Vacuum electrodes
There is a choice of large and small electrodes. The areas of the electrodes correspond to those of the
4 x 6 cm and 6 x 8 cm flexible rubber electrodes. The vacuum electrodes are sufficiently flexible to
ensure optimum contact with the skin, but rigid enough to prevent any changes in the contour of the
part being treated, allowing full advantage to be taken of the massage effect of the pulsed vacuum.
Keep the sponge pads well moistened (close to dripping when lightly squeezed) during treatment.
Remoisten when treatment exceeds 10 minutes. After use clean the sponge pads as described under
Cleaning and Disinfection
.
Self-adhesive electrodes
Self-adhesive electrodes have higher series impedance than flexible rubber electrodes. This can cause
the stimulator to terminate treatment at higher current amplitudes. When this occurs, it is
recommended to continue the treatment with flexible rubber electrodes, combined with properly
moistened sponge pads.
Self-adhesive electrodes are not recommended for use with currents that contain a DC component.
Ultrasound therapy
Contact control
The ultrasound head has a contact control function that suspends treatment when the acoustical
contact with the body drops below a certain level. The indicator light on the ultrasound head is turned
on to signal this situation, the ultrasound channel status icon changes to pause and the treatment is
resumed at the set Amplitude.
Amplitude display will start blinking and the treatment timer will stop counting down. During this
situation, the applicator emits a small amount of energy to sense restoration of acoustical contact.
You may experience this when the ultrasound head only partially contacts the body. When contact
restoration is sensed the treatment is resumed at the set Amplitude.
Note: The contact control function does not work at Amplitudes below 0.2 W/cm².
The contact medium
Never apply the gel directly to the ultrasound applicator. The applicator will register this as
acoustical contact and may emit ultrasound energy, which could damage the applicator.
If the body surface is very irregular, making it difficult to obtain good contact between the
ultrasound applicator and the body, or if direct contact must be avoided (e.g. due to pain),
the affected area may be treated under water (subaqual method). The water should be
degassed (by previous boiling) in order to prevent air bubbles arising on the ultrasound
applicator and the body.
To ensure efficient transfer of energy, a contact medium is required between the ultrasound applicator
and the body. Air causes virtually total reflection of the ultrasound energy. The best medium for the
transfer of ultrasound energy is a gel.
The gel should be applied to the part of the body to be treated and then spread out with the
ultrasound applicator.
Vacuum
Vacuum electrodes make good contact with the skin, which means that effective use is made of the
whole electrode area. The massage effect resulting from the pulsed vacuum ensures a good blood
flow through the skin under the electrodes. This reduces the resistance of the skin and increases he
effectiveness of the stimulation current.
