  • Patent number: 11554137
    Abstract: A composition and method useful in promoting healing of a bleeding wound site. The composition preferably includes a substantially anhydrous acid form of a cation exchange resin, which when applied over blood, provides an antimicrobial against planktonic microorganisms and biofilms in the wound. The resin is also capable, when applied in sufficient quantities, of providing a continuing and persistent antimicrobial against planktonic microorganisms and biofilms through dehydration and ion exchange with cations present in the blood and other body fluids. When the resin has a concentration of at least 26 mg/ml, it provides a >3 log reduction in biological activity of MRSA, MRSE and Pseudomonas aeruginosa.

  • Patent number: 9877728
    Abstract: A hemostatic tablet preferably including potassium ferrate and a cation ion exchange resin pressure formed into a tablet for delivery to a bleeding wound. The tablet improves the rate of adhesion to a bleeding wound surface, and allows a significantly greater and more uniform pressure to be exerted by manual compression of the tablet on the wound site, as compared to that of a thin layer of scattered hemostatic powder. After the seal is formed from the interaction of blood or exudates with the immediate contacting surface of the tablet, the bulk of the unused tablet easily delaminates from the seal making clean up facile. If the unused portion of the tablet is not removed from the wound site, a reservoir of hemostatic dressing stops further bleeding and to provide antimicrobial protection and healing. The tablet may be applied to any surface orientation and take any shape and thickness possible.

  • Patent number: 9757412
    Abstract: A composition and method useful in promoting hemostasis, absorbing ooze, and being antimicrobial with respect to an open wound. The composition broadly includes an antimicrobial agent, preferably povidone iodine, preferably a ferrate compound, and a cation ion exchange resin. This composition will destroy a biofilm which has formed over the open wound in providing a soluble iron compound, a cation chelation compound, and an active antimicrobial compound effective against planktonic microorganisms and biofilms. The antimicrobial agent is locked or sealed within the scab formed over the wound to maintain long-term positioning and anti-dilution of the antimicrobial over the wound.

  • Patent number: 9039667
    Abstract: A method of arresting blood flow from a bleeding wound including the steps of (1) providing a solid hemostatic tablet preferably including potassium ferrate and a cation ion exchange resin pressure formed into a tablet for delivery onto a bleeding wound, the tablet defining a proximal portion and a distal portion, (2) applying the proximal portion against the bleeding wound to improve the rate of adhesion to a bleeding wound surface, and then (3) applying pressure against the tablet over the wound site. After the seal is formed from the interaction of blood or exudates with the proximal portion of the tablet, the distal portion of the tablet delaminates from the proximal portion to form a reservoir to stop further bleeding and to provide antimicrobial protection and healing. The tablet may be applied to any surface orientation and take any shape and thickness possible.

  • Patent number: 8979726
    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.

  • Patent number: 8110208
    Abstract: A hemostatic composition for stopping or decreasing blood flow from an open wound or medical or surgical procedure. Compositions of the invention comprise a mixture of a cationic polymer and a cation exchange material. In one embodiment, the composition comprises a mixture: (1) a high molecular weight copolymer of diallyl dimethyl ammonium chloride (DADMAC) and acrylamide [DADMAC copolymer], and (2) the hydrogen form of a crosslinked, sulfonated polystyrene (hydrogen resin). In an exemplified embodiment, a composition of the invention comprises the mixture of DADMAC copolymer and hydrogen resin provided in a dry powdered form. The compositions of the invention may be applied directly to a wound or treatment site, or they may be incorporated into a wound dressing, such as a bandage. The seal formed at a wound or treatment site treated with the present invention is adhesive and exhibits considerable toughness.

  • Patent number: 8007833
    Abstract: A method of reducing infections associated with vascular access procedures. A powder containment device (PCD) is preferably adhesively attached to a skin area, the PCD having a hole formed centrally therethrough adapted to completely surround the catheter wound site. The open cavity formed by the PCD being attached to the skin is filled with a hemostatic agent of a salt ferrate and an insoluble cation exchange material. The salt ferrate combines with blood to form a trivalent Fe+++ ion promoting blood clotting and producing oxygen at the wound site for bacteria reduction. The cation exchange material also forms a protective cover over the wound site as the trivalent Fe+++ ion is formed. Semi-occlusive pressure is applied against the hemostatic agent for a time sufficient to arrest blood flow from the wound site right after inserting or removing the catheter. The PCD and hemostatic agent are then covered with an adhesive dressing.

  • Patent number: 6521265
    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.
