Description
154) УСТРОЙСТВО ДЛЯ ПЕРЕЛИВАНИЯ КРОВИ154) DEVICE FOR BLOOD TRANSFUSION
ный эпемент 8 имеет меньшую поверхность в плече соединени трубки 10 с эластичным резервуаром 9, и по меньшей мере, с одной из боковых сторон эластичного резервуара.The transitional element 8 has a smaller surface in the shoulder of the connection between the tube 10 and the elastic reservoir 9, and at least on one of the sides of the elastic reservoir.
Устройство работает следующим образом . Внутрь шкафа 1 вставл ют эластичный резервуар 9 с жидкостью (например, с кровью) и дверцу 2 закрывают. Клапан 6 перекрывают нажатием ручки 12 вниз до упора. При помоши коммутируюших трубопроводов клапан соедин етс соответственно с.насосом 11, опорным элементом 7, выполненным в виде надувного резервуара, и с манометром 13. В зависимости от положени ручки 12 клапаном 6 регулируютс либо режим полного перекрыти , необходимый дл накачивани опорного элемента 7 пибо режим постепенного выпуска воздуха из опорного элемента 7 в атмосферу, либо режим мгновенного выпуска воздуха из опорного элемента 7 в атмосферу. После перекрыти клапана нагнетают воздух в опорный элемент 7 при помоши насоса 11. Величина давлени указываетс манометром 13. По мере увеличени давлени опорный элемент 7 своей боковой поверхностью 14 прижимаетс к эластичному резервуару 9, который оказываетс зажатым между опорными элементами 7 и 8. В эластичном резервуаре обычно содержитс не только жидкость, но и некоторое количеств. во пузырьков воздуха, попадание которых в вену человека через трубку 10 вл етс нежелательным. Предотвращение такой опао кости обеспечиваетс опорным элементом 8 которому придаетс конфигураци , показанна на фиг. 3 и фиг. 4. Применением опорного элемента 8 указанной формы достигаетс создание в эластичном резервуаре 9 одного горизонтального канала 15 и двух вертикальных каналов 16. По этим каналам беспреп тственно проход т пузырьки воздуха в верхнюю часть эластичного резервуара даже при полном его сжатии. Этим предотвращаетс попадание пузырьков воздуха в вену человека. Дл возможности визуального определени уровн жидкости в эластичном резервуаре 9 в дверйе корпуса предусматриваетс вырезное окно 17.The device works as follows. An elastic reservoir 9 with a liquid (for example, blood) is inserted inside the cabinet 1 and the door 2 is closed. The valve 6 is blocked by pressing the handle 12 down until it stops. With the aid of switching pipelines, the valve is connected respectively with a pump 11, a support element 7, made in the form of an inflatable tank, and a pressure gauge 13. Depending on the position of the handle 12, valve 6 regulates either the complete shutdown mode required for pumping the support element 7 or the gradual release of air from the support element 7 into the atmosphere, or the mode of instantaneous release of air from the support element 7 into the atmosphere. After the valve overlaps, air is pumped into the support element 7 by means of the pump 11. The pressure value is indicated by a pressure gauge 13. As the pressure increases, the support element 7 with its side surface 14 is pressed against the elastic tank 9, which is sandwiched between the support elements 7 and 8. In the elastic tank usually not only liquid, but also some amounts are contained. into air bubbles, the entry of which into the human vein through the tube 10 is undesirable. The prevention of such a danger is ensured by a support element 8 which is attached to the configuration shown in fig. 3 and FIG. 4. By using the support element 8 of the specified form, it is possible to create in the elastic tank 9 one horizontal channel 15 and two vertical channels 16. Through these channels air bubbles pass unhindered to the upper part of the elastic tank even when it is fully compressed. This prevents air bubbles from entering the human vein. In order to visually determine the level of the liquid in the elastic tank 9, a cut-out window 17 is provided in the housing door.
