3M Littmann Stethoscope Spare Parts Kit for the Classic III and Cardiology IV Stethoscope contains a black, single-piece, tunable diaphragm for both the adult and pediatric sides of the chestpiece, a nonchill bell sleeve, and 2 small (1/2"), black, snap-tight, soft-sealing ear tips
Tunable diaphragm technology-a 3M invention-lets clinicians hear different frequency sounds by simply adjusting the pressure on the chestpiece by holding the chestpiece with light pressure to hear low frequency sounds and pressing harder to hear higher frequency sounds, a time-saving feature allowing the healthcare provider to focus on both adult and pediatric patients
Snap-tight, soft-sealing ear tips conform to individual ears for an excellent acoustic seal and comfortable fit, snapping firmly onto the ends of the ear tubes and, for safety, requiring a significant effort to remove
