ABSTRACT:
A device for establishing and maintaining an airway through the nasal passages. The device is a clip of unitary construction with a proximal "UU" shaped dilating portion adapted to be inserted within the nostrils; the "U's" being connected to one another medially by an elastically deformable extension portion, the extension portion being two straight parallel strips, one end of the strips being integral with the dilating portion and the opposing end of the strip integral with an arcuate septum attachment portion. The septum attachment portion spaces the distal ends of the strips of the extension portion so that the strips straddle and gently squeeze the nasal septum. The device provides maximum air flow through the nostrils. The device is attached to the nose by means of the distal elastically deformable septum attachment portion which is adapted to anatomically conform to and releasably engage the inferior margin of the nasal septum. The extension portion supports and stabilizes the proximal dilating portion within the nose. The length of the extension portion limits the distance the dilating portion extends within the nostrils and presents smooth, parallel flat septum contacting surfaces which press against and are stabilized by the opposing interior walls of the nasal septum. The proximal dilating portion of the device consists of two "U" shaped strips, each strip being affixed to a proximal open end of the "U" shaped extension portion and at right angles to the plane of the extension portion. The dilating portion presents a smooth outer tissue-contacting surface which urges against the inner surface of the walls of the nostrils forcing them outwardly. The tissue-contacting surface may include a medicament dispensing coating.
