ABSTRACT:
An intravenous filter device comprises a filter housing having a front side, a back side, a first end, a second end, an inlet and an outlet, the housing containing a hydrophilic filtration media and defining a flow path such that intravenous fluid entering the housing through the inlet passes through the filtration media before passing out of the housing through the outlet. Inlet and outlet tubing connectors, both preferably attached to the front side of the filter housing, form, respectively, the housing inlet and outlet. In the preferred embodiment the connectors are raised above the front side or the housing such that tubing connected to the connectors does not intersect the front side of the housing. At least one vent hole in the housing provides a passageway for gas to escape from the housing, the vent hole being preferably open to the front side of the housing. A hydrophobic membrane is positioned between the vent hole and the flow path at a position along the flow path between the inlet and the hydrophilic filtration media. In a preferred embodiment, a tubing clip is provided to help orient the filter to make it self priming and prevent I.V. set tubing from kinking,
