Wound packing

摘要

The present invention relates to a wound packing material that comprises a porous material and is suitable for use in negative pressure wound therapy. The wound packing material comprises frangible regions defining a plurality of portions, the frangible regions allowing the portions to be selectively removed. The invention further relates to methods of manufacturing the wound packing material, and to methods of its use.

主权项

1. A wound packing material comprising:
a body of porous material having a first configuration and a second configuration, the body in the first configuration comprising: an X dimension spanning the entirety of the body in an plane parallel to an X plane containing the X dimension; a Y dimension spanning the entirety of the body in an plane parallel to a Y plane containing the Y dimension; and a Z dimension spanning the entirety of the body in any plane parallel to a Z plane containing the Z dimension; wherein the X, Y, and Z dimensions are each oriented orthogonal to each other and the X, Y, and Z planes are each oriented orthogonal to each other; frangible regions defining a plurality of portions of porous material, the frangible regions allowing the portions to be selectively removed from the body, wherein each of the plurality of portions defined by the frangible regions is configured to be selectively removed to change shape of the body in the X, Y, and Z dimensions from the first configuration to the second configuration wherein:
the body in the X dimension in at least one plane parallel to the X plane has at least some portion but not all portions of porous material removed;the body in the Y dimension in at least one plane parallel to the Y plane has at least some portion but not all portions of porous material removed; andthe body in the Z dimension in at least one plane parallel to the Z plane has at least some portion but not all portions of porous material removed.
