Abstract
A biocompatible material the method of making the same. The material comprises constituent fibres, yarns or filaments forming a woven, non-woven, gauze, film or knitted material incorporating an antimicrobial agent. The present material finds particular application as a wound dressing for the controlled and sustained release of a complexed form of iodine such as povidone-iodine or Cadexomer-iodine.
Claims (25)
1. A biocompatible material formed by a method of: providing a powdered iodine-complex; providing a fibre, yarn, filament or multifilament-based substrate having an open structure containing voids or interstitial regions; and introducing the powdered iodine-complex to the substrate to incorporate the iodine-complex within the structure of the substrate.
2. The material as claimed in claim 1 wherein the powdered iodine-complex comprises an iodophor, povidone-iodine, a starch-iodine-complex, a modified starch iodine-complex or the reaction product of dextrin, epichlorohydrin and iodine.
3. The material as claimed in claims 1 or 2 wherein the substrate is woven, non- woven, a gauze, a film or knitted.
4. The material as claimed in any preceding claim wherein the substrate comprises a water-absorbing swellable polymer.
5. The material as claimed in claim 4 wherein the material comprises any one or a combination of: â ¢ a polysaccharide â ¢ a polysaccharide-based material â ¢ a hydrocolloid forming compound â ¢ an alginate â ¢ chitosan â ¢ chitin â ¢ pectin â ¢ carboxymethyl cellulose â ¢ hydroxypropyl methylcellulose â ¢ gellan â ¢ konjac; â ¢ psyllium.
6. The material as claimed in any one of claims 1 to 3 wherein the substrate comprises a polyester, a polyamide, a cellulosic, an acrylic or a biopolymer.
7. The material as claimed in any preceding claim further comprising a membrane provided over at least one external surface of the substrate, the membrane having an open structure to allow the iodine to be released from the material.
8. The material as claimed in claim 7 wherein the membrane is a gauze or mesh.
9. The material as claimed in claim 7 or 8 wherein the membrane encapsulates the substrate.
10. The material as claimed in any preceding claim wherein the substrate is a singular piece or comprises a layered structure.
11. The material as claimed in any preceding claim wherein the iodine-complex is adsorbed at a surface of the fibres, yarns, filaments or multifilaments of the substrate.
12. The material as claimed in any preceding claim further comprising a water- soluble control compound configured to control a release of the iodine from the material.
13. The material as claimed in claim 12 wherein the water-soluble control compound comprises a polyether, an alkyl ether, a glycol, a polyol or a compound having a C-O-C linkage.
14. The material as claimed in claim 12 wherein the water-soluble control compound comprises propylene glycol and/or polyethylene glycol.
15. The material as claimed in any preceding claim further comprising a polar organic compound comprising any one or a combination of an aldehyde, a ketone, an alcohol, an acetal or a compound with a hydroxyl group or a carbonyl group or acetone and/or isopropanol.
16. A biocompatible material comprising: a fibre, yam or filament-based substrate having an open structure containing voids or interstitial regions; and an iodine-complex releasably retained at the substrate and/or within the voids or interstitial regions.
17. The material as claimed in claim 16 wherein the iodine-complex is adsorbed at a surface of the fibres, yams, filaments or multifilaments of the substrate.
18. A method of forming a biocompatible antimicrobial material comprising: providing a powdered iodine-complex; providing a fibre, yarn, filament or multifilament-based substrate having an open structure containing voids or interstitial regions; and introducing the powdered iodine-complex to the substrate and allowing the powdered iodine-complex to be releasably retained at the substrate and/or within the voids or interstitial regions.
19. The method as claimed in claim 18 wherein the step of introducing the powered iodine-complex to the substrate comprises sonically agitating the substrate to facilitate entry of the iodine-complex into the voids.
20. The method as claimed in claims 18 or 19 further comprising prior to or after the step of introducing the iodine-complex to the substrate, applying an aqueous-based liquid to the substrate in which the iodine-complex is at least partially soluble.
21. The method as claimed in claim 20 wherein the aqueous liquid comprises any one or a combination of: water; a polar organic solvent; a water-soluble control compound configured to control a release of the iodine from the material.
22. The method as claimed in claim 21 wherein the aqueous liquid comprises an aldehyde, a ketone, an alcohol, an acetal or a compound with a hydroxyl group or a carbonyl group, acetone and/or isopropanol.
23. The method as claimed in claims 21 or 22 wherein the water-soluble control compound comprises any one or a combination of a polyether, an alkyl ether, a glycol, a polyol or a compound having a C-O-C linkage, propylene glycol and/or polyethylene glycol.
24. A wound dressing comprising the material as claimed in any one of claims 1 to 17.
25. The material as claimed in any one of claims 1 to 17 being any one of the following: â ¢ a nasal packing material; or â ¢ a dental packing material.
