PARTICULATE BLOCKING OXYGEN DELIVERY MASK

摘要

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.
