PROBLEM TO BE SOLVED: To provide a composition, system, articles and method for the enhancement of clotting in wounds with extravascular blood flow, especially where the surface of tissue has been broken.SOLUTION: The method for enhancing the formation of clots on a wound of an animal where blood is present comprises the steps of applying porous particles having average diameter dimensions of from about 0.5 to 1,000 micrometers to at least a portion of the wound where blood is present in the wound, allowing the porous particles to remain in contact with the blood in the wound while clotting initiates in the wound.COPYRIGHT: (C)2012,JPO&INPIT【課題】血管外、特に組織の表面が破壊された場所での血流を伴う傷における凝血の増強のための組成物、系、物品及び方法の提供。【解決手段】血液が存在する動物の傷の上での凝血塊の形成を増強するための方法であって、約0.5~1000マイクロメーターの平均直径寸法を有する多孔性粒子を、血液が存在する前記傷の少なくとも一部に対し適用する段階、凝血が前記傷で開始している間、前記多孔性粒子を前記傷中の血液と接触したまま留める段階、を含んで成る方法。【選択図】なし
