ABSTRACT:
An apparatus for equalizing pressure in a middle ear including a compressor, activating means coupled to the compressor, the activating means having a closed state and an open state, the open state providing a continuous flow of air from the compressor at a predetermined pressure, and a tapered nostril plug in communication with the compressor, the nostril plug having a distal opening for delivering the continuous flow of air, the predetermined pressure being in the range of approximately 0.5 p.s.i. to approximately 3.0 p.s.i. In addition, an apparatus for equalizing pressure in a middle ear including a compressor, activating means coupled to the compressor, the activating means having a closed state and an open state, the open state providing a continuous flow of air from the compressor at a predetermined rate; and a tapered nostril plug in communication with the compressor, the nostril plug having a distal opening for delivering the continuous flow of air, the predetermined rate being in the range from approximately 1.0 liter/minute to approximately 4.0 liters/minute.
