摘要:A cold box capable of maintaining a temperature below +4°C for 1 week was constructed and tested in the laboratory and under field conditions. Cooling is produced by commercial cold packs precooled in a deep-freeze or the freezing compartment of a refrigerator. The box can take approximately 3000 doses of vaccine and is simple, cheap and strong. It is primarily intended for storage of vaccines during field trips by vaccination teams, as an alternative to the refrigerator in regional and peripheral stores in the case of an electrical power failure, and for the delivery of vaccines from regional store to the district.
