Title
(DE) METHODE ZUR ULTRASCHALL-ENTGASUNG VON FLÜSSIGKEITEN FÜR DIE DIALYSE
(EN) METHOD FOR THE ULTRASONIC DEGASSING OF LIQUIDS FOR DIALYSIS
(FR) PROCÉDÉ DE DÉGAZAGE PAR ULTRASONS DE LIQUIDES DE DIALYSE
Abstract
(DE)
Die Erfindung umfasst eine Vorrichtung zur Entgasung von Flüssigkeiten, insbesondere Flüssigkeiten, die in der Dialyse Verwendung finden. Zu entgasende Flüssigkeiten werden in einer Entgasungseinheit durch Ultraschall behandelt und durch einen Hohlkanal der Ultraschallsonotrode aus der Entgasungseinheit für die weitere Verwendung ausgeleitet.
(EN)
The invention comprises a device for degassing liquids, in particular liquids that are used for dialysis. Liquids to be degassed are treated in a degassing unit with ultrasound and discharged from the degassing unit through a hollow channel of the ultrasonic sonotrode. u
(FR)
L'invention concerne un dispositif pour dégazer des liquides, en particulier des liquides utilisés en dialyse. Les liquides à dégazer sont traités par ultrasons dans une unité de dégazage et sont dirigés à l'extérieur de l'unité de dégazage par un canal creux de la sonotrode à ultrasons en vue de leur utilisation.
