ABSTRACT:
An air removal device removes air from blood flowing in a perfusion system. A generally cylindrical chamber has a liquid flow region at a lower end thereof and has a gas collection region at an upper end thereof. An arcuate manifold provides an arcuate flow path outside of the chamber having an upstream end and a downstream end. A slit aperture is provided between the arcuate manifold and the chamber along at least a substantial portion of the arcuate manifold. A mixture of gas and liquid introduced into the arcuate flow path at the upstream end flows through the slit aperture to create a spiral flow within the chamber causing the gas to move toward a central axis of the chamber and into the gas collection region.
