Storage rack for umbilical cord mesenchymal stem cells

Abstract

The invention relates to the field of stem cell storage and especially relates to a storage rack for umbilical cord mesenchymal stem cells. The storage rack comprises a liquid nitrogen container, a gas storage tank, a carrier, a guiding component and a stepping motor, wherein the carrier is of cylindrical shape and has a hollow structure; the guiding component is arranged in the carrier; the stepping motor is used for driving the guiding component to rotate around the axis of the carrier; the liquid nitrogen container is connected with the interior of the carrier through a first gas pipe; thegas storage tank is connected with the interior of the carrier through a second gas pipe; at least six storage plates for storing stem cells are arranged on the guiding component; when the guiding component is driven to rotate by the stepping motor, each storage plate is under a horizontal state all the time; a pressure detector and a temperature sensor are arranged in the carrier. According to the invention, the operation of operator for taking the stem cells is not influenced under the condition that a large quantity of stem cells are stored, and meanwhile, the stem cells can be convenientlyisolated when the operator takes the stem cells, the stem cells are not influenced by external temperature and a great convenience is brought to the operation of the operator.

Description

technical field [0001] The invention relates to the field of stem cell storage, in particular to an umbilical cord mesenchymal stem cell storage shelf. Background technique [0002] Mesenchymal stem cells are an important member of the stem cell family, derived from the mesoderm in the early development stage, and belong to pluripotent stem cells. Mesenchymal stem cells were originally found in the bone marrow because of their multidirectional differentiation potential, hematopoietic support and promotion of stem cell implantation, The characteristics of immune regulation and self-replication have attracted more and more attention. The clinical application of mesenchymal stem cells to solve a variety of blood system diseases, cardiovascular diseases, liver cirrhosis, nervous system diseases, partial knee meniscectomy injury repair, autoimmune diseases, etc. have made major breakthroughs and saved more patients. Suffering life. Additionally, mesenchymal stem cells hold grea...

Problems solved by technology

[0005] The disadvantage of the above solution is that: the use of drawer-type storage compartments for storage will lead to more troublesome operation during later use, which is not conducive to the work of the staff. If the specifications of the storage compartments are made relatively small, then storage The amount will be greatly reduced, because sometimes the stem cells are taken out or put in in batches, and most of the stem cells will be exposed outside when the drawer-type storage is pulled more often, which will be affected by external heat energy and increase the internal cooling equipment. work pressure
