Technical Field

[0001] The utility model relates to the technical field of sample storage, in particular to a freezing box with a cold storage function. Background Art

[0002] Cryoboxes are often used to store and transfer samples in medical research, teaching, and clinical testing. After collecting the experimental samples, they need to be placed in cryotubes and cryoboxes for storage to facilitate subsequent experimental operations and use. When the samples need to be stored or experimentally operated in a low-temperature environment, the cryoboxes are placed in low-temperature storage equipment to achieve the effect of low-temperature preservation.

[0003] In the prior art, after the cryobox is taken out of the low-temperature storage device, it is directly exposed to the external environment. The temperature of the external environment causes the temperature of the sample in the cryobox to rise rapidly until it reaches the temperature of the external environment. Not only can it not ensure that the sample is in a low-temperature environment throughout the process, but also after the sample temperature repeatedly changes over a large span, it will accelerate the deterioration or damage of the sample.

[0030] The cryotube 4 for collecting samples passes through the through hole 201 and is placed in the hole 101;

[0031] The box cover 3 is disposed on the base 1 .

[0032] In the utility model, a plurality of holes for inserting cryogenic tubes are arranged at intervals in the base, and the spaces outside the plurality of holes are connected to form a cavity. The cover plate is matched with the base to cover the cavity to encapsulate the cavity to form a closed empty chamber. The refrigerant is placed in the empty chamber, and the cryogenic tubes are inserted into the holes through the through holes on the cover plate to be preserved at low temperatures by the refrigerant. When the box cover arranged outside the base and the cover plate is removed, any cryogenic tube can be extracted without affecting the normal and continuous freezing of other cryogenic tubes.

[0033] See also Figure 2 and 3 In this embodiment, the base 1 is a box structure without a top cover, the cover plate 2 is a horizontal plate structure, and the cover plate 2 is provided with flange edges 202 along the four sides, and the flange edges 202 match the mouth of the base 1. With this design, the cover plate 2 is horizontally buckled on the top of the base 1, and the flange edges 202 further enhance the tightness of the assembly between the two.

[0034] See also Figure 2-3 In this embodiment, the plurality of holes 101 are evenly arranged in the base 1, and are all in the shape of a cylinder without a cap. The mouth of each hole 101 is flush with the mouth of the base 1, and the plurality of through holes 201 are evenly arranged on the cover plate 2. The aperture of the through hole 201 is consistent with the aperture of the hole 101, and the through hole 201 fits and contacts the mouth of the hole 101. With this design, the cover plate 2 fits and is installed on the top surface of the base 1 to encapsulate the cavity 102, and the empty chamber 5 forms a closed inner cavity structure. The refrigerant is injected into the empty chamber 5, and the plurality of cryotubes 4 inserted into each hole 101 are frozen at the same time.

[0035] See also Figure 1 and 3 In this embodiment, the cryotube 4 is a sealed sample tube, and a tube plug 401 is installed at the tube mouth. The cryotube 4 is inserted into the hole 101, and the tube plug 401 extends outward from the through hole 201. With this design, each cryotube 4 is independently sealed to store samples, reducing the risk of contamination and damage to samples by contamination sources. Each cryotube 4 is inserted into each hole 101 in a one-to-one correspondence, and when any cryotube 4 is extracted from the cover plate 2, the continued freezing of the remaining cryotubes 4 will not be affected.

With this design, when the box cover 3 is covered on the base 1, the cryogenic tube 4 inserted in the base 1 is also covered inside, which plays a role in sealing and protecting the cryogenic tube 4. At the same time, the box cover 3 completely covers the base 1, which plays a role in storing cold and keeping warm the cryogenic agent in the base 1. The cryogenic tube 4 can be taken out by removing the box cover 3.

[0037] See also Figure 1 In this embodiment, the types of the refrigerant are diverse. Designed in this way, the types of the refrigerant include forms, such as solid, liquid, gas, gel and other different refrigerant forms, and also include materials, including water, chemical agents and other materials. The specific types can be selected according to the sample storage requirements. For example, when the refrigerant is selected as water, the cryopreservation box is placed in a low-temperature storage device. When the temperature is as low as 0°C, the water condenses from liquid to ice and becomes solid. After the cryopreservation box is taken out of the low-temperature storage device, when the temperature is higher than 0°C, the ice dissolves from solid to water and becomes liquid. A large amount of cold energy is stored in the freezing process, and a large amount of heat energy is absorbed in the dissolving process, thereby achieving a continuous cold storage and heat preservation effect on the cryopreservation tube 4 taken out from the low-temperature storage device.

[0038] In summary, in the utility model, a refrigerant for low-temperature preservation of cryopreservation tubes is arranged in the base. After the cryopreservation box is taken out from the low-temperature storage device, the refrigerant plays a role in continuously freezing the cryopreservation tubes, ensuring that the samples are kept in low-temperature preservation conditions throughout the process, and avoiding deterioration or damage of the samples due to repeated large-scale temperature changes. Specifically, a plurality of holes for inserting cryopreservation tubes are arranged at intervals in the base, and the spaces outside the plurality of holes are connected to form a cavity. The cover plate is matched with the base cover to encapsulate the cavity to form a closed empty chamber. The refrigerant is placed in the cavity, and the cryopreservation tubes are inserted into the holes through the through holes on the cover plate and are preserved at low temperatures by the refrigerant. The box cover arranged outside the base and the cover plate can be removed to extract any cryopreservation tube without affecting the normal and continuous freezing of other cryopreservation tubes. At the same time, the cryopreservation box has a simple structure, convenient disassembly and assembly, easy implementation and use, low manufacturing cost, and good promotion prospect.
