Low-temperature stem cell preservation box

Abstract

The invention relates the field of medical instruments, particularly to a low-temperature stem cell preservation box. The low-temperature stem cell preservation box mainly aims at solving the technical problem that taking out a lower-layer collecting bag inside an existing freezing preservation box is long in time to result in influence on stem cell freezing effects. According to the technical scheme, the low-temperature stem cell preservation box comprises a box body, a collecting bag containing mechanism and a position adjusting mechanism, wherein the box body is composed of a box cover andan access port in the side surface, and the box cover can be opened and close relative to the access port; the collecting bag containing mechanism is composed of a support plate and a pressing plate which are arranged in parallel, and the pressing plate is arranged above the support plate and can move relative to the support plate; when the pressing plate moves to a first position, an accommodating gap for placing a collecting bag can be formed between the pressing plate and the support plate, and the opening of the accommodating gap is opposite to the access port; when moving to a second position, the pressing plate can press the collecting bag; the position adjusting mechanism is used for matching with the box cover so that the pressing plate can be in the first position when the box cover is opened and in the second position when the box 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), they are usually stored in a deep freezer at -85°C. 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 to cool down the human umbilical cord blood stem cells. [0003] At present, cryopreservation boxes are generally opened at the top, and the collection bags containing umbilical cord blood st...

AI Technical Summary

Problems solved by technology

[0004] In view of this, the present invention provides a low-temperature storage box for stem cells, the main purpose of which is to solve the technical problem that the extraction operation of the lower collection bag inside the existing cryopreservation box is cumbersome, which leads to too long opening time of the storage box and affects the freezing effect of stem cells
