Abstract
A wound dressing composition having a first layer of a lyophilized hydrogel layer having hydrolyzed collagen and hydrolyzed hyaluronic acid ingredients, wherein the first layer has a water content of 10 percent or less and is configured to lay onto a wound. The first layer can be cut or molded to various shapes such as a rectangle, a square, a polygon, an oval or a circle. The first layer is hermetically sealed in a cover or barrier and placed in final packaging. Alternatively, one or more additional layers are stacked onto the first layer, each additional one or more layers having a water content greater than that of the first layer.
Claims9
A multiple layer wound dressing composition comprising:
- a first layer of a lyophilized hydrogel layer having hydrolyzed collagen and hydrolyzed hyaluronic acid ingredients, the first layer having a water content of 10 percent or less and configured to lay onto a wound surface;
- one or more additional layers of lyophilized hydrogel stacked onto the first layer, each additional one or more layers having a water content greater than that of the first layer;
- and
- removable interleaved barrier sheets between the layers to prevent degradation of the water content of each layer.
A method of applying a multiple layer wound dressing composition comprising the steps of:
- providing a first layer of a lyophilized hydrogel layer having hydrolyzed collagen and hydrolyzed hyaluronic acid ingredients with a water content of 10 percent or less;
- providing one or more additional layers of lyophilized hydrogel stacked onto the first layer with removable interleaved barrier sheets between the layers to prevent degradation of the water content of each layer, each additional one or more layers having a water content greater than that of the first layer;
- removing the interleaved barrier sheets at a tear seam along one of two sides or ends of the interleaved barrier sheets;
- and
- pulling the interleaved barrier sheets apart and away from the layers allowing the layers to lie on top of one another over a wound surface.
