PROBLEM TO BE SOLVED: To improve convenience, flexibility, retainability of antithrombogenic performance and antibacterial performance of an antibacterial antithrombogenic material, by making the material contain liposoluble mucopolysaccharide consisting of at least one kind of mucopolysaccharide and an ionic complex of quaternary phosphonium and aliphatic polyurethane as indispensable components. SOLUTION: This antibacterial antithrombogenic material makes an ionic complex of at least one kind of mucopolysaccharide, such as heparin, and quaternary phosphonium as one indispensable component. Aliphatic polyurethane is made as the other indispensable component. Both indispensable components are made contained in the material. The antibacterial antithrombogenic material made by such a manner is induced into a polymer material, in which liposoluble mucopolysaccharide makes aliphatic polyurethane as at least one of its components, to make the surface inactive. The material performs controlled releasing to demonstrates antibacterial and antithrombogenic performance. Thus controlled releasing is controlled to retain antithrombogenic performance for a long time and antibacterial performance can be obtained by the effect of quaternary phosphonium. |
