Abstract
A multipolar medical electrode for attachment to the skin of a patient for deriving separate electrical signals from spaced locations indicative of physiological activity is provided. A flexible pad of nonconductive material has a pair of well members which each contain an electrolytic gel to make contact with the patient's skin when an adhesive backing is removed. An electrical connector for connecting the electrode pad to an electrical potential measuring instrument includes a nonconductive body having a pair of spaced conductive prongs connected by wires to the electrical potential measuring instrument. The prongs are inserted respectively through a puncturable membrane in the respective well members, making intimate contact with the electrolytic gel and have a generally box-shaped housing attached to the nonconductive body protects the prongs and slidably engages the outer surfaces of the well members to assist in guiding the prongs into the well members.
