Изобретение относитс  к медицинской технике, а именно к протезам клапанов сердца.The invention relates to medical technology, namely to prosthetic heart valves.

Цель и:юбретени  снижение нагрузки на сердце.Aim and: to celebrate reducing the load on the heart.

На фиг. 1 показан опорный каркас протеза в виде пружины; на фиг. 2 протез клапана, разрез.FIG. 1 shows the support frame of the prosthesis in the form of a spring; in fig. 2 valve prosthesis, incision.

Протез клапана сердца содержит опорный каркас с нижним 1 и верхним 2 кольцами , которые соединены цилиндрической пружиной 3. Внутри нижнего кольца 1 находитс  дополнительное укрепл ющее кольцо 4. Все элементы опорного каркаса выполнены из гибкого упругого гемосовмести- мого материала. В каркасе закреплен клапан , выполненный из биосов.местимого материала , состо щий из запорного элемента с трем  створками 5 оболочки 6 с трем  синусо- образными выступами и цилиндрический участок 7, в который переход т оболочки 6. Торец цилиндрического участка 7  вл етс  верхним краем 8 протеза, а нижним краем 9  вл етс  место креплени  оболочки 6 между нижним 1 и дополнительным укрепл ющи.м 4 кольцами. Створки 5 запорного элемента расположены над кольцами 1 и 4 по линии 10 креплени  створок 5 к обо.чочке 6. Причем оболочка 6 выполнена из биологического трансплантата, а его цилиндрический участок 7 выбирают длиной, равной не менее диаметра опорного каркаса.The prosthetic heart valve contains a support frame with lower 1 and upper 2 rings, which are connected by a cylindrical spring 3. Inside the lower ring 1 there is an additional reinforcing ring 4. All elements of the support frame are made of flexible elastic hemocompatible material. A valve made of biocompatible material, consisting of a locking element with three flaps 5 sheath 6 with three sinus-shaped protrusions and a cylindrical section 7, into which the shells pass 6, is fixed in the frame. The end of the cylindrical section 7 is the upper edge 8 the prosthesis, and the lower edge 9 is the place of attachment of the sheath 6 between the lower 1 and the additional reinforcement m 4 rings. The flaps 5 of the closure element are located above the rings 1 and 4 along the line 10 of the fastening of the flaps 5 to the obnochochke 6. Moreover, the shell 6 is made of a biological graft, and its cylindrical section 7 is chosen of a length equal to not less than the diameter of the support frame.

Протез работает следующим образом.The prosthesis works as follows.

При возрастании давлени  со стороны желудочка верхнее кольцо 2 перемещаетс As the ventricular pressure increases, the upper ring 2 moves

К моменту окончани  изгнани  крови их желудочка створкиupward along the axis of the valve (Fig. 2) and the spring rings 3 move upwards, which contributes to the uplift of the valves 5 of the closure element, therefore the doors have a small resistance to blood flow. The additional ring 4 retains the shape of the bore hole and contributes to the uniform distribution of the loads on the fibrous ring at the base of the valve. By the end of the expulsion of the blood of their ventricular valves
