Description

Technical Field

[0001] The utility model relates to the technical field of cell freezing bottles, in particular to a stem cell freezing bottle. Background Art

[0002] Cell cryopreservation is a technique that places cells in a low-temperature environment to reduce cell metabolism for long-term storage. Cell cryopreservation is one of the main methods of cell preservation and plays a role in cell seed preservation. Using cryopreservation technology to store cells in -196℃ liquid nitrogen can temporarily remove cells from the growth state and preserve their cell characteristics.

[0003] Existing stem cell cryovials usually use a threaded structure to achieve a sealing function, but the sealing between the tube cap and the tube body of the cell cryovial in the prior art is difficult to ensure. When the tube cap is accidentally rotated, the sealing ring is easily separated from the outer tube, which may easily lead to leakage of the cryopreservation tube. Utility Model Content

[0004] The purpose of the utility model is to provide a stem cell freezing bottle, which is used to overcome the above-mentioned defects in the prior art.

[0005] According to the utility model, a stem cell freezing bottle includes a cryopreservation tube, a threaded sleeve is fixedly provided on the outer circumference of the cryopreservation tube, a sealing cylinder is provided at the upper end of the cryopreservation tube, a rotating cover is rotatably connected to the upper end surface of the sealing cylinder, the cross-section of the sealing cylinder is L-shaped, the inner and outer ends of the threaded sleeve and the inner end of the sealing cylinder are provided with two threaded grooves of different heights, the sealing cylinder is provided with a sealing gasket near the end of the cryopreservation tube, the sealing gasket is tightly attached to the threaded sleeve, a sliding groove is opened in the sealing cylinder, a sliding latch that can slide up and down is provided in the sliding groove, a push spring is connected between the sliding latch and the lower side wall of the sliding groove, the upper end of the cryopreservation tube is opened with circumferentially evenly distributed limit slots, the The sealing gasket is provided with two inner and outer circles fixedly arranged on the sealing cylinder, an annular through cavity is provided between the inner and outer sealing cylinders and is arranged correspondingly to the limit card groove up and down, the rotating cover plate is provided with a large cavity and a small cavity which are opened up and down and evenly distributed circumferentially, the large cavity and the small cavity are staggered circumferentially, each of the small cavity is fixedly provided with an upper limit cover, each of the large cavity is fixedly provided with a lower limit cover, the upper limit cover and the lower limit cover are staggered up and down, the front end of the freezing tube and the sealing cylinder are fixedly provided with a positioning block, the upper end of the rotating cover plate is fixedly provided with an annular holding sleeve, the upper end of the sliding latch is provided with an arc block, the upper limit cover, the arc block and the lower limit cover are all provided with coatings of different colors.

[0006] The beneficial effects of the utility model are:

[0007] The arc block on the sliding latch abuts against the upper limit cover and the lower limit cover that are staggered circumferentially, so that the user can obtain information on whether the sliding latch is inserted into the limit slot, thereby quickly completing the limiting work of the sliding latch on the limit slot without the need for manual detection by the user, and the structure is simple, convenient and fast.

[0008] By arranging coatings of different colors on the upper ends of the upper limit cover and the lower limit cover and arranging different radii of the small cavity and the large cavity, it can further help the user to identify the working status and achieve the working effect.

[0009] By rotating the cover plate to control the up and down movement of the sliding pin, it is controlled whether the sliding pin is inserted into the limiting slot to complete the limiting function at the sealing cylinder, thereby reducing the possibility of the sealing cylinder automatically rotating and affecting the sealing effect of the sealing gasket, thereby facilitating reducing the possibility of leakage of the cryopreservation tube.

[0022] The user stores stem cells and stem cell culture fluid in the cryopreservation tube 10;

[0023] First, the user uses the two alignment blocks 26 set up above and below to make the cryopreservation tube 10 and the sealing tube 12 correspond to each other up and down through the alignment blocks 26, and places the sealing tube 12 on the upper end of the cryopreservation tube 10 so that the sealing tube 12 and the threaded sleeve 11 are abutted inside and outside. The user rotates the sealing tube 12 so that the sealing tube 12 and the threaded groove 14 at the outer end of the threaded sleeve 11 are first abutted, and the sealing tube 12 rotates downward during rotation under the thread cooperation of the threaded groove 14. The user holds the sealing tube 12 and rotates it, and adjusts the rotating cover plate 13 downward on the threaded sleeve 11, and then makes the threaded sleeve 11 and the threaded groove 14 at the inner end of the sealing tube 12 threadedly connected, so that the sealing tube 12 rotates downward and abuts against the outer protruding end of the threaded sleeve 11 and then stops. At this time, the two sealing gaskets 20 set inside and outside and fixed in the sealing tube 12 are tightly attached to the upper end surface of the cryopreservation tube 10 for sealing;

[0024] When taking the product, the user rotates the rotating cover plate 13 by holding the holding sleeve 24, so that the rotating cover plate 13 rotates on the upper end of the sealing cylinder 12. Figure 5 As shown, when the sliding latch 16 moves downwards and abuts against the upper limit cover 15 by the spring force of the push spring 19, the user can judge by observing whether the position of the arc block 17 is located at the upper limit cover 15. If the upper limit cover 15 and the arc block 17 are in the same position, the sliding latch 16 is located above the limit slot 21 and does not abut against the side wall of the limit slot 21. At this time, the user can rotate the sealing cylinder 12 to remove the sealing cylinder 12 from the threaded sleeve 11;

[0025] On the contrary, when storing, the upper limit cover 15 and the lower limit cover 23 are in the same position, and the arc block 17 is pressed by the lower limit cover 23. Figure 5 The sliding latch 16 shown slides downward to overcome the spring force at the push spring 19, so that the lower end of the sliding latch 16 is inserted into the limit slot 21, so that the circumferential limit between the sealing cylinder 12 and the freezing tube 10 is completed. At this time, the user can judge whether the limit work is completed by observing whether the positions of the upper limit cover 15 and the lower limit cover 23 are consistent. The sliding latch 16 engages the side wall of the limit slot 21 to limit the circumferential rotation of the sealing cylinder 12, so that the sealing cylinder 12 cannot be rotated circumferentially and removed from the threaded sleeve 11.

[0026] It is clear to those skilled in the art that various modifications to the above embodiments can be made without departing from the overall spirit and concept of the present invention. All of them fall within the protection scope of the present invention. The protection scheme of the present invention shall be subject to the claims attached to the present invention.
