<p>The invention relates to an air trap for closing synthetic tubes, especially infusion tubes, which air trap, for example in blood transfusion, reliably provides for an automatic closing-off of the blood supply if air bubbles appear in the infusion tube. For this purpose, the air trap for closing synthetic tubes, especially infusion tubes, has a flat head which, under the action of a spring, on the one hand bears against the membrane (Teflon membrane) of a pressure chamber while, on the other hand, it engages with its guide rod around a tube passage in such a way that, when there is a gas pressure in the chamber, the tube passage is cleared and, when the chamber is free of pressure, the tube passage is closed off with engagement by the guide rod under the action of a spring. …<IMAGE>… </p> |
