Welch Allyn® Introduces Master Elite™
Stethoscope with Patented Sensor Technology
New Stethoscope Uses Meditron® Sensor-based
Technology to Improve Doctor’s Ability to Detect Faint Sounds
Welch Allyn, Inc., one of the world’s leading manufacturers
of medical diagnostic instruments and patient monitoring systems,
today announced the introduction of the Welch Allyn Master Elite
Stethoscope. This innovative new product utilizes patented Meditron
sensor technology that reduces the effect of ambient noise and
resonance associated with conventional stethoscopes, making it
easier for doctors to hear faint crackles, wheezes, low diastolic
murmurs, or high-pitched pulmonary sounds.
The Welch Allyn Master Elite Stethoscope includes a highly sensitive
sensor with a frequency range of 20-20,000 hertz and an excellent
signal-to-noise ratio. There is a two-position frequency selection
switch that makes it possible to focus specifically on either
high (diaphragm mode) or low (bell mode) frequencies. In addition,
there is a variable volume control selector that offers powerful
amplification, even in noisy environments.
“The patented sensor technology used in the Master Elite
is similar to technology used to detect submarines deep in the
sea,” said Lari Shreffler, associate product manager at
Welch Allyn. “Contrary to other electronic stethoscopes
that use a microphone, the Master Elite allows healthcare practitioners
hear more of the sounds they need, and less of the sounds they
Optional analyzer software enables the audio signal to be transferred
to a PC where the sound can be stored and replayed as required.
The recording can be saved in the patient’s record and compared
with later recordings. The analyzer software can also convert
sound files into graphic representations. In addition, a distributor
unit is also available that allows several stethoscopes to be
linked together so that a number of people can listen to the same
patient simultaneously. This “co-listening” ability
is a key feature that helps in consultation or teaching situations.
The Welch Allyn Master Elite weighs only 16 ounces and its adjustable
binaurals and ear tips provide all-day comfort.
