<p>A device for the enrichment of respiratory air with oxygen, includes a supply gas to be enriched which is supplied to at least one concentrator and from there to a product gas line in an adjustable concentration of enrichment. The required concentration of enrichment is adjusted speedily and without loss to the changing amount which is used, and as high a concentration of enrichment as possible at an adjustable and low throughput of the concentrator is achieved by use of a partial flow of the supply gas through a throughput-adjustable bypass line. The bypass line bypasses the product gas line and at least one concentrator.</p> |
