At present, for cold-chain transportation of many medicines, biological products and the like (such as vaccines, antibody medicines, biological products such as serum and the like), special cold-chain transportation vehicles are required, and the special cold-chain transportation vehicles comprise a refrigerator car, a refrigerator ship, a refrigerated container and the like. However, these vehicles are complex and extremely costly and are only suitable for mass transport. Such conventional transportation devices are more costly when small batches of multiple transports are required for emergency rescue or other situations.
When biological products are transported in small batches, a portable insulation box is usually adopted, and the portable insulation box is small and exquisite in structure and convenient to transport. However, for vaccine transportation, the GSP and the regulations on vaccine circulation and vaccination management stipulate that the vaccine needs to be stored and transported under a cold chain at 2-8 ℃, and freezing is strictly prohibited; in the independent vaccine refrigerating boxes/bags adopted in the market at present, heat insulation materials are adopted as vaccine outer boxes, a plurality of blocks of the vaccine outer boxes (freezing agents and ice rows) which are precooled at the temperature of between 20 ℃ below zero and 30 ℃ below zero are added, and then target medicines are placed in a cold chain transport box for storage and transportation.
The conventional refrigerated container/bag that can be used for independent vaccine transportation in the medical field has the following disadvantages:
when the vaccine is in direct contact with the refrigerant, because the refrigerant (refrigerant and ice rows) is pre-cooled at the temperature of minus 20 ℃ to minus 30 ℃, when the refrigerant is put into the vaccine box, the instantaneous temperature of the outer wall of the vaccine box is lower than 0 ℃ due to the direct conduction effect of the temperature, the vaccine in the inner layer and the outer layer of the vaccine box is possibly frozen, and the bioactivity of the vaccine is seriously influenced and cannot reach the relevant regulation; the cold chain transport case is easy to damage when sending collision impact in the transportation process, and does not have impact resistance.
The CN201320624291.2 patent discloses a biological medicine cold chain transportation device, which comprises an insulation box, a cold accumulation plate arranged in the insulation box, an evaporator arranged in the cold accumulation plate, a temperature sensor arranged in the insulation box, a condenser arranged outside the insulation box, a refrigeration compressor, a temperature controller and a direct current battery; the input port of the evaporator is connected with the output port of the condenser, the input port of the condenser is connected with the output port of the refrigeration compressor, and the input port of the refrigeration compressor is connected with the output port of the evaporator; the signal input end of the temperature controller is connected with the signal output end of the temperature sensor, the signal output end of the temperature controller is connected with the signal input end of the refrigeration compressor, and the refrigeration compressor is controlled to start or stop by the temperature controller according to the temperature value detected by the temperature sensor. According to the technical scheme, the cold storage agent is subjected to phase change crystallization through the condenser, so that the cold storage agent does not have impact resistance and the temperature in the box body is unstable.
