Abstract

The filter has a pair of short, tubular filter elements of which one is pushed up each nostril. Each element has perforated ends and contains a substance such as silica gel to retain impurities carried by air passing through the element. The two elements are connected by a short cord, pref. elastic, on the outside of the nose. The cord prevents the elements being pushed too far up the nostrils and serves for pulling out the elements.

Description

La présente invention concerne la protection des personnes contre la pollution atmosphérique de l'air respire. The present invention relates to the protection of people against atmospheric pollution of the air breathes.

Les dispositifs utilisés se sont révélés d'un usage peu commode (masques appliqués extérieurement sur le visage), peu efficace et/ou gênants (boules de coton dans les narines). The devices used have been found to be inconvenient to use (masks applied externally to the face), ineffective and / or bothersome (cotton balls in the nostrils).

L'invention remédie à ces inconvénients et a pour but un dispositif nasal de protection contre la pollution atmosphérique, caractérisé en ce qu'il comprend deux tubes, de dimension appropriée, pour être introduits dans le nez par la narine et logé dans le vestibule, un produit disposé dans le tube pour retenir les impuretés, un cordonnet réunissant la base des deux tubes, de façon à limiter leur enfoncement dans la cavité nasale, et faciliter leur extraction. Chaque tube est fermé à chaque extrémité par un opercule perméable à l'air après avoir été rempli de gel de silice ou autres cristaux ou autre fibres végétales ou minérales. Pour que tout l'air respiré passe obligatoirement dans le tube, ce dernier est muni extérieurement d'une ou plusieurs collerettes souples à lamelles prenant appui sur les muqueuses des parois nasales.Ces collerettes assurent à la fois ltétanchéi- té et l'ancrage du tube dans le vestibule du nez. The invention overcomes these drawbacks and aims at a nasal device for protection against atmospheric pollution, characterized in that it comprises two tubes, of appropriate size, to be introduced into the nose through the nostril and housed in the vestibule, a product placed in the tube to retain impurities, a cord joining the base of the two tubes, so as to limit their penetration into the nasal cavity, and facilitate their extraction. Each tube is closed at each end by an air-permeable cover after having been filled with silica gel or other crystals or other vegetable or mineral fibers. So that all the air breathed in necessarily passes through the tube, the latter is provided externally with one or more flexible flaps with lamellae resting on the mucous membranes of the nasal walls. These flanges ensure both the sealing and the anchoring of the tube in the vestibule of the nose.

Pour mieux faire comprendre l'invention il est donné ci-après un exemple de réalisation en référence aux dessins annexés. To better understand the invention, an exemplary embodiment is given below with reference to the accompanying drawings.

Fig. 1 est une coupe schématique montrant l'empla- cement d'un tube dans une narine,
Fig. 2 est une vue en perspective de l'ensemble du filtre,
Fig. 3 est une vue en coupe d'un tube filtre,
Fig. 4 est une vue en perspective d'une variante.Fig. 1 is a diagrammatic section showing the location of a tube in a nostril,
Fig. 2 is a perspective view of the entire filter,
Fig. 3 is a sectional view of a filter tube,
Fig. 4 is a perspective view of a variant.

Les tubes peuvent être fabriqués en toute matière appropriée, notamment a l'aide d'une feuille cellulosique ou extrudé ou injecté en une matière plastique souple, de dimentions telles qu'un tube 1 puisse être introduit dans une narine 4. Les tubes 1-2 sont réunis par un petit cordonnet 3 fixé sur eux, de préférence transparent, élastique ou non, ou couleur chair, de telle manière que lors de leur introduction dans les narines 4, on ne puisse pas les enfoncer trop profon dément dans la fosse hnsale 5. Après mise en place, le cordonnet 5 reste extérieur et passe sos la cloison du nez. The tubes can be made of any suitable material, in particular using a cellulosic sheet or extruded or injected into a flexible plastic material, in dimensions such that a tube 1 can be introduced into one nostril 4. The tubes 1- 2 are joined by a small cord 3 fixed on them, preferably transparent, elastic or not, or flesh-colored, so that when they are introduced into the nostrils 4, they cannot be pushed too deeply into the fossa 5. After installation, the cord 5 remains outside and passes under the septum of the nose.

l'out retirer les tubes 1-2 il suffit de tirer sur le cordonnet 3. the out remove the tubes 1-2 just pull on the cord 3.

Chaque tube est rempli par un gel de silice 6 fermé par des tamis 7 et 8. Each tube is filled with silica gel 6 closed by sieves 7 and 8.

Les tubes 9, 10 peuvent être coniques, ovoïdes, courbes et fermés à la base par un opercule Il ou 12 perméable a l'air au milieu duquel est fixé le cordonnet 13. The tubes 9, 10 can be conical, ovoid, curved and closed at the base by an air-permeable cap 11 or 12 in the middle of which the cord 13 is fixed.

Les tubes peuvent être légèrement compressibles et/ou élastiques pour bien s'appliquer contre la muqueuse du nez et assurer une bonne étanché--té. On peut aussi munir chaque tube de petites collerettes 14, 15 très souples (et éventuellement ondulées) qui assurent non seulement l'étan- chéité, mais également un véritable ancrage. Ainsi les tubes ne peuvent pas se déplacer de façon intempestive. The tubes can be slightly compressible and / or elastic to apply well against the mucous membrane of the nose and ensure a good seal. It is also possible to provide each tube with small flanges 14, 15 which are very flexible (and possibly wavy) which not only ensure the watertightness, but also a real anchoring. Thus the tubes cannot move unexpectedly.

Le dispositif selon l'invention filtre l'air pollué et le débarrasse de la majeure partie des impuretés (goudron) sans aucun ralentissement de la mécanique ventilatoire, ne provoque ni irruption, ni nasonnement. Dans le cas de substance minérale (gel de silice) le filtre a aussi des propriétés anallergi#antes.  The device according to the invention filters the polluted air and rids it of most of the impurities (tar) without any slowing down of the ventilatory mechanics, causes neither irruption nor nasalization. In the case of mineral substance (silica gel) the filter also has hypoallergenic properties.
