A method of inhibiting the coagulation of blood during the extracorporeal circulation thereof by bringing a member for releasing an antithrombotic drug, prepared by dispersing a difficulty water-soluble antithrombotic drug in a macromolecular material, into contact with the circulating blood. A device for releasing an antithrombotic drug to be used in the above method comprises either the drug releasing member contained in a vessel provided with blood inlet and outlet ports at the respective ends thereof or the drug releasing member constituting at least the inner wall surface of the vessel. As the antithrombotic agent can be released sustainedly from the drug releasing member, the blood coagulation in the blood circuit can be inhibited as a result of the contact of the blood with the member during the extracorporeal circulation.
一种在体外循环过程中抑制血液凝固的方法,其方法是将通过在高分子材料中分散难溶于
水的抗血栓药物而制备的释放抗血栓药物的部件与循环血液接触。在上述方法中使用的抗血栓药物释放装置包括:药物释放部件装在一个容器中,容器的两端分别设有血液入口和出口;或者药物释放部件至少构成容器的内壁表面。由于抗血栓药物可从药物释放部件中持续释放,在体外循环过程中,血液与该部件的接触可抑制血路中的血液凝固。
