A device for preserving umbilical cord blood stem cells

Abstract

The present invention relates to the technical field of medical equipment, and it relates to a device for preserving umbilical cord blood stem cells. The device includes a box body, a pressure partition, a lifting drive mechanism and a fixing mechanism; The cabinets are arranged in sequence along the height direction, and can be lifted and lowered in the cabinet; there is a connecting mechanism between each adjacent two pressure partitions; in the height direction, the upper pressure partition can be closer to the adjacent lower pressure partition or away from it, and when it rises away from the limit position, an opening for the stem cell collection bag to be taken and placed is formed between the two, and is linked with the adjacent lower pressure partition through the connection mechanism; the lifting drive mechanism is used to selectively connect with any Pressure partition connection; the fixing mechanism is used to securely connect any different pressure partitions. Among them, the medical staff can only loosen the corresponding stem cell collection bag as needed, so that the collection bag that does not need to be taken out remains in a pressed state to prevent damage.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a device for preserving 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. In specific operations, cord blood stem cells are usually collected in a plastic collection bag, and then packed in a container with a specific structure such as a device for preserving cord blood stem cells, and the device for preserving cord blood stem cells is placed in a low-temperature refrigerator for human cord blood Stem cells are cooled. [0003] Currently, if figure 1 As shown, the patent No. CN108207933B discloses a device for storing umbilical...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned device for storing umbilical cord blood stem cells has at least the following defects: in order to save resources, generally a plurality of stem cell collection bags 10 of different patients are stored in one device for storing umbilical cord blood stem cells, and in order to prevent adhesion, each collection Only place a stem cell collection bag 10 in the bag accommodation mechanism

When the medical staff opened the device for storing umbilical cord blood stem cells, the pressure plates 4 on the stem cell collection bags 10 of all patients would rebound and open. 10 is pressed and fixed by the corresponding pressing plate 4 again, so that the stem cell collection bag 10 that has not been taken out is prone to damage during the repeated loosening and pressing process, so it is urgent to solve this situation
