Disposable electrode for monitoring a patient

Claim 1

A nonmetallic disposable inexpensive electrode, mainly intended to be rapidly fixed on the skin of a patient to achieve noise-free signal detection of signals from the body and including an electrically conductive synthetic resin carrier element, one side of which is provided with an electric contact which is in conductive contact with the carrier element and the other side of which is provided with an adhesive layer and forms the front surface of the carrier element intended to adhere in electrical contact to the skin, wherein the adhesive layer of the front surface of the carrier element has at least one opening wherein is applied a carbon-containing element directly contacting the material of the carrier element, said carbon-containing element is a plate of carbon fibers with carbon fiber ends projecting from the surface of said plate as brushes carrying a relatively large number of carbon particles which facilitates the ion migration between the skin and the carrier element whereby the resistance between the skin and the carrier element is substantially reduced by the interposed carbon fiber plate.
