Title
(EN) ARTERIAL AIR CAPTURE CHAMBER
(FR) CHAMBRE DE CAPTURE DE L'AIR ARTÉRIEL
Abstract
(EN)
An arterial air capture chamber (101) is used in dialysis. The arterial air capture chamber (101) includes an upwardly extending fluid inlet (102) terminating in a fluid inlet port (105) positioned at about a 90° turn relative to a fluid flow of a fluid inlet tube (107). The arterial air capture chamber (101) includes a draw tube (104) with an opposedly positioned beveled opening (306) at about 180° relative to the fluid inlet port (105). The arterial air capture chamber (101) provides improved fluid dynamics, reducing both stagnant flow and turbulence. The arterial air capture chamber (101) also provides for bidirectional flow of fluid through the arterial air capture chamber (101).

Une chambre de capture de l'air artériel (101) est utilisée en dialyse. La chambre de capture d'air artériel (101) comprend une entrée de fluide s'étendant vers le haut (102) se terminant dans un orifice d'entrée de fluide (105) positionné à environ un tour de 90 ° par rapport à un écoulement de fluide d'un tube d'entrée de fluide (107). La chambre de capture de l'air artériel (101) comprend un tube d'aspiration (104) avec une ouverture biseautée positionnée de manière opposée (306) à environ 180° par rapport à l'orifice d'entrée de fluide (105). La chambre de capture de l'air artériel (101) améliore la dynamique des fluides, réduisant à la fois l'écoulement stagnant et la turbulence. La chambre de capture de l'air artériel (101) fournit également un écoulement bidirectionnel de fluide à travers la chambre de capture de l'air artériel (101).
