ULTRASOUND WARNINGS (CONT .)
• Moving technique of the applicator should be used when applying
therapeutic ultrasound at intensities greater than 0.5 W/cm² to assure
even exposure of tissues to ultrasound.
• Heating of the joint capsule in acute or subacute arthritis should be
avoided.
• Additional precautions should be used when ultrasound is used on
patients with the following conditions:
1. Laminectomy, i.e., when major covering tissues have been removed
2. Over anesthetic areas
3. On patients with hemorrhagic diathesis
• Ultrasound should be routinely checked before each use to determine
that all controls function normally. Especially if the intensity control
does properly adjust the ultrasonic power output in a stable manner.
Also, determine that the treatment time control does actually terminate
ultrasonic power output when the timer reaches zero.
• Use the ultrasound applicator with care. Inappropriate handling of the
ultrasound applicator may adversely affect its characteristics.
• Before each use, inspect the ultrasound applicator for cracks, which
may allow conductive fluid to seep through.
• Ultrasound therapy is not designed to be water tight. Entrance of water
or liquid could cause malfunction of internal components and therefore
create risk of severe injury to the patient.
• Any bleeding tendency is increased by heating because of the increase
in blood flow and vascularity of the heated tissues. Care, therefore,
should be used in treating patients with therapeutic ultrasound who have
hemorrhagic diathesis or bleeding disorders.
• Do not use a conductive medium with an alcohol based content.
CAUTION
CAUTION WHILE USING THE STIMULATOR:
• If the stimulator is not functioning properly or the patient feels
discomfort, immediately stop using the device.
• Do not use for any other purpose except for what it is intended for.
• Do not pull on the electrodes or lead wires during treatment.
• Patients should remove all metal accessories (i.e. necklace, watch,
ring(s), etc.) prior to administering therapy as these items may cause
damage to the device.
• Do not use near a cell phone as this may cause the stimulator
to malfunction.
• Do not bend or pull the end of the cord.
• When pulling out the cord from the device, hold the plug and pull.
• Replace the lead wires when broken or damaged.
• Dispose of the device, batteries, and components according to
applicable legal regulations. Unlawful disposal may cause
environmental pollution.
• The size, shape and type of electrodes may affect the safety and
effectiveness of electrical stimulation. Please read instructions for
which electrodes should be used (specifically for combination therapy
and High Volt).
• The electrical Performance characteristics of electrodes may affect the
safety and effectiveness of electrical stimulation.
• Using electrodes that are too small or incorrectly applied, could result
in discomfort or skin burns.
• Keep yourself informed of the contraindications.
• DO NOT operate this unit in an environment where other devices are
being used that intentionally radiates electromagnetic energy in an
unshielded manner.
