Wound dressing material
View Patent ↗A material for use as a wound dressing, the material being in the form of a roll and comprising gel forming fibers and the material having lines of longitudinal stitching.
1. A material for use in a wound dressing, the material being in the form of a roll and consisting essentially of gel forming fibers and optionally elastic fibers, the gel forming fibers being in the form of a non-woven mat, and the material having lines of longitudinal stitching made in nylon or polyolefin yarn, and wherein the lines of stitching restrict the contraction of the dressing on absorption of exudates and increase the strength of the wound dressing.
2. The material as claimed in claim 1 wherein the lines of stitching are from about 1 mm to about 10 mm apart and are parallel to a long edge of the material.
3. The material as claimed in claim 1 wherein the gel forming fibers are selected from the group consisting of spun cellulose fibers, chemically modified cellulosic fibers, pectin fibers, alginate fibers, chitosan fibers, hyaluronic acid fibers, other polysaccharide fibers, fibers derived from gums and mixture thereof.
4. The material as claimed in claim 1 wherein the material comprises more than one layer and a wound contacting layer comprises gel forming fibers.
5. The material as claimed in claim 1 wherein the stitching is through the whole thickness of the material.
