Abstract: Изобретение относится к медицине, а именно к лечению воспалительных заболеваний уретры. Цель изобретения сокращение сроков лечения за счет повышения эффективности воздействия на слизистую уретры. Способ лечения уретритов заключается в следующем. В уретру вводят ирригатор, содержащий вставки из магнитомягкого материала, орошают слизистую уретры лекарственным препаратом и воздействуют на ирригатор поперечным магнитным полем, движущимся вдоль ирригатора к наружному концу уретры, причем частота магнитного поля составляет 20 50 Гц, напряженность 150 500 Э, длительность воздействия выбирают в пределах 5 7 мин. Поперечные вибрации ирригатора внутри канала уретры позволяют, в частности, улучшить условия для ирригации и аспирации препарата за счет расширения канала. Устройство для лечения уретритов содержит эластичный трубчатый ирригатор 3 с отверстиями 4 на боковой поверхности, снабженный цилиндрическими вставками из магнитомягкого материала, и источник магнитного поля, выполненный в виде ряда электромагнитов на Г-образных сердечниках 2, образующих желоб.

Granted: 1995-04-30
Abstract: FIELD: plastics production. SUBSTANCE: when initial material has been stirred in plastic processing machine under temperature and pressure conditions, enabling foaming of plastic after drop of pressure, plastic coming out of machine is transferred directly into cooling zone. Plastic is cooled with formation of continuous mixture featuring heavy viscosity and rigidity and possessing approximately "flat" profile of flow speed under pressure created by upstream-directed pressure element. After cooling zone, plastic is transferred as mildly as possible into retarding and delaying zone. Upstream-directed pressure element, which appears in this case, will increase pressure in plastic material, which is in the previous zones, to the level which prevents foaming of plastic. After plastic is transferred into warming up, foaming and moulding zones, controlled foaming is performed until plastic acquires required densitу. EFFECT: improved efficiency. 2 dwg
