Wound dressing with advanced fluid handling

摘要

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.

1. A wound dressing, which comprises:
a porous contact layer for positioning adjacent a wound, wherein material of the porous contact layer is porous for permitting transmission of wound fluids and moisture vapor there through, the porous contact layer defining a distal wound-facing surface and an opposed proximal surface, the porous contact layer defining a distal window extending there through; an absorbent member disposed in superimposed relation to the distal window of the porous contact layer, the absorbent member dimensioned to extend laterally beyond the distal window such that a portion of the absorbent member overlaps and is secured to the proximal surface of the porous contact layer; a drape layer disposed on a proximal side of the absorbent member, a distal side of the drape layer adhesively coated to fasten the drape layer to the absorbent member; and a cover layer defining a proximal window, the cover layer disposed over the drape layer such that the proximal window is adjacent the absorbent member, a distal side of the cover layer adhesively coated to secure the cover layer to the porous contact layer.
