Method for iontophoretic treatment
First Claim
Patent Images
1. A method of minimizing vesicle formation while applying iontophoretic treatment to a living body, said method including the steps of:
- conducting direct current through the skin of said body in a first direction from a first electrode to a second electrode on said skin;
intermittently reversing the polarity of said electrodes to cause direct current to flow in a second direction opposite said first direction; and
controlling the flow of said current in said first and second directions so that the energy applied in said first direction exceeds the energy applied in said second direction by a ratio of between about 2;
1 and 7;

Abstract
A method and apparatus for applying iontophoretic treatment to a living body is provided by which a unidirectional treatment current is periodically interrupted by a relatively short pulse of current in the opposite direction in order to prevent the formation of undesirable vesicles and bulla in the skin being treated. The apparatus and method are arranged to impose the treatment current gradually at the beginning of each treatment.
