Abstract
A blood dialyzer system which comprises a membrane dialyzer carried by dialysis solution delivery means and having blood and dialysis solution inlets and outlets. The membrane dialyzer is carried in a position whereby the blood inlet is vertically lower than the blood outlet, and the dialysis solution outlet is vertically lower than the dialysis solution inlet. Bubble trap means are provided in direct communication with the blood outlet and blood flow conduits, with the bubble trap means being preferably attached to and carried by the membrane dialyzer. The dialysis solution delivery means is adapted to permit intermittent reversal of the normal flow of dialysis solution through the membrane dialyzer to remove air bubbles trapped therein. Also, improved designs of integral bubble traps carried by dialyzers are shown.
