A blood filter for use in filtering blood having side walls, a top, and a bottom joined to the side walls defining an axis with a filtration element surrounding at least a portion of the axis is disclosed. A delivery conduit delivers blood to the interior of the filter at an angle extending upwardly away from a plane which is perpendicular to the axis of the filter to form a vortex which is offset from the filter axis for release of entrapped air through an overlying top vent offset from the central axis, and an exit conduit connected to the interior of the filter element allows blood to flow from the filter element to an exit opening.

A filter for filtering blood under pressure in a circuit flowing partially outside of a human body comprising: a filter container formed by side walls, a bottom wall connected to said side walls, said bottom wall having an outlet conduit, and a top lid defining an axis, wherein said top lid has a centrally offset air vent allowing the release of air therefrom; wherein said centrally offset air vent is in generally overlying relationship to an area wherein a vortex is established by blood flowing into said filter for release of air directly toward said air vent; a filter element disposed between said side walls having a filter cap thereover; said filter cap having a rounded dome with a rounded peak extending above said rounded dome and wherein said filter cap and peak are within at least a portion of the axis of said filter, said filter cap further having a skirt extending over said filter with a chamfered edge; and a delivery conduit connected to the interior of said filter for delivery of blood to said filter having an axis at an angle extending upwardly away from a plane which is perpendicular to the axis of said filter so that the flow of blood is delivered upwardly toward the lid of said filter and over said filter cap.
