Abstract
A heating cabinet for IV bags provides a uniform thermal field promoted by circulated heated air passing through air permeable shelves. Temperatures of the IV bags are modeled through a knowledge of a temperature of the uniform thermal field and arrival time of the IV bags eliminating a need for separate temperature sensors and control loops. Bag status may be signaled through modulated light distinguishable by individuals with limited color sensitivity. Signals are associated with particular IV bags by projecting the light of the signals into the IV bags themselves.
