Abstract
A method for preparing a composition for external treatment of wounds includes charging at least 90% of the oxygen binding sites of hemoglobin with carbon monoxide during or after isolation from its natural environment. The method further includes adding at least one further ingredient selected from the group consisting of electrolyte(s), preservative(s), stabilizer(s), anti-flocculant(s), anticoagulant(s), pH buffering agent(s), solvent(s), antioxidant(s), film-forming agent(s) and crosslinking agent(s). The method can further include packaging the composition, such as in an aerosol can.
Claims5
A method for external treatment of an open wound surface comprising:
- preparing an aqueous solution by charging an oxygen carrier with carbon monoxide during or after isolation from its natural environment, wherein the oxygen carrier comprises hemoglobin, wherein at least 90% of oxygen binding sites of the oxygen carrier are charged by carbon monoxide;
- adding at least one further ingredient selected from the group consisting of electrolyte(s), preservative(s), stabilizer(s), anti-flocculant(s), anticoagulant(s), pH buffering agent(s), solvent(s), antioxidant(s), film-forming agent(s) and crosslinking agent(s) to the aqueous solution;
- packaging the aqueous solution in an aerosol can;
- and
- applying the aqueous solution to the open wound surface without oxygen preloading.
