Six recently developed double pump tidal flow single needle systems have been assessed clinically and the magnitude of recirculation, efficiency of dialysis determined and compared with the classical system (Bellco BL 760). Results indicate that the problems of designing twin pump systems with instantaneous response, occlusive rollers capable of generating clinically acceptable blood flow rates has been largely overcome and such systems offer a high degree of patient acceptance, flexibility, safety and an efficiency of dialysis comparable with that obtained using two needle access.
