System Overview - NOT AVAILABLE FOR SALE
Handheld STG™ brings computing power to stethoscopes.
Using an output of an electronic stethoscope, the STG displays the sounds
that the physician is hearing and stores them on the PDA. These lung and
heart sounds can be replayed along with a waveform visualization in the
time or frequency domain. Waveform displays reveal diagnostic information
often not heard on the auscultation. In addition, the STG software analyzes
lung sounds for the presence of abnormal sounds. Wheezes and crackles
are counted and displayed on the PDA screen. Captured sounds can be shared
with other physicians or saved for future reference. The
Handheld STG can be used as a phonocardiogram
and is also designed for the recording, replay, display and automated
analysis of lung sounds. STG is the only commercially available device
for all of these clinical uses.

Holding a chest piece by hand often generate artifacts that make visual
display unreadable. If you have this problem (and most people do), we
suggest that you attach the chest piece to skin so that you do not need
to hold it. There are several attachment methods you can use:
1. Just place the chest piece on bare skin. If the chest piece is heavy
enough it will stay in place.
2. Attach the chest piece with 3M Double Stick Discs (SKU B11687). You
can order it here: 3M Double-Stick Discs pack of 102 Size 1 1/4" 3M SAS2349 (HC) 3M 2181 (Pack).
3. Use a rubber belt to hold chest piece in place. We prefer maternity
belt used to hold a doppler monitor in place when the hospitals want to
hear the fetal heartbeat for an extended time. It's made of very soft,
pliable and stretchy material. You can order it here: www.utahmed.com,
