Dressing having integral antimicrobial
View Patent ↗A dressing having integral antimicrobial includes a transparent film layer having a top side, an opposite bottom side, and an insertion site viewing portion. The dressing also includes an antimicrobial member having a top side and an opposite bottom side. The antimicrobial member top side is adhered to the film layer bottom side in the insertion site viewing portion. The antimicrobial member includes at least one pair of elongated, spacedly disposed portions defining a slot therebetween. A zone of inhibition defined by the antimicrobial member covers an entire area of the slot between the member portions.
1. A dressing comprising:
a transparent film layer having a top side, an opposite bottom side, and an insertion site viewing portion, the transparent film layer defining an outermost layer of the dressing;
an antimicrobial member having a top side and an opposite bottom side, said antimicrobial member top side being adhered to said transparent film layer bottom side in said insertion site viewing portion;
said antimicrobial member including at least one pair of elongated, spacedly disposed portions defining a slot therebetween, the slot having a width sized to accept a catheter lumen;
wherein a zone of inhibition defined by said antimicrobial member entirely covers the slot; and
wherein the transparent film layer bottom side includes an adhesive portion and an adhesive-free portion, the adhesive portion being disposed within the insertion site viewing portion so as to adhere the antimicrobial member to the film layer, and wherein the adhesive-free portion is disposed in the slot between the antimicrobial member portions.
2. The dressing of claim 1 , wherein said antimicrobial member bottom side includes an adhesive thereon.
3. The dressing of claim 2 , wherein said antimicrobial member bottom side includes an adhesive free portion adjacent said slot.
4. The dressing of claim 2 , wherein said adhesive on said antimicrobial member bottom side includes at least one of an antimicrobial agent, an antifungal agent, an antiseptic agent, an antibacteriocidal agent, and an antiviral agent.
5. The dressing of claim 1 , wherein each said spacedly disposed portion includes a curved sidewall adjacent said slot.
6. The dressing of claim 5 , wherein each said spacedly disposed portion includes a blade extending from said curved sidewall towards the other of said spacedly disposed portions.
7. The dressing of claim 1 , wherein the pair of elongated, spacedly disposed portions include a first portion and a second portion, wherein the first and second portions cooperate to define the zone of inhibition such that the first portion has a first zone of inhibition reach that extends at least to a center of the slot and wherein the second portion has a second zone of inhibition reach that extends to the center of the slot.
8. The dressing of claim 7 , wherein the first and second zone of inhibition reaches overlap.
9. The dressing of claim 1 , wherein said antimicrobial member bottom side has no adhesive thereon.
10. The dressing of claim 1 , wherein said slot has a width approximately in a range of 0.05 inches to 0.4 inches.
11. The dressing of claim 1 , wherein said antimicrobial member includes at least one of an antimicrobial agent, an antifungal agent, an antiseptic agent, an antibacteriocidal agent, and an antiviral agent.
12. The dressing of claim 1 , wherein said antimicrobial member is made of a carrier material impregnated with at least one of an antimicrobial agent, an antifungal agent, an antiseptic agent, an antibacteriocidal agent, and an antiviral agent, and including a slow release binder.
13. The dressing of claim 1 , wherein said pair of spacedly disposed portions are generally parallel.
14. The dressing of claim 1 , wherein said pair of spacedly disposed portions are disconnected.
15. The dressing of claim 1 , wherein said antimicrobial member is bifurcated such that said spacedly disposed portions define prongs of the bifurcated antimicrobial member.
16. The dressing of claim 1 , wherein said antimicrobial member includes at least one tie connecting said spacedly disposed portions, said tie having a height that is less than a height of each of said spacedly disposed portions.
17. The dressing of claim 1 , wherein each said pair of spacedly disposed portion includes a sloped sidewall such that said slot is tapered towards said antimicrobial member bottom side.
18. The dressing of claim 1 , wherein each said spacedly disposed portion includes a sidewall adjacent said slot, said sidewall having a scalloped surface facing said slot.
19. The dressing of claim 1 , wherein said antimicrobial member includes a carrier layer and an adjacent fibrous layer.
