Abstract

The invention discloses a self-tissue stem cell isolated application constant-temperature preservation device. The self-tissue stem cell isolated application constant-temperature preservation device comprises a box body, wherein the rear side of the upper end of the box body and the lower end of a cover plate are connected through a hinge in a rotating mode, the bottom surface inside the box bodyis fixedly connected with the lower surface of an air-permeable net through an elastic device, the side face of the air-permeable net is connected with the inner wall of the box body in a sliding mode, two containing boxes are fixed on the upper surface of the air-permeable net, buckling devices are installed on the upper surfaces of the two containing boxes, the damping performance of the containing boxes is improved through the elastic device, a collecting bag filled with mesenchymal stem cells is prevented from shaking by a rubber air bag, and the activity of the mesenchymal stem cells is guaranteed; when the temperature in the box body is lower than the set temperature, a PLC controls a draught fan and a semiconductor refrigerating piece to work, the draught fan enables cold air generated by the semiconductor refrigerating piece to be evenly distributed in the box body, the temperature of the box body is maintained within a set range, and the reliability of the self-tissue stem cell isolated application constant-temperature storage device is improved.

Description

technical field [0001] The invention relates to the technical field of stem cell preservation, in particular to a constant temperature preservation device for autologous tissue stem cells in vitro. Background technique [0002] The placenta contains a large number of mesenchymal stem cells. Mesenchymal stem cells have the characteristics of multi-lineage differentiation potential, hematopoietic support and promotion of stem cell implantation, immune regulation and self-replication, and have attracted people's attention. Therefore, the placenta is often processed to extract mesenchymal stem cells, and doctors store the mesenchymal stem cells at a constant temperature. At present, mesenchymal stem cells are mainly stored in collection bags, preserved with a protective solution, placed in a thermal insulation device, and a biological ice pack is used to maintain a low temperature environment. The structure of the existing equipment is complicated, and the collection bag will c...
