Stem cell storage protection extractor

Abstract

The invention discloses a stem cell storage protection extractor, and belongs to the technical field of stem cell storage. The stem cell storage protection extractor comprises a base plate, a top cover, five test tube boxes and a rotating column, the top cover is arranged on the upper side of the base plate, the top cover and the base plate are coaxially arranged, and the rotating column is concentrically arranged between the top cover and the base plate; the five test tube boxes are arranged between the top cover and the base plate according to a certain distance, each test tube box is internally provided with a connecting piece and a test tube placing plate, each test tube placing plate is internally provided with a plurality of placing grooves, the top cover is further provided with five clamping blocks, each clamping block is provided with a nitrogen pipe, and the nitrogen pipe is internally provided with a containing cavity with an upward opening; and each nitrogen pipe is provided with a deflation groove, when the nitrogen pipes move upwards along with the clamping blocks, the bottoms of the nitrogen pipes are attached to the top cover, nitrogen cannot flow into the test tube boxes, and the situation that when stem cell test tubes are taken out, a large amount of liquid nitrogen in a container is lost, the temperature in the container rises, and storage of stem cells is affected is prevented.

Description

technical field [0001] The invention relates to the technical field of stem cell storage, in particular to a stem cell storage protection extractor. Background technique [0002] Stem cells are a type of pluripotent cells with self-renewal ability. Under certain conditions, they can differentiate into a variety of APSC pluripotent cells. They are a type of primitive cells with self-replication and multi-directional differentiation potential, that is, stem cells remain undifferentiated state and has the ability to proliferate, under suitable conditions or given suitable signals, it can differentiate into a variety of functional cells or tissues and organs. "Cells that can do anything", stem cells come from embryos, fetal tissues and adult tissues. Embryonic stem cells from embryos and fetal tissues have multipotential differentiation characteristics, and can differentiate into almost all more than 200 mature cell types in mature individuals, but now The protective performanc...

Problems solved by technology

[0003] The invention provides a stem cell storage and protection extractor to solve the technical problem in the prior art that when the stem cell test tube is taken, a large amount of liquid nitrogen in the container will be lost, which will cause the temperature in the container to rise and affect the storage of stem cells
