A particulate blocking oxygen delivery mask includes a face piece constructed at least partially of a filtering material, a securing member such as a strap attached to the face piece, and an gas entry port disposed on the face piece. The gas entry port may include an optional one-way valve. The mask may be coupled to a continuous flow of oxygen or may be used as a partial or non- rebreathing mask. The mask permits the administration of high concentrations of oxygen to the patient while at the same time isolating the patient from any potentially contagious airborne particles in their surroundings. It also isolates any potentially contagious droplets or aerosolized particulate matter exhaled by a patient from entering the environment and potentially infecting others.

Masque de distribution d'oxygène bloquant les particules, comprenant un élément facial construit au moins partiellement en matériau filtrant, un élément de fixation tel qu'une sangle fixé à l'élément facial et un orifice d'entrée de gaz disposé sur l'élément facial. L'orifice d'entrée de gaz peut éventuellement comprendre un clapet anti-retour. Le masque peut être raccordé à un écoulement continu d'oxygène ou peut être utilisé comme masque partiel ou sans recirculation. Le masque permet l'administration de concentrations élevées d'oxygène au patient tout en isolant en même temps le patient de toutes particules aériennes potentiellement contagieuses l'environnant. Il isole également toutes gouttelettes ou matières particulaires en aérosol potentiellement contagieuses exhalées par un patient, qui pourraient être libérées dans l'environnement et éventuellement contaminer d'autres personnes.
