Description

Technical Field

[0001] The utility model relates to the technical field of storage boxes, in particular to a stem cell storage box which is convenient for taking and placing. Background Art

[0002] Stem cells are a type of cell that has unlimited or immortal self-renewal ability and can produce at least one type of highly differentiated daughter cells. They can differentiate into a variety of functional cells. According to the developmental stage of stem cells, they are divided into embryonic stem cells and adult stem cells. According to the developmental potential of stem cells, they are divided into three categories: totipotent stem cells, pluripotent stem cells and unipotent stem cells. Stem cells are not fully differentiated and immature cells, and have the potential to regenerate various tissues, organs and the human body.

[0003] When stem cells are cultured experimentally, they are mostly stored in 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 solution proposes a stem cell storage box that is easy to take and put. Utility Model Content
