Title (EN) RESPIRATORY VALVE FACE MASK STRUCTURE
(FR) MASQUE RESPIRATOIRE A VALVE
Abstract: front page image
(EN)The respiratory valve face mask (10) herein relates to a structure for use in restoring respiration by providing for a subject of respiratory failure or cardiac arrest a supply of pressurized oxygen enriched air (73) and which permits in the alternative the free passage of ambient air to the subject under atmospheric pressure. The mask (10) comprising the invention herein has a plurality of chin grooves (15) to provide a general face fit for various sizes or lengths of faces with a perimeter (12) overlying the air passages of a face together with appropriate strap members (20, 21) to secure the same about the head of a person and projecting from the inner surface of the mask (10) in a particularly designed air sealing rib (16) encircling the nose and mouth and carried in the mask (10) is a valve structure (35, 63) which permits the free passage of ambient air to the person atmospheric pressure and into which the input of oxygen (84) or oxygen enriched air (84, 73) under appropriate pressure acts upon a piston (52) to close the valve (41) to ambient air, and further, in connection therewith, is pressure relief (41) to the atmosphere in the event of an excessive build up of the pressure of oxygen or oxygen enriched air within the mask.
(FR)Le masque respiratoire a valve (10) se rapporte a un ensemble destine a retablir la respiration qui fournit a un sujet en etat d"arret respiratoire ou d"arret cardiaque de l"air enrichi en oxygene pressurise (73) et qui permet en alternative le passage de l"air ambiant sous pression atmospherique vers le sujet. Le masque (10) selon l"invention comporte une pluralite de rainures de menton (15) permettant d"ajuster le masque pour differentes dimensions des visages, avec un perimetre (12) se superposant aux passages d"air d"un visage ainsi que des courroies (20, 21) permettant de fixer le masque sur la tete d"une personne. Une nervure d"etancheite (16) faisant saillie depuis la surface interne du masque (10) et presentant un profil particulier, entoure le nez et la bouche. Une valve (35, 63) permet le libre passage de l"air ambiant sous pression atmospherique dans laquelle l"alimentation en oxygene (84) ou en air enrichi en oxygene (84, 73) sous la pression appropriee agit sur un piston (52), obturant ainsi la valve (41) et assurant la detente (41) jusqu"a la pression atmospherique dans le cas ou la pression d"oxygene ou d"air enrichi en oxygene serait excessive.
