ABSTRACT:
A flexible cuff for wrapping around a part of a limb, that is comprised of multiple patch units of a required size and shape to fit the body contour for applying to an area of skin. The cuff has an array of flexible (polymer) electrodes held at constant potential with alternating polarities. A network of supply tubes connected to an external liquid reservoir, provides a slow supply of a medicated fluid to each electrode.
An electric field applied through the cuff then causes the drug to be rapidly absorbed throughout the skin. The electrodes within the cuff, or applicator pads which it is comprised of, can be additionally be used for applying Transcutaneous Nerve Stimulation, and for Electrical Muscle Stimulation. Alternately, the cuff can be used to assist rehabilitation exercise therapy conditioning in combination with Electrical Muscle Stimulation.
