Electrode system

Claim 1

An electrode system for supplying electric signals to a body surface of a patient, said system comprising an electrode arrangement including a housing, electrode contact means supported by said housing for emplacement in conforming relation to the body surface of the patient for supplying electrical signals to the patient, and electrical line means electrically connected to the electrode contact means and leading from the housing for electrical connection with an interference current apparatus, or the like, said electrode arrangement having an extended area frontal face for disposition in confronting conforming relation to the body surface of the patient, the housing being an extended area flexible generally flat formed layer of electrically insulating plastic; said electrode contact means comprising flexible electrically conductive layers of extended area generally flat configuration having extended area interior surfaces within the housing and extended area exterior surfaces disposed exterior to the housing and separated by a thickness dimension from the extended area interior surfaces; flexible wire webs of electrically conductive material and of generally flat extended area configuration and of area substantially corresponding to the area of the interior and exterior surfaces and being embedded at the interior surfaces so as to be separated from said exterior surfaces of said flexible electrically conductive layers, said flexible wire webs being connected with said electrical line means such that electric signals are supplied from the electrical line means to the wire webs and from the wire webs through the thickness dimension of the flexible electrically conductive layers to substantially the entire area of the exterior surfaces of said flexible electrically conductive layers; said flexible electrically conductive layers (3-5, 11-13) being of material sealable with said electrically insulating plastic and being embedded flatwise in said generally flat formed layer (2, 10) of said electrically insulating plastic in such a fashion that the exterior surfaces of the flexible electrically conductive layers and adjacent surfaces of the generally flat formed layer of said electrically insulating plastic are continuously sealed to each other at their boundaries and such that said electrode arrangement as a whole has a substantially constant flexibility over the entire extent thereof which is to be conformed to the body surface.
