Abstract
A device, which may be used in a dialysis system, is disclosed for separating low density material such as gas bubbles from a liquid by swirling the liquid, to cause the bubbles to migrate toward the center of the swirling liquid. A liquid storage chamber having side walls of generally circular cross-section of the longitudinal axis is provided. A port is provided for removing the bubbles or the like, positioned adjacent the longitudinal axis of the chamber. A liqud inlet passes into the chamber in such a position as to pass liquid into the chamber circumferentially about the side walls, to provide swirling of liquid passing into the chamber. In accordance with this invention, outlet means and pump means are provided for removing bubble-free liquid from the chamber at a point spaced from the inlet but adjacent the side wall. A first conduit conveys a portion of the bubble-free liquid so removed to a desired site of use, while a second conduit conveys the balance of the bubble-free liquid so removed back to the liquid inlet for reentry into the chamber, to enhance the swirling action of fluid in the chamber.
