Abstract
A diagnostic electrode adapted to be affixed to a patient's body for diagnostic medical tests comprising a foam backing layer coated with an adhesive, a tin foil layer bonded to said backing layer and a conductive gel coated on a portion of the tin foil layer. The tin foil layer is of a smaller size than the backing layer and is oriented thereon such that the backing layer forms a U-shaped border around the tin foil layer, to thereby supplement the conductive gel in affixing the electrode to the patient's body. The foam backing layer further provides a surface which a clip, electrically coupled to diagnostic equipment, can securely bite into, in order to securely grip the electrode. A plurality of electrodes are arranged on a release web with their clip tabs intermeshing in side-by-side relation, and extending over a central fold line in the web whereby when the web is folded, the clip tabs are exposed for ease of grasping or securing a lead clip.
