Wound dressing containing honey and collagen
A wound dressing makes use of a saccharide, such as Manuka honey, in combination with collagen in order to suppress the efficacy of matrix metalloproteinases enzymes (“MMPs”) present in chronic wounds. The mixture is applied to an absorbent surface that is designed to absorb the mixed saccharide only partially.
1. A dressing for application to a wound comprising:
a wound contacting layer comprising:
a first layer consisting of honey having a first viscosity and a supplemental material; and
a second layer comprising the honey, the supplemental material, and a powdered collagen;
wherein the honey, the supplemental material, and the powdered collagen form a mixture in the wound contacting second layer having a viscosity that is greater than the viscosity of the honey.
2. The dressing of claim 1 , wherein the supplemental material is cane sugar.
3. The dressing of claim 2 , wherein the cane sugar comprises crystalline sugar.
4. The dressing of claim 2 , wherein the cane sugar comprises powdered sugar.
5. The dressing of claim 2 , wherein the cane sugar comprises a sugar syrup.
6. The dressing of claim 1 , wherein the supplemental material has antimicrobial properties.
7. The dressing of claim 6 , wherein the supplemental material comprises silver.
8. The dressing of claim 1 , wherein the wound contact second layer comprises between 10% and 45% by weight of honey.
9. The dressing of claim 1 , wherein the wound contacting second layer comprises greater than 90% by weight of honey.
10. The dressing of claim 9 , wherein the wound contacting second layer comprises less than 10% by weight of collagen.
11. The dressing of claim 1 , wherein the wound contacting second layer comprises between 40% and 80% by weight of the supplemental material.
12. The dressing of claim 1 , wherein the wound contacting second layer comprises between 10% and 50% by weight of collagen.
13. A dressing for application to a wound comprising:
a wound contacting layer comprising honey having a first viscosity and powdered collagen;
a film layer;
an absorbent layer; and
a cover layer;
wherein the wound contacting layer is applied to the film layer, and
wherein the honey and powdered collagen form a mixture in the wound contacting layer having a viscosity that is greater than the viscosity of the honey.
14. The dressing of claim 13 , wherein the wound contacting layer comprises:
a first layer adjacent to the wound surface, the first layer comprising honey and cane sugar; and
a second layer comprising honey, cane sugar and powdered collagen.
15. The dressing of claim 14 , wherein the first layer of the wound contacting layer consists essentially of honey and cane sugar.
16. The dressing of claim 13 , wherein the wound contacting layer comprises:
a first layer adjacent to the wound surface, the first layer comprising honey and a supplemental material; and
a second layer comprising honey, the supplemental material and powdered collagen.
17. The dressing of claim 13 , wherein the wound contacting layer comprises:
a first layer adjacent to the wound surface, the first layer comprising honey and powdered collagen; and
a second layer comprising honey, a supplemental material and powdered collagen.
