Description

Die Erfindung betrifft einen-Nasenfilter, der aus zwei in die Nasenlöcher einfuhrbaren, durch einen federnden Steg miteinander verbundenen und eine Filtermasse aufweisenden Röhrchen besteht.The invention relates to a nasal filter, which consists of two in the nostrils insertable, interconnected by a resilient web and a filter mass having tubes.

Das Neue wird darin gesehen, daß die Röhrchen gekrümmt sind und sich so der Form der Nasenöffnungen anpassen.The novelty is seen in the fact that the tubes are curved and become so adapt to the shape of the nostrils.

In eine ringförmige Nut im vorderen Teil eines jeden Röhrchens kann ein flacher Filter eingesetzt sein, der zweckmäßig klappenförmig ausgebildet ist und dessen Klappe sich beim Ausatmen zur Erleichterung des Ausstoßens der Luft öffnet.In an annular groove in the front part of each tube a flat filter can be used, which is expediently designed in the shape of a flap and the flap of which opens on exhalation to facilitate the expulsion of air.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt.The drawing shows an embodiment of the subject matter of the invention shown.

Abb. r ist die Ansicht eines Nasenfilters; Abb. 2 ist die Seitenansicht einer Nase mit eingesetztem Filter; Abb. 3 stellt einen Längsschnitt durch ein Röhrchen dar, und Abb. 4 stellt einen Querschnitt durch eine in die Röhrchen einzusetzende Filterscheibe dar.Fig. R is a view of a nasal filter; Fig. 2 is the side view a nose with an inserted filter; Fig. 3 shows a longitudinal section through a tube and Fig. 4 shows a cross-section through one to be inserted into the tube Filter disc.

Wie aus Abb. r ersichtlich ist, besteht der Nasenfilter aus zwei konisch zulaufenden, gebogenen Röhrchen a, 2, die durch einen federnden und mit Greifnocken 4, 5 versehenen Steg 3 miteinander verbunden sind. Die Innenwand eines jeden Röhrchens weist am vorderen Ende eine Nut 8 zur Aufnahme von Filtereinsätzen 6; 7 auf. Die Filtereinsätze sind auswechselbar und klappenförmig ausgebildet; beim Ausatmen (Abb. 4, Richtung A) öffnen sie sich, beim Einatmen (Richtung B) schließen sie sich. Als Filtermasse dient eine dünne Lage Watte mit einem feinmaschigen Sieb; der Watte kann zur Bindung von schlechten Gerüchen Kohle beigegeben sein.As can be seen from Fig. R, the nasal filter consists of two conical tapered, curved tubes a, 2, which are supported by a resilient and gripping cam 4, 5 provided web 3 are connected to one another. The inner wall of each tube has at the front end a groove 8 for receiving filter inserts 6; 7 on. the Filter inserts are replaceable and designed in the form of flaps; on exhalation (Fig. 4, direction A) they open, when inhaling (direction B) they close. as Filter mass is a thin layer of cotton wool with a fine-mesh sieve; the cotton wool coal can be added to bind bad smells.

Die Röhrchen bestehen zweckmäßig aus geruchloser Acethylcellulose oder aus geruchfreiem, der Gesichtsfarbe angepaßtem Gummi.The tubes are expediently made of odorless acetyl cellulose or made of odor-free rubber that is adapted to the color of the face.

Der Nasenfilter nach der Erfindung kann nicht nur als Atemschutzvorrichtung beim Aufenthalt in staubhaltigerLuft, sondern auch .als Medikamententräger ohne Sichtbehinderung von Gesunden und Kranken getragen werden.The nasal filter according to the invention can not only be used as a respiratory protection device when staying in dusty air, but also as a medicament carrier without Visibility impairment can be borne by the healthy and the sick.
