Abstract
A combination soft body tissue stimulator and heating device including two thin, flat, multi-layered flexible pads, each formed as a unit, one side of which defines a working surface. The working surface of each pad is defined by a very thin conductive foil layer which, when properly installed, makes electrical contact with, and receives support from, a separate disposable double-sided flexible adhesive electrode attached to the skin over the soft tissue. The electrodes adhesively attached to the skin are generally aligned with the conductive working surface so that only the adhesive attachment between each working surface and one electrode is required to hold each pad in place against the skin. A resistive heating element is layered within the pad which is generally coextensive with and electrically isolated from the working surface. A thin layer of foam or neoprene is attached against the other surface of the heating element or layer. Each conductive working surface and each heating element of each pad are connectable to a pulsed electrical current and to a d.c. battery supply, respectively, for simultaneous stimulation and heating of any desired soft body tissue area. The workin…
