Claim:
1. An electrically, elongatable conductive medical glove comprising: an electrically insulated elastic glove body having an inner surface for intimately contacting a portion of a user's hand and an outer surface, wherein the material for the electrically insulated elastic glove body is selected from the group consisting of latex, nitrile, polyisoprene, polychloroprene, and vinyl; a portion of the outer surface of the glove body has an integral electrically conductive elastic coating, the integral electrically conductive elastic coating comprises a solvent-based polymer having electrically conductive flakes (i) wherein each flake has an average flake size between 5 and 15 microns, and (ii) positioned in the solvent-based polymer to remain conductive at 50% of stretch for the electrically insulated elastically expandable glove body, the integral electrically conductive elastic coating is on the portion that is an electrically, elongatable conductive path, the elasticity of the coating being selected to functionally match the elasticity of the electrically insulated elastic glove body; a water-based protective elastic coating, wherein a portion of the electrically, elongated conductive path is covered by the water-based protective elastic coating and maintains full integration with the electrically insulated elastic glove body to the elastic limit of the electrically insulated elastic glove body while being adapted to recover its initial shape when relaxed; wherein the electrically, elongatable conductive path maintains full integration with the electrically insulated elastic glove body to the elastic limit of the electrically insulated elastic glove body while maintaining conductivity after donning the electrically insulated elastic glove in an elastically expanded state wherein at least a section of the electrically, elongatable conductive path is capable of being elongated between 100 and 250%, the electrically insulated elastic glove body thereby capable of recovering its initial shape when the electrically insulated elastic glove body is relaxed; where the elasticity of the integral electrically conductive elastic coating is functionally equivalent to the elasticity of the electrically insulated elastic glove body; wherein the electrically, elongatable conductive path maintains full integration with the electrically insulated elastic glove body and remains continuously conductive while elongated with a resistivity below 2000 Ohms and is capable of recovering its initial shape; wherein the solvent-based polymer used in the integral electrically conductive elastic coating is styrene and the integral electrically conductive elastic coating further comprises a dispersant agent; and the water-based protective elastic coating is urethane.
