Patent number: 8706183Abstract: An electrode system include a flowable and cohesive surface contact element comprising a hydrophilic polymer swollen with an electrolyte fluid, the contact element having a Q? ratio of at least 5 as defined by the equation Q ? = W W W G wherein WG is the dry weight of the hydrophilic polymer and WW is weight of water in the sample after absorption of the electrolyte fluid comprising water and an electrolyte salt. The surface contact element can consist essentially of the hydrophilic polymer swollen by the electrolyte fluid. Another electrode system includes a contact element including a crosslinked hydrophilic polymer matrix. The contact element has a Q? ratio of at least 5 as defined by the equation Q ? = W W W G . The contact elements can also have a Q? ratio of at least 6, at least 7, at least 10 or even at least 11.Type: GrantFiled: June 30, 2008Date of Patent: April 22, 2014Assignee: University of Pittsburgh-Of the Commonwealth System of Higher EducationInventors: Xinyan Cui, Nicolas Alexander Alba, Mingui Sun

Publication number: 20140100504Abstract: A hydrogel formulation is provided for use with a film. The hydrogel formulation includes a medical-grade hydrogel and an antimicrobial substance. This hydrogel formulation may be coated onto one or more surfaces of a medical-grade transparent film suitable for a wound dressing. The antimicrobial material may be a silane quaternary ammonium salt. The silane quaternary ammonium salt may comprise 3-(trimethoxysilyl) propyldimethyloctadecyl ammonium chloride. The 3-(trimethoxysilyl) propyldimethyloctadecyl ammonium chloride may constitute about 72% by weight of the silane quaternary ammonium salt. The medical-grade hydrogel may comprise a colloidal gel in which the particles are dispersed in water. Further, the hydrogel formulation may include about 0.01% to about 60% by weight of the antimicrobial substance. The transparent film may further include a release liner applied over the coated side(s) of the transparent film. The transparent film may comprise polyurethane.Type: ApplicationFiled: October 9, 2013Publication date: April 10, 2014Inventor: Patrick E. Eddy

Patent number: 8692050Abstract: A medicated patch is provided which is covered with a liner that enables one to remove the liner unconsciously and readily without losing the initial stickiness of the medicated patch. The external medicated patch includes a backing, an aqueous adhesive drug-containing matrix that is spread substantially entirely over one surface of the backing, and a liner that is larger in size than the surface of the drug-containing matrix to which the liner is attached. The liner larger in size than the surface of the drug-containing matrix to which the liner is attached includes an unattached area that extends from the surface of the drug-containing matrix, or an unattached slack portion that projects upward from the surface of the drug-containing matrix at a position on the surface of the drug-containing matrix.Type: GrantFiled: April 25, 2006Date of Patent: April 8, 2014Assignee: Teikoku Seiyaku Co., Ltd.Inventor: Masanori Uematsu

Patent number: 8690841Abstract: An improved wound care system is set forth. The system includes a wound care device having a first end and a second end. A fastener, adapted to extend to a desired length to selectively attach the device at an anchor, wherein the anchor is provided on a second end of the device is also provided. The fastener is sufficiently sized and formed of a suitable material to prevent the device from moving when secured to the anchor. In an embodiment, medicine is provided in a desired treatment area of the device. The medicine can be inserted via a medicinal delivery device by inserting the medicinal delivery device up to a stop on the medicinal delivery device into the wound care device.Type: GrantFiled: July 9, 2010Date of Patent: April 8, 2014Inventor: R.
