ABSTRACT:
An air eliminating filter for use in filtering intravenous or other liquids including an elongate hollow tubular member provided with inlet means at one end and having at least two window openings spaced longitudinally thereon, a hydrophilic filter element capable of passing liquid therethrough when the filter element has been wetted with liquid while simultaneously blocking air interposed in one of the window openings, at least one hydrophobic filter element capable of repelling liquid and passing air therethrough positioned in the other of the window openings and communicating with the ambient air and manifold means including outlet means to discharge liquid therefrom mounted on the tubular member communicating with the hydrophilic filter whereby the hydrophilic filter is wetted with liquid passed into the tubular member through the inlet means to permit the hydrophilic filter to pass liquid therethrough while simultaneously blocking air. The liquid passing through the hydrophilic filter element is collected in the manifold means for discharge through the outlet means while air in the tubular member is discharged through the hydrophobic filter.
