Expendable electro-cardiograph electrode
First Claim
1. An expendable electrode for electrocardiographic measurements comprising a thin pliable metallic sheet-like carrier member adaptable to flexibly conform to the shape of the body part on which it is to be applied and having means for attachment of means for conducting signals from said carrier member to electrocardiographic equipment, said carrier member having one side adapted to be applied to the body part and another side facing away therefrom, said one side being provided with a plurality of regularly distributed spikes devised to penetrate into the skin and a coating of an adhesive compound adapted to adhere to the body, said coating and spikes being completely covered by at least one pull-off protective foil thick enough to entirely embed said spikes.

Abstract
An expendable electrode for electro-cardiographs comprising a thin metallic carrier member coated on the surface to be applied to the skin with an adhesive and having a plurality of metallic contact spikes projecting from the coated surface which spikes are devised to penetrate into the skin. The coated and spiked surface is covered by at least one pull-off foil protecting same together with the spikes against environmental influences. On the carrier member, a transverse upwardly directed flange is provided for attachment to an electrocardiographic apparatus. A method of manufacturing the expandable electrode according to the invention is also disclosed.
