Title (EN) NOSE-WORN AIR FILTER
(FR) FILTRE A AIR SE PORTANT SUR LE NEZ
Abstract:
(EN) A device which attaches to the nose and filters the air a person breathes through the nostrils on the nose. The filter element (2) of the device covers the nostrils and base of the nose. Thus, the remainder of the face is uncovered. The device includes the filter element and an adhesive strip (1) which includes two substantially triangular portions (3a, 3b) designed to adhere to the sides of the nose and hold the filter in place. The adhesive strip is such that it securely holds the filter over the nostrils when the adhesive strip is properly placed on the sides of the nose. The filter element can be constructed of such materials as cotton, wool, polyester, or carbon. The filter element can include specially designed inserts (32) which are dome shaped or ellipsoidal shaped and which fit in or against the nostrils.
(FR) Un dispositif s'attache sur le nez et filtre l'air qu'une personne respire à travers les narines. L'élément filtrant (2) du dispositif recouvre les narines et la base du nez. Ainsi, le reste du visage est découvert. Le dispositif comporte l'élément filtrant et une bande adhésive (1) qui comporte deux parties sensiblement triangulaires (3a, 3b) destinées à adhérer sur les ailes du nez et à maintenir le filtre en place. La bande adhésive est telle qu'elle maintient solidement le filtre sur les narines lorqu'elle est correctement placée sur les ailes du nez. L'élément filtrant peut être constitué de matériaux tels que du coton, de la laine, du polyester ou du carbone. L'élément filtrant peut renfermer des insertions (32) spécialement conçues qui sont en forme de dôme ou d'ellipse et qui s'adaptent dans ou contre les narines.
