3m Littman Stethoscopes Reviewed
The 3m Littman stethoscope was invented In 1963 by,
Harvard Medical School Professor David Littmann,
a renowned cardiologist. His invention would
revolutionize the world of medicine.
The 3m Littman stethoscope that is worn by health
professionals, may look simple, but it an intrument
of quality and brillant invention. The Littman
Stethoscope is pre-eminent among all the brands
of stethoscopes, and has been the choice of
doctors and nurses worldwide.
Stethoscope design had changed little for over
a hundred years. However, Littmann realised that
the requirements for listening to low and high pitch
sounds were very different. So he patented his dual
sided stethoscope which had a chest piece with an
open side for listening to low pitch sounds and
a closed side which filtered out lower sounds.
Some of the most popular 3m littman stethoscopes are:
1. Black tube, 28 inch (71,1cm) Classic II S.E. Stethoscope.
The 3M Littmann Classic II S.E. Stethoscope features a
patented tunable diaphragm on one side, augmenting the
traditional bell function of the opposite side.
The patented tunable diaphragm alternates between bell
and diaphragm modes with a simple pressure change on
the chestpiece.
2. Black tube, 27 inch (69cm) Cardiology III Stethoscope.

conveniently alternate between low and high frequency
sounds without turning over the chestpiece.
