10.2. TREATMENT LOCATIONS
Figures 4 and 5 depict examples of device
placement on two treatment locations. Figure
4A and 4B illustrates using the sam Device with
one applicator on the shoulder and knee. Figure
5A and 5B illustrates using the sam Device with
two applicators on the shoulder and knee. When
determining treatment location, consider that
the maximum diathermic effect will occur directly
under the applicator face; therefore, placing
the applicator near or directly over the target
area while following all warning and cautionary
instructions is advised.
Note: These figures are examples and are not
intended to be the suggested or only
allowable applicator configurations for those
body locations.
Warning: Do Not apply directly over a bone that is
near the skin surface.
10.3. ONE OR TWO APPLICATORS
The sam Device may be used with one or two
applicators simultaneously. The decision to use
one or two applicators is dependent on the
size and anatomical area of treatment. Using
two applicators allows a larger area of tissue to
receive ultrasound treatment. For example, large
anatomical regions, such as the shoulder could
benefit from two applicators, whereas smaller
treatment areas such as the forearm may only
require one.
10.3.1. SINGLEAPPLICATOR MODE
Connect the power controller wire to a single
applicator by inserting the power controller wire
jack into the matching cavity at the base of the
applicator. The port for the power controller wire is
described as ‘Applicator connection’ on the Power
Controller drawing shown in Figure 2, page 10.
