The invention relates to a stem cell freezing and storing device, relates to the field of medical instruments, and mainly aims at solving the technical problems that the time for taking-out of a collection bag on the lower layer in an existing freezing and storing box is long, and the stem cell freezing effect is influenced. According to the technical scheme mainly adopted, the stem cell freezingand storing device comprises a box, a collection bag containing mechanism and a position adjusting mechanism. The box is provided with a box cover and a taking-placing port located in the side face, and the box cover can be opened and closed relative to the taking-placing port. The collection bag containing mechanism comprises a supporting plate and a pressing plate which are arranged in parallel,and the pressing plate is located above the supporting plate. The pressing plate can move relative to the supporting plate so that a containing gap for containing a collection bag can be formed between the pressing plate and the supporting plate when the pressing plate moves to the first position, and a gap port of the containing gap is opposite to the taking-placing port; pressure is applied tothe collection bag when the pressing plate moves to the second position; the position adjusting mechanism is used for being matched with the box cover so that the pressing plate can be located at thefirst position when the box cover is opened; and when the box cover is closed, the pressing plate is located at the second position.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to a stem cell cryopreservation device. 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 stem cells are...
