Abstract
Various embodiments of devices to reduce or prevent nasal breathing and snoring are provided. In one embodiment, the devices have open tubular elements which are conic-frustum shaped along an axis, having a larger diameter first end and taper toward a second smaller diameter second end. The tubular elements may have passageways that extend transversely through the tubular elements. In another embodiment, the first ends of the tubular elements are connected by coupling element. The coupling element can be a curved strut shape that maintains the tubular elements in a spaced apart, generally parallel relationship. In alternate embodiments, tabs extend from the first end of the tubular elements and are elongated in the direction toward the second end. The tabs may be attached to the first end, or extend from tab supports that extend radially from the first ends.The user inserts the tubular elements into the nasal passages to increased airflow through the nasal passages during sleep.
