A portable low temperature refrigerator

Abstract

The invention discloses a portable low-temperature refrigerated container. A container body is divided into a cold accumulation storage layer on the upper portion and a refrigeration device layer on the lower portion through a heat preservation partition plate. Heat preservation and thermal insulation materials are arranged on the four inner side walls and the top of the cold accumulation storage layer. Refrigeration drawers used for storing medicines are arranged on the left side and the right side of the cold accumulation storage layer respectively. A plurality of circular holes with covers are formed in the top of the cold accumulation storage layer. Cold accumulation hollow columns used for storing the medicines are placed in the circular holes, wherein the inner walls and the outer walls of the cold accumulation hollow columns are filled with cold accumulation agents. A compressor, a condenser, capillary tubes and the like are arranged on the refrigeration device layer. Vent holes are formed in a front panel and a rear panel. The refrigeration mode is a directly cooling type or an indirectly cooling type. Evaporators are arranged on the cold accumulation storage layer or the refrigeration device layer. The portable low-temperature refrigerated container comprises a plurality of storage spaces. The medicines are stored in a classified manner. The cold loss caused when the medicines are taken multiple times is reduced. Meanwhile, the long refrigeration time and the accurate temperature control function are achieved. The heat exchange efficiency of the indirect cooling type is higher than that of the direct cooling mode, and frost can be restrained. The portable low-temperature refrigerated container has the beneficial effect of being light and can be moved as a whole, the cold storage hollow columns can be independently carried, and the application range is wide.

Description

technical field [0001] The invention relates to a medicine low-temperature preservation device, in particular to a portable low-temperature refrigerator. Background technique [0002] Refrigerated medicines refer to medicines that have temperature requirements such as cold places and freezing for medicine storage and transportation. Most of these medicines are sensitive to drastic changes in ambient temperature, and changes in temperature are likely to reduce or even lose the efficacy of medicines. In the cold chain logistics process of these drugs, there are extremely strict requirements in terms of drug production, logistics transportation and storage. Among them, there are many problems in the use of refrigerated medicines. Most medical institutions use simple refrigerators for the transfer of refrigerated medicines from pharmacies to wards. Hospitals with poor conditions do not use any cold storage measures and directly transfer them. After the refrigerated medicines ar...

Problems solved by technology

Among them, there are many problems in the use of refrigerated medicines. Most medical institutions use simple refrigerators for the transfer of refrigerated medicines from pharmacies to wards. Hospitals with poor conditions do not use any cold storage measures and directly transfer them. After the refrigerated medicines are taken out of the pharmacy cold storage, the ambient temperature of the medicines rises sharply, especially in the hot summer, where the temperature difference is even greater. During the transfer process, it will affect the efficacy of the drug

There are also some problems in the simple refrigerators used by some medical institutions: 1. Since most of them use ice packs to keep cold, the refrigeration time is short and the temperature control is not accurate

2. Most of these refrigerated boxes use a flip-type top cover. When opening the top to take medicine, it will cause the loss of cold air in the box and increase the temperature inside the box.

Moreover, different medicines or medicines of different patients are mixed in the same space, and the upper cover is opened many times, which will intensify the loss of cold air.
