Publication number: 20140257212Abstract: A system for stimulating the healing of tissue comprises a porous pad positioned within a wound cavity, and an airtight dressing secured over the pad, so as to provide an airtight seal to the wound cavity. A proximal end of a conduit is connectable to the dressing. A distal end of the conduit is connectable to a negative pressure source, which may be an electric pump housed within a portable housing, or wall suction. A canister is positioned along the conduit to retain exudates suctioned from the wound site during the application of negative pressure. A controller for automated oscillation of pressure over time is provided to further enhance and stimulate the healing of an open wound. A power management motor control for varying pump drive frequency and managing a portable power supply is provided to increase battery life and improve patient mobility.Type: ApplicationFiled: May 20, 2014Publication date: September 11, 2014Applicant: KCI Licensing, Inc.Inventors: Thomas A. Boynton, Teryl Blane Sanders, Keith Patrick Heaton, Kenneth William Hunt, Mark Stephen James Beard, David M. Tumey, L. Tab Randolph

Publication number: 20120283672Abstract: A wound treatment device comprises a polyurethane or polyether foam pad, adapted for insertion substantially within a wound cavity; a pump for supplying fluid flow to the wound site; and a collection canister for receiving wound fluids drawn from the wound cavity. The foam pad, pump and collection canister are in fluid communication with one another through a single hospital grade hose having a plurality of tiny apertures in the portion that is central to the foam pad. These apertures are adapted to allow fluids from the wound cavity to be drawn into the flow from the pump to the canister according to Bernoulli's theorem.Type: ApplicationFiled: June 8, 2012Publication date: November 8, 2012Inventor: L. Tab Randolph

A proximal end of a conduit is connectable to the dressing. A distal end of the conduit is connectable to a negative pressure source, which may be an electric pump housed within a portable housing, or wall suction. A canister is positioned along the conduit to retain exudates suctioned from the wound site during the application of negative pressure. A first hydrophobic filter is positioned at an opening of the canister to detect a canister full condition. A second hydrophobic filter is positioned between the first filter and the negative pressure source to prevent contamination of the non-disposable portion of the system by exudates being drawn from the wound. An odor filter is positioned between the first and second hydrophobic filters to aid in the reduction of malodorous vapors.Type: ApplicationFiled: August 25, 2010Publication date: January 27, 2011Inventors: Thomas A. Boynton, Teryl Blane Sanders, Keith Patrick Heaton, Kenneth William Hunt, Mark Stephen James Beard, David M. Tumey, L. Tab Randolph

Publication number: 20100121230Abstract: A method and apparatus for providing concurrent applications of intermittent pneumatic compression therapy and vacuum assisted closure therapy generally comprises a wound dressing for introduction of a negative pressure into a wound on a patient's foot and a foot wrap for application of positive, compressive forces to substantially all of the patient's foot. A suction pump, having an associated vacuum sensor and first feedback mechanism, supplies negative pressure to the wound dressing. A ventable source of pressurized gas, having an associated pressure transducer and second feedback mechanism, supplies positive force to the foot wrap. At least one control system is operably associated with the suction pump and ventable source of pressurized gas for controlling the negative and positive applications of pressure to the patient's foot. Controlled modes for operation include continuous or intermittent application of one or both therapies and simultaneous or cycled application of the therapies.Type: ApplicationFiled: November 12, 2009Publication date: May 13, 2010Inventors: Richard C. Vogel, David M. Tumey, Susan P. Morris, L. Tab Randolph

Patent number: 6488643Abstract: A medical wrap for the promotion of diabetic and like wound healing generally comprises a multi-layered sheet structure for removable application to a patient's foot, said sheet structure having interposed therein an integral bladder; an inlet for fluid inflation of said bladder; and said sheet structure being adapted and said bladder being shaped to produce a non-shearing compressive force in the area of the patient's first and fifth metatarsal heads upon fluid inflation of said bladder. The multi-layered sheet structure may comprise a first sheet and a second sheet, said first sheet forming the exterior of said structure and said second sheet forming the interior of said structure, said second sheet being more extensible than said first sheet. A padding layer of ester foam, or the like, may also be incorporated into each sheet.Type: GrantFiled: October 8, 1998Date of Patent: December 3, 2002Assignee: KCI Licensing, Inc.Inventors: David M.
