3M™ Littmann® Stethoscope Spare Parts Kit for the Classic II S.E. stethoscope contains a rim and tunable diaphragm for the adult side of the chestpiece and a non-chill rim for the bell side of the chestpiece. Also included are two small (1/2 inch), 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 the patient, while the non-chill diaphragm provides patient comfort.
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.
Replacement of eartips, nonchill bell sleeve and tunable diaphragm on Classic II S.E. stethoscopes.
