Abstract

A method of arresting the flow of blood and other protein containing body fluids flowing from an open wound and for promoting wound healing. In the method, a substantially anhydrous compound of a salt ferrate is provided for a unique use which, when hydrated after mixing with a victim'"'"'s own blood or other aqueous media, produces Fe⁺⁺⁺ thereby promoting clotting when applied in a paste form to the wound for a time sufficient to arrest substantial further blood and other body fluid flow from the wound. The compound is formed of a ferrate (VI) salt taken from the group consisting of H, Li, Na, K, Rb, Cs and Fr. However, to decrease or eliminate stinging sensation, the compound may be formed having a ferrate (VI) salt taken from the group consisting of Be, Mg, Ca, Sr, Ba, Ra, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, Ge, Zr, Nb, Mo, Tc, Ru, Rh, Pd, Ag, Cd, In, Sn, Hf, Ta, W, Re, Os, Ir, Pt, Au, Hg, TI, Pb, Bi, Al, As, NH₄ and N(C₄H₉)₄. The preferred composition also includes a cation exchange material such as sulfonated ion exchange resin as an admixture which, when combined with the ferrate (VI) salt, will hydrate in the presence of blood or other aqueous media to produce Fe⁺⁺⁺, thereby promoting clotting of the blood and body fluid and to produce oxygen. The cation exchange material produces a scab or protective coating over the wound for protection and enhanced healing. Oxygen produced during the reaction substantially reduces the level of bacteria, virus and fungus at the wound. The compound must be stored dry unmixed together and mixed into a paste with the victim'"'"'s blood or other aqueous media just prior to its application to the wound.

A. mixing a substantially anhydrous compound of a salt ferrate (VI) which hydrates in the presence of blood or an aqueous media to produce Fe⁺⁺⁺ with blood flowing from a wound of a victim or an aqueous media to form a paste;

B. applying said paste to the wound within a short time period of about five minutes after step A for a time sufficient to effect sufficient clotting of the blood to arrest substantial further blood flow from the wound.
