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.

Claims (1)

Формула изобретенияClaim Протез артерии, содержащий клапан и состоящий из входного цилиндрического участка, конического диффузорного участка и выходного цилиндрического участка, причем поперечное сечение входа меньше поперечного сечения выхода, а клапан установлен на выходном участке на расстоянии не менее половины диаметра этого участка от выхода, отличающийся тем, что, с целью снижения тромбообразования путем оптимизации геометрических параметров протеза, угол конусности диффузорного участка составляет 10+5°, клапан расположен на рас’ стоянии не менее половины диаметра выходного цилиндрического участка от окончания конического диффузорного участка, а отношение выходного диаметра протеза к входному составляет ( 1 + 2/dв>)-(1+ 10/dBK) , где dex диаметр входного цилиндрического участка.An artery prosthesis comprising a valve and consisting of an inlet cylindrical portion, a conical diffuser portion and an outlet cylindrical portion, wherein the inlet cross section is smaller than the outlet cross section, and the valve is installed in the outlet portion at a distance of at least half the diameter of this portion from the outlet, characterized in that , in order to reduce thrombosis by optimizing the geometric parameters of the prosthesis, the cone angle of the diffuser section is 10 + 5 °, the valve is located at a distance of at least floors the diameter of the output cylindrical section from the end of the conical diffuser section, and the ratio of the output diameter of the prosthesis to the input is (1 + 2 / d in> ) - (1 + 10 / d BK ), where d ex is the diameter of the input cylindrical section.
