Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of cell storage, and in particular relates to a cell storage device with a high mechanical sealing structure. Background Art
[0002] After cells are separated and cultured from human tissues, and then undergo testing, identification, and related processes, most of them are stored at low temperatures to maintain their activity so that they can be activated and used later according to the actual needs of the patient, and to facilitate related experimental research. In cell storage devices, due to the low temperature requirements of the storage environment and the limitation of storage time, the quality of its sealing determines the frequency of later low-temperature replenishment and the storage effect on cells. Most common cell storage devices open and close a large area before and after sampling, resulting in a large amount of cold air loss during the sampling process, which in turn affects the cooling effect of the device and increases the frequency of cold air replenishment. Moreover, due to the single sealing of the connection, cold air is continuously lost from the gaps during static storage, which also affects the cooling effect of the device and increases the frequency of cold air replenishment, resulting in inconvenience in cell storage.
