Preservation device for reproductive embryonic stem cells

Abstract

The invention discloses a preservation device for reproductive embryonic stem cells, and relates to the technical field related to reproductive embryonic stem cells, and the preservation device is characterized by comprising a box body, a display operation screen, a fingerprint identifier, a password input device, a refrigeration box, a liquid nitrogen box, a guide pipe, an electromagnetic valve, a temperature sensor, a servo motor, a rotating shaft, a fixed part and a plurality of brackets, a U-shaped placing piece, a fixed inserting sleeve, a storage pipe, a sealing cover and a rolling piece are arranged at the end part of the bracket; connecting blocks are arranged at the bottoms of the two sides of the fixed inserting sleeve; a guide groove and a spring are arranged on the inner side wall of the U-shaped placing piece; an access hole is formed in the top end of the refrigeration box; a bolt is inserted into the access hole; an opening, a telescopic cylinder, an electronic locking piece, a sealing plate and a lock catch are arranged at the top end of the box body; and a PLC and a power supply device are arranged in the box body. According to the device, the refrigeration effect of other stored embryonic stem cells is not affected when the embryonic stem cells are stored and taken, storing and taking operation is easy and convenient, and meanwhile the device is high in safety and not prone to being stolen.

Description

technical field [0001] The present invention relates to the relevant technical field of reproductive embryonic stem cells, more specifically, it relates to a storage device for reproductive embryonic stem cells. Background technique [0002] Stem cells are a type of pluripotent cells with self-renewal ability. Under certain conditions, they can differentiate into a variety of APSC pluripotent cells. They are a type of primitive cells with self-replication and multi-directional differentiation potential, that is, stem cells remain undifferentiated state and has the ability to proliferate, under suitable conditions or given suitable signals, it can differentiate into a variety of functional cells or tissues and organs. Any cell." Stem cells are derived from embryonic, fetal and adult tissues. Embryonic stem cells derived from embryonic and fetal tissues have pluripotent differentiation properties and can differentiate into almost all of the more than 200 mature cell types in...

AI Technical Summary

Problems solved by technology

When the existing cryopreservation device takes out the cryopreservation tube, the storage box is completely opened, which easily affects the cryopreservation effect of stem cells in other cryopreservation tubes in the cryopreservation device, and it is inconvenient to take and place the cryopreservation tube from the cryopreservation device, and the existing The security of the cryopreservation device is very low, it is easy to cause the embryonic stem cells to be stolen, and the degree of intelligence is low
