An upper cap sealed to the top of the lower body portion includes a blood inlet tube into which a conical dispersion plate is projected so as to decrease the rate of flow of the blood. The rate of flow further decreases as it enters a debubbling chamber in the cap. A top wall of the cap defines a sloped and arched channel around the inlet tube adapted to direct released gas toward a vent tube at the uppermost extent of the sloped top wall.Field of SearchWITH GAS SEPARATORWithin flow line or flow line connected close casing Vented Axially aligned inlet and outlet Gasket within casing or spaced removable end members Prefilt flow distributor or diverter With central pervious tubular receiver Vented Filter or series thereof for liquid entering or leaving container | |
