1. In a mtehod of manufacturing a strip of disposable medical electrode pads, said strip having a release liner and plural medical electrode pads secured to said release liner, each of said electrode pads being adapted to be used with a reusable electrode pads being adapted to be used with a reusable electrode conductor, comprising the steps of:

  • providing a length of release liner in strip form;

    providing a pair of foam webs of closed cell, electrically non-conductive foam having one surface coated with a pressure sensitive adhesive;

    laying said foam webs on top of said release liner with said adhesive coatings thereon engaging said release liner, one of said webs being laid along one side of said release liner and one along the opposite side thereof;

    depositing a strip of an electrolyte gel on said release liner between said webs;

    providing a plastic sheet web of relatively stiff, electrically non-conductive, plastic sheet material having one surface coated with a pressure sensitive adhesive, and having a plurality of electrode conductor-receiving sockets spaced along its length;

    laying said plastic sheet web over said strip of electrolyte gel and in overlapping relation to both of said foam webs with its adhesive layer engaging said gel and said foam webs with said sockets overlying said strip of electrolyte gel; and

    severing said foam webs, said gel strip, and said plastic sheet web transversely between said sockets to thus form a plurality of electrodes on said release liner.
