ABSTRACT:
Air or gas is prevented from entering into the exchange zone of an artificial organ such as an artificial kidney, dialyzer, or hemofilter. For this purpose a separating path is arranged in parallel with the artificial organ or with the exchange zone or other operative portion of the artificial organ between the liquid inflow and outflow conduits. This parallel path is provided with a high flow resistance for the liquid and with a low flow resistance for the air. Such differential flow resistance may, for example, be accomplished by apertures, gas permeable materials, and eddy chambers. The gas separating path is incorporated as an integral part of the artificial organ or as an integral part of the liquid inflow and outflow conduits. According to several embodiments, an enlargement is provided in the separating path or conduit in which the liquid may "rise and dwell" to enhance air separation before the liquid flows into the operative portion of the artificial organ.
