Abstract
(DE)

Die Erfindung betrifft eine Pumpvorrichtung, eine Vorrichtung zur Beatmung sowie ein Verfahren zur Bereitstellung eines Atemgases. Die erfindungsgemäße Lösung lehrt die Verwendung eines speziell geformten Läufers und einer korrespondierenden Pumpkammer, sodass ein etwa sinusförmiger Flow eines ausströmenden Fluids ermöglicht ist. Bei der Kombination von zwei erfindungsgemäßen Pumpkammern mit zueinander um 180° phasenversetzt angetriebenen Läufern ist so ein nahezu konstanter Flow an einem gemeinsamen Auslass realisierbar. Darüber hinaus ist das erfindungsgemäße System auf eine hohe Dynamik bei gleichzeitig relativ geringer Energieaufnahme ausgelegt. embedded image
