Patent

CA 2582170

A biological fluid processing or fluid filtration system is provided having novel open and closed loop processing systems (44) wherein the gases transferred into and out of the system (55) during processing pass through a porous medium (67) in upstream and/or downstream gas inlet or outlet housings or vents (64, 71) in a manner which precludes the fluid being processed or filtered from ever contacting the housings or vents (64, 71). Each housing or vent (64, 71) is separated from the fluid by a column of gas in its respective transfer line (50, 54). The upstream gas inlet housing or vent (64) is in communication with the unfiltered biological fluid, and the downstream gas inlet housing or vent (71) is in communication with the filtered biological fluid.

On propose un système de traitement des fluides biologiques ou de filtration des fluides comportant de nouveaux systèmes de traitement en boucle ouverte et en boucle fermée (44) dans lesquels les gaz transférés dans le système (55) ou hors du système (55) pendant le traitement passent à travers un milieu poreux (67) dans les viroles ou les évents (64, 71) d'admission ou d'évacuation des gaz en amont et/ou en aval, de telle manière que les fluides traités ou filtrés ne viennent jamais en contact avec les viroles ou les évents (64, 71). Chaque virole ou évent (64, 71) est séparé du fluide par une colonne de gaz dans sa conduite de transfert (50, 54). La virole ou l'évent (64) d'admission des gaz en amont communique avec le fluide biologique non filtré, et la virole ou l'évent d'admission des gaz en aval (71) communique avec le fluide biologique filtré.
