ABSTRACT:
A thin, disposable shield serves as a sanitary cover as well as a diaphragm for a stethoscope. The shield has a circular line of perforations, resulting in a central disk portion and an outer ring portion. The shield is releasably secured to the rim, preferably by adhesive, to protect a patient from contact with the rim. The shield itself serves as the diaphragm, vibrating with sound transmission. The perforations optionally allow the disk portion to be punched out to provide an unobstructed path for sound transmission of lower frequency. If the forward face of the threaded ring of a conventional stethoscope is not flat, a substitute ring may be secured in place of the conventional ring. The substitute ring has a flat face that is perpendicular to the longitudinal axis. The flat face enhances the ability of the shield to stick to the ring.
