Abstract
A wound packing material is provided, suitable for use in negative pressure wound therapy, including a body of a porous material, the body including frangible regions defining a plurality of portions, the frangible regions allowing the portions to be selectively removed from the body. Methods of manufacturing the wound packing material, and methods of its use are also provided.
Claims17
A wound packing material comprising:
- a body of porous material, the body comprising a plurality of outer surfaces and a plurality of outer edges, each of the plurality of outer edges disposed at an interface of a pair of adjacent outer surfaces, each of the outer surfaces delimited by a subset of the plurality of outer edges, the body comprising frangible regions defining a plurality of portions, the frangible regions allowing the portions to be selectively removed from the body, wherein the wound packing material comprises a first partial pre-cut that extends in a first direction from a first outer surface of the body to a second outer surface of the body, wherein the wound packing material comprises a second partial pre-cut that extends in the first direction from the first outer surface of the body to the second outer surface of the body, wherein each of the first and second partial pre-cuts is spaced apart from each outer edge of the subset of outer edges that delimits the first outer surface, and wherein the wound packing material comprises a third partial pre-cut that extends in a second direction from a third outer surface of the body to a fourth outer surface of the body, wherein the third partial pre-cut is spaced apart from each outer edge of the subset of outer edges that delimits the third outer surface.
