Abstract: A cover layer for a vacuum wound therapy dressing includes a backing layer formed from a flexible polymeric membrane and an adhesive layer for affixing the backing layer over a wound bed to provide a substantially fluid-tight seal around a perimeter of the wound bed. The cover layer is reinforced with a reinforcement layer extending to a peripheral region of the backing layer to distribute forces associated with evacuating a reservoir, as defined by or within the cover, to stimulate healing of the wound bed.

Abstract: A dressing for an open wound includes a cover layer dimensioned for positioning relative to a wound bed. The cover layer permits an evacuation of the space around the wound bed such that a sub-atmospheric pressure may be established to stimulate healing and facilitate the removal of fluid from the wound. Multiple performance zones in the cover layer allow the wound dressing to remain in position through repeated cycles of evacuation without placing undue strain on the wound bed. An outer peripheral zone may include a high peal-strength adhesive while an intermediate zone may include a shear resistant adhesive. A central zone may be devoid of any coating to maximize moisture transmission through cover layer.

Abstract: A wound dressing for use in a vacuum wound therapy treatment includes a backing layer for positioning over a wound to define a reservoir in which a reduced pressure may be maintained over the wound. A portal member affixed to the backing layer provides a connection to a reduced pressure source through an opening in an ambient surface. A primary port extends between the opening and a primary aperture in a reservoir surface to providing fluid communication between the reservoir and the reduced pressure source. At least one supplemental port establishes fluid communication between the primary port and a supplemental aperture in the reservoir surface that is distinct and substantially spaced from the primary aperture.

Abstract: An apparatus for promoting the healing of an exuding wound includes a cover layer for positioning over a wound to define a reservoir over the wound. An exudate conduit having a fibrous core includes a plurality of fibers communicates with the reservoir for wicking fluids away from the wound.

Abstract: A composite wound dressing and delivery apparatus includes a substantially transparent dressing layer having a lower surface that is coated with a pressure sensitive for applying the dressing layer over a wound to define a reservoir in which a negative pressure may be maintained. A substantially transparent backing layer adhered to the lower surface of the dressing layer in a releasable manner, and a vacuum port is centrally located on the dressing layer. The vacuum port is adapted to provide fluid communication between a vacuum source and the reservoir through the dressing layer. A targeting grid associated with either the dressing layer or the backing layer includes regularly spaced reference marks along at least two axes extending from the vacuum port.

Abstract: A wound dressing for managing wound fluids includes a porous contact layer for positioning adjacent a wound. An internal open window extends through the contact layer exposing a distal side of an absorbent member. The absorbent member is disposed in a superimposed relation to the window of the contact layer and is dimensioned to extend laterally beyond the window such that a portion of the absorbent member overlaps and is secured to the contact layer. A drape layer is disposed on a proximal side of the absorbent member, and is adhesively coated to fasten the drape layer to the absorbent member. A cover layer disposed over the drape layer defines an internal open window such that the open window is adjacent the absorbent member. A distal side of the cover layer is adhesively coated to secure the cover layer to the contact layer.
