[0025] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0026] like Figures 1-5As shown, an expandable specimen cryopreservation box includes a first cryopreservation box 1, a second cryopreservation box 2, a snap fastener 3, a cold preservation mechanism 4, a temperature detection system 5, and a QR code etching machine 6. The bottom of the first cryopreservation box 1 is detachably mounted to the top of a second cryopreservation box 2, and the bottom of the second cryopreservation box 2 is detachably mounted to the top of the other second cryopreservation box 2. The first cryopreservation box 1 includes a first lid 11 and a first body 12. The first lid 11 includes a first lid body 111 and a handle 112. Two handles 112 are hinged to the top surface of the first lid body 111, and the two handles 112 are symmetrically arranged. The bottom of the first body 12 is symmetrically provided with double L-shaped slots 121. The first lid body 111 is detachably mounted to the first body 12 via the snap fastener 3. The second cryopreservation box 2 includes a second lid 21 and a second body 22. The second lid 21 includes a second lid body 211 and a T-shaped protrusion 212. The top of the second lid body 211... Two T-shaped protrusions 212 are symmetrically installed on the surface. The second box body 22 has the same structure as the first box body 12. The second box cover body 211 is detachably installed onto the second box body 22 via a buckle 3. One of the T-shaped protrusions 212 is detachably installed into a double L-shaped slot 121. The cold preservation mechanism 4 is placed inside the first box body 12 and the second box body 22. The temperature detection system is installed on the first box body 12 and the second box body 22. The QR code etching machine 6 is installed on the outer wall of the first box body 12 and the second box body 22. The first cryopreservation box 1 and the second cryopreservation box 2 are made of medical-grade polypropylene (Grade VI) material, which is resistant to ultraviolet light, alcohol and ethylene oxide sterilization. The stacked installation of the first cryopreservation box 1 and the second cryopreservation box 2 increases portability and practicality. The cold preservation mechanism 4 increases the cold preservation performance. The temperature detection system 5 can effectively detect the temperature inside the cryopreservation box to prevent the specimen from being damaged by temperature. The QR code etching machine 6 can accurately mark and count the specimen, thereby increasing the accuracy of the experiment.
[0027] The second lid body 211 has the same structure as the first lid body 111. The second lid body 211 has symmetrical scales 2111 on both sides and anti-slip grooves 2112 on the other two sides. The anti-slip grooves 2112 provide a point of force to effectively prevent slipping during handling.
[0028] The second box lid body 211 has a first protruding ridge on each of its four sides, and the second box body 22 has a second protruding ridge on each of its four sides. The first protruding ridge abuts against the second protruding ridge, and the first and second protruding ridges are symmetrically arranged. The buckle 3 is slidably connected to the first and second protruding ridges. Each of the first and second protruding ridges has an elastic limiting ring on each side. The outer wall of the second box body 22 has a frosted handwriting area. The elastic limiting ring effectively prevents the buckle 3 from falling off due to excessive external force, thereby increasing the sealing of the first cryopreservation box 1 and the second cryopreservation box 2. The buckle 3, in conjunction with the scale 2111, can not only play a fixing role, but also a physical counting role. The frosted handwriting area can be used for specimen annotation.
[0029] The cold preservation mechanism 4 includes a tube rack 41 and a plurality of cryopreservation tubes 42. The tube rack 41 has a plurality of tube holes and a double-layer structure inside, which is filled with cold preservation material. Each cryopreservation tube 42 is placed in one of the tube holes. The double-layer structure can reduce temperature fluctuations and ensure temperature stability. The cold preservation material is water and a high-molecular water-retaining agent, such as polyvinyl alcohol and polyacrylamide, which can be repeatedly frozen and reused. The tube rack 41 can be configured with various specifications, such as 10×10 tube holes, which can hold 1.5ml, 1.8ml, and 2ml cryopreservation tubes 42, or 8×8 tube holes, which can hold 2.0ml, 5.0ml, and 7ml cryopreservation tubes 42.
[0030] The temperature detection system 5 includes a controller 51, an alarm light 52, and a temperature sensor 53. The temperature sensor 53 is installed inside the first box 12 and the second box 22. The controller 51 is installed on the outer wall of the first box 12 and the second box 22. The alarm light 52 is installed on the outer wall of the first box 12 and the second box 22. The temperature sensor 53 is electrically connected to the controller 51, and the controller 51 is electrically connected to the alarm light 52. The temperature sensor detects the temperature inside the cryopreservation box and transmits the detection data to the controller 51. When the temperature is within acceptable limits, the alarm light 52 is off. When the temperature is outside acceptable limits, the controller 51 controls the alarm light 52 to turn on. The acceptable temperature inside the first cryopreservation box 1 and the second cryopreservation box 2 is -20℃ to 4℃, and the single cold preservation time is ≥8h.
[0031] When this utility model is in operation: Prepare the first cryopreservation box 1 and the second cryopreservation box 2. The staff places the specimens into cryopreservation tubes 42 of appropriate capacity, attaches stickers to the outer wall of the cryopreservation tubes 42 and aligns them with the QR code etching machine 6 to etch QR codes for marking. Then, place the cryopreservation tubes 42 into the tube holes of the tube rack 41. After all the tubes are placed, the first box cover 11 and the second box cover 21 are tightly installed onto the first box body 12 and the second box body 22 respectively by the buckles 3. Adjust the buckles 3 on both sides of the scale 2111. Record the total number of specimens by the combination of the buckle 3 positions. For example, if the buckle 3 position on one side is scale "2" and the buckle 3 position on the other side is scale "7", it means "27" specimens. Then, connect the first cryopreservation box 1 and the second cryopreservation box 2 through the double L-shaped slots 121 and the T-shaped protrusions 212. The box can be quickly transported by the handle 112.
