Abstract

L'invention concerne une canule nasale comprenant un corps de canule et un filtre. Le corps de canule comprend une paroi périphérique constituée d'un matériau imperméable à l'air et s'étendant entre une extrémité proximale et une extrémité distale, et définissant un passage d'air qui s'étend entre un orifice d'air proximal et un orifice d'air distal, le corps de canule étant de forme tronconique ou cylindrique et pouvant être inséré dans une narine d'un utilisateur, l'extrémité proximale étant positionnée à l'intérieur d'un vestibule nasal et l'extrémité distale étant positionnée sensiblement adjacente à une entrée de narine. Le filtre s'étend à l'intérieur du passage d'air et possède une paroi périphérique qui vient en butée contre la paroi périphérique du corps de canule, le filtre étant constitué d'un matériau perméable à l'air. L'invention concerne également une canule nasale comprenant un corps de canule incluant une paroi périphérique perméable à l'air.
