20080254146 | METHOD OF PROVIDING HEMOSTASIS IN ANTI-COAGULATED BLOOD - A method of clotting blood includes the step of administering a therapeutically effective amount of a composition comprising zeolite as the active ingredient to a wound from which the blood emanates. A method of arresting blood flowing from a wound includes the steps of providing a patient being inflicted with a bleeding wound and administering a therapeutically effective amount of a composition comprising zeolite as the active ingredient to the bleeding wound. A method of facilitating the formation of blood clots includes the step of contacting blood with a negatively charged surface wherein upon contacting the blood with the negatively charged surface a clotting mechanism is initiated. In any of the foregoing methods, the blood has a compromised ability to form clots. The blood may be from a person diagnosed with hemophilia or von Willebrand disease. | 10-16-2008 |
20080254147 | METHOD OF PROVIDING HEMOSTASIS IN ANTI-COAGULATED BLOOD - In a method of clotting blood in which the blood exhibits a reduced tendency to clot and may be from a person undergoing an anticoagulant therapy or having type A or B hemophilia or von Willebrand disease, a therapeutically effective amount of a composition comprising clay as the active ingredient is administered to a wound from which the blood emanates. Upon contacting the blood, this clay, which may be kaolin, bentonite, or any type of layered clay, causes the blood to clot. In a method of arresting blood flowing from a wound, a therapeutically effective amount of a composition comprising clay as the active ingredient is administered to the bleeding wound. In this method, the blood has a reduced tendency to clot and may be from a person undergoing an anticoagulant therapy or having at least one of hemophilia A or B or von Willebrand disease. | 10-16-2008 |
20090162406 | WOUND HEALING WITH ZEOLITE-BASED HEMOSTATIC DEVICES - A method for decreasing the time it takes for a wound to heal includes applying hemostatic agent to the wound, inflaming tissue surrounding the wound to facilitate the deposition of fibroblast, thereby accelerating the subsequent contraction of the wound and the onset of the proliferative healing stage, and causing the re-epithelization of the tissue at a faster rate than if no hemostatic agent was applied. A method for promoting the healing of a bleeding wound includes coating a hemostatic agent onto a substrate, applying the substrate to the bleeding wound so that an effective amount of the hemostatic agent is applied to the wound, inflaming the tissue, and causing the re-epithelization of the tissue at a faster rate than if no hemostatic agent was applied. In at least some methods, a clotting cascade and platelet aggregation within the bleeding wound is accelerated, and blood loss from the wound is decreased. | 06-25-2009 |
