Embodiment approach
[0113] The wound dressing of the invention comprises a matrix of polymeric foam with polysaccharide coated conduits within the foam. Prior to deployment of the wound dressing on the wound surface, the conduit wall defines unoccupied or partially occupied compartments or channels within the stroma. During use, the polysaccharide becomes hydrated by absorbing wound exudate and thereby forms a gel which swells. Swelling polysaccharide almost completely and / or partially occupies previously unoccupied compartments or channels, but retains sufficient openness for gas and liquid between the two opposing outer surfaces of the foam, i.e. not in direct contact with the wound transmission between the outer surface of the bed and exposed to the external environment and the opposite outer surface in direct contact with the wound bed. The aforementioned opposing outer surfaces are also referred to herein as the "outward" and "inward" surfaces of the foam, respectively, with reference to th...
Embodiment 1
[0194] Common Example 1 .Management of a clean, viable dermal wound bed
[0195] The serous fluid secreted at the wound surface travels along the duct wall, is absorbed by the hyaluronic acid contained therein, and fully or partially hydrates the hyaluronic acid (as in figure 2 described in ), depending on the amount of fluid (moisture) at the wound surface. The wetting hyaluronic acid prevents drying of the healing wound, which enhances the epithelialization of the healing wound directed through the dressing surface. Complexation of hyaluronic acid with fibrin in the secreted fluid allows the dressing to adhere to the wound, forming an "artificial, reinforced scab" that prevents the proliferation of any foci of infection. when carried out as in image 3 When the epithelium is formed (usually over the dermal remnant) as described in , the keratinized epidermal layer separates the wound dressing from the wound. The detached wound dressing area can be cut away with scissors....
Embodiment 2
[0196] Common Example 2 .Management of wound beds with locally persistent eschar or light pollution
[0197] As described in General Example 1, the serous fluid secreted at the wound surface travels along the duct wall, is absorbed by hyaluronic acid, and hyaluronic acid is fully or partially hydrated (as in figure 2 described in ), depending on the amount of fluid (moisture) at the wound surface. The wetting hyaluronic acid prevents drying of the healing wound, which enhances the epithelialization of the healing wound directed through the dressing surface. The moist environment, along with the normal inflammatory response, promotes maceration ("autolysis") of eschar remnants and regression of contaminated foci. The autolysate absorbed by the hyaluronic acid along with the fibrin in the secreted fluid allows the dressing to adhere to the wound, forming an "artificial, reinforced scab" that prevents the proliferation of any foci of infection. As in common embodiment 1, car...
