Title
(EN) INLINE MICROGRAVITY AIR TRAP DEVICE AND AN INTRAVENOUS ASSEMBLY INCORPORATING AN INLINE MICROGRAVITY AIR TRAP DEVICE
(FR) DISPOSITIF DE PIÈGE À AIR À MICROGRAVITÉ EN LIGNE ET ENSEMBLE INTRAVEINEUX INCORPORANT UN DISPOSITIF DE PIÈGE À AIR À MICROGRAVITÉ EN LIGNE
Abstract
(EN) An inline microgravity air trap device includes an elongate air trap chamber, the air trap chamber having a blind end, an opposite air outlet end containing a gas egress opening, a fluid inlet port connecting to a pressurized fluid supply, a fluid outlet port connecting the air trap chamber to a fluid delivery destination, a filter forming a tube having an interior, a first end at the blind end of the air trap chamber and a second end at the gas egress opening, and a structural insert in the interior of the tube, having a first insert end located at the blind end, and a second insert end located the air outlet end, where the chamber is formed to direct fluid from the pressurized fluid supply to accelerate centrifugally around the filter, forcing gas contained in the fluid to pass through the filter into the interior of the tube.
(FR) Un dispositif de piège à air à microgravité en ligne comprend une chambre de piège à air allongée, la chambre de piège à air ayant une extrémité fermée, une extrémité de sortie d'air opposée contenant une ouverture de sortie de gaz, un orifice d'entrée de fluide connecté à une alimentation en fluide sous pression, un orifice de sortie de fluide connectant la chambre de piège à air à une destination de distribution de fluide, un filtre formant un tube ayant un intérieur, une première extrémité à l'extrémité fermée de la chambre de piège à air et une seconde extrémité au niveau de l'ouverture de sortie de gaz, et un insert structural à l'intérieur du tube, ayant une première extrémité d'insert située au niveau de l'extrémité fermée, et une seconde extrémité d'insert située au niveau de l'extrémité de sortie d'air, la chambre étant formée pour diriger le fluide à partir de l'alimentation en fluide sous pression pour accélérer la centrifugation autour du filtre, forçant le gaz contenu dans le fluide à passer à travers le filtre à l'intérieur du tube.
