Abstract
An inflation indicator for a cuffed tracheal tube has a plastics envelope with two walls sealed around their edges. An elongate indentation is formed along the inner surface of each wall along the length of the envelope to provide a continuous fluid passage between the walls, between a valved coupling and an inflation lumen, when the walls contact one another on collapse of the envelope.
