Abstract
A high capacity gravity feed filter for filtering blood and blood products or the like includes a body having an inlet port, an outlet port, two filter wells, at least one filter element disposed in each of said filter wells, between the inlet port and outlet port so as to filter liquid which flows into the filtration device via the inlet port. The filter elements divide each of said filter wells 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 through slot located at the top of each of said second chambers. The filtration device allows air therein to be purged downstream into a receiving blood bag without the manipulation of the height of the filtration device or the receiving blood bag.
