Beschreibung
Zusammenfassung:	An air or oxygen flow supply system between a supply source and nasal prongs applicable to a patient, comprising a succession of flow ducts having different flow areas, there being junctions between successive of the ducts, the flow areas defined by A1, A2---An where n>2, the flow areas decreasing at the junctions, in the direction of the flow. La présente invention concerne un système d'alimentation en flux d'air et d'oxygène entre une source d'alimentation et des embouts nasaux pouvant être appliqués sur un patient, ledit système comprenant une succession de conduites d'écoulement ayant différentes zones de flux, des jonctions se trouvant entre les conduites successives, les zones de flux étant définies par A1, A2---An où n > 2, les zones de flux diminuant au niveau des jonctions, dans la direction du flux.
