Nasal stethoscope
Abstract:
A nasal stethoscope including a nostril tube for insertion into a human nostril, a spring-type clip affixed to the nostril tube, and a pad affixed to a first jaw member of the spring-type clip. The spring-type clip is movable between a closed position and an open position. The pad is interposed between the nostril tube and the first jaw member. A connector tube is affixed to an end of the nostril tube opposite an open end of the nostril tube. An earpiece tube can be removably connected to an end of the connector tube opposite the nostril tube. The clip has a second jaw member directly affixed to an outer surface of the nostril tube. The clip extends in generally parallel relationship to a longitudinal axis of the nostril tube. The first jaw member has an arm extending outwardly therefrom so as to move the clip from the closed position to the open position. The first and second jaw members have tapered ends narrowing toward an end of the nostril tube.
