Title
(EN) ORO-NASAL VENTILATION FACE MASK
(FR) MASQUE FACIAL DE VENTILATION ORO-NASAL
Abstract
(EN)
An oro-nasal ventilation face mask worn by a patient includes a first chamber receiving airflow from an air source, a second chamber in fluid communication with the first chamber, a restrictive element positioned between the first chamber and the second chamber, and a headgear securing the first chamber and the second chamber to the patient. The second chamber includes a vent. Air flows between the first and second chambers through the restrictive element. When the first and second chamber are secured to the patient, the first chamber has a first air pressure, the second chamber has a second air pressure, and the first air pressure is greater than the second air pressure.
(FR)
L'invention concerne un masque facial de ventilation oro-nasal porté par un patient qui comprend une première chambre recevant un flux d'air provenant d'une source d'air, une seconde chambre en communication fluidique avec la première chambre, un élément de restriction positionné entre la première chambre et la seconde chambre, et un casque fixant la première chambre et la seconde chambre au patient. La seconde chambre comprend un évent. L'air s'écoule entre les première et seconde chambres par l'intermédiaire de l'élément de restriction. Lorsque les première et seconde chambres sont fixées au patient, la première chambre a une première pression d'air, la seconde chambre a une seconde pression d'air, et la première pression d'air est supérieure à la seconde pression d'air.
