Abstract
An external nasal dilator comprises resilient and engagement elements, and includes end regions adapted to engage tissues overlaying and adjacent first and second nasal passages of a human nose. Each end region includes a plurality of resilient spring finger components separated therebetween by engagement element tab extensions. The end regions are further adapted to extend around the anatomical depression formed by the alar crease adjacent each nostril. When in use the dilator stabilizes or expands said tissues and prevents or inhibits the nasal outer walls from drawing inward during breathing.
Claims11
A nasal dilator comprising:
- an engagement element comprising at least one engagement layer having a peripheral edge, the peripheral edge defining an intermediate region and opposing end regions including tab extensions thereof, the intermediate region having a greater length than either end region;
- a resilient element capable of providing spring biasing forces, the resilient element comprising at least one mid-section and a plurality of spring fingers extending horizontally outward from each end of the at least one mid-section, the plurality of spring fingers numbering at least three spring fingers;
- wherein the at least three spring fingers are interposed between four separate and distinct tab extensions;
- wherein terminal ends of the spring fingers terminate along portions of the at least one engagement layer peripheral edge;
- wherein the resilient element is bilaterally symmetric;
- and
- wherein a first centerline of a first spring finger intersects a second centerline of a second spring finger at an intersection point, said intersection point lying in a lateral-most one-fourth to one-third of the resilient element.
