A specimen transfer box

Abstract

The invention relates to the technical field of medical devices, in particular to a specimen transfer box, comprising a refrigerating box body with low-temperature water built in, a refrigerating box cover that is snap-connected to the top of the refrigerating box body, is arranged in the refrigerating box body and is used for placing ice cubes Or the mesh cylinder of the ice bag, a plurality of transfer cylinders located in the refrigerating box and located on the outer circumference of the mesh cylinder, and a planetary rotating mechanism that drives the mesh cylinder and the transfer cylinder to rotate in opposite directions; A polished rod penetrating through the net cylinder is fixed, a screw rod fixed on the top of the polished rod is fixed, and a pulling rod is movable through the refrigerator cover and is rotatably connected with the screw rod. The invention provides a refrigeration source through ice cubes or ice packs, and uses low-temperature water as a heat exchange medium to achieve rapid cooling and refrigeration of the specimen, and drives the mesh cylinder and the transfer cylinder to rotate in opposite directions through a planetary rotating mechanism, so as to improve the heat exchange efficiency of the low-temperature water. Avoid heat exchange dead zones.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a specimen transfer box. Background technique [0002] Clinically, the correct collection, transportation, preservation and processing of specimens are essential to ensure the quality of clinical laboratory work. Generally, after the medical staff collects the specimens according to the characteristics of the collected specimens, they need to transport the specimens to the laboratory for inspection through a transfer box. The transfer box generally needs to carry out the whole process of cold chain transportation of the samples during the transfer process to ensure the quality of the test results of the samples. [0003] The utility model patent publication number CN208326200U discloses a medical test specimen transfer box, the transfer box includes a heat preservation box body, and the heat preservation box body adopts a semiconductor refrigeration device to realize ref...

Problems solved by technology

However, when the cold end of the semiconductor refrigeration device is used for cooling, it is necessary to effectively dissipate heat at the hot end. The heat to be dissipated includes the heat released by the Parnell effect and the Joule heat of the cooling sheet itself. This heat is far greater than the heat absorbed by the cold end. Large, so semiconductor cooling efficiency is low and energy consumption is high
