Description

Technical Field

[0001] This utility model relates to the field of stem cell preservation technology, specifically a cooling device for stem cell cryopreservation. Background Technology

[0002] Stem cells are a type of cell with unlimited or immortal self-renewal capacity, capable of producing at least one type of highly differentiated daughter cells. The definition of stem cells has been continuously revised over the years and defined from different perspectives. Most biologists and medical professionals believe that stem cells are a type of cell derived from embryos, fetuses, or adults, possessing the ability to self-renew, proliferate, and differentiate without limitation under certain conditions. They can produce daughter cells with identical phenotypes and genotypes, as well as specialized cells that make up body tissues and organs, and can differentiate into progenitor cells. Cryopreservation is necessary for stem cell preservation to ensure their integrity. While existing cryopreservation devices are mobile, they are prone to displacement during use, potentially causing impacts that could damage the preserved stem cells. Utility Model Content

[0003] The purpose of this invention is to provide a cooling device for stem cell cryopreservation, which solves the problem that although existing stem cell cryopreservation cooling devices are mobile, they are prone to displacement during parking and use, which can cause the cooling device to be impacted and affect the stem cells stored inside.

[0004] Technical solution

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cooling device for stem cell cryopreservation, comprising a tank, a support plate at the bottom of the tank, a groove on the upper surface of the support plate, the bottom of the tank engaging with the inside of the groove, a handle fixedly connected to the outer surface of the tank, casters fixedly connected to the lower surface of the support plate, an assembly groove on the upper surface of the support plate, a retaining plate inserted into the assembly groove, the right side of the retaining plate being fixedly connected to the left side of the tank, an installation groove on the left side of the retaining plate, a supporting rod inserted into the installation groove, a sliding groove on the upper surface of the support plate, a slider slidably connected inside the sliding groove, and the upper surface of the slider being fixedly connected to the lower surface of the supporting rod.

[0006] Furthermore, a spring is fixedly connected to the left side of the slider, and the left end of the spring is fixedly connected to the left inner wall of the slide groove.

[0007] Furthermore, the lower surface of the abutment rod overlaps with the upper surface of the support plate.

[0008] Furthermore, the number of the card plates is two, and the two card plates are symmetrically arranged about the central axis of the tray.

[0009] This invention provides a cooling device for stem cell cryopreservation. It has the following beneficial effects:

[0010] This cooling device for stem cell cryopreservation, through the combination of a tray, a groove, casters, a clamping plate, an assembly groove, an installation groove, a supporting rod, a spring, a sliding groove, and a slider, facilitates the transfer of the cooling device while also allowing it to be lifted and separated from the moving parts. This prevents displacement when placed on the ground, solving the problem that while existing stem cell cryopreservation cooling devices are mobile, they are prone to displacement during use, causing impacts that could affect the preserved stem cells inside.
