An apparatus for enriching respiratory gas with oxygen, wherein the entire enriched respiratory gas can be taken from an absorber bed and the enrichment concentration is adjustable by action on the total flow through the adsorber and the portion of the total flow in excess of the consumer flow is removable via an outflow, is improved so that adjustment of enrichment concentration and consumer flow independently of each other is possible and the enrichment concentration is maintained also at fluctuating consumer flow. To this end a control circuit for the...
An apparatus for enriching respiratory gas for a patient with oxygen comprising: adsorber bed oxygen enrichment means for producing a total enriched respiratory gas flow in excess of the flow to be delivered to the patient having an inlet for drawing in air and an outlet for said flow of enriched respiratory gas; control circuit means having an outlet and having an inlet connected to said adsorber bed means outlet, said control circuit means for independently controlling the rate of flow of air into said adsorber bed means and the rate of flow of enriche...
