Figure 2.

A . The SS-BOX-110, equipped with an internal thermocouple probe to record the internal temperature and an outer probe to measure the ambient temperature during transport. The five units of red blood cell components and a dummy blood bag for recording the liquid temperature are also displayed.

B. Five aliquots of red blood cells were put one by one in opposite directions after a bubble-sheet-wrapped frozen coolant had been placed on the bottom. Finally, the other wrapped frozen coolant was put on the top of the red blood cell bags, and a foam plug was used as the ceiling to ensure a tight fit.

C. The container containing five bags of red blood cells, a dummy blood bag and two frozen coolants is shown. The outer thermocouple probe for measuring the ambient temperature and the data logger can be seen.
