Abstract
A sweat control or hyperhidrosis treatment device for providing iontophoresis of antiperspirant into a region of a human body includes a DC power source, a controller and a pair of electrodes. The electrodes are mounted in generally close proximity to one another and are separated by an insulating member. The electrodes generally carry an antiperspirant element and are responsive to an a current signal through the controller. The electrodes are generally formed of aluminum and have a rough surface to increase the number of aluminum ions available for infusion into the region. The controller converts the DC signal to an AC waveform. The electrodes are of opposite polarity with respect to each other such that during the first portion of the AC waveform, current is conducted through the region in a first direction from the first electrode to the second electrode. During the second portion of the AC waveform, current is conducted through the region in a second direction from the second electrode to the first electrode. The device further includes a pair of pads. Each of the pads is positioned in adjacent contact with one of the electrodes and preferably carries sodium salicylate to inc…
