Полиуретановая композиция для перевязочного материала состоит из полиольного и изоцианатного компонентов. Полиольный компонент содержит высокомолекулярный олигоэфиртриол (100 мас.ч.), низкомолекулярный олигоэфирдиол (1,0 - 3,0 мас.ч.), воду (1,5 - 5,3 мас.ч.) и катализатор уретанообразования (0,3 - 0,8 мас.ч.). Изоцианатный компонент представляет собой олигоэфируретанизоцианат, полученный из олигоэфирполиолов и толуилендиизоцианата (ТДИ) или его смеси с полифениленполиметиленполиизоцианатами и растворенный в избытке ТДИ. Изоцианатный компонент содержит 16,8 - 34,5,5 мас.% NСО-групп и используется в количестве 29,4 - 163,6 мас.ч. на 100 мас.ч. полиольного компонента. Повязку создают непосредственно на раневой поверхности нанесением на нее перемешанной композиции до начала гелеобразования.Polyurethane dressing composition consists of a polyol and isocyanate components. The polyol component contains a high molecular weight oligoether triol (100 parts by weight), a low molecular weight oligoester diol (1.0 to 3.0 parts by weight), water (1.5 to 5.3 parts by weight) and a catalyst for urethane formation (0.3 - 0.8 parts by weight). The isocyanate component is an oligoether reanisocyanate derived from oligoether polyols and toluene diisocyanate (TDI) or its mixtures with polyphenylene polymethylene polyisocyanates and dissolved in excess TDI. The isocyanate component contains 16.8 to 34.5.5 wt.% Of the NCO-groups and is used in the amount of 29.4 to 163.6 wt.h. per 100 wt.h. polyol component. A bandage is created directly on the wound surface by applying a mixed composition on it prior to gelation.
