Patent number: 8563447Abstract: Wound care devices having a topically applied silver-based antimicrobial finish are provided. The finish comprises at least one silver ion-containing compound and at least one binder compound. The finish may be applied to a target substrate, such as a fiber, fabric, film, foam, hydrogel, or hydrocolloid to provide a single layer antimicrobial wound care device. Alternatively, a silver-containing layer may be combined with one or more additional layers of target substrate to provide a composite antimicrobial wound care device. The device may also contain an odor-absorbing component capable of reducing or eliminating odors that are inherently associated with infectious wounds. Also provided is a method for making the wound care device and a composition of matter comprising the silver-based antimicrobial finish.Type: GrantFiled: August 14, 2003Date of Patent: October 22, 2013Assignee: Milliken & CompanyInventors: T. Andrew Canada, Robert L. Schuette, Raymond C. Sturm, Kenneth M. Wiencek, Jason L. Kreider

Patent number: 8460698Abstract: A composite article comprises a fluid transport layer having first and second surfaces and a hydrophobic layer applied to the first surface of the fluid transport layer. When the composite article is used as a wound dressing, the first surface of the fluid transport layer provides a skin-facing surface. The hydrophobic layer comprises a plurality of discontinuities, and at least a portion of the discontinuities have a dimension sufficient to permit the passage of fluid through the hydrophobic layer and into the fluid transport layer.Type: GrantFiled: July 2, 2009Date of Patent: June 11, 2013Assignee: Milliken & CompanyInventors: Robert M. MacMeccan, Le Zhang, Keith A. Keller, Martin E. Cowan, T. Andrew Canada

Patent number: 8454990Abstract: A composite article comprises a fluid transport layer, a fluid retentive layer, and, optionally, a moisture vapor permeable film. The first surface of the fluid transport layer provides a fluid contacting surface. The fluid retentive layer is positioned so that the first surface layer of the fluid retentive layer is adjacent to the second surface of the fluid transport layer. The moisture vapor permeable film is positioned so that it is adjacent to the second surface of the fluid retentive layer. The composite article is suitable for use as a wound dressing.Type: GrantFiled: July 2, 2009Date of Patent: June 4, 2013Assignee: Milliken & CompanyInventors: T. Andrew Canada, Martin E. Cowan, Robert M. MacMeccan, Le Zhang

Patent number: 8394403Abstract: This disclosure relates to wound care devices which are capable of one-way, directional flow of fluids and contaminants away from the wound site to the opposite side of the wound care device, which functions as a fluid reservoir. This fluid transport mechanism generally aids in reducing wound maceration by removing excess fluid, and potentially even bacteria, and is carried out without loss of physical integrity of the wound care device itself. In addition to providing a uni-directional fluid transport mechanism, the wound care device may contain a topically applied silver-based antimicrobial finish which provides certain levels of antimicrobial agent to the wound in order to clear infection from the wound site and control bacterial growth in the wound care dressing. Exemplary topical antimicrobial finishes include silver ion-releasing compounds.Type: GrantFiled: July 21, 2011Date of Patent: March 12, 2013Assignee: Milliken & CompanyInventors: T.

Publication number: 20100030170Abstract: This disclosure relates to a substrate comprising multiple layers which are designed to provide moisture absorption, non-adherence, and antimicrobial properties to a contact surface. The substrate is minimally comprised of (a) at least one skin contact layer of apertured hydrophobic polymeric film, (b) at least one layer of absorptive material that contains a reinforcement material, and (c) at least one layer of liquid impermeable film backing. The substrate may also include a layer of material that contains an antimicrobial agent. The substrate may be ideally suited for use in the medical field as an absorptive pad for end-uses such as wound care (e.g. burn care), surgery care, and incontinence care.Type: ApplicationFiled: July 2, 2009Publication date: February 4, 2010Inventors: Keith Alan Keller, T.
