An improved blood shipping container, providing safer storage of blood in transit over longer periods of time, has been developed. This plastic foam “blood shipper” incorporates an insulated refrigerant system of wet ice. Icing and storage data have been collected for two ambient conditions, a “normal day” (up to 23 C) and a “hot day” (up to 36 C). The storage requirements for blood in transit are based upon the criteria of the standard 1 to 10C and the preferred 1 to 6C range. When the blood was precooled to 1 to 6 C and iced as directed with 1,800 Gm of wet ice, the shipper was found to maintain eight units within 1 to 10 C for 40 hours at normal temperatures and for 30 hours at elevated temperatures. The eight units were maintained within 1 to 6 C for 30 hours at normal temperatures and for 18 hours at elevated temperatures. Without ice, the units were maintained at 1 to 10C for only 6 hours at normal temperatures and for only 2.5 hours at elevated temperatures. Recommendations are made concerning methods of temperature measurement.
