Abstract
A port spike for medical fluid containers, such as infusate bags, for example, provides two ports to permit recirculation of fluids within the container. The recirculating flow allows bubbles to settle out which can't happen effectively if the flow is sucked out immediately after entering the container. The spike provides two openings inside the container which prevent such short-circuit flow by ensuring that fluid entering the container is not greatly affected by the suction zone of the flow leaving the container.
