AI Technical Summary
Technical Problem
Existing stem cell storage devices require manual opening of the refrigeration box when retrieving cells, which causes cold air to escape, affecting storage quality and potentially causing frostbite to the hands.
Method used
A storage device including a storage unit and a refrigeration unit was designed. Liquid nitrogen tanks are used to cool the inside of the storage box through hoses and nozzles, and cell bottles are automatically removed through a screw and turntable mechanism, avoiding direct contact between personnel and the refrigerated box.
Benefits of technology
This technology enables cell culture bottles to be removed without manual intervention, improving storage quality and safety, preventing cold air loss, and ensuring stable storage of cell culture bottles.

Abstract
The utility model provides a storage device for stem cell collection, and relates to the field of stem cell storage, the storage device comprises a storage unit, one side of the storage unit is provided with a refrigeration unit, the storage unit comprises a storage box, and an inner cavity of the storage box is movably connected with a placing cylinder; the pressing plate can be driven to move downwards to be in contact with the cell bottle through the reset elastic force of the spring, then the cell bottle can be positioned, the stability of later storage of the cell bottle is ensured, liquid nitrogen in the liquid nitrogen tank is conveyed to the inner cavity of the hose and the spray head, the liquid nitrogen is conveyed to the interior of the storage box through the spray head, and then the interior of the storage box can be cooled. The rotating disc drives the screw rod to rotate, so that the screw rod drives the sleeve plate to move upwards, the sleeve plate drives the plugging disc, the placing barrel and the cell bottles to move upwards, the placing barrel and the cell bottles are gradually separated from the inner cavity of the storage box, then the cell bottles are conveniently taken out, people do not need to stretch hands into the storage box to take out the cell bottles, and the safety is improved.
