Abstract

A self-priming filter unit for filtering intravenous solutions. The filter unit is substantially rectangular in shape with an inlet at the bottom portion of the filter. The inner surface of the housing on the downstream side of the filter medium is grooved so as to cause air to flow to the outlet as the filter unit is being filled with liquid.
