Zusammenfassung:A cannula comprising a plastic tube having three longitudinal chambers, including a main chamber, a first lateral chamber and a second lateral chamber, and at least one reinforced section ensuring constant internal diameter, wherein the cannula is equipped from the distal side with a round end narrowing towards the end, in which there are longitudinal holes of a size enabling free venous blood flow, and a balloon. A fragment of the reinforced tube section located below the balloon is bent under an angle α of approximately 90°. From the proximal side, the tube ends with a flexible cone, sealing the cannula tightly, inside which there is a valve closing the main chamber and a port for inflating the balloon connected to the first lateral chamber.
