4. The strap should be tightened, utilizing the
adjustable fastener to prevent the RAF from sliding
out of place. It should not be so tight as to cause
discomfort (
Figure 12
).
5. The strap assembly must be secured in place over
the treatment site (
Figure 11
) BEFORE the transducer
with gel applied is inserted into the RAF. This will
ensure that the coupling gel on the transducer is
applied directly to the treatment site.
6. Follow directions provided in Section F.1.c. and F.2.
for starting a treatment. You should remain in a
resting position, as much as possible, during a
treatment period to minimize movement of the
transducer and RAF Strap/Cap assembly.
b.
At the End of a Without-Cast Treatment Period:
1. Open the cap and remove the transducer from the
RAF Strap Assembly to allow for proper cleaning.
2. Remove the RAF Strap Assembly and gently clean
the skin at the treatment site to remove any coupling
gel using a soft tissue, paper towel, or cotton swab.
3. Clean any gel residue from the RAF Strap
Assembly (
Figure 13
).
4. Clean any coupling gel from the transducer with a
soft cloth, tissue or paper towel, to prevent gel
