Manual debriding pad
An example debriding pad includes a support layer, a first region, and a second region. The first region includes a first material defining a plurality of first loop piles arranged on the support material. The second region includes a second material defining a plurality of second loop piles arranged on the support material. The second material is stiffer than the first material to provide more aggressive debridement of a wound.
1 . A debriding pad, comprising:
a support layer comprising 500 denier multifilament polyester warp yarns, 840 denier multifilament polyester warp yarns, and 2000 denier multifilament polyester weft yarns;
a first region comprising a first material defining a plurality of first loop piles arranged on the support layer; and
a second region comprising a second material defining a plurality of second loop piles arranged on the support layer, wherein the second material is stiffer than the first material, and wherein the first region is disposed on a first side of the debriding pad and the second region is disposed on a second side of the debriding pad opposite the first side.
2 . The debriding pad of claim 1 , wherein the second region further comprises the first material defining a plurality of third loop piles arranged on the support layer.
3 . The debriding pad of claim 1 , wherein the support layer comprises a scrim, wherein the plurality of first loop piles and the plurality of second loop piles are inserted into the scrim.
4 . The debriding pad of claim 1 , wherein a linear mass density of the first material is within a range from about 100 denier to about 300 denier.
5 . The debriding pad of claim 4 , wherein the second material comprises polyester yarn with a linear mass density within a range from about 1200 denier to about 1800 denier.
6 . The debriding pad of claim 1 , wherein the first material comprises textured polyester yarn.
7 . The debriding pad of claim 6 , wherein the textured polyester yarn comprises a blend of polyester fibers and natural fibers, the natural fibers comprising at least one of: cotton, or rayon.
8 . The debriding pad of claim 1 , wherein a linear mass density of the second material is within a range from about 1000 denier to about 2000 denier.
9 . The debriding pad of claim 8 , wherein the second material comprises monofilament yarn.
10 . The debriding pad of claim 1 , wherein each loop pile of the plurality of first loop piles comprises about 4 ends of yarn per loop pile.
11 . The debriding pad of claim 1 , wherein courses per inch of the plurality of second loop piles is within a range from about 15 courses per inch to about 20 courses per inch.
12 . The debriding pad of claim 1 , wherein an average loop height relative to the support layer of the plurality of first loop piles is within a range from about 5 millimeters (mm) to about 10 mm.
13 . The debriding pad of claim 1 , wherein an average loop height relative to the support layer of the plurality of second loop piles is within a range from about 5 mm to about 10 mm.
14 . The debriding pad of claim 1 , wherein a density of the plurality of first loop piles is within a range from about 50 stiches per inch to about 400 stiches per inch.
15 . The debriding pad of claim 1 , wherein a density of the plurality of second loop piles is within a range from about 50 stiches per inch to about 400 stiches per inch.
16 . The debriding pad of claim 1 , wherein the debriding pad further comprises at least one of: an absorbent material adjacent to the support layer, or a moisture resistant layer adjacent to the support layer.
17 . The debriding pad of claim 1 , wherein the debriding pad defines a pocket configured to receive at least a portion of a hand or a distal end of an elongate tool.
18 . The debriding pad of claim 1 , wherein at least one of the first region or the second region comprises an antimicrobial agent disposed on or within the respective region.
19 . A method comprising:
forming, on a support layer, a plurality of first loop piles comprising a first material to define a first region, the support layer comprising 500 denier multifilament polyester warp yarns, 840 denier multifilament polyester warp yarns, and 2000 denier multifilament polyester weft yarns;
forming, on the support layer, a plurality of second loop piles comprising a second material to define a second region, wherein the second material is stiffer than the first material; and
securing at least one first free edge of the support layer to at least one second free edge of the support layer to form a debriding pad, wherein the first region is disposed on a first side of the debriding pad and the second region is disposed on a second side of the debriding pad opposite the first side.
20 . The method of claim 19 , wherein at least one of forming the plurality of first loop piles or forming the plurality of second loop piles comprises knitting at least one of the first material or the second material to the support layer.
