Description

Technical Field

[0001] The utility model relates to the technical field of low-temperature storage devices, in particular to a low-temperature storage device with a stable structure. Background Art

[0002] Stem cells are special cells with the ability to self-replicate and differentiate. They can develop into various cell types through different differentiation pathways and have important medical and scientific research value. After stem cells are extracted, they need to be stored in an extremely low temperature environment to prolong the survival time of stem cells. Therefore, a low-temperature preservation device for stem cells is needed. However, when the existing low-temperature preservation device is in use, the internal protective structure of the buffer support is lacking, resulting in unnecessary damage or denaturation of the stem cells stored inside when the device is subjected to external impact. In addition, the internal storage tube is mostly a fixed structure. After long-term storage, stem cells are prone to precipitation and agglomeration in a low-temperature environment, which is not conducive to later use and research, thereby affecting their preservation quality and vitality. Therefore, it is urgent to set up a low-temperature preservation device with a stable protective structure to improve the internal structural strength, effectively prevent the influence of external impact on the internal stem cells, and prevent unnecessary damage to the stem cells. A structure that allows the storage tube to rotate is added to prevent the internal stem cells from precipitation and agglomeration. Utility Model Content

[0012] Beneficial effects of the utility model:

[0013] 1. During the use of the existing cryopreservation device, there is a lack of a buffer support protection structure inside, which causes unnecessary damage or denaturation of the stem cells stored inside the device when the device is subjected to external impact. In addition, the internal storage tube is mostly a fixed structure. After long-term storage, the stem cells are prone to precipitation and agglomeration in a low-temperature environment, which is not conducive to later use and research, thereby affecting their preservation quality and vitality. Therefore, the internal buffer stabilization component can provide additional support force to absorb the energy of external impact or vibration to prevent the device from being deformed or broken due to external force or vibration during storage, keep the stem cells in the storage barrel in a stable state, and prevent the stem cells from being damaged. The internal rotation adjustment component can use rotation to continuously maintain the cell suspension state and prevent the occurrence of cell precipitation and agglomeration. The continuous and stable rotation can provide a more stable and uniform low-temperature environment, thereby maximizing the survival rate and preservation effect of the cells.

[0014] 2. Adjusting the buffer spring inside the groove can make the protective support plate have an elastic range of movement. When impacted by the outside world, the shaking of the stem cell storage inner cylinder is transmitted to the protective support plate; cooperate with the transmission support plate to make the pressure-bearing sliding block squeeze against the buffer spring, which has the effect of dispersing the vibration impact force, plays a role in supporting and protecting the stem cell storage inner cylinder, and makes the internal structure of the device stable;

[0015] 3. The first driving motor can drive the transmission rotating rod to rotate, thereby rotating the rotating turntable, and the rotating turntable rotates the driving latch gear. When the driven concave tooth groove at the lower end of the stem cell storage inner cylinder contacts the driving latch gear, the stem cell storage inner cylinder can rotate. The second driving motor can drive the adjusting screw to rotate, thereby causing the external limiting movable sleeve to move up and down. The limiting movable sleeve drives the supporting connecting plate to move synchronously, so that the lifting frame bottom plate can lift the stem cell storage inner cylinder to a high degree, making it convenient to take out the stem cells stored inside, reducing the risk of accidents caused by improper human operation, and ensuring the safe storage and use of stem cells.
