| 20120089068 | Silver-Embedded Foam Dressing - A dressing that comprises a contact layer for contacting a wound, with the contact layer including silicone; a foam-based hydrophilic middle layer that carries a metal-based antimicrobial agent; and a backing layer that prevents moisture within the dressing from escaping into the air through evaporation. Silicone in the contact layer interacts with the wound to minimize the appearance of scar tissue. Moisture, either applied beforehand or from the wound exudate, travels through the porous contact layer into the foam middle layer. There, the moisture acts to release metal ions from controlled-release mechanisms, such as zeolites containing the metal ions. The ions then travel within the moisture into the wound, where they act to kill bacteria and other infectious microorganisms and to prevent infections from gaining a foothold. Many embodiments, for the metal-based antimicrobial agent, use silver ions or a combination of silver ions and other metal ions. | 04-12-2012 |
| 20120071807 | Silver-Silicone Antimicrobial Dressing - An antimicrobial dressing comprising a hydrophobic, porous, meshy, silicone-coated contact layer and a fibrous substrate layer that carries and releases a metal-based antimicrobial agent to prevent infection. In some embodiments, the contact layer comprises a mesh of silicone-coated polyethylene fibers. The silicone in the contact layer helps to reduce the appearance of scars as wounds heal. In some embodiments, the substrate layer comprises a fibrous mesh in which some or all of the fibers are coated in a zeolite carrying metal ions. When the dressing encounters moisture, and moisture penetrates to the substrate layer, the moisture acts to release the antimicrobial metal ions from the zeolites. The ions then migrate through the porous, meshy contact layer into the wound, where they kill microorganisms that cause infection. In some embodiments, the antimicrobial ions carried in the substrate layer are silver ions; or a mixture of silver ions and copper ions; or a mixture of silver ions and zinc ions; or a mixture of silver ions and sodium ions. | 03-22-2012 |
| 20100247613 | Dressing Modified to Receive Medicine - A laminated dressing defining an area adapted to receive and hold medicine. In one embodiment of the invention, the dressing comprises a contact layer and a backing layer, both fabricated from absorbent materials. The contact layer has an inboard surface and an opposing outboard surface defined. The outboard surface of the contact layer is adapted to be applied to a patient's skin surrounding a wound. The contact layer further defines a die-cut through-opening substantially in the center of the contact layer. Adhering to the inboard surface of the contact layer is the backing layer, which likewise has an inboard surface and an opposing outboard surface defined. Medicine is received in the area defined by the through-opening in the contact layer and the inboard surface of the backing layer. A polymer film covers the outboard surface of the backing layer to prevent the escape of medicine from the dressing through the backing layer. A removable release film covers the adhesive-covered outboard surface of the contact layer, the reception area and the medicine until the dressing is ready to be used. | 09-30-2010 |
