Abstract

Dispositif de mesure du débit de fuite d'au moins un élément de masque de protection respiratoire, le masque de protection respiratoire comportant au moins un orifice de communication entre l'intérieur du masque, par l'intermédiaire d'une entrée, et l'extérieur du masque, par l'intermédiaire d'une sortie, l'orifice de communication ayant une position ouverte dans laquelle un fluide peut traverser l'orifice entre l'entrée et la sortie et une position fermée dans laquelle un fluide ne peut pas traverser l'orifice, le dispositif de mesure comprenant : - un moyen de génération d'un différentiel de pression entre l'intérieur et l'extérieur du masque, - un moyen de contrôle du moyen de génération d'un différentiel de pression entre l'intérieur et l'extérieur du masque, - un moyen de mesure apte à mesurer le débit de fuite de l'orifice de communication, en position fermée, au niveau de l'entrée, respectivement de la sortie, - un moyen de fixation du moyen de génération d'un différentiel de pression entre l'intérieur et l'extérieur du masque, au voisinage de l'orifice de communication.
