METHOD OF OBTAINING ANTIMICROBIAL POLYURETHANE COATING ON POLYURETHANE ARTICLES AND METHOD FOR MANUFACTURING POLYURETHANE CATHETERS WITH ANTIMICROBIAL POLYURETHANE COATING

摘要

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.;3 cl, 1 tbl
