Stem Cell Cryopreservation Box

Abstract

The invention relates to a low-temperature storage box for stem cells, and relates to the field of medical appliances. The main purpose of the invention is to solve the technical problem that the lower collection bag inside the existing cryopreservation box takes a long time to take out and affects the freezing effect of stem cells. The technical scheme mainly adopted is: a stem cell cryogenic preservation box, including a box body, a collection bag accommodation mechanism and a position adjustment mechanism. The box body has a box cover and a pick-and-place opening on the side, and the box cover can be opened and closed relative to the pick-and-release opening; the collection bag accommodation mechanism includes a support plate and a pressure plate arranged in parallel, and the pressure plate is located above the support plate; the pressure plate can move relative to the support plate, When moving to the first position, an accommodation gap for placing the collection bag is formed between the two, and the gap opening of the accommodation gap is opposite to the pick-and-place opening; and when moving to the second position, pressure is applied to the collection bag; the position adjustment mechanism is used Cooperating with the case cover, the pressure plate is located at the first position when the case cover is opened; and the press plate is located at the second position when the case cover is closed.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to a low-temperature storage box for stem cells. Background technique [0002] Human umbilical cord blood stem cells are usually stored in a low-temperature refrigerator / liquid nitrogen tank at -85°C or -196°C according to the required storage period. For umbilical cord blood stem cells that have a short period of time from collection to use (<6 months), cryopreservation at -85°C is usually used in a deep cryogenic refrigerator. During the specific operation, the umbilical cord blood stem cells are usually collected in a plastic collection bag, and then stored in a container with a specific structure such as a cryopreservation box, and the cryopreservation box is placed in a low-temperature refrigerator, and the human umbilical cord blood stem cells are collected. Cool down. [0003] At present, cryopreservation boxes are generally opened at the top, and the collecti...
