Abstract

In order to prevent anaesthetic gases from escaping into the surrounding operating theatre with the anaesthetic mask in place, it is proposed that the mask comprise an inner mask (1) and an outer mask (2), there being a slit-shaped suction opening (3) between the inner (1) and outer (2) masks. The gap between the inner (1) and outer (2) masks is provided with a central suction (4).

Description

Beschreibung und Erläuterung zur PatentanmeldungDescription and explanation of the patent application

Narkosemaske#L, Es ist bekannt, daß bei dem Aufsetzen der Narkosemaske zwangsläufig Narkosegase auch in den OP-Raum einfließen.Anesthetic mask # L, It is known that when the anesthetic mask is put on Inevitably, anesthetic gases also flow into the operating room.

Die Negativ-Einflüsse sind vielfach sehr belastend für das Personal und bewirken vielfach einen Konzentrationsabbau.The negative influences are often very stressful for the staff and often cause a decrease in concentration.

Erfindungsgemäß wird daher vorgeschlagen, die OP-Maske so auszubilden, daß sie ein Austreten von Narkosegasen verhindert und zwar in der Form, daß eine zweite Obermaske mit Randabsaugung so versehen ist, daß die aus dem Innenbereich austretenden Narkosegase durch die Randabsaugung erfaßt werden und unschädlich abgesaugt werden.According to the invention, it is therefore proposed to design the surgical mask in such a way that that it prevents leakage of anesthetic gases in the form that a second upper mask is provided with edge suction so that from the inside escaping anesthetic gases are captured by the edge suction and sucked off harmlessly will.

In der beiliegenden Zeichnung ist dargestellt: mit (1) die Innenmaske mit (2) die Außenmaske mit (3) der Absaugschlitz unten mit (4) die Zentralabsaugung zur Abführung der Narkosegase, die in ein Chemisorptionspaket eingeführt werden können oder auch nach draußen abgeführt werden können.The attached drawing shows: with (1) the inner mask with (2) the outer mask with (3) the suction slot at the bottom with (4) the central suction for the removal of the anesthetic gases, which are introduced into a chemisorption package can or can also be discharged outside.
