Portable blood cold insulation box

Abstract

The invention provides a portable blood cold insulation box comprising a box body made of a heat insulation material. A containing cavity is formed in the box body. A plurality of independent cold insulation subareas are formed in the containing cavity. The subareas are mutually separated through blocking structures. Each cold insulation subarea is provided with a containing drawer used for storing blood. The box body is provided with a cold insulation device comprising a Stirling motor. The cold end of the Stirling motor directly or indirectly makes contact with the interiors of the cold insulation subareas so as to lead cold energy into the cold insulation subareas. The portable blood cold insulation box plays a good role in protection while being convenient to carry, and the cold insulation effect is guaranteed; meanwhile, cold is supplied to the Stirling motor through a power source, so that the cold supply efficiency is guaranteed; and the blood cold insulation box is convenient to carry, suitable for narrow places and suitable for storage of the medial blood.

Description

Technical field [0001] The invention relates to the technical field of cold preservation, in particular to a portable blood cold preservation box. Background technique [0002] At present, with the development of the food logistics industry, more and more frozen products have created new demand for transportation. For example, buying frozen food from supermarkets and other places. If it takes time or a long distance, the frozen food will melt, which will easily affect the food. Quality, it is difficult to play a role in keeping fresh, and in the medical supplies market, some blood and other substances need to be kept cold for a long time. However, the existing cold preservation tools are generally refrigerated cars, which are too large for personal use. Or other places where the space is relatively narrow, the restrictions are greater, and especially for the transportation of blood, blood of different blood types needs to be stored separately to improve the efficiency of blood pr...

[0002] At present, with the development of the food logistics industry, more and more frozen products have created new demands for transportation, such as purchasing frozen food to and from supermarkets and other places. If it takes time or the distance is long and the frozen food melts, it will easily affect the food. quality, it is difficult to keep fresh, and in the medical supplies market, the refrigeration of some blood and other substances also needs to be kept cold for a long time, but generally the existing cold storage tools are refrigerated cars, which are not suitable for personal use due to their large size. Or other places where the space is relatively narrow, the transportation is relatively limited, and especially the transportation of blood, the blood of different blood types needs to be stored separately to improve the efficiency of blood storage, and correspondingly, it is necessary to control the temperature of each type of blood separately. In this way, the demand for cold storage devices is increased, so a cold storage box that is small in size and can transport various types of blood is needed
