Description

Technical Field

[0001] The utility model relates to the technical field of biological equipment, in particular to a umbilical cord blood cooling box. Background Art

[0002] Umbilical cord blood needs to be cooled before being put into liquid nitrogen tank. Currently, this is mainly done by using an automatic program cooling instrument to place the umbilical cord blood cryopreservation box in the instrument, setting the program for program cooling, and only after reaching a certain temperature can it be cryopreserved in -196℃ liquid nitrogen. This can temporarily remove the cells from the growth state and preserve their cell characteristics, so that the cells can be revived for experiments when needed. However, the cooling device used by the currently used program cooling instrument has the following problems:

[0003] 1. The program cooling operation is limited by the instrument, and the function is single and the operation is complicated. It takes a long time to achieve program cooling, and the corresponding data can only be obtained after the cooling program is completed;

[0004] 2. At present, the instrument used for cooling program needs to be connected to liquid nitrogen before it can be used. The demand for liquid nitrogen is high and the cost of liquid nitrogen is relatively expensive. After the program is cooled, it must be closed immediately, otherwise the liquid nitrogen will be consumed continuously, which is costly.

[0005] 3. There is a certain degree of danger when using liquid nitrogen, and it is very easy to cause danger if the operation is not careful.

[0006] Therefore, a cord blood cooling box that is simple to use and easy to operate is used to overcome the above problems and defects. Utility Model Content

[0007] The purpose of the utility model is to provide an umbilical cord blood cooling box, which abandons the limitation of the existing automatic program cooling instrument. After using the umbilical cord blood cooling box provided by the present application, there is no need to use an instrument for data tracking, and the data anomaly problem caused by the lack of liquid nitrogen can be solved. The umbilical cord blood box is placed in the cooling box, and isopropyl alcohol is placed in the cooling box at the same time. Then, after the iron box containing the umbilical cord blood freezing bag is placed inside the inner liner, the temperature is slowly cooled in a refrigerator at -80 degrees Celsius by utilizing the large specific volume heat of isopropyl alcohol. After reaching this temperature (-80°C), it can be concentrated into a liquid nitrogen tank again as needed for longer storage, without the need to connect liquid nitrogen cooling in the early cooling stage. When cooling, ordinary protective gloves can be worn. Therefore, it can be used to solve the defects of the existing umbilical cord blood program cooling box, such as single function, poor flexibility of use, cumbersome steps and low safety.

[0008] In order to solve the above technical problems, the utility model provides the following technical solutions:

At this time, the isolation plate is placed inside the box body through the handle, and the isolation plate and the inner support plate are attached to each other. Under the action of the cotton sheet, the volatilization of isopropyl alcohol is reduced, thereby improving the convenience of the cord blood cooling box when in use; isopropyl alcohol has the characteristic of large specific heat capacity, and the device is placed in a refrigerator at -80℃, relying on the action of isopropyl alcohol to achieve slow cooling. And under the condition of reaching -80℃, it can be kept for a certain period of time, so different batches of cord blood boxes can be put into the liquid nitrogen tank again for longer storage as needed, which not only fully reduces the dependence on liquid nitrogen, but also solves the use problems caused by insufficient liquid nitrogen tanks.

[0023] By providing a sealing structure and rotating the cover body, the top of the box body is fixedly connected to the cover body under the meshing action of the thread. At this time, the bottom end of the cover body contacts the top end of the sealing gasket, and the top end of the sealing ring moves to the inside of the sealing groove, so that the top end of the box body is sealed with the cover body through the sealing ring, thereby enhancing the sealing performance of the device and improving the safety of the umbilical cord blood cooling box when in use.
