    摘要: A medical device includes a base material and chlorhexidine or a pharmaceutically acceptable salt thereof disposed in the base material sufficient to reduce microbial growth. The base material includes a polymer having a silicone monomer and a urethane monomer. To make the medical device having an antimicrobial agent, a silicone-urethane-carbonate polymer is dissolved in Dimethylformamide/Tetrahydrofuran (DMF/THF) to generate a coating solution, a chlorhexidine or a pharmaceutically acceptable salt thereof is mixed into the coating solution, a base material is coated with the coating solution, and the coating solution is dried to remove the solvent. The chlorhexidine is present in concentration sufficient to reduce microbial growth.
