A method of preventing blood coagulation in the extracorporeal circulation of blood, and a method of inhibiting blood coagulation during extracorporeal blood circulation and device for releasing antithrombotic drug used therein,

摘要

A method for preventing blood coagulation during extracorporeal circulation of blood by contacting an antithrombotic drug releasing member formed by dispersing an anti-thrombotic drug resistant to water in a polymer material, with circulating blood, and a method for preventing blood coagulation during blood coagulation, Wherein the drug releasing member comprises at least a drug releasing member contained in the container, or at least a drug releasing member constituting the inner wall surface of the container. Since the fragrant thrombotic agent can be continuously released from the drug releasing member, blood clotting in blood circulation can be prevented as a result of contact between the member and blood during extracorporeal circulation.
