Refrigeration storage device for preserving stem cells

Abstract

The invention discloses a refrigeration and cryopreservation device for preserving stem cells. The hanger comprises a supporting seat and a hook rod, a placement box is arranged in the supporting seat; moving wheels are arranged at the lower end of the supporting base, a device body is arranged at the upper end of the supporting base, and an inner shell and liquid nitrogen are arranged in the device body; the liquid nitrogen is arranged between the inner shell and the device body, a controller is arranged on the outer side of the device body, a temperature sensor is arranged on the inner sidewall of the device body, and an early warning signal lamp is arranged at the upper end of the device body. In the refrigeration and cryopreservation device, hanging notches and classification labels are distributed on the supporting plate frame in an annular array mode, wherein hanging notches can be used for hanging and fixing the storage rack; therefore, according to information of stem cell cryopreservation samples stored in different storage racks, information remarks can be made on corresponding classification labels, so that different types of stem cell cryopreservation samples are easily distinguished; in addition, a second thermal insulation layer and a third thermal insulation layer are arranged, and under the action of the second thermal insulation layer and the third thermal insulation layer, cold consumption of liquid nitrogen is reduced.

Description

technical field [0001] The invention relates to the technical field related to stem cells, in particular to a cryopreservation device for storing stem cells. Background technique [0002] Stem cells are a kind of pluripotent cells with self-replication ability. Under certain conditions, stem cells can differentiate into various functional cells. According to the developmental stage of stem cells, they can be divided into embryonic stem cells and adult stem cells. According to the developmental potential of stem cells, they can be divided into: Totipotent stem cells, pluripotent stem cells and unipotent stem cells, with the development of science and technology and medical technology, people have become more and more aware of the importance of stem cells. Stem cells can be used in medicine after collection and processing. In order to maintain the storage effect of stem cells, liquid nitrogen is usually used to refrigerate stem cells. Common cryopreservation devices store the ...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide a cryopreservation device for storing stem cells, to solve the problem that the common cryopreservation devices proposed in the above-mentioned background technology all store the stem cell cryopreservation samples at the mouth of the device, and when the liquid nitrogen in the cryopreservation device When it is insufficient, it is usually necessary to take out the cryopreserved samples of stem cells to facilitate the addition of liquid nitrogen, which is troublesome. Due to the different developmental potential and developmental stages of stem cells, it is necessary to effectively distinguish the cryopreserved stem cells to avoid confusion.
