A storage rack for umbilical cord mesenchymal stem cells

Abstract

The present invention relates to the field of stem cell storage, in particular to a storage shelf for umbilical cord mesenchymal stem cells, including a liquid nitrogen tank and an air storage tank. The storage shelf includes a cylindrical carrier with a hollow structure, a guide assembly installed in the carrier, and The stepper motor used to drive the guide assembly to rotate around the axis of the carrier; the liquid nitrogen tank communicates with the carrier body through the first air pipe; the gas storage tank communicates with the carrier body through the second air pipe; at least six The storage plate frame for storing stem cells; when the stepping motor drives the guide assembly to rotate, each storage plate frame is always in a horizontal posture; a pressure detector and a temperature sensor are installed in the carrier body, and the present invention can store a large number of stem cells. It does not affect the taking of the staff, and the stem cells can be easily isolated during the taking, so that it is not affected by the external temperature, which greatly facilitates the operation of the staff.

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
