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.
