Gegenstand der Erfindung ist eine weitere Ausbildung der Atemmaske für Frischluftzuführung nach Patent 922 326. Bei der Atemmaske nach diesem Patent mündet die Frischluftzuführungsleitung in eine an dem Maskenraum angeschlossene Vorkammer, die mit der Umgebungsluft in Verbindung steht. Der Gerätbenutzer entnimmt dabei dem Luftstrom, der die Vorkammer durchströmt, immer nur so viel Luft, wie er zum Füllen der Lunge benötigt.The subject of the invention is a further embodiment of the breathing mask for fresh air supply according to Patent 922 326. In the breathing mask according to this patent, the fresh air supply line opens into an antechamber connected to the mask room, which communicates with the ambient air stands. The device user only takes from the air flow that flows through the antechamber as much air as it takes to fill the lungs.

Die Vorkammer kann nach einem der Ansprüche 7 bis 17 des Hauptpatents außerhalb des eigentlichen Maskenkörpers angeordnet und ganz oder teilweise durch einen die Frischluftzuführungsleitung umgebenden Raum gebildet sein.The antechamber can according to one of claims 7 to 17 of the main patent outside of the actual Mask body arranged and wholly or partially surrounded by a fresh air supply line Space.

Um zu verhindern, daß der Frischluftstrom auf eine bestimmte Stelle des Gesichtes gerichtet ist, wodurch unangenehme Unterkühlungserscheinungen erzeugt werden können, wird in weiterer Ausbildung — der Atemmaske nach dem Hauptpatent erfmdungsgemäß vor der Lufteintrittsöffnung des Luftzuführungsschlauches eine Prallfläche angeordnet.To prevent the flow of fresh air from being directed at a certain point on the face, which can cause unpleasant symptoms of hypothermia is in further training - the breathing mask according to the main patent according to the invention in front of the air inlet opening of the air supply hose arranged a baffle.

In der Zeichnung ist eine Ausführungsform der Erfindung schematisch dargestellt. Es zeigtAn embodiment of the invention is shown schematically in the drawing. It shows

Abb. 1 die als Halbmaske mit vergrößerter Vorkammer ausgebildete Atemmaske,Fig. 1 the breathing mask designed as a half mask with an enlarged antechamber,

Abb. 2 die Vorkammer im Schnitt durch die Ebene A-A der Abb. 1.Fig. 2 the antechamber in section through the plane AA of Fig. 1.

An dem nur zum Teil gezeichneten Maskenkörper 38 ist das Ausatemventil 39 befestigt. An dem im einzelnen nicht gezeichneten Mundstück 40 sind ein verhältnismäßig großer, die Vorkammer bildender Schlauch 41 und der in ihm liegende Luftzuführungsschlauch 42 befestigt. Vor der Mündung der Schläuche 41 und 42 ist in der Maske die Prallrläche 7 befestigt. Sie verhindert, daß der aus dem Luftzuführungs-Atemmaske für FrischluftzuführungThe exhalation valve 39 is attached to the mask body 38, which is only partially shown. On that in detail The mouthpiece 40, not shown, is a relatively large one that forms the antechamber Hose 41 and the air supply hose 42 lying in it attached. In front of the mouth of the hoses 41 and 42, the impact surface 7 is fixed in the mask. It prevents the breathing mask from getting out of the air supply for fresh air supply

schlauch kommende Frischluftstrom und die gegebenenfalls zusätzlich aus dem Schlauch 41 angesaugte Luft unmittelbar auf das Gesicht treffen. Die Frischluft strömt in Richtung des Pfeiles 46 zu und während der Ausatemphase in Richtung des Pfeiles 47 nach außen. Die Ausatemluft tritt durch das Ausatemventil 39 ins Freie.The fresh air flow coming from the hose and the airflow that may also be drawn in from the hose 41 Immediately hit the face with air. The fresh air flows in the direction of arrow 46 to and outward in the direction of arrow 47 during the exhalation phase. The exhaled air passes through the exhalation valve 39 outdoors.
