US Patent 7320801 Patch for treating symptoms of a skin abscess

A patch, or bandage for treating skin infections has a backing with pressure-sensitive adhesive for securing on a user's skin in the area of the boil. A liquid absorbent member is positioned in the center of the patch, while a carrier with a medicinal formulation, comprising a menthol solution, surrounds the absorbent member. The medicinal substance is covered with one or more concentric removable covers, which are peeled off depending on the size of the boil. The menthol solution forms a barrier preventing bacteria from expanding the boil. Once the boil drains, the exudates is absorbed by the absorbent member.
