Disclosed is a wound dressing comprising: a backing layer; a wound contact layer having a first surface for directly contacting a wound bed and a second surface facing the backing layer; and, a perforated wound-site adhesive layer for adhering the wound dressing to a wound site and comprising a plurality of perforations, wherein the adhesive layer comprises a border region which surrounds the wound contact layer and wherein the perforations have a diameter between 1.6 mm and 2.7 mm.
Claims27
A wound dressing comprising:
- a backing layer;
- a wound contact layer having a first surface for directly contacting a wound bed and a second surface facing the backing layer;
- and,
- a perforated wound-site adhesive layer for adhering the wound dressing to a wound site and comprising a plurality of perforations,
- wherein the adhesive layer comprises a border region which surrounds the wound contact layer and wherein the perforations have a diameter between 1.6 mm and 2.7 mm.
The wound dressing of any preceding claim, wherein the adhesive layer extends continuously across the first surface of the wound contact layer.
The wound dressing of any preceding claim, wherein the perforations are uniformly distributed across the full extent of the adhesive layer.
The wound dressing of any preceding claim, wherein the perforations have a common size.
The wound dressing of any preceding claim, wherein the perforations have a common shape.
The wound dressing of any preceding claim, wherein the perforations are arranged in a regular array comprising rows and columns.
The wound dressing of any preceding claim, wherein the adhesive is silicone.
The wound dressing of any preceding claim, wherein the adhesive layer comprises an inner edge defining a central window through which the wound contact layer is exposed
- wherein the wound contact layer comprises an outer edge and overlaps the adhesive layer around the periphery of the wound contact layer so as to be adhered thereto, and,
- wherein the width of the overlap between the inner edge of the adhesive layer and the outer edge of the wound contact layer varies around the periphery of the wound contact layer.
The wound dressing of any preceding claim, wherein the backing layer is adhered to the adhesive layer.
