  • Molecular sieve materials having increased particle size for the formation of blood clots
    Publication number: 20060141060
    Abstract: A composition for clotting blood comprises a molecular sieve material. The molecular sieve material is in the form of particles, the particles having an average diameter of about 0.2 millimeters (mm) to about 10 mm. The molecular sieve material may be a zeolite, the zeolite being an aluminosilicate comprising at least one of calcium and sodium.

  • Calcium zeolite hemostatic agent
    Publication number: 20050074505
    Abstract: A composition for promoting the formation of clots in blood comprises a binder and a zeolite disposed in the binder, the zeolite having an adjusted calcium content. A method of forming a blood-clotting composition comprises the steps of providing a zeolite, combining the zeolite with a binder, and adjusting a calcium content of the zeolite to have an amount of calcium such that upon application of the composition to a wound, a heat of hydration is reduced and thereby heat transferred to the wound is reduced. A method of clotting blood flowing from a wound comprises the steps of applying a zeolite to the wound and maintaining the zeolite in contact with the wound for a predetermined amount of time. The zeolite preferably has an adjusted calcium content and is capable of producing a controllable blood clotting effect on the wound.

  • Partially hydrated hemostatic agent
    Publication number: 20050058721
    Abstract: A composition for promoting the formation of clots in blood comprises a zeolite and a binder. The zeolite is adjusted to have a specific moisture content. Processes by which the moisture content is adjusted include drying, re-hydrating, and combinations of drying and re-hydrating. A method of forming the composition comprises the steps of providing a zeolite and adjusting the moisture content such that upon application of the composition to a wound, a heat of hydration is reduced and heat transferred to the wound is reduced. A method of clotting blood flowing from a wound comprises the steps of applying the zeolite to the wound and maintaining the zeolite in contact with the wound for a predetermined amount of time, the zeolite having an adjusted moisture content and being capable of producing a controllable exothermic effect on the wound.
