Abstract
An air removal device for an intravenous fluid system includes a housing with an inlet for fluid communication with a fluid source, a fluid outlet for fluid communication with a blood vessel of a patient, and an air outlet. The air removal device further includes a disrupting element disposed within the housing in a flow path between the inlet and the fluid outlet, and an air chamber in fluid communication with the air outlet. The disrupting element includes a protrusion extending across the flow path. The flow path includes a first cross-sectional flow area at the inlet, and a second cross-sectional flow area at the protrusion. The second cross-sectional flow area is smaller than the first cross-sectional flow area.
