Eartips are the parts that t into your ear.
They should t snugly, sealing out ambient
noise and helping you to focus on
auscultation. All Littmann stethoscopes are
tted with snap-tight, soft-sealing eartips.
Eartips
Eartube
Sound travels from the chestpiece through
exible tubing and then through the metal
eartubes. Littmann stethoscope eartubes are
made of an aerospace aluminium alloy that
provides both strength and lighter weight.
Headset
The headset is made up of two
eartubes, the yoke and the
eartips. Littmann stethoscope
headsets can be adjusted to
ensure a proper t into your
ear canals by squeezing or
pulling apart the eartubes.
Tubing provides the path for sound.
Littmann stethoscopes feature
next-generation tubing that provides
improved resistance to skin oils and
alcohol for longer tubing life.
Tubing
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.
The stem connects the
stethoscope tubing to the
chestpiece. On Littmann
stethoscopes with two-sided
chestpieces, the stem is used to
index, or open, the side of the
chestpiece that you wish to use.
Stem
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.
Tunable Diaphragm
The chestpiece is placed on the
patient to capture sounds. Some
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. Some
bells are always open, others are
closed with a tunable diaphragm,
depending on the model.
