Description

Technical Field

[0001] The utility model relates to the technical field of cell storage, and more particularly to a cell freezing storage device. Background Art

[0002] Cells are the fundamental structural and functional units of living organisms. All organisms, except viruses, are known to be composed of cells. However, viruses must also function within cells. To prolong cell life and maintain cell activity, cells must be cryopreserved. Liquid nitrogen freezers are commonly used to freeze cell tubes.

[0003] A cell freezing storage device with announcement number CN221499036U includes: a storage tank, a culture dish rack, five fixed slots, cell culture dishes, and a lifting mechanism; the culture dish rack is arranged inside the storage tank through the lifting mechanism to provide support for the cell culture dishes when they are stored; the fixed tube is fixedly connected to the bottom inner wall of the storage tank, and the bottom end of the insertion rod slides through the inside of the fixed tube. The top cover is rotated by rotating the handle, and the rotation of the top cover drives the culture dish rack and the cell culture dishes to the top of the storage tank, thereby facilitating the removal of the cell culture dishes, and the staff no longer need to reach into the storage tank, avoiding frostbite of the hands by liquid nitrogen.

[0004] In actual use, the cell freezing storage device proposed in the above patent document utilizes the rebound force of the spring to drive the culture dish rack as a whole to move upward. However, the spring is prone to fatigue after long-term compression and use, thus affecting the rebound force. In addition, the structure cannot independently lift the fixed groove on the surface of the culture dish rack. Therefore, each time a cell test tube is taken out and placed, each test tube will be lifted to the outside of the fixed plate, affecting the freezing preservation effect of the cells.
