Atmungsvorrichtung.
Die Erfindung bezieht sich auf eine Atmungsvorrichtung. bei welcher, wie etwa nach dem österr.
Patent Nr. 68 561, an die Maske einerseits eine Frischluft-oder Sauerstoffzuleitung und anderseits eine durch ein Rückschlagventil abgeschlossene Ableitung für die ausgeatmete Luft vorgesehen ist.
Bei Vorrichtungen dieser Art kommt es vor. dass während der kurzen Zeit des Ventilhubes an) Aus- atmungsrohr, insbesondere während einer Periode heftiger Atmungstätigkeit, wo zufolge ungenügender Frischluftzufuhr der Druck in der Maske sinkt, Gase (z. B. Kohlenoxydgas) aus dem Raum, in welchem

wird, in welche das bis nahe auf den Boden der Vorlage reichende.Ableitungsrohr für die ausgeatmete Luft luftdicht eingesetzt ist. Das Rückschlagventil ist an der äusseren Mündung des Ableitungsrohres eingesetzt. Etwa durch das Ventil eindringende Gase sammeln sich in der Vorlage an und werden beim Wiederansteigen des Druckes innerhalb der Maske durch die ausgeatmete Luft wieder ausgespült.
Die Zeichnung zeigt in sehematischer Weise die Anordnung nach der Erfindung.
Die Maske 4 steht in bekannter Weise durch das Rohr 3 mit dem Atmungssack 6 in Verbindung.

Breathing device.
The invention relates to a breathing device. in which, such as after the Austrian
Patent No. 68,561, on the one hand a fresh air or oxygen supply line and on the other hand a discharge line for the exhaled air closed by a check valve is provided on the mask.
It happens with devices of this type. that during the short time of the valve stroke on) the exhalation tube, especially during a period of vigorous breathing activity, where the pressure in the mask drops due to insufficient fresh air supply, gases (e.g. carbon oxide gas) from the room in which
EMI1.1
into which the drainage pipe for the exhaled air, which reaches close to the bottom of the template, is inserted airtight. The check valve is inserted at the outer mouth of the discharge pipe. Any gases that penetrate through the valve collect in the template and are flushed out again by the exhaled air when the pressure inside the mask rises again.
The drawing shows in a schematic way the arrangement according to the invention.
The mask 4 is connected to the breathing bag 6 in a known manner through the tube 3.
EMI1.2
the template 5 follows. into which the exhalation tube 8 provided with the check valve 7 is inserted.
