Abstract

L'invention concerne un ensemble masque facial comprenant un ou plusieurs évents d'écoulement d'air dans une section avant inférieure du masque ainsi qu'à l'intérieur de la zone nasale. L'évent d'écoulement d'air permet l'évacuation de la chaleur et du CO2 expirés. Les évents d'écoulement d'air peuvent être conçus pour diriger un écoulement d'air vers l'intérieur pour rentrer dans un filtre à air intérieur. Dans certains modes de réalisation, l'écoulement d'air rentre dans le filtre à air selon un angle oblique. Le filtre à air de capture de particules peut être remplaçable. Dans certains modes de réalisation, le filtre à air contient des éléments biocides. Dans certains modes de réalisation, la conception du filtre interne améliore la capture de l'H2O expirée qui active des ions argent dans le matériau du filtre pour créer un environnement biocide. Dans certains modes de réalisation, le masque facial possède deux zones d'encliquetage - une zone au-dessous du nez et une zone sous le menton qui peuvent loger une large gamme de sangles/tubes/joints toriques et qui peuvent être fixées derrière la tête par l'intermédiaire d'attaches ou divers dispositifs de blocage de cordon.
