초록

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.

청구항

Apparatus for providing air enriched with oxygen comprising: an array of selectively permeable membrane cells, said cells being adapted to permit oxygen to permeate therethrough at a greater rate than nitrogen; means for developing a flow of atmospheric air; means for directing at least a portion of said flow across said array to develop permeation into said cells, said directing means including a chamber structure around said array to define a flow path for air about the membranes; means for maintaining a partial vacuum within said cells to draw off the...
