Abstract

A wound care electrode including a flexible, electrically conductive body and an electrically conductive gel layer secured to the bottom of the electrically conductive body for releasably coupling the electrically conductive body with the skin of a user. A flexible, nonconductive, separating layer is secured to the top of the electrically conductive body. A flexible, absorbent dressing is secured to the top of the separating layer. The electrically conductive body, the electrically conductive gel layer, and the separating layer have axially aligned perforations for conveying seepage from the skin of a user to the absorbent dressing.
