METHOD FOR MAKING ANTIMICROBIAL-COATED TUBULAR PRODUCTS, METHOD FOR PREPARING ANTIMICROBIAL COATING ON POLYURETHANE CATHETERS, PREFERENTIALLY MULTIPLE-LUMEN ONES, AND ANTIMICROBIAL-COATED MULTIPLE-LUMEN CATHETER Russian patent published in 2014 - IPC A61L29/06 A61L29/16 A61L27/14 A61L27/54 

FIELD: medicine.

SUBSTANCE: invention refers to medicine. What is described is a method for measuring antimicrobial-coated tubular polyurethane products, including multiple-lumen polyurethane catheters consisting in the three-staged chlorhexidine and/or its salts modification. Chlorhexidine and/or its salts are impregnated on the product surface by processing the products in aqueous-alcohol solutions of chlorhexidine and/or its salts, removing excessive chlorhexidine and/or its salts from the product surface, applying a solution of polyurethane in tetrahydrofurane containing chlorhexidine and/or its salts, and evaporating tetrahydrofurane.

EFFECT: preparing the polyurethane products, eg catheters possessing the prolonged antimicrobial activity being in full accord with the multifunctionality of the multiple-lumen catheters.
