Abstract
A negative pressure wound therapy (“NPWT”) dressing is formed from a transparent polymer and includes large-diameter passageways through the dressing for providing suction and irrigation to a wound. The NPWT dressing is formed so as to be non-compressible and non-collapsible to provide low resistance and maintain positive surface pressure at low vacuum settings. The NPWT dressing includes a docking port and suction dome for coupling the dressing to a suction source and an irrigation source. The NPWT dressing may be customizable, disposable, and/or expandable to treat a variety of wounds.
