Description

Atenunaske, insbesondere für Höhenatemgeräte Die Erfindung betrifft eine Atemmaske, die insbesondere für Höhenatemgeräte bestimmt ist. Es sind bereits Atemmasken dieser Art bekannt, bei denen das Ausatemventil durch eine Lederhülle geschützt ist, die den obern, das Ausatemventil .enthaltenden Teil des Atemschlauches lose umschließt. Die warme Ausatemluft umspült das Ventilgehäuseund schützt es gegen Einfrieren. Diese Anordnung ist nicht zuverlässig, da die Lederhülle leicht beschädigt werden kann und dann ihre Wirkung verliert. Es ist auch schon vorgeschlagen worden, die empfindlichen Teile eines Höhenatemgerätes elektrisch zu beheizen.Atenu mask, in particular for high-altitude breathing apparatus The invention relates to a breathing mask designed especially for high altitude breathing apparatus. There are already Breathing masks of this type are known in which the exhalation valve is through a leather cover Is protected that the upper part of the breathing tube containing the exhalation valve loosely encloses. The warm exhaled air washes around the valve housing and protects it against Freeze. This arrangement is not reliable because the leather sheath is easily damaged and then loses its effect. It has also been suggested to electrically heat the sensitive parts of a high altitude breathing apparatus.

Die Erfindung besteht nun darin, .daß das Ausatemventil einer insbesondere für Höhenatemgeräte bestimmten Atemmaske in einem am Maskenkörper angebrachten oder mit diesem aus einem Stück bestehenden rohrförmigen Stutzen angeordnet ist, in dessen Wandung elektrische Heizdrähte eingebettet sind.The invention consists in .that the exhalation valve is a particular Respiratory mask intended for high-altitude breathing apparatus in a mask attached to or is arranged with this one-piece tubular connecting piece, in which Wall electrical heating wires are embedded.

Diese Anordnung des Ausatemventils bietet den Vorteil, daß das Ventil in dem Stutzen, der zugleich als Wärmemantel dient, gegen Beschädigungen geschützt liegt unddoch leicht ausgebaut werden kann, ohne daß die elektrische Beheizungsvorrichtung hierdurch beeinflußt wird.This arrangement of the exhalation valve has the advantage that the valve in the socket, which also serves as a thermal jacket, protected against damage and can easily be removed without the electrical heating device is influenced by this.

Auf der Zeichnung ist eine Ausführungsform der neuen Atemmaske dargestellt.The drawing shows an embodiment of the new breathing mask.

An dem Maskenkörper ,d ist der das Ausatemventil a aufnehmende Stutzen b angeordnet, in dessen Wandung die elektrischen Heizdrähte c eingebettet sind. Der Stutzen b besteht mit dem Maskenkörpend .aus einem Stück.The connector receiving the exhalation valve a is on the mask body, d b arranged, in the wall of which the electrical heating wires c are embedded. The socket b consists of one piece with the mask body.
