Littmann Stethoscope Spare Parts Kit - Master Cardiology Stethoscopes
3M™ Littmann® Stethoscope Spare Parts Kit for the Master Cardiology™ Stethoscope contains a black rim and tunable diaphragm for chestpiece, in addition to two small (1/2 inch), black or grey 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.
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.
