Abstract

A medical electrode and skin preparation device is adapted to be secured to the skin of a patient and is designed to prepare the skin by abrasion or penetration of the epidermal layer of the skin in contact with the conductive means of the electrode after the electrode is secured in place on the skin. The electrode includes a penetrating device associated with a conductor capable of transmitting biopotential events for recording, with the conductor being retained by an adhesive member which secures the electrode to the skin of the patient. The penetration device in contact with the skin is movable relative to the skin of the patient and a holder by an applicator gun to abrade or penetrate the epidermal layer of skin after the electrode is placed on the skin. Uniform skin preparation is achieved by a flexible screen member and an electrolyte gel reservoir on the electrode and an applicator gun which minimizes motion artifacts arising from skin potential variations.
