Abstract
The signal conducting element of a medical electrode of the type bridged to skin by electrolyte and which may be X-ray transparent comprises a thin layer of a conductive paint adhered to a relatively thin supporting substrate, said substrate with adhered paint extending remotely from the electrolyte-to-skin interface for circuit connection. The electrolyte may be loaded in a sponge engaging the paint or may be in a conductive adhesive layer applied to the substrate. The electrode may also have a second and more aggressive adhesive for skin attachment. A method for producing assemblies of interconnected electrodes is also described.
Claims4
In a medical electrode of the type having a conductor and electrolyte means comprising a couductive adhesive for providing an electrolyte between said conductor and the skin of a patient and for adhering said electrode to the skin, the improvement wherein said conductor comprises a sheet of flexible material and a conductive paint adhered to one face of said sheet, wherein said conductive adhesive forms a layer engaging said sheet, in overlying relationship to at least a portion of said paint, and wherein said electrode further comprises a layer of patient adhesive means on said one face of said sheet which is more aggressive than said conductive adhesive for adhering the electrode to the skin for a longer period of time or with greater security than is possible with said conductive adhesive alone.
