ABSTRACT:
A nasal dilator compatible with conventional illuminating devices whereby the nasal passage may be symmetrically dilated allowing for even illumination for inspection of the nasal cavity or the insertion of a specimen collection probe. Two symmetrical lever arms are spring-urged together and connected to a common base by a pair of wing-like arc springs. Compression of these springs by an inward force on the proximal ends of the lever arms urges their distal ends apart expanding the nasal passage by means of two symmetrically projecting dilating members.
