Hemostatic Composition with Magnetite

Abstract

A composition and method of arresting the flow of blood from a bleeding wound. The composition preferably includes an anhydrous salt ferrate compound preferably combined with an effective amount of an insoluble cation exchange material and an effective amount of anhydrous Magnetite mixed uniformly together. Povidone iodine may be added for enhanced antimicrobial properties. In the method, a quantity of the composition is magnetically attached to a surface of a magnet, after which the powderous mixture is applied to the wound by pressing the surface covered with the powderous compound against the wound for a time sufficient to clot the blood to arrest substantial further blood flow from the wound.

1 . A method of arresting the flow of blood from a bleeding wound comprising the steps of:
 A. providing a powderous mixture of a substantially anhydrous compound of a salt ferrate which will hydrate in the presence of blood thereby promoting clotting of the blood and an anhydrous compound of Magnetite wherein said powderous mixture is magnetic;   B. magnetically attaching a quantity of said powderous mixture directly or indirectly to a surface of a magnet;   C. applying said powderous mixture to the wound by pressing the surface covered with said powderous compound against the wound for a time sufficient to clot the blood to arrest substantial further blood flow from the wound.   
   
   
       2 . The method of  claim 1 , wherein:
 said powderous mixture also includes an insoluble cation exchange material.   
   
   
       3 . The method of  claim 2 , wherein:
 said powderous mixture includes a quantity of povidone iodine as an antimicrobial.   
   
   
       4 . A composition useful in promoting healing of a bleeding wound comprising:
 a substantially anhydrous salt ferrate compound combined with an effective amount of an insoluble cation exchange material;   an effective amount of anhydrous compound of particulate or powderous Magnetite mixed uniformly with said salt ferrate compound and said cation exchange material.   
   
   
       5 . A composition as set forth in  claim 4 , wherein:
 said cation exchange material is a resin which is crosslinked in the range of 0.25% to 15%.   
   
   
       6 . A composition as set forth in  claim 4 , wherein:
 said cation exchange material is present in a ratio of 1:7 with respect to said salt ferrate compound.   
   
   
       7 . A composition as set forth in  claim 4 , further comprising:
 an effective amount of povidone iodine as an antimicrobial.   
   
   
       8 . A hemostatic agent adapted to be applied directly onto a bleeding wound comprising:
 an effective amount of a salt ferrate combined with an effective amount of an insoluble cation exchange material and an effective amount of particulate or powderous Magnetite, said salt ferrate promoting blood clotting at the wound, said cation exchange material forming a protective cover over the wound.   
   
   
       9 . A hemostatic agent as set forth in  claim 8 , further comprising:
 an effective amount of povidone iodine as an antimicrobial.   
   
   
       10 . A hemostatic agent adapted to be applied directly onto a bleeding wound comprising:
 an effective amount of a hemostatic compound or hemostatic mixtures and an effective amount of a magnetic powder or material.
