ABSTRACT:
A device for regulating pressure which can be used to relieve discomfort caused by inner ear pressure. The device includes a hollow body having an open end, a movable member within the hollow body which defines a first chamber that extends between the movable member and the open end of the hollow body, and various alternative structural elements which regulate pressure in the first chamber. To relieve discomfort caused by inner ear pressure, the open end of the hollow body is provided with a mouthpiece. A person experiencing discomfort caused by inner ear pressure, blows through or sucks on the mouthpiece, causing a change in pressure in the first chamber. The device regulates pressure in the first chamber in such a way to help relieve the person's inner ear pressure.
