Abstract

Die Erfindung betrifft eine Aufnahme-Anordnung (100) und ein Verfahren zum Aufnehmen von Gas aus einem medizinischen Gerät (1). Die Aufnahme-Anordnung umfasst eine Zuführleitung (6), eine Abführleitung (8), eine Filtereinheit (4) mit einem Filter und mindestens einen Pufferspeicher. Die Zuführleitung (6) stellt eine Fluidverbindung zwischen dem medizinischen Gerät (1) und der Filtereinheit (4) her. Die Abführleitung (8) stellt eine Fluidverbindung zwischen der Filtereinheit (4) und einer Fluidaufnahme (7) her. Das Gas wird von dem medizinischen Gerät (1) ausgestoßen und durch die Zuführleitung (6) zu der Filtereinheit (4) und von dort durch die Abführleitung (8) zu der Fluidaufnahme (7) geleitet. Der Filter filtert mindestens einen Gas-Bestandteil aus dem Gas, das durch die Filtereinheit (4) geleitet wird, heraus. Der oder jeder Pufferspeicher vermag zeitweise Gas aufzunehmen und wieder abzugeben.
