Description

Technical Field

[0001] The utility model relates to the technical field of cell storage, in particular to a stem cell storage tank. Background Art

[0002] A stem cell storage tank is a device specifically used to preserve and store stem cells. It is commonly used in the medical field, especially in cell therapy, regenerative medicine and biomedical research. The main function of a stem cell storage tank is to provide a safe and stable environment to maintain the activity and quality of stem cells and ensure that they can function effectively when needed. The stem cell storage tank can preserve stem cells for a long time in a low-temperature environment to prevent cell aging and death, ensuring that they still have good functions when used in the future. After the stem cells are processed, they are placed in -196°C liquid nitrogen inside the storage tank and stored at the low temperature of liquid nitrogen. This process usually uses cryoprotectants to reduce damage to cells during the freezing process. Since the storage tank needs to be opened and closed during the placement and removal of stem cells, it is necessary to separate the lid of the storage tank.

[0003] In the related art, when a storage tank is used, a staff member generally opens the locking cover on the top of the storage tank by holding it, and then separates the cover plug on the top of the storage tank by holding it, and completely opens the opening of the storage tank for use.

[0004] However, when the storage tank is currently in use, the lid plug needs to be completely separated from the storage tank during the opening process, and the storage tank itself cannot support the separated lid plug, which makes it inconvenient to operate after the lid plug of the storage tank is separated, affecting the convenience and support effect of the opening and closing operation of the storage tank.
