Abstract

La présente demande de brevet d'invention concerne essentiellement un masque de protection respiratoire avec dispositif conjugué de filtrage moléculaire de l'air inspiré au moyen d'un mécanisme d'aspiration et de ventilation électrique, dont la fonction consiste à empêcher l'utilisateur d'inspirer des contaminants aérobies ou d'être exposé à une contamination oculaire; l'invention assure une protection de la santé personnelle de l'utilisateur et prévient contre une contamination par dissémination; l'air ambiant est aspiré par un ventilateur vers l'intérieur du boîtier d'accouplement et la pression exercée par l'aspiration amène l'air à traverser l'élément filtrant existant à l'intérieur du boîtier avant d'être acheminé par des canaux de dispersion vers le visage de l'utilisateur, cet air étant exempt de particules virales ou bactériologiques et de tout autre contaminant.
