Full-automatic low-temperature storage equipment for stem cells

Abstract

The invention discloses full-automatic low-temperature storage equipment for stem cells, and relates to the technical field of low-temperature storage. The full-automatic low-temperature stem cell storage equipment comprises a cooling device, the cooling device comprises a cooling shell, a placement device is arranged at the center of the interior of the cooling shell and comprises a placement shell, an upper end opening of the placement shell is flush with an upper end opening of the cooling shell, and the lower end of the placement shell is located above the lower end of the cooling shell; a bottom hole is formed in the middle of the lower end of the containing shell in a penetrating mode, side holes are formed in the left side wall and the right side wall of the middle of the containing shell in a penetrating mode, and a communicating device is arranged at the lower end of the interior of the cooling shell and comprises a bottom column. According to the full-automatic low-temperature storage equipment for the stem cells, a worker cannot be in contact with the temperature of nitrogen, so that test tubes filled with the stem cells can be safely taken out.

Description

technical field [0001] The invention relates to the technical field of low-temperature storage, in particular to a fully automatic low-temperature storage device for stem cells. Background technique [0002] In general, between stem cells and their terminally differentiated progeny cells there exists an intermediate population of progenitors known as "committed progenitors", which have limited expansion capacity and restricted differentiation potential. The function of these cell populations is to increase the number of differentiated cells that stem cells produce after each division. Stem cells have the ability to self-renew, but the division of stem cells is actually relatively asymmetric. From a functional point of view, stem cells are cells with multi-directional differentiation potential and self-renewal ability. They are the most primitive cells at the top of the origin of cell lines, and can differentiate into cells of a specific tissue type in vivo. Once stem cells...

Problems solved by technology

At present, most of the stem cells on the market need to be stored at low temperature. Generally, the test tubes containing the stem cells are put into a box filled with nitrogen for uniform storage, and every time the test tube is taken out of the box, the nitrogen will overflow from the box mouth, making the Other test tubes containing stem cells in the box are affected, and the nitrogen gas overflowing from the box mouth will frostbite the staff, which is very unsafe. Therefore, there is an urgent need for a fully automatic low-temperature storage device for stem cells to solve the above problems
