Description
Mundstück für Atemgeräte, insbesondere Höhenatemgeräte Die Erfindung betrifft ein für Atemgeräte, insbesondere Höhenatemgeräte, bestimmtes Mundstück, das eine vorzugsweise aus Gummi bestehende Mundstückhülse aufweist, die auf das einen elliptischen oder ähnlichen Querschnitt. aufweisende Sauerstoffzuführungsrohr aufgeschoben ist.Mouthpiece for breathing apparatus, in particular high altitude breathing apparatus The invention relates to a mouthpiece intended for breathing apparatus, in particular high altitude breathing apparatus, which has a preferably made of rubber mouthpiece sleeve which is attached to the an elliptical or similar cross-section. having oxygen supply tube is postponed.
Die Erfindung besteht darin, daß die Mundstückhülse zwei Flansche aufweist, von denen der innere Flansch an der Rückseite der Vorderzähne oder des ganzen Gebisses anliegt, während der äußere Flansch sich vor den Lippen befindet und mit einer an den Lippen anliegenden Wärmeschutzschicht versehen ist. An dem inneren Flansch kann eine mit diesem aus einem Stück bestehende, die Zunge übergreifende Platte angebracht sein.The invention consists in that the mouthpiece sleeve has two flanges has, of which the inner flange on the back of the front teeth or the entire dentition, while the outer flange is in front of the lips and is provided with a heat protection layer lying on the lips. To the inner flange can be a one-piece with this, overlapping the tongue Plate be attached.
Das neue Mundstück läßt sich mit den Zähnen leicht festhalten, da die beiden Flansche das Verrutschen des Mundstückes im Munde verhindern. Der äußere Flansch, der mit einer an den Lippen anliegenden Wärmeschutzschicht versehen ist, schützt die Lippen wirksam gegen Kälte, was bei einem Höhenatemgerät, das bei sehr tiefen Temperaturen der Außenluft benutzt wird, von großer Wichtigkeit ist. Der an der Rückseite der Vorderzähne oder des ganzen Gebisses anliegende innere Flansch verhindert außerdem, daß die gegen Kälte empfindlichen Zähne von dem kalten Sauerstotistrom bestrichen werden.The new mouthpiece can easily be held in place with your teeth, there the two flanges prevent the mouthpiece from slipping in the mouth. The outer one Flange, which is provided with a heat protection layer on the lips, protects the lips effectively against the cold, which is the case with a high-altitude breathing apparatus the low temperatures of the outside air is of great importance. Of the inner flange resting against the back of the front teeth or of the entire dentition also prevents the teeth, which are sensitive to the cold, from the cold flow of oxygen be coated.
In der Zeichnung ist ein Ausführungsbeispiel des neuen Mundstückes dargestellt. Abb. i zeigt einen senkrechten Längsschnitt durch das Mundstück, und Abb. z ist eine Ansicht des Mundstückes von hinten.In the drawing is an embodiment of the new mouthpiece shown. Fig. I shows a vertical longitudinal section through the mouthpiece, and Fig. Z is a rear view of the mouthpiece.
Auf das Sauerstoffzuführungsrohr a, das einen nahezu elliptischen Querschnitt hat und an seinem Ende mit einem Flansch c versehen ist, ist die aus Gummi bestehende Mundstückhülse e bis an den Flansch c heran aufgeschoben. Die Mundstückhülse e hat zwei Flansche b und d; der innere Flansch b liegt an der Rückseite der Vorderzähne oder des ganzen Gebisses an, während der sich vor den Lippen befindende äußere Flansch d mit einer Wärmeschutzschicht h versehen ist, die an beiden Lippen anliegt und diese dadurch gegen Kälte schützt. An dem inneren Flansch b ist eine mit diesem aus einem Stück bestehende Plattei angebracht, die in bekannter Weise die Zunge übergreift und den Abfluß des Speichels in die Atemöffnung des Mundstückes verhindert. An der Mundstückhülse e sind ferner die beiden federnden Halter/ befestigt, die zum Verschließen der Nasenlöcher dienende Pfropfen g tragen.The mouthpiece sleeve e made of rubber is pushed onto the oxygen supply tube a, which has an almost elliptical cross section and is provided with a flange c at its end, up to the flange c. The mouthpiece sleeve e has two flanges b and d; the inner flange b rests on the back of the front teeth or the entire set of teeth, while the outer flange d in front of the lips is provided with a heat protection layer h that rests on both lips and thereby protects them against the cold. On the inner flange b there is attached a plate consisting of one piece with the latter, which, in a known manner, engages over the tongue and prevents the outflow of saliva into the breathing opening of the mouthpiece. On the mouthpiece sleeve e, the two resilient holders / are also attached, which carry plugs g used to close the nostrils.
