Abstract

Claims (26)

1 . A dressing for treating a wound on a digit, comprising:

a digit contact layer configured to substantially prevent adherence of the dressing to the wound, wherein a portion of the digit contact layer defines an enclosure on a non-wound-facing side of the digit contact layer, the enclosure being defined independently from any contact between the digit contact layer and the digit;

an absorbent enclosed within the enclosure and configured to absorb fluid from the wound through the digit contact layer;

an antimicrobial layer coupled to a wound-facing side of the digit contact layer, the antimicrobial layer comprising an antimicrobial substance;

a first roll coupled to the enclosure on the non-wound-facing side of the digit contact layer and unrollable to cover the digit, the digit contact layer, the enclosure, and the antimicrobial layer; and

a second roll coupled to the first roll and unrollable to cover the first roll, the digit, the digit contact layer, the enclosure, and the antimicrobial layer.

2 . The dressing of claim 1 , comprising a film barrier positioned between the antimicrobial layer and the wound-facing side of the digit contact layer, the film barrier configured to substantially prevent the flow of the antimicrobial substance therethrough from the antimicrobial layer to the digit contact layer.

3 . The dressing of claim 1 , wherein the second roll comprises a fluid-resistant material configured to substantially prevent at least one of ingress of fluid to the dressing or egress of fluid from the dressing.

4 . The dressing of claim 1 , wherein the absorbent comprises an absorbent layer positioned between the non-wound-facing side of the digit contact layer and the first roll.

5 . The dressing of claim 4 , wherein the second roll comprises a fluid-resistant material configured to substantially prevent ingress of fluid to the dressing.

6 . The dressing of claim 1 , wherein the first roll comprises absorbent fibers.

7 . The dressing of claim 6 , wherein the second roll comprises a fluid-resistant material configured to substantially prevent ingress of fluid to the dressing.

8 . The dressing of claim 1 , wherein at least one of the first roll or the second roll is configured to provide a compressive force that holds the dressing on the digit.

9 . The dressing of claim 1 , wherein the antimicrobial substance comprises povidone-iodine and wherein the antimicrobial layer comprises gelatin.

10 . A dressing for treating a wound on a digit, comprising:

a digit contact layer configured to substantially prevent adherence of the dressing to the wound, wherein a portion of the digit contact layer defines an enclosure on a non-wound-facing side of the digit contact layer, the enclosure being defined independently from any contact between the digit contact layer and the digit;

an absorbent layer coupled to the non-wound-facing side of the digit contact layer and enclosed within the enclosure;

a first roll coupled to the enclosure and unrollable to cover the digit, the digit contact layer, the enclosure, and the absorbent layer; and

a second roll coupled to the first roll and unrollable to cover the first roll, the digit, the digit contact layer, the enclosure, and the absorbent layer;

wherein the second roll comprises a fluid-resistant material configured to substantially prevent the ingress of fluid into the dressing.

11 . The dressing of claim 10 , wherein the digit contact layer comprises an antimicrobial substance.

12 . The dressing of claim 11 , wherein the antimicrobial substance comprises povidone-iodine.

13 . The dressing of claim 10 , comprising an antimicrobial layer coupled to a wound-facing side of the digit contact layer.

14 . The dressing of claim 13 , comprising a film barrier positioned between the antimicrobial layer and the digit contact layer;

wherein the film barrier is configured to substantially prevent an antimicrobial agent from flowing therethrough from the antimicrobial layer to the absorbent layer.

15 . The dressing of claim 10 , wherein the first roll and the second roll form a tube of elasticated cotton, and wherein the second roll is coated or laminated with a hydrophobic material.
