Estimating the term…
The highly conductive hydrogels of this invention are comprised of a cohesive uniform mixture of poly(vinyl pyrrolidone), a viscosity-enhancing hydrophilic polymer, and an effective amount of an electrolyte. This polymeric mixture which is crosslinked by exposure to radiant energy provides a gel-like solid which is sufficiently tacky and adhesive to adhere to the subjects' skin and yet is substantially non-stringy and non-aggressive such that the use of such hydrogel imparts less discomfort to the user. In addition, the consumer utilizing the product of this invention would not experience the objectionable sticky, stringy sensation associated with existing conductive adhesive gels.
A highly conductive non-stringy adhesive hydrophilic gel comprising a cohesive uniform aqueous mixture of poly(vinyl pyrrolidone) (PVP), a viscosity-enhancing hydrophilic polymer having a weight average molecular weight in excess of about 100 kilodaltons (kD), and an amount of a water-soluble electrolyte effective to reduce the transverse electrical resistance of said aqueous mixture to an impedance at 60 Hz of less than about 1,000 ohms,
A conductive wound dressing comprising a conductive non-stringy adhesive hydrophilic gel, which gel comprises a cohesive uniform aqueous mixture of poly(vinyl pyrrolidone) (PVP), a viscosity-enhancing hydrophilic polymer having a weight average molecular weight in excess of about 100 kilodaltons (kD), and a sufficient amount of a water-soluble electrolyte,
