Description

Technical Field

[0001] The utility model relates to the technical field of stem cell cooling, in particular to a cooling device used in the process of stem cell freezing. Background Art

[0002] As we all know, stem cell preservation is a process of freezing stem cells in order to preserve their activity and potential for a long time. Stem cells are a type of primitive cells with self-renewal ability and multidirectional differentiation potential. They can differentiate into various types of cells or tissues and organs. The preservation of stem cells usually involves special cryopreservation techniques, which include the use of liquid nitrogen to keep stem cells in a dormant state. The life activities in the cells are almost stopped, so that the long-term preservation of stem cells can be achieved. Current technology shows that stem cells can be preserved for a long time, even more than a century, and the preserved stem cells still have activity and potential for clinical application.

[0003] After searching, the utility model patent with Chinese publication number CN208940797U discloses a cooling device used in the process of stem cell cryopreservation, which includes a heat-insulating outer shell, a protective shell, and a fixed frame. A heat exchange pipe is arranged on the inner side of the heat-insulating outer shell, and a heat-conducting inner shell is arranged on the side of the heat-exchange pipe away from the heat-insulating outer shell. The fixed frame is arranged inside the heat-conducting inner shell, and a fixing plate is arranged inside the fixed frame. A fixing through hole is arranged on the fixing plate, and a protective pad is arranged below the fixing plate. An elastic heat-insulating block is arranged above the fixed frame, and a rotating shaft is arranged below the fixed frame. A supporting slider is arranged on the side of the rotating shaft, and a temperature sensor is arranged between the supporting slider and the rotating shaft. The beneficial effect is that the utility model can automatically drive the fixed frame to rotate, thereby rotating the stem cell container in the fixed frame, so that the stem cells and the freezing solution are evenly mixed. It is simple and convenient to use, and the mixing effect is improved.

[0004] In the above technical solution, the container storing stem cells can only be rotated in place, but the container cannot be rotated backwards, which may cause the stem cells and the freezing solution to be unevenly mixed, resulting in a significant reduction in the storage time of the stem cells and causing great inconvenience to the staff during storage. Therefore, a cooling device is needed for use in the freezing process of stem cells. Utility Model Content
