Specimen transfer box

Abstract

The invention relates to the technical field of medical instruments, in particular to a specimen transfer box which comprises a refrigeration box body containing low-temperature water, a refrigeration box cover connected with the top of the refrigeration box body in a buckled mode, a net cylinder arranged in the refrigeration box body and used for containing ice blocks or ice bags, and a plurality of transfer cylinders arranged in the refrigeration box body and located on the periphery of the net cylinder. The planetary rotating mechanism is used for driving the net cylinder and the transfer cylinder to rotate in different directions; the planetary rotating mechanism comprises a polished rod located at the axis of the net barrel and fixedly penetrating through the net barrel, a screw rod fixedly arranged at the top end of the polished rod, and a drawing rod movably penetrating through the refrigerating box cover and rotationally connected with the screw rod. A refrigeration source is provided through ice cubes or ice bags, low-temperature water serves as a heat exchange medium, the specimens are rapidly cooled and refrigerated, the planetary rotating mechanism drives the net barrel and the transfer barrel to rotate in different directions, the heat exchange efficiency of the low-temperature water is improved, and a heat exchange dead zone is avoided.

Description

Technical field [0001] The present invention relates to the technical field of medical devices, specifically a specimen transfer box. Background [0002] Clinically, the correct collection, transportation, preservation and handling of specimens is essential to ensure the quality of clinical testing work. In general, after the medical staff collects the specimens according to the characteristics of the specimens collected, the specimens need to be transported to the inspection department through the transfer box for inspection. The transfer box generally needs to carry out the whole process of cold chain transportation of the specimen during the transfer to ensure the quality of the specimen test results. [0003] The utility model patent with the publication number CN208326200U discloses a medical examination specimen transfer box, which includes an incubator, and the incubator is cooled by a semiconductor cooling device. However, the use of semiconductor refrigeration device col...

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
