Automatic biological sample library capable of independently cooling

Abstract

The invention relates to an automatic biological sample library capable of independently cooling. The automatic biological sample library comprises a liquid nitrogen tank, a basket bin, a basket module, a pipe picking bin and a pipe picking module, wherein the liquid nitrogen tank comprises a heat preservation tank body and a basket contained in the heat preservation tank body, the basket bin is arranged on the upper part of the liquid nitrogen tank, the basket bin is provided with an openable box outlet; the basket module comprises a basket assembly, a basket cooling assembly and a shovel disc assembly, the basket assembly is used for lifting the basket in the liquid nitrogen tank into the basket bin, and the shovel disc assembly is used for moving a cryopreservation box in the basket tothe box outlet; the pipe picking bin is provided with an openable box inlet, and when the box outlet and the box inlet are both opened, the cryopreservation box can enter the pipe picking bin; and thepipe picking module comprises a pipe picking cooling assembly and a pipe picking assembly. The basket bin and the pipe picking bin are independently arranged and are respectively cooled, and comparedwith a scheme of cooling a bin body for communicating the basket bin with the pipe picking bin, the scheme of independently cooling reduces the total cooling area, the cooling efficiency is improved,the cooling cost is reduced, and the working efficiency of the automatic biological sample library is improved.

Description

technical field [0001] The invention relates to the technical field of biological sample storage, in particular to an automatic biological sample bank that can be cooled independently. Background technique [0002] Biobank is a device for standardized collection, processing, and storage of biological macromolecules, cells, tissues, and organs of healthy and diseased organisms. Most biological samples need to be stored in a deep low temperature environment, especially for some The biological sample bank of cells transfused into the human body needs to be stored at a temperature close to liquid nitrogen. Take the biological sample bank for storing human embryos as an example. The embryos need to go through a complicated cooling process, and then put them into liquid nitrogen for storage. In the traditional biological sample bank, biological samples are stored in the basket of the liquid nitrogen tank. During the storage and extraction process, the basket, shovel plate, and pi...
