Applicator Movement
If movement of the applicator is too slow, the patient may feel
periosteal pain characterized by a deep ache or pain. If motion is too
fast, or if the applicator does not maintain good contact with the skin,
the therapeutic eect of the sound waves will be reduced and the
applicator may overheat.
Patient Susceptibility
Some patients are more sensitive to ultrasound output and may
experience a reaction similar to a heat rash. Be sure to inspect the
treatment area during and following treatment, and discontinue if an
adverse reaction does occur.
Coupling
Coupling is described as contact between the applicator and the
treatment site and may be accomplished through the use of a
coupling agent, such as gel, lotion. Anything used as a coupling agent
must be highly conductive. Air is a very poor conductor of ultrasonic
waves.
WARNING
1. The device complies completely with all parts of 21 CFR 1050.
10 of the performance standard for sonic, infrasonic and
ultrasonic radiation-emitting product.
2. Cautions- use of controls or adjustments or performance of
procedures other than those specified herein may result in
hazardous exposure to ultrasonic energy.
