Title
(DE) VENÖSE BLASENFALLE
(EN) VENOUS BUBBLE TRAP
(FR) DISPOSITIF DE PIEGEAGE DE BULLES D'AIR VEINEUX
Abstract
(DE)
Bei einer venösen Blasenfalle (1) mit einem Gehäuse (2), dem über einen Flüssigkeitseinlass (8) im Wesentlichen tangential Flüssigkeit, insbesondere Blut, zuführbar ist und aus dem über einen Flüssigkeitsauslass (10) Flüssigkeit abführbar ist, und mit einer im Innenraum des Gehäuses (2) angeordneten Filtereinrichtung (3) unterteilt die Filtereinrichtung (3) den Gehäuseinnenraum in einen Vorfilter- und einen Nachfilterbereich (5, 6), wobei der Nachfilterbereich (6) den Vorfilterbereich (5) zumindest abschnittsweise umgibt. Dadurch wird Luft zuverlässig aus der Flüssigkeit entfernt.
(EN)
In a venous bubble trap (1) with a housing (2) to which liquid, in particular blood, can be delivered more or less tangentially via a liquid inlet (8) and from which liquid can be removed via a liquid outlet (10), and with a filter device (3) arranged in the interior of the housing (2), the filter device (3) divides the housing interior into a pre-filter area and a post-filter area (5, 6), the post-filter area (6) at least partially enclosing the pre-filter area (5). In this way, air is reliably removed from the liquid.
(FR)
L'invention concerne un dispositif de piégeage de bulles d'air (1) veineux comprenant un boîtier (2) auquel un liquide, notamment du sang, est cédé de manière sensiblement tangentielle par l'intermédiaire d'un orifice d'entrée de liquide (8) et duquel du liquide est prélevé par l'intermédiaire d'un orifice de sortie de liquide (10), ainsi qu'un dispositif filtrant (3) logé dans le boîtier (2). Ce dispositif filtrant (3) divise l'intérieur du boîtier en une zone de préfiltrage et une zone de post-filtrage (5, 6). La zone de post-filtrage (6) entoure au moins partiellement la zone de préfiltrage (5). Cela permet d'éliminer de manière fiable l'air du liquide.
