Abstract
Embodiments disclosed herein are directed to the treatment of wounds using negative pressure. Some embodiments disclosed herein provide for a foam pad, which may be suitable for use in abdominal wound sites, and which may be sized in a dimensionally-independent manner. Additional embodiments provide for a wound contact layer, as well as a system for the treatment of abdominal wounds.
Claims17
A porous pad for the treatment of wounds using negative pressure, wherein the pad comprises:
- a porous material suitable for channeling wound exudate from a wound site and negative pressure to the wound site;
- a generally planar shape with a thickness less than the width and length;
- and
- at least one cut extending through at least a portion of the thickness of the pad, the cut defining a pad section detachable from the pad to modify the size of the pad in a dimensionally-independent manner wherein a length and a width of the pad can be modified independently of each other, permitting a portion of the pad to be detached.
A system for the treatment of a wound site using negative pressure, the system comprising:
- a wound contact layer, wherein the wound contact layer is provided with one or more openings for channeling wound exudate and distributing negative pressure;
- a generally planar porous pad suitable for the transmission of negative pressure to a wound site and provided with a thickness less than its width and length, wherein the pad further comprises at least one cut extending through at least a portion of the thickness of the pad to define a pad section detachable from the pad to permit the pad to be sized in a dimensionally-independent manner wherein the length and the width of the pad can be modified independently of each other;
- a flexible drape configured to be placed over the porous pad;
- a source of negative pressure;
- and
- a conduit configured to transmit negative pressure from the source to the flexible drape.
A method of treating a wound site using negative pressure, wherein the treatment comprises:
- placing a wound contact layer onto the wound site;
- placing a porous pad over the wound contact layer, wherein the porous pad comprises a plurality of perforations arranged to allow removal of portions of the porous pad in a dimensionally-independent manner wherein a length and a width of the pad can be modified independently of each other, and wherein placing the porous pad comprises removing portions of the porous pad along at least one of said perforations to size the porous pad to fit within the wound site;
- sealing the wound site with a flexible drape configured to be positioned over the wound and sealed to the skin surrounding the wound;
- connecting a source of negative pressure to the wound site, wherein the source of negative pressure is connected through a conduit fluidically connected between the drape and the source of negative pressure;
- and
- maintaining the application of negative pressure to the wound site until the wound site has reached a desired level of healing.
