PROPHYLACTIC DRESSING AND USE OF SAME IN THE PREVENTION OF INFECTION
Wounds and temporary appliances can be protected against liquid contamination using a prophylactic dressing. The dressing includes a liquid resistant sheet and disposed thereon a first liquid barrier/adhesive strip and a second liquid barrier/adhesive strip wherein the first and second liquid barrier/adhesive strips are concentric; located at or near the periphery of the liquid resistant sheet; and are separated from one another by a gap. Adsorbent's and liquid indicators can be employed within the gap to add further functionality to the dressing. Also disclosed herein is a support useful for stabilizing leads to transcutaneous or percutaneous devices.
1 . A dressing comprising a liquid resistant sheet and disposed thereon a first liquid barrier/adhesive strip and a second liquid barrier/adhesive strip wherein the first and second liquid barrier/adhesive strips are concentric; located at or near the periphery of the liquid resistant sheet; and are separated from one another by a gap.
2 . The dressing of claim 1 wherein the liquid resistant sheet is completely impermeable.
3 . The dressing of claim 1 wherein the liquid resistant sheet is able to pass vapor while precluding the passage of liquids.
4 . The dressing of claim 1 wherein the liquid resistant sheet is of one or more layers.
5 . The dressing of claim 1 wherein the liquid resistant sheet is prepared using a polymer.
6 . The dressing of claim 1 wherein the first liquid barrier/adhesive strip is selected from the group consisting of Allevyn™, and Elasto-Gel™.
7 . The dressing of claim 1 wherein the first liquid barrier/adhesive strip and the second liquid barrier/adhesive strip are prepared using the same adhesive.
8 . The dressing of claim 1 wherein the gap is filled with an adsorbent material.
9 . The dressing of claim 1 wherein the gap is filled with a liquid indicator.
10 . The dressing of claim 1 wherein the gap is filled with an absorbent also including a liquid indicator.
11 . The dressing of claim 1 wherein the liquid indicator is a dye selected from the group consisting of: triarylmethane dye, a monoazo dye, a diazo dye, a xanthene dye, an anthraquinone dye, an indigoid dye, a quinoline dye, an FD&C dye, and a D&C dye.
12 . The dressing of claim 1 further comprising a bottom piece.
13 . The dressing of claim 12 wherein the bottom piece comprises an adhesive sheet and affixed upon the side opposite the adhesive, a foam pad wherein the foam pad is configured to support the leads from a transcutaneous or percutaneous device.
14 . The dressing of claim 13 wherein the dressing further comprises a strap which, when folded over a lead or leads secures the leans in place on the foam pad.
15 . The dressing of claim 1 wherein at least a part of the dressing that will be in contact with a wound is treated with a composition to mitigate or stop the would from sticking to the dressing.
16 . A method of protecting open wounds and transcutaneous or percutaneous devices from contamination comprising placing a dressing comprising a liquid resistant sheet and disposed thereon a first liquid barrier/adhesive strip and a second liquid barrier/adhesive strip wherein the first and second liquid barrier/adhesive strips are concentric; located at or near the periphery of the liquid resistant sheet; and are separated from one another by a gap; over the wound or point of insertion of the transcutaneous or percutaneous device.
17 . A method of protecting open wounds and transcutaneous or percutaneous devices from contamination comprising:
placing a dressing comprising a liquid resistant sheet and disposed thereon a first liquid barrier/adhesive strip and a second liquid barrier/adhesive strip wherein the first and second liquid barrier/adhesive strips are concentric; located at or near the periphery of the liquid resistant sheet; and are separated from one another by a gap; and disposed within the gap is a liquid indicator; over the wound or point of insertion of the transcutaneous or percutaneous device; and
then periodically observing the liquid indicator to determine whether the first liquid barrier has been breached.
18 . The method of claim 17 wherein the liquid indicator is a dye selected from the group consisting of: triarylmethane dye, a monoazo dye, a diazo dye, a xanthene dye, an anthraquinone dye, an indigoid dye, a quinoline dye, an FD&C dye, and a D&C dye.
19 . A device comprising an adhesive sheet and affixed upon the side opposite the adhesive, a foam pad wherein the foam pad is configured to support the leads from a transcutaneous or percutaneous appliance.
20 . A method of reducing the pain from the use of a transcutaneous or percutaneous appliance comprising employing the device of claim 19 on a patient to stabilize the lead of the appliance.
