FIELD: medicine.SUBSTANCE: group of inventions refers to medicine. In a method for making an antimicrobial silver-containing endoprosthesis according to the 1 version, a mesh material is made of synthetic polymer fibres with a silver-containing composition in a solution, dried; the endoprosthesis made of polyvinylidene fluoride monofilaments of the diameter of 0.09-0.15 mm in the form of a form-stable combined weaved knitted cloth at surface density of the endoprosthesis 80-200 g/m, processed for 2-4 hours in 3-15% silver nitrate solution in dimethylsulphoxide, dried in air for 17-20 hours, processed again, dried, additionally processed in the composition consisting of 4-8 wt % of aqueous sodium hydroxide, 6-10 wt % of aqueous ammonium and 0.3-0.7 wt % of aqueous glucose in proportions 100:4:4, at temperature 20-25°C, and then washed in water, and dried. According to the 2 version, the endoprosthesis made of polypropylene monofilaments of the diameter of 0.07-0.15 mm, at surface density 20-120 g/m, processed in 5-15% silver nitrate solution in dimethylsulphoxide, dried for 5-8 hours, processed again, dried, processed in the composition (as provided by the first version) in proportions 100:7:9 at temperature 20-25°C, and then washed in water, and dried.EFFECT: group of inventions provides prolonged antimicrobial action of the endoprosthesis.2 cl, 2 tbl, 3 dwg |
