摘要:
The subject invention concerns methods for preparing alkaline earth ferrates and the preparation of hemostatic compositions from alkaline earth ferrates. In one embodiment, the alkaline earth ferrate is strontium ferrate. In one embodiment, methods of the invention comprise heat treating mixtures of alkaline earth oxides and/or peroxides with iron oxides, such as hematite or magnetite. The subject invention also concerns hemostatic compositions produced using metallic oxides that are reacted with alkaline earth oxides and/or peroxides and the methods used to produce the hemostatic compositions.
摘要:
The subject invention pertains to methods and compositions for wound treatment. The methods and compositions provide for promoting and accelerating wound healing; provide for inhibition of microbial infection; provide for a protective scab-like covering on a wound; and/or for arresting the flow of blood or body fluids from an open wound. The methods and compositions can be used to increase granulation and epithelialization in a wound. In one embodiment, a substantially anhydrous compound of a salt ferrate and a cation exchange material is provided. Compositions of the invention can also include silver compounds. In use, compositions of the invention are preferably applied as a dry dressing to an exuding chronic wound site. If the chronic wound site is dry, the wound site may be wetted with a suitable liquid or aqueous media prior to applying the dressing in dry form.

The subject invention pertains to materials and methods for stopping or decreasing the blood flow from an open wound or medical or surgical procedure. Compositions of the invention comprise a salt form of a cross-linked polyacrylic acid. In one embodiment, the composition comprises a sodium salt of a polyacrylic acid. Compositions of the invention can also optionally comprise one or more different salt ferrates, and/or a cationic exchanger resins, and/or a silver compound. In an exemplified embodiment, a composition of the invention comprises sodium polyacrylate provided in a dry powdered form. Polyacrylate compositions of the invention can be applied directly to a wound or treatment site, or they can be incorporated into a wound dressing, such as a bandage. The clot or scab formed at a wound or treatment site treated with the present invention is extremely elastic and exhibits considerable tensile strength when stretched to the breaking point. The subject invention also concerns wound and surgical site dressings and coverings, and methods of using a composition of the invention to stop blood flow from an open wound or treatment site.
