Cord Blood Stem Cell Cryopreservation Box

Abstract

The invention relates to an umbilical cord blood stem cell cryopreservation box, relates to the field of medical instruments and mainly solves the technical problem that the stem cell freezing effectis affected due to the fact that longer time is consumed when a collection bag on a lower layer in an existing cryopreservation box is taken out. According to the technical scheme, the umbilical cordblood stem cell cryopreservation box comprises a box body, collection bag accommodating mechanisms and position adjusting mechanisms; the box body comprises a box cover and an access port located on one side surface, and the box cover can be opened and closed relative to the access port; each collection bag accommodating mechanism comprises a support plate and a press plate which are arranged in parallel, and the press plate is located above the support plate; each press plate can move relative to the corresponding support plate, an accommodating gap used for accommodating a collection bag isformed between each support plate and the corresponding press plate when the press plate moves to the first position, and a gap port of the accommodating gap is opposite to the access port; each pressplate applies pressure to each collection bag when moving to the second position; the position adjusting mechanisms are matched with the box cover, so that the press plates are located in the first position when the box cover is opened and located 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 cryopreservation box for umbilical cord blood 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...

Problems solved by technology

[0004] In view of this, the present invention provides a cryopreservation box for umbilical cord blood 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 box and affects the freezing effect of stem cells
