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.
(EN) The invention relates to a pump device, a respiratory device and a method for providing a respiratory gas. The solution according to the invention involves the use of a specially formed rotor and a corresponding pump chamber, such that an approximately sinusoidal flow of an out-flowing fluid is possible. With the combination of two pump chambers according to the invention with rotors driven in a 180° phase-shifted manner to one another, an almost constant flow can be created at a common outlet. In addition, the system according to the invention is designed to be highly dynamic with simultaneously relatively low energy consumption.
(FR) L'invention concerne un dispositif de pompe, un dispositif respiratoire et un procédé permettant de fournir un gaz respiratoire. La solution selon l'invention implique l'utilisation d'un rotor spécialement formé et d'une chambre de pompe correspondante, de telle sorte qu'un écoulement approximativement sinusoïdal d'un fluide en écoulement est possible. Grâce à la combinaison de deux chambres de pompe selon l'invention avec des rotors entraînés de manière décalée en phase de 180° l'un par rapport à l'autre, un écoulement presque constant peut être créé au niveau d'une sortie commune. De plus, le système selon l'invention est conçu pour être hautement dynamique avec une consommation d'énergie simultanément relativement faible.
