CA 2536951

A personal air purifier employs tapered reticulated foam semi-cylinders (10) sized to be closely received within a user's nostrils through slight expansion of the nostril. The semi-cylinders include a flat base (14) and a spherical shaped surface (12) at a distal end with flattened surfaces (30) circumferentially spaced about the semi-cylinder for enhanced fit within the nostril. The flat base of the two semi-cylinders is connected by an integral flexible band (16) which extends across the end of the septum of the user's nose to preclude over-insertion and aid in removal.

L'invention concerne un purificateur d'air personnel faisant appel à des demi-cylindres en mousse réticulée coniques (10) dimensionnés pour être étroitement reçus dans les narines d'un utilisateur par légère dilatation des narines. Les demi-cylindres comprennent une base plate (14) et une surface sphérique profilée (12) au niveau d'une extrémité distale présentant des surfaces aplaties (30) circonférentiellement espacées autour du demi-cylindre pour un ajustement amélioré dans les narines. La base plate des deux demi-cylindres est reliée par une bande flexible solidaire par construction (16) qui s'étend dans l'extrémité de la cloison du nez de l'utilisateur afin d'empêcher l'insertion trop profonde et de faciliter l'enlèvement.
