Cord blood stem cell freezing preserving device

Abstract

The invention relates to a cord blood stem cell freezing preserving device and relates to the field of medical appliances. The cord blood stem cell freezing preserving device mainly aims to solve thetechnical problem that the taking-out time of a collecting bag of the lower layer of the interior of an existing freezing preserving box is long and thus the stem cell freezing effect is affected. According to the mainly-adopted technical scheme, the cord blood stem cell freezing preserving device comprises a box body, a collecting bag containing mechanism and a position adjusting mechanism; the box body is provided with a box cover and a taking and placing opening located in the side face, and the box cover can be opened and closed relative to the taking and placing opening; the collecting bag containing mechanism comprises a supporting plate and a pressing plate which are parallelly arranged, and the pressing plate is located above the supporting plate; the pressing plate can movable relative to the supporting plate, so that when the pressing plate moves to the first position, a containing gap for preserving collecting bags is formed between the pressing plate and the supporting plate, and a gap opening of the containing gap is opposite to the taking and placing opening; when the pressing plate moves to the second position, the pressure is applied to the collecting bags; and theposition adjusting mechanism is used for being matched with the box cover, so that when the box cover is opened, the pressing plate is located on the first position, and when the box body is closed, the pressing plate is located on the second position.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to a cryopreservation device 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 umbili...
