Description

Technical Field

[0001] The utility model is applicable to the technical field of stem cell preservation, and particularly relates to a stem cell preservation device. Background Art

[0002] At present, stem cells are a type of cells with unlimited or immortal self-renewal capabilities. In terms of preservation, stem cells need to be stored in liquid nitrogen. Due to the particularity of liquid nitrogen, the temperature in liquid nitrogen will be very low. At the same time, stem cells will enter a dormant state in a low-temperature environment and can be preserved indefinitely.

[0003] However, when storing stem cells nowadays, they are often placed in a test tube with a culture medium, and then placed in a liquid nitrogen box for refrigeration. When inserting the test tube, it is only fixed by the friction provided by the diameter of the inner side of the placement groove fitting against the outer side of the test tube. Once the test tube is too large or too low, the test tube cannot be reinforced and it is easy to cause shaking and collision when moving, affecting the storage quality of the test tube. Therefore, we propose a stem cell storage device. Utility Model Content

[0010] As an optional solution of the technical solution of the present application, movable grooves are opened inside both ends of the side of the fixed plate, and the transmission frame, connecting plate, transmission rod and connecting rod are all movably installed inside the movable grooves.

[0011] By adopting the above technical solution, the rationality of transmission adjustment of the entire device is ensured by the guiding sliding action of the movable groove on the transmission frame, the connecting plate, the transmission rod and the connecting rod.

[0012] As an optional solution of the technical solution of the present application, a fitting arc plate is fixedly installed on the surface of one end of the inner wall of each placement groove away from the movable arc plate.

[0013] By adopting the above technical solution, the fit of the arc plate to the outside of the reagent tube is ensured by the structural effect of the arc plate.
