ABSTRACT:
An apparatus for equalizing pressure in a middle ear includes a hand-held air source for providing a continuous flow of air at a predetermined rate and a tapered sealing nostril plug adapted to be sealed against a nostril. The tapered nostril plug has a channel there through for delivering the continuous flow of air. The channel of the tapered plug is adapted to be placed in communication with the air source through an adjustable valve assembly for selecting a pressure limit for the air in the channel of the nostril plug.
