Abstract: The present invention relates to an anti-microbial or anti-coagulating polymer resin and a method for preparing the same, and a medical appliance or instrument using the same, and more particularly to a method for preparing an anti-microbial or anti-coagulating medical polymer resin comprising the steps of simply mixing a polymer resin with at least one kind of pharmaceutically active material without using a solvent. The pharmaceutically active material is preferably an anti-microbial or anti-coagulant. According to the present invention, an anti-microbial or anti-coagulating material that is safe to a human body is mixed with a polymer resin by simple addition in an environmentally favorable non-solvent method, thereby maintaining superior anti-microbial effects even after high temperature molding, minimizing a released amount of anti-microbial to increase anti-microbial effect durability, and solving a toxic problem in a body.
