IMPROVED OSTOMY APPLIANCE
In general, the present invention is directed to systems and methods for providing ostomy faceplates in proximity to negative pressure wound devices. This may be achieved, for example through the use of an ostomy appliance or faceplate with a non-circular flange for attachment of a bag or pouch. In accordance with some embodiments, this non-circular flange may be substantially “D”-shaped, and/or have at least one substantially straight edge. In some embodiments, the ostomy faceplate may itself be noncircular and/or “D”-shaped; may include a cutting guide for cutting materials used with an NPWD; may contain an asymmetrically located aperture; and/or may comprise one or more tapered edges.
1 - 27 . (canceled)
28 . An ostomy appliance with a non-circular flange for mechanical attachment of a bag or pouch, the non-circular flange comprising at least one substantially straight edge configured to be abutted against a negative pressure wound device.
29 . The ostomy appliance of claim 28 , wherein the at least one substantially straight edge of the non-circular flange further comprises a cutting guide for cutting films, drapes, or bandages used with a negative pressure wound device.
30 . A system for reducing effluent from an ostomy leaking into a negative pressure wound device when a stoma is located near a wound, the system comprising:
a negative pressure wound dressing, comprising foam or gauze disposed adjacent to a wound, a film or drape covering the foam or gauze, and a tube providing negative pressure under the film covering;
an ostomy appliance being a wafer, barrier, or faceplate with a non-circular flange for mechanical attachment of a bag or pouch, the non-circular flange comprising at least one substantially straight edge, the at least one substantially straight edge abutted against the film or drape, such that there is no overlap between the film or drape and the ostomy appliance.
31 . The system of claim 30 , wherein the substantially straight edge of the non-circular flange further comprises a cutting guide for cutting the film or drape as close as possible to the ostomy appliance.
32 . The system of claim 30 , wherein the ostomy appliance or faceplate is comprised of an impermeable, substantially impermeable, or vapor permeable material.
33 . The system of claim 30 , wherein the ostomy appliance further comprising an aperture, configured to receive a stoma.
34 . The system of claim 30 , wherein the ostomy appliance does not include an aperture for receiving a stoma but is configured to be cuttable to reflect accurate stoma placement.
