Claims (5)

(54) ОКСИГЕНАТОР Обедненна  кисло|юдом венозна  кровь поступает в эжектор I но трубам 10 через отверсти  в. Кислород выходит из головки 11 диффузора 2, образу  в крови пузырьки одинаковога размера. При этом эжектор действует как нузырьковый насос. Когда пузырьки кислорода смешаны с кровью и начинаетс  диффузи , вокруг каждого пузырька образуетс  граничный слой кр ви, насыщенной кислородом, который преп тствует дальнейшей диффузии. По мере соприкосновени  такого нузырька с шариком 5 граничный слой разрушаетс  и диффузи  продолжаетс . Окисленна  кров на  пена соприкасаетс  с отбойкиком 7 и поступает в пеногаситель. При этом пузьфьки, содержашие двуокись углерода и кислород , оседают на смачивающихс  волокнах ткани 8, перемешаютс  в резервуар 12 и выпускаютс  в атмосферу через отверсти  б. Окисленна  кровь вытекает из пеногасител  и протекает по теплообменнику 13, где поддерживаетс  температура крови на заданном уровне. Далее она попадает в рюзерк вуар 12 и через клапан 9, вьтускное отверстие 3, патрубок 14 удал етс  наружу. Формула изобретени  1. Оксигенатор, содержащий эжектор, диффузор , оксигеннрующий цилиндр, пеногасительную камеру с пеногасителем, резервуар дл  накоплени  крови, теплообменник, вьшускные и впускные отверсти  дл  крови и газа, отличающийс   тем, что, с делью повышени  насыщени  крови кислородом, эжектор вьшо;шен с вогнутыми стенками , диффузор расположен в узкой части эжектора , оксигенирую1дий цилиндр снабжен с торцов сеткой и содержит множество жестких одинакового размера шариков, пеногаситель состоит из множества витков ткани, намотанной на верхнюю часть оксигенирующего цк.гшндра и состо щей из смачивающихс  и несмачивающихс  волокон. (54) OXIGENATOR Venous blood, depleted in acidic acid, enters the ejector I but pipes 10 through holes in the. Oxygen comes out of the head 11 of the diffuser 2, forming bubbles of the same size in the blood. At the same time, the ejector acts as a nosing pump. When oxygen bubbles are mixed with blood and diffusion begins, a boundary layer of oxygenated oxygen is formed around each bubble, which prevents further diffusion. As such a bubble contacts the ball 5, the boundary layer is destroyed and diffusion continues. The oxidized shelter on the foam is in contact with the binder 7 and enters the defoamer. At the same time, carbon dioxide containing oxygen and oxygen are deposited on the wetting fibers of the fabric 8, mixed into the tank 12 and released into the atmosphere through the holes b. The oxidized blood flows out of the defoaming agent and flows through the heat exchanger 13, where the blood temperature is maintained at a predetermined level. Further, it enters the reucer voyue 12 and through the valve 9, the through hole 3, the nozzle 14 is removed to the outside. Claims 1. An oxygenator comprising an ejector, a diffuser, an oxygen cylinder, a defoamer with an antifoam, a reservoir for accumulating blood, a heat exchanger, outlets and inlets for blood and gas, characterized in that to increase the oxygen saturation, the ejector is higher; with a concave wall, the diffuser is located in the narrow part of the ejector, the oxygenating cylinder is provided with a grid at the ends and contains many rigid balls of the same size, the defoamer consists of many turns of fabric, is wound on the upper part of the oxygenating complex, and consisting of wettable and non-wettable fibers. 2.Оксигенатор по п.1, отличающийс   тем, что смачивающиес  и несмачиваюшлес  волокна направлены под углом 90° одно к другому . 2. An oxygenator according to claim 1, characterized in that the wettable and non-wetting fibers are directed at an angle of 90 ° to each other. 3.Оксигенатор, по п.1, отличающийс   тем, пo витки ткани пеногасител  содержат чередующиес  смачивающиес  и несмачивающиес  спои. 3. The oxygenator according to claim 1, characterized in that the coils of the defoaming agent tissue contain alternate wettable and non-wettable spy. 4.Оксигенатор по п.1, отличающийс  тем, что пеногасительна  камера снабжена отбойником , а вьтускное отверстие дл  крови выпол- г нено с предохранительным клапаном. 4. An oxygenator according to claim 1, characterized in that the antifoaming chamber is provided with a baffle bar and the blood outlet hole is provided with a safety valve. 5.Оксигенатор по п.1, отличающийс   тем, что жесткие шарики, расположенные в окгигенирующем цилиндре, скреплены между собой.5. The oxygenator according to claim 1, wherein the hard balls located in the enrichment cylinder are bonded to each other.
