Abstract
An in-line liquid filtration device (23) useable for filtration of blood includes a housing (1,2) having an inlet port (15), an outlet port (16), at least one filter element (5) disposed in the housing (1,2) between the inlet port (15) and outlet port (16) so as to filter liquid which flows into the filtration device (23) via an inlet port (15). The filter element (5) divides the housing into a first chamber (30) and a second chamber (29). Gases in the filtration device (23) are vented through the outlet port (16). The filtration device (23) includes a flow deflector (10) and/or a channel, preferably spiral, within the first chamber (30) and/or the second chamber (29).
