Line gravity-driven liquid filtration device - in that can be used for filtration of blood products or blood

摘要

(57)-in for biological fluids such as blood products or blood [summary] - line gravity filtration apparatus is disclosed. The device includes a (20, 21, 22) a series of channels formed in the downstream (3, 4, 5, 6) the filter element. The cross-sectional area is defined by the distance between the bottom and their (3,4,5,6) filtration element (20, 21, 22) this channel. The (20, 21, 22), an air channel (20, 21, 22) can be pushed downstream through the (91) outlet holes, minimizing the air trapped in the downstream side of the device whereby the channel It is designed to be, so as to form a flow path to the exit hole (91). For optimal performance, the exit aperture sum of the cross-sectional area channels or parallel, in cross-section area (21) channel to a single continuous lead exit hole of one to (91) and (22) (91) It should not exceed the cross-sectional area.
