Conveniently packaged in kits that correspond to our stethoscope models, Littmann stethoscope replacement parts and accessories make repairs simple. Each item is carefully manufactured to work seamlessly with existing equipment. The 3M Littmann Stethoscope Spare Parts Kit – Gray, Compatible with Classic III™, Cardiology IV™, CORE Digital, Includes Eartips, Adult & Pediatric Diaphragms, Non-Chill Bell Sleeve, 40017 contains a gray single piece tunable diaphragm for both the adult and pediatric sides of the chestpiece, a non-chill bell sleeve, and two small (1/2 inch), gray Snap Tight Soft-Sealing Eartips. Tunable diaphragm technology—a 3M invention—lets clinicians hear different frequency sounds by simply adjusting the pressure on the chestpiece. Hold the chestpiece with light pressure to hear low frequency sounds; press a little more to hear higher frequency sounds. This time-saving feature allows the healthcare provider to focus on both adult and pediatric patients. Snap-tight, soft-sealing eartips conform to individual ears for an excellent acoustic seal and comfortable fit. Eartips snap firmly onto the ends of the eartubes and, for safety, require a significant effort to remove.
