Arterial blood filter with upwardly inclining delivery inlet conduit

摘要

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.
