthermore, a protective shell is provided on the outer wall of the tube, which is used to cover the marking groove.

[0010] Furthermore, the protective sleeve is slidably connected to the pipe body, and the protective sleeve is threadedly connected to the protective outer cover.

[0011] Furthermore, the outer diameter of the floating component is larger than the outer diameter of the protective sleeve.

[0012] Furthermore, a water-absorbing ring is provided at one end of the protective sleeve near the pipe cap, and the pipe cap is provided with a groove corresponding to the water-absorbing ring.

[0013] The technical solution of this utility model has at least the following advantages and beneficial effects:

[0014] This invention uses a protective sleeve and a protective outer cap to seal the connection between the tube cap and the tube body, improving the sealing performance between them and preventing water or liquid ammonia from seeping in through the gaps, thus protecting the cryopreserved cells. By incorporating a floatation element, the cryopreservation tube can be vertically suspended in the water during thawing, with the connection between the tube body and the cap above the water surface. This ensures even heating of the tube, accelerating the thawing process, and also prevents water from entering the tube and causing contamination, further enhancing the cryopreservation tube's airtightness.

[0025] Example 1

[0026] like Figure 1-3 As shown, this embodiment provides a contamination-resistant cryopreservation tube, including a tube body 1, a tube cap 2 movably sleeved on the tube body 1, a protective sleeve 3 provided on the outer wall of the tube body 1, a protective outer cover 4 movably sleeved on the outer wall of the protective sleeve 3, the top surface of the protective sleeve 3 contacting the bottom surface of the tube cap 2, the tube cap 2 being located between the protective outer cover 4 and the protective sleeve 3, and a floating element 5 slidably sleeved on the outer wall of the tube body 1, the floating element 5 being located below the protective sleeve 3.

[0027] The cap 2 is threaded to the tube body 1 to seal the tube body 1 and protect the cryopreserved cells inside. The protective sleeve 3 is connected to the protective outer cap 4 to wrap the connection between the cap 2 and the tube body 1, improving the sealing performance of the connection between the tube body 1 and the cap 2, preventing water or liquid ammonia from seeping in from the gaps between the cap 2 and the tube body 1, and protecting the cryopreserved cells.

[0028] During the thawing of the cryopreservation tube, the float 5 allows the tube body 1 to float vertically in the water, while ensuring that the connection between the tube body 1 and the cap 2 is above the water surface. This ensures that the tube body 1 is heated evenly, accelerating the thawing process, and also prevents water from entering the tube body 1 and causing contamination, thus improving the sealing of the cryopreservation tube. Furthermore, there is no need to clamp or fix the tube body 1 during the thawing process, making the operation flexible and convenient.

[0029] In this embodiment, an annular sealing groove is provided on the outer wall of the pipe body 1, and an annular sealing strip 6 is provided on the inner top surface of the pipe cap 2. The annular sealing strip 6 is adapted to and inserted into the annular sealing groove. The width of the annular sealing groove gradually decreases from top to bottom. The cooperation of the annular sealing groove and the annular sealing strip 6 can improve the sealing performance of the pipe cap 2 to the pipe body 1.

[0030] In this embodiment, an identification groove 8 is provided on the outer wall of the tube 1, and an identification plate is provided in the identification groove 8. The identification plate can identify the name of the frozen cells, which can help staff quickly identify different types of frozen cells and prevent confusion between multiple frozen cells.

[0031] In this embodiment, a protective shell 9 is also provided on the outer wall of the tube body 1. The protective shell 9 is used to cover the marking groove 8. One end of the protective shell 9 is hinged to the inner wall of the marking groove 8, and the other end of the protective shell 9 is snapped into the inner wall of the marking groove 8. The protective shell 9 plays a protective role and can prevent the marking piece from falling off or being damaged by external force.

[0032] In this embodiment, the protective sleeve 3 is slidably connected to the pipe body 1, and the protective sleeve 3 is threadedly connected to the protective outer cover 4. This allows for selective installation of the protective sleeve 3 according to freezing and thawing requirements, making it more convenient.

[0033] In this embodiment, the outer diameter of the float 5 is larger than the outer diameter of the protective sleeve 3. During thawing, the float 5 is tightly attached to the protective sleeve 3, ensuring that the connection between the protective cover 4 and the protective sleeve 3 is also above the water surface, preventing water seepage. After thawing, the float 5 is slid to the bottom of the tube 1, so that the bottom surface of the float 5 is on the same horizontal plane as the bottom surface of the tube 1, increasing the contact area between the tube 1 and the platform, and improving the stability of the cryopreservation tube placed on the platform.

[0034] In this embodiment, a water-absorbing ring 7 is provided at one end of the protective sleeve 3 near the pipe cap 2, and the pipe cap 2 is provided with a groove corresponding to the water-absorbing ring 7. The water-absorbing ring 7 can absorb water that seeps into the space between the protective sleeve 3 and the pipe body 1, preventing water from seeping into the pipe body 1.

[0035] When using cryopreservation, place the cryopreserved cells inside the tube body 1, tighten the tube cap 2, attach the protective sleeve 3 to the outer wall of the tube body 1, slide the protective sleeve 3 until it contacts the tube cap 2, so that the absorbent ring 7 is located in the groove, and tighten the protective outer cap 4.

[0036] When thawing, remove tube 1 from liquid nitrogen, attach float 5 to the outer wall of tube 1, adjust the height of float 5 on tube 1 as needed to suspend tube 1 in water, and then heat the water to thaw.

[0037] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
