Description

Technical Field

[0001] The utility model relates to the technical field of biological product storage equipment, in particular to a multi-layer refrigeration device for stem cell storage. Background Art

[0002] Stem cells are a type of multipotent cells with the ability to self-renew. They are not fully differentiated and immature cells that have the potential to regenerate various tissues, organs and the human body. The medical community calls them "universal cells". After stem cells are separated and cultured from different human tissues, they are tested and identified, and then frozen at a deep low temperature of -196°C so that they can be revived and re-infused into patients when clinically needed, in order to achieve the purpose of treating the disease.

[0003] When stem cells are cultured experimentally, they are mostly stored in refrigerated boxes for easy transportation and movement. Since stem cells need to be stored under certain low temperature conditions, currently available storage boxes either have refrigeration mechanisms inside, or when storing stem cell test tubes, the boxes are filled with cold air or ice packs are placed in them.

[0004] When using stem cell test tubes, laboratory staff generally do not take out all of them, but take out the corresponding test tubes for experiments as needed. Whether it is a storage box with a refrigeration mechanism or a storage box filled with cold air and ice packs, the cold air will be lost when the box lid is opened. In addition, the staff needs to confirm the test tube before taking it, which prolongs the opening time of the box lid, resulting in a large loss of cold air. If the cold air is not replenished in time, the temperature rise will have a certain impact on the remaining stem cell test tube culture. If the user speeds up the operation in order to maintain the temperature in the box, it is easy to make mistakes, which is not conducive to taking and placing the test tubes.

[0005] Based on this, this scheme proposes a multi-layer refrigeration device for stem cell storage. Utility Model Content
