Abstract
An in-line liquid filtration device useable for filtration of blood, blood products or the like includes a housing having an inlet port, an outlet port, at least one filter element disposed in the housing between the inlet port and outlet port so as to filter liquid which flows into the filtration device via the inlet port. The filter element divides the housing into a first chamber and a second chamber. The device allows gases to vent the filtration device through the outlet port. The means may include a flow deflector within the first chamber and/or the second chamber. The means may also include a channel, preferably spiral, within either the first chamber and/or second chamber. The filtration device allows air therein to be purged downstream into either an air collecting bag or into the blood receiving bag without the manipulation of the height of the filtration device or the blood receiving bag.
