POLYURETHANE CATHETER WITH ANTIMICROBIAL COATING, METHOD FOR PREPARING ANTIMICROBIAL COATING ON POLYURETHANE PRODUCTS AND METHOD FOR PRODUCING POLYURETHANE CATHETERS WITH ANTIMICROBIAL COATING Russian patent published in 2012 - IPC A61L27/14 A61L27/54 A61L29/06 A61L29/16 

FIELD: medicine.

SUBSTANCE: invention refers to medicine. High antimicrobial activity and desired smoothness providing high thromboresistance are ensured by modifying a product surface, e.g. a polyurethane polyurethane with chlorhexidine and/or its salts with the modification procedure ensured by applying 0.5-4% polyurethane of molecular weight 10000 to 40000 units. in tetrahydrofurane containing chlorhexidine and/or its salts in the amount 0.25-5% (wt) in relation to polyurethane weight that is followed by tetrahydrofurane evaporation.

EFFECT: what is described is a polyurethane catheter with antimicrobial coating, the method for preparing the antimicrobial coating on polyurethane products and the method for producing the polyurethane catheters with the antimicrobial coating.
