Background
The medical cold chain transportation needs to be carried by a refrigerator car, and the temperature is controlled to be 2-At the temperature of 8 ℃, and can not be transported together with fruits and seafood. The company like the Shufeng cold chain charges 250 Yuan for short-distance transportation within 100 kilometers, and the transportation cost is high.
Some companies with strong strength and large sales quantity configure refrigerated vehicles by themselves and transport medical cold chain goods by themselves. The companies with weak strength and low sales volume cannot arrange the refrigerator cars by themselves or carry the goods such as the smooth and rich cold chain.
The short-distance transportation can adopt foamThe heat preservation box is matched with a proper amount of ice bags, so that the temperature can be kept at 2 DEG-Transporting the medical biological product at 8 ℃. The traditional ice bag needs to be frozen in a refrigerator for 24 hours and can be used after cold accumulation. The refrigerator is depended on, the power supply is depended on, the time is limited, and the refrigerator cannot be taken and used at any time. For some outdoor and special cases, the refrigerator is not available, the power supply is not available, and the refrigerator is required to be used immediately, which is very inconvenient.
Some companies adopt a normal-temperature transportation mode for vaccines due to various condition limitations of medical cold-chain long-distance transportation and short-distance transportation, so that a toxic vaccine event with great social harm is caused. The vaccine stimulates the human immune system through the antigen part, thereby protecting the human health. The core of the vaccine is antigen, the biological activity of the antigen is not ensured, and most of the vaccines are 2-Storing and transporting at 8 deg.C. The problems caused by vaccine inactivation are two kinds: 1. vaccine inactivation is not perceived and can have serious consequences for vaccines such as rabies, tetanus and the like, by exposing the vaccinee unconsciously to the corresponding disease. 2. Inactivation of the vaccine, which corresponds to injection of the corresponding pathogen into the vaccinee, leads to the development of new diseases.
