Abstract
A mobile, personal oxygen enricher includes means for producing a flow of atmospheric air, heating the air to a pre-selected temperature, and directing the air over an array of selectively permeable membrane cells which permit the permeation of oxygen at a greater rate than nitrogen. Vacuum means maintain the cells at a partial vacuum and draw off oxygen enriched gas. The enriched gas passes through a scrubber to remove pollutants and is directed to a patient for inhalation.
