Electrodes
It is recommended that only electrodes supplied by EMS Physio Ltd. are
used with the Combination 860. Three sizes of conductive rubber electrodes
are available. These are small (70 x 50 mm), medium (100 x 70 mm) or large
(130 x 100 mm). Replacement sponge covers are available for each
electrode.
In most applications it is sensible to use as large an electrode as is practical
for the area of the body being treated. This will also reduce the possibility of
any adverse effects at the site of the electrode due to high current density.
Inspect the area to be treated to ensure there are no open wounds, areas of
infection, abrasions etc. Wash the skin in warm soapy water to minimise skin
impedance and remove any creams or gels that may have been used.
Explain to the patient what is being done and what is going to happen.
Soak the sponge electrode covers in warm water. In a soft water area it may
be necessary to add a small amount of bicarbonate of soda to the water to
ensure low contact impedance for the electrodes. Fit the rubber electrodes
fully into the sponge covers.
Apply the electrodes to the patient using the elasticated bandages supplied.
The bandages must cover the whole of the electrode and maintain an even
pressure in order to achieve a uniform current flow. A piece of polythene may
be used between the top surface of the sponge cover and the elasticated
bandage to prevent the bandage becoming wet.
Connect the electrodes to the stimulator output with the cables provided. For
DC applications the yellow lead is positive and the blue negative.
It is important to ensure that the patient feels the expected sensation in the
required area during treatment, otherwise the electrodes should be
relocated.
The electrodes must never be placed so that the stimulating current
crosses the chest or passes near the heart.
Re-useable electrodes should be cleaned and disinfected between patients.
A full range of self-adhesive electrodes is also available (see ‘Optional
Accessories’).
