Abstract

Abstract Translated from German Eine Vorrichtung zur Hochfrequenzbeatmung lebender Tiere oder Menschen, umfassend einen in die Luftröhre einführbaren, flexiblen Tubus mit einem lungenseitigen Auslaß, eine durch ein Ventil abschließbare Luftleitung (34) sowie Hilfseinrichtungen (76, 77) zur Einspeisung von Beatmungsluft erhöhten Druckes in die Beatmungsluftleitung (34). Das Ventil ist am lungenseitigen Ende (42) der Beatmungsluftleitung (34) angeordnet und dient zugleich als Ejektordüse für die Abführung von verbrauchter Luft durch den Tubus, wenn dieser als Auslaßleitung dient. A device for high-frequency ventilation of living animals or humans, comprising a flexible tube that can be inserted into the trachea and has a lung-side outlet, an air line (34) that can be closed by a valve, and auxiliary devices (76, 77) for feeding ventilation air of increased pressure into the ventilation air line (34 ). The valve is arranged on the lung-side end (42) of the ventilation air line (34) and at the same time serves as an ejector nozzle for the discharge of used air through the tube when it serves as an outlet line.
