Biological sample transferring box and method

Abstract

The invention provides a biological sample transferring box and method. The transferring box is provided with a multilayer protection structure and comprises a sample protection box, an inner heat preservation box and an outer heat preservation box. The sample protection box is used for containing a sample container containing a biological sample. The sample protection box is arranged in the low-temperature negative-pressure inner heat preservation box. The inner heat preservation box is arranged in the heat preservation box with a heat preservation function. The inner heat preservation box comprises an inner box with an inner heat preservation layer and an inner box cover matched with an opening in the upper end of the inner box. A gas channel assembly communicating with the interior of the inner box is arranged on the inner box cover. The biological sample transferring box is convenient to use, safe and reliable; by arranging two heat preservation layers, heat exchange between the outside and the interior of the box is reduced; and by placing an ice box in the inner heat preservation box, the interior of the inner box is vacuumized through the gas channel assembly arranged on theinner box cover, the biological sample is in a low-temperature negative-pressure condition, and it is avoided that biological factors possibly with biological safety risks are diffused to the outsideto pollute the environment.

Description

technical field [0001] The invention belongs to the technical field of biological sample detection auxiliary devices, and in particular relates to a biological sample transfer box and a biological sample transfer method. Background technique [0002] The detection of biological samples usually needs to be carried out in laboratories with corresponding biosafety protection levels according to the relevant regulations according to the biosafety level, and it is inevitable to store and transport the prepared biological samples. In order to ensure biological safety, prevent the spread of biological factors, and aerosols to cause harm to the surrounding biological environment, biosafety laboratories usually use negative pressure protection to make the laboratory relatively negative pressure to the outside atmosphere and limit harmful aerosols to the experimental environment. Indoor, and then through the gas high-efficiency filter to filter out biological factors and then discharg...

Problems solved by technology

There are some disadvantages in these methods, for example, it is difficult for ice packs to keep low temperature for a long time, and the transfer samples in the transfer box are in direct contact with the ice packs, causing rapid freezing, etc.
