Description

Изобретение относитс  к медицине, точнее к протезам анатомических органов .This invention relates to medicine, more specifically to prostheses of anatomical organs.

Цель изобретени  - уменьшение травмы форменных элементов крови и снижение потери энергии потока крови путем вьфавнивани  пол  скоростей по длине канала протеза и создани  устойчивой структуры потока.The purpose of the invention is to reduce the injury of the blood cells and reduce the loss of energy of the blood flow by increasing the sex velocity along the length of the prosthesis canal and creating a stable flow structure.

На чертеже изображен протез легочной артерии.The drawing shows a prosthetic pulmonary artery.

Протез легочной артерии состоит из изогнутого отрезка протеза 1 сосуда конфузорной формы со спиральными гофрами 2 переменного шага и кла-т пана 3. Минимальный допустиньш радиус кривизны, при котором происходит безотрывное течение в изогнутом канале, более 2,23 его диаметра. Переменный шаг гофра мм, а кон- фузорность канала с углом конусности 2,5-3,5° снижает потери энергии в устройстве и .выравнивает поле скоростей потока.A prosthesis of the pulmonary artery consists of a curved section of the prosthesis of 1 vessel of confused form with spiral corrugations 2 of variable pitch and valve 3 pane 3. The minimum tolerance radius of curvature at which a continuous flow occurs in the curved canal is more than 2.23 of its diameter. The variable pitch of the corrugation is mm, and the confusion of the channel with a taper angle of 2.5-3.5 ° reduces the energy loss in the device and equalizes the flow velocity field.

Искусственный клапан 3 :с шаровым запорным элементом не индуцирует за собой вихревые застойные зоны и не разрушает структуру закрученного потока .Artificial valve 3: with ball stop element does not induce vortex stagnation zones behind it and does not destroy the structure of the swirling flow.

Устройство работает следующим образом .The device works as follows.

После вшивани  протеза легочной g артерии поток крови закручиваетс  на спирал х гофра с переменным шагом и открывает искусственный клапан, причем на выходе протеза получаетс  слабозакрученный устойчивый поток 10 крови с выравненным полем скоростей близкий к физиологическому.After lung g artery prosthesis is stitched, the blood flow twists on corrugated spirals with a variable pitch and opens an artificial valve, and at the exit of the prosthesis a weakly wound stable blood flow 10 with a uniform velocity field is close to physiological.
