Abstract
Изобретение относитс к медицинской технике , в частности, к протезированию аорты и легочной артерии. Цель изобретени - снижение тромбообразовани путем оптимизации геометрических параметров протеза, который состоит из входного цилиндрического участка, армированного пружиной 5, выходного цилиндрического участка 3 с кольцом 6 на выходе и диффузорного участка с углом конусности 10±5°. Благодар большему диаметру выходного участка 3 возможно использование клапана 4 с большим проходным отверстием, что снижает потери в протезе, а конусный участок предотвращает образование отрывных зон. 2 ил.This invention relates to a medical technique, in particular, prosthetics of the aorta and the pulmonary artery. The purpose of the invention is to reduce thrombosis by optimizing the geometrical parameters of the prosthesis, which consists of an inlet cylindrical section reinforced by a spring 5, an outlet cylindrical section 3 with a ring 6 at the outlet and a diffuser section with a taper angle of 10 ± 5 °. Due to the larger diameter of the outlet section 3, it is possible to use the valve 4 with a large through-hole, which reduces the loss in the prosthesis, and the conical section prevents the formation of tear-off zones. 2 Il.
