The gel is dry and losing its stickiness.
Even when the electrode seems to be losing its
adhesion to the skin, it should still be usable; the
band will help to keep contact with the skin.
The electrodes should last approximately 2 weeks
with typical use. Be sure to store electrodes
properly between uses as described in Chapter 7
of the User Manual.
The gel on my electrode is coming off and/or
spreading.
The electrode should still function and can be used
safely as long as the stimulation feels comfortable
and the device does not repeatedly blink orange
during therapy sessions. Gel spread is more likely
to occur in hot, humid weather since the hydrogel
may absorb additional moisture to cause it to
expand.
How can I minimize gel spread?
Ensure that the sport band isn’t wrapped too
tightly around the leg, as that will contribute to
gel spread. Electrode shouldn’t leave an imprint on
the leg after it is removed. If it does, you need to
loosen the band slightly.
Remove the device when not in use to allow the gel
to cool.
Minimize use outdoors during hot, humid weather,
when possible.
Be mindful about where the device and electrode
are stored in hot and humid weather, i.e., a hot car.
In some cases, it may also help to alternate
between two electrodes (if you switch the device
at the 4-hour or “long-term wear” alert, for
example) to minimize the amount of gel migration
that may result from extended sessions.
Issues with hydrogel movement are much less
frequent during cooler, drier months.
What do I do if I have lost the electrode liner?
Use a piece of wax paper (plain paper will stick to
the hydrogel).
Another option is to place the electrode in a plastic
zipper bag laid flat or loosely folded (if a larger
bag is unavailable) with the gel facing out.
Gel will stick to itself if pads are allowed to touch.
Skin Care
My skin is irritated (redness or rash) or itches
where the device was worn.
Skin irritation may occur. The skin should be aired
out after wearing for 4 hours and after overnight
use by removing the device and electrode from
the leg or switching legs. If at any time the skin
begins to feel irritated (itchy) while the device is
on, device should be removed and the skin allowed
to breathe.
Consider using light skin moisturizer if skin is dry.
Ensure that the strap is not being placed too
tightly; this can cause the strap/electrode to
create indents in the skin and lead to irritation.
Alternate leg on which Quell is worn, if possible.
Reorient the device so the electrode is covering
another part of the leg, i.e., button faces in toward
the other leg or the back of the leg or the outside
of the leg.
If skin is irritated, do not place device or electrode
over the irritated area until it has fully healed.
