Patent

CA 2451098

An adjustable mask provides a unique configuration, whereby one hand may be used to both doff the respirator and to securely don the mask. In one embodiment, such configuration is facilitated by a reel attached to one or cord attached at a second end to a harness designed to engage a portion of the head. Rotation of the reel in one direction causes the one or more cords to loosen.

L'invention concerne un masque réglable de configuration unique, une seule main suffisant pour à la fois enlever l'appareil respiratoire et placer fermement le masque sur le visage. Dans un mode de réalisation, cette configuration comporte une bobine fixée à un ou plusieurs cordons dont la deuxième extrémité est attachée à un harnais conçu pour être en prise avec une partie de la tête. La rotation de la bobine dans une direction resserre le ou les cordons et sa rotation dans la direction opposée les relâche.
