Description

Technical Field

[0001] The utility model relates to the technical field of stem cell cryopreservation tubes, in particular to an explosion-proof device for stem cell cryopreservation tubes. Background Art

[0002] When thawing the stem cell cryopreservation tube, it needs to be taken out of the liquid nitrogen tank and placed in a -80°C refrigerator for a short period of time to allow the liquid nitrogen to evaporate. The stem cell cryopreservation tube is then placed in a water bath for water bath thawing.

[0003] After searching, the utility model patent with Chinese patent publication (announcement) number CN217337188U discloses an explosion-proof device for stem cell cryopreservation tubes, which is roughly described as comprising a protective shell and a protective cover, wherein a plurality of placement slots are arranged in the protective shell, and a cavity is arranged at the lower end of the protective shell. When in use, the protective cover is buckled on the top of the protective shell, and each protective plug is aligned with a stem cell cryopreservation tube in a placement slot. During the downward movement of the protective cover, the inclined opening at the lower end of the pressure relief tube is used to make the pressure relief tube penetrate the tube cover and be inserted into the stem cell cryopreservation tube. Therefore, when the stem cell cryopreservation tube is revived in a water bath, the liquid nitrogen infiltrated into the stem cell cryopreservation tube will be rapidly vaporized, so that the inside of the stem cell cryopreservation tube is The air pressure rises. At this time, under the action of pressure, the gas in the stem cell cryopreservation tube passes through the pressure relief pipe and enters the pressure relief chamber in the protective plug, and pushes the sealing ball and the sliding cylinder in the pressure relief chamber to move upward. The gas is quickly discharged through the pressure relief chamber and the exhaust slot, thereby achieving rapid pressure relief inside the stem cell cryopreservation tube, and effectively reducing the probability of the stem cell cryopreservation tube exploding due to the rapid gasification of liquid nitrogen in the stem cell cryopreservation tube, thereby achieving explosion-proof of the stem cell cryopreservation tube and improving the safety of the use of the utility model. However, the above-mentioned device still has certain shortcomings. For example, the above-mentioned device has great limitations, is not convenient for application to cryopreservation tubes of different specifications, and has poor applicability. For this reason, we propose a stem cell cryopreservation tube explosion-proof device. Utility Model Content

[0027] exist Figure 1-Figure 5In the embodiment, a placement mechanism is arranged in a shell 2, and the placement mechanism includes a fixing ring 3 and a support plate 4. The fixing ring 3 is fixedly connected in the shell 2, and the support plate 4 is located in the shell 2. Two fixing blocks 5 are fixedly connected through the support plate 4, and two circular grooves are provided on the fixing block 5. Two slide grooves 1 are provided in the circular groove, and a slider 6 is slidably connected in the slide groove 1. A plurality of springs 7 are provided between the slider 1 6 and the slide groove 1, and a clamping plate 8 is fixedly connected to the slider 1 6. A plurality of openings 2 9 and a plurality of limiting grooves 10 are provided on the fixing block 5, and a bottom plate 11 is provided in the circular groove, and a connecting plate 12 is fixedly connected to the bottom plate 11, and the connecting plate 12 passes through the circular groove through the adjustment port. A lifting rod 13 is fixedly connected between the four connecting plates 12, and two slide grooves 2 are provided on the lifting rod 13. A slider 2 14 is slidably connected in the slide groove 2, and a tension spring 15 is arranged between the slide groove 2 and the slider 2 14. A limiting plate 16 is fixedly connected to the slider 2 14, and two limiting blocks 17 are fixedly connected to the limiting plate 16. The limiting block 17 is located in one of the limiting grooves 10. The splint 8, the slider, the spring 7, the lifting rod 13, the bottom plate 11, etc. are used to place cryopreservation tubes of different thicknesses and heights, thereby improving the practicability of the overall device. When the liquid nitrogen attached to the outer wall of the cryopreservation tube volatilizes due to the increase in temperature, it can be volatilized through the opening 1 and the opening 2 9.

[0028] exist Figure 3 and Figure 5 In the figure, a partition 18 is fixedly connected to the support plate 4, and the lifting rod 13 is slidably connected to the partition 18 for shielding, thereby preventing the freezing tube from affecting other freezing tubes when the freezing tube explodes.

[0029] exist Figure 2 and Figure 4 In the embodiment, a cushion 19 is fixedly connected to the clamping plate 8 to play a protective role.

[0030] exist Figure 2 In the figure, a soft pad 20 is fixedly connected to the bottom plate 11 to play a protective role.

[0032] In summary, the working principle and working process of the stem cell cryopreservation tube explosion-proof device are as follows: when in use, the stem cell cryopreservation tube explosion-proof device is first placed at the desired location, and then when adjustment is needed, people can first adjust the position of the pressure plate according to the length of the cryopreservation tube, and people can take out the support plate 4, the fixing block 5, etc. through the handle 21, and then use both hands to pull the limit plate 16. At this time, the limit plate 16 drives the slider 14 to stretch the tension spring 15, so as to drive the limit block 17 to move out of the limit groove 10. After the limit groove 10 is no longer limited to the limit block 17, people can adjust the height of the lifting rod 13. The lifting rod 13 will drive the connecting plate 12 and the bottom plate 11 to adjust their positions. After the adjustment, the limit plate 16 is released, and the tension spring 15 contracts and rebounds to drive the slider 14, the limit plate 16 and the limit block 17 to move, so that the limit block 17 can enter other limit grooves 10, thereby facilitating the limitation of the lifting rod 13, the bottom plate 11, etc., and then people put the cryogenic tube into the circular groove. At this time, because of the slider and the spring 7, the clamp 8 will clamp the cryogenic tube to ensure the stability of the cryogenic tube. Then people put the support plate 4, the fixing block 5, etc. into the outer shell 2 and cover the pressure relief mechanism 1.

[0033] The pressure relief mechanism 1 involved in this scheme is an authorized technology disclosed in the utility model patent with Chinese patent publication (announcement) number CN217337188U. Its internal structure and working principle are well known to those skilled in the art and are not the innovation of this patent.
