Convenient medical stem cell preservation device

Abstract

The invention relates to the technical field of medical equipment, and relates to a convenient medical stem cell preservation device. The medical stem cell preservation device comprises a tank, spacing and pressing plates, a lifting drive mechanism and a fixing mechanism, wherein the more than two spacing and pressing plates are arranged sequentially in the tank along the height direction, and canlift up and lower down in the tank; a connecting mechanism is arranged between each two adjacent spacing and pressing plates; in the height direction, one spacing and pressing plate located above canget close or be far away relative to the adjacent spacing and pressing plate located below; an opening for picking and placing a stem cell collection bag is formed between one spacing and pressing plate located above and the adjacent spacing and pressing plate located below when the spacing and pressing plate located above lifts up and is far away to arrive at the extreme position; the spacing and pressing plate located above is linked with the adjacent spacing and pressing plate located below through the corresponding connecting mechanism; the lifting drive mechanism is used for being optionally connected with any one spacing and pressing plate; and the fixing mechanism is used for fixedly connecting any different spacing and pressing plates. A medical worker can only loosen a corresponding stem cell collecting bag according to the needs, and collecting bags which do not need to be taken out keep at pressing states so as to be prevented from being damaged.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a portable medical stem cell storage 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. In specific operations, umbilical cord blood stem cells are usually collected in plastic collection bags, and then packed in a container with a specific structure such as a medical stem cell storage device, and the medical stem cell storage device is placed in a low-temperature refrigerator to cool down the human umbilical cord blood stem cells. [0003] Currently, if figure 1 As shown, a medical stem cell preservation device is disclosed in the patent No. CN108207933...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned medical stem cell storage device 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 medical stem cell storage device, and in order to prevent adhesion, only one stem cell collection bag 10 is placed in each collection bag accommodation mechanism. bag of 10

When the medical staff opened the medical stem cell preservation device, the pressure plates 4 on the stem cell collection bags 10 of all patients rebounded and opened, and after the medical staff took out the stem cell collection bags 10 corresponding to the patients, they closed the case lid, and the stem cell collection bags 10 of other patients were opened again. It is pressed and fixed again by the corresponding pressing plate 4, 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
