Abstract
Disclosed is a wound dressing material comprising a substrate, about 2.5% to about 8% by weight of a bicarbonate, and a film-forming agent, the film-forming agent serving as a binder for said bicarbonate to said substrate, the film-forming agent and the bicarbonate being present in a ratio of between 1:2 and 2:1 with respect to one another. Also disclosed are a method for preparing a wound dressing material and a method for treating a wound.
Claims21
A wound dressing material comprising a substrate, greater than 2% by weight of a bicarbonate, and a film-forming agent, said film-forming agent serving as a binder for said bicarbonate to said substrate, the film-forming agent and the bicarbonate being present in a ratio of between 1:2 and 2:1 with respect to one another.
A method of making a wound dressing material, the method comprising:
- providing a substrate;
- applying an aqueous wound dressing composition to the substrate, said composition comprising a bicarbonate and a film-forming agent, the bicarbonate and the film forming agent being present in the wound dressing composition at a ratio of from 1:2 to 2:1 relative to each other;
- and
- drying the at least a part of the wound dressing material having the at least a portion of the wound dressing solution composition applied thereto to yield a wound dressing material that includes greater than 2% by weight of said bicarbonate.
A method of treating a wound, comprising applying a wound dressing material, said wound dressing material comprising a substrate, greater than 2% by weight of a bicarbonate, and a film-forming agent, said film-forming agent serving as a binder for said bicarbonate to said substrate, the film-forming agent and the bicarbonate being present in a ratio of between 1:2 and 2:1 with respect to one another.
