Description

Translated fromRussian

Предохранительные устройства к аппаратам дл  внутривенных переливаний , содержащие стекл нный капилл р и резиновые соединительные трубки, известны.,Safety devices for intravenous transfusion apparatus containing glass capillary and rubber connecting tubes are known.,

Предлагаетс  устройство дл  автоматического прекращени  подачи крови и кровезамен ющих жидкостей при внугривенных вливани х в тех случа х, когда по каким-либо причинам в трубку, по которой поступает кровь или кровезамен юща  жидкость, попадает воздух. Устройство отличаетс  тем, что оно снабжено фотодатчиком и реле, включающими одновременно электромагнитное зажимное устройство и светозвуковую сигнализаций. Така  конструкци  устройства увеличивает надежность процесса переливани , так как позвол ет автоматически мгновенно отключать аппарат при попадании воздуха в переливаемую жидкость.A device is proposed for automatically stopping the delivery of blood and blood replacement fluids for intravenous infusions in cases where, for whatever reason, air enters the tube through which blood or blood replacement fluid enters the tube. The device is characterized in that it is provided with a photosensor and a relay, which simultaneously includes an electromagnetic clamping device and light-sound signaling. This design of the device increases the reliability of the transfusion process, as it allows the device to instantly turn off automatically when air enters the liquid being poured.

На чертеже изображена принципиальна  схема предлагаемого устройства .The drawing shows a schematic diagram of the proposed device.

Устройство выполнено в виде приставки, состо щей из фотосопротивлени  /, выпр мител  и реле, смонтированных в кожухе 2, зажима 3 дл  резиновой трубки 4, электрических лампочек 5 и б и электрического звонка 7. Лампочка 5 служит дл  освещени  фотосопротивлени  /, а лампочка 6  вл етс  сигнальной. При работе система 5 заполн етс  соответствующей жидкостью. Если в стекл нной трубке 9, помещенной напротив фотосопротивлени  /, по вл етс  пузырек воздуха, то изменение величины тока, проход щего через фотосопротивление 1, заставл ет срабатывать реле, пережимающее резиновую трубку, одновременно загораетс  сигнальна  лампочка 6 и включаетс  звонок 7.The device is designed as an attachment consisting of photoresistance /, rectifier and relay mounted in housing 2, clamping 3 for rubber tube 4, electric lights 5 and 6, and electric bell 7. Light bulb 5 serves to illuminate photoresistance /, and light bulb 6 is signal. In operation, system 5 is filled with an appropriate fluid. If an air bubble appears in the glass tube 9 placed opposite the photoresistance /, a change in the magnitude of the current passing through the photoresistance 1 causes the relay that presses the rubber tube to operate, while the warning light 6 lights up and bell 7 comes on.

Томский государственный медицинский институт Министерства здравоохранени  РСФСР, проводивший испытани  предложенного устройства , дает ему положительную оценку и рекомендует к серийному выпуску.The Tomsk State Medical Institute of the Ministry of Health of the RSFSR, which tested the proposed device, gives it a positive assessment and recommends it for serial production.
