Eartips

Eartips are the parts that fit into your ear. They should fit snugly, sealing out ambient noise and helping you to focus on auscultation. All 3M™ Littmann® Stethoscopes are fitted with snap-tight, soft-sealing eartips.

Headset

The headset is made up of two eartubes, the yoke and the eartips. 3M™ Littmann® Stethoscope headsets can be adjusted to ensure a proper fit into your ear canals by squeezing or pulling apart the eartubes.

Eartube

Sound travels from the chestpiece through flexible tubing and then through the metal eartubes. 3M™ Littmann® Stethoscope eartubes are made of an aerospace aluminum alloy that provides both strength and lighter weight.

Tubing

Tubing provides the path for sound. 3M™ Littmann® Stethoscopes feature improved resistance to skin oils and alcohol for longer tubing life

Chestpiece

The chestpiece is placed on the patient to capture sounds. Some 3M™ Littmann® Stethoscope models have a one-sided chestpiece with a tunable diaphragm. Others have a two-sided chestpiece with a diaphragm on one side and a bell on the other.

Dual-lumen tubing

3M™ Littmann® Cardiology Stethoscopes have dual-lumen tubing: two sound paths inside one outer tube which helps eliminate the rubbing noise generated by traditional twin-tubed stethoscopes.

Stem

The stem connects the stethoscope tubing to the chestpiece. On 3M™ Littmann® Stethoscopes with two-sided chestpieces, the stem is used to index, or open, the side of the chestpiece that you wish to use.

Tunable diaphragm

A tunable diaphragm is a 3M invention that lets you easily switch between hearing high- and low-frequency sounds simply by adjusting the pressure on the chestpiece.
