Gap-patterned foam dressing and method of making same

A method for preparing and using a patterned foam dressing, comprising the steps of:

• providing a sheet of absorbent foam;
• applying to one side of said sheet of absorbent foam a pattern of a plurality of honey dosed foam areas;
• wherein the applied pattern of said plurality of honey dosed foam areas form a plurality of absorbent, non-honey dosed areas on the one side of said sheet of absorbent foam;
• and
• applying the one side of said sheet of absorbent foam to a wound treatment zone to allow the non-honey dosed absorbent areas to expand by absorbing wound exudates from the wound treatment zone which thereby causes a physical pressure to be applied to adjacent individual ones of said plurality of honey dosed foam areas which thereby causes honey disposed therein to be discharged into the wound treatment zone.

A gap-patterned wound dressing, comprising:

• a patterned, absorbent foam structure having a gap-patterned side and a non-gap patterned side, wherein the gap-patterned side includes a pattern of absorbent foam, non-honey dosed gaps disposed between absorbent foam areas dose with honey;
• wherein, when the gap-patterned wound dressing is applied to a wound treatment zone, said absorbent foam, non-honey dosed gaps expand thereby applying a physical pressure to adjacent individual ones, of said plurality of absorbent foam areas dosed with honey thereby causing honey disposed therein to be discharged into the wound treatment zone;
• and
• wherein the patterned, absorbent foam structure includes a thickness that is sufficient to hold a specific amount of honey about 50% by total weight to about 75% by total weight of the patterned, absorbent foam structure and honey, in combination.

A wound dressing, comprising:

• an absorbent foam, having a wound contact side and a non-wound contact side, wherein said wound contact side is provided with an applied pattern of a plurality of honey dosed foam areas to form a plurality of absorbent, non-honey dosed areas;
• wherein, when the applied pattern of said plurality of honey dosed foam areas and said plurality of absorbent non-honey dosed areas of the wound dressing are applied to a wound treatment zone, said absorbent, non-honey dosed areas expand thereby applying a physical pressure to adjacent individual ones of said plurality of honey dosed foam areas thereby causing honey disposed therein to be discharged into the wound treatment zone;
• wherein the wound contact side is dosed with an amount of honey that ranges from about 50% by total weight of honey to about 75% by total weight of honey to the total weight of the absorbent foam and honey, in combination;
• and
• wherein the non-wound contact side is provided with a breathable polyurethane barrier.

A honey dosed foam wound dressing comprising:

• a composite fiber reinforced, absorbent, foam structure and a non-patterned side;
• wherein the patterned side is provided with an applied pattern of a plurality of honey dosed foam areas;
• wherein the applied pattern of said plurality of honey dosed foam areas form a plurality of non-honey dosed, absorbent areas in the patterned side of said absorbent foam;
• wherein, when the wound dressing is applied to a wound treatment zone, said non-honey dosed, absorbent areas expand thereby applying a physical pressure to adjacent individual ones of said plurality of honey dosed foam areas thereby causing honey disposed therein to be discharged into the wound treatment zone;
• and
• wherein the honey dosed foam areas are dosed with, an amount of honey that is less than about 50% by weight of the total weight of wound dressing.
