Pharmaceutical cold chain logistics is a branch of the logistics industry, specifically refers to a system project between the producer and the user of refrigerated pharmaceutical entities for the purpose of disease prevention, diagnosis and treatment of people. At this stage, my country's pharmaceutical cold chain logistics is still in the initial stage of development. In comparison, the US pharmaceutical cold chain logistics system is relatively sound.

   The market concentration of pharmaceutical companies in the United States is high, and the relevant management system is more complete. In the medical cold chain logistics in the United States, large-scale pharmaceutical wholesale companies and pharmaceutical companies are usually the linking hub, and pharmaceutical products need to be concentrated in the cold-chain logistics center of large-scale pharmaceuticals, and then the final cold chain distribution is carried out. This highly concentrated cold chain logistics model makes full use of the scale effect, avoids many and complex small orders in the market, and has a high market concentration. At the same time, the United States usually supervises and reversely traces the entire process of medical cold chain logistics through a wireless cold chain monitoring platform.

   In terms of medical cold chain logistics and transportation, the application rate of the Internet of Things technology in the United States is also very high. The United States applies RFID and GPS equipped with temperature control systems to monitor the temperature of medicines in real time through automatic temperature control and temperature monitoring, and keep the medicines refrigerated transportation temperature within the range of 2-8℃ to ensure the temperature of vaccines, biological preparations and other medicines during the cold chain transportation. monitor.

  At present, international organizations and some developed countries have issued relatively mature medical cold chain logistics standard guidelines. The United Blood Center of the United States has strict regulations on the temperature control, refrigerant varieties, and blood container specifications for the cold chain transportation of blood component products. It is clearly ordered that all links of the cold chain logistics must be equipped with detailed tracking forms. The American Cold Chain Association has also issued the "Cold Chain Quality Standards", which covers refrigerated pharmaceutical packaging, temperature control, and cold chain facility equipment standards to accurately test the standardization of pharmaceutical refrigeration, cold chain packaging, and pharmaceutical cold chain transportation. It provides a basis for the standard certification of American pharmaceutical cold chain transportation.
