The MOU:
•
monitors and controls system operation during treatment.
•
verifies operation of the transducer and the MOU and
monitors the MOU battery for a low battery condition.
•
controls the duration of the 20-minute treatment period.
•
monitors for the presence/absence of coupling gel on
the transducer surface. The MOU then alerts you
with a visual and an audible beeping sound if gel is
not present on the transducer.
•
automatically shuts off the device at the end of the
20-minute treatment period, and alerts you with an
audio signal that treatment has ended.
•
maintains a complete record of your daily use of the
device.
•
monitors compliance with prescribed treatment
usage.

The Transducer:
The transducer is powered by the
MOU battery supply and is connected to the MOU by
a permanently attached flexible coil cable capable of
extending from 1.5 feet (45 cm) to approximately 5
feet (1.5 m). The round, flat, black transducer surface
attached to the coil cable transmits the low intensity
ultrasound signal to the skin at the fracture site
through a layer of ultrasound coupling gel. Coupling
gel is necessary, as air will not transmit ultrasound.
c.
Snap-on Cap with Tether:
For In-Cast, On-Cast,
and Non-Cast applications, the snap-on cap with a
tethering ring is used to hold the transducer in place
within the RAF. The snap-on cap has a spring
attached to its inner side that keeps a light pressure
on the transducer, thereby ensuring contact of the
transducer surface with the skin. The tethering ring
attached to the cap is placed around the RAF
opening and prevents the possible loss of the
snap-on cap.
