Device for preserving umbilical cord blood stem cells

Abstract

The invention relates to the technical field of medical equipment, and relates to a device for preserving umbilical cord blood stem cells. The device comprises a box body, pressure separating plates,a lifting driving mechanism and a fixing mechanism. The two or more pressure separating plates are arranged, and all the pressure separating plates are arranged in the box body in sequence in the height direction and can ascend and descend in the box body. A connecting mechanism is arranged between every two adjacent pressure separating plates. In the height direction, each pressure separating plate located on the upper portion can relatively get close to or keep away from the corresponding adjacent pressure separating plate on the lower portion, an opening which allows a corresponding stem cell collection bag to be taken and placed is formed between every two adjacent pressure separating plates when the corresponding pressure separating plate located on the upper portion ascends and keepsaway to arrive at the extreme position, and each pressure separating plate located on the upper portion is linked with the corresponding adjacent pressure separating plate located on the lower portion through the corresponding connecting mechanism. The lifting driving mechanism is used for being optionally connected with any pressure separating plate. The fixing mechanism is used for enabling therandom different pressure separating plates to be fixed and connected. A medical worker can just loosen the corresponding stem cell collection bag as required, the collection bags which do not need to be taken out can be kept in a press-fit state, and the damage is avoided.

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
