摘要: A system for preparation of variable hemodialysate in which a controllable pump meters multiple fluid sources dialysate concentrates and water controlled proportion. The includes plurality cylinder piston assemblies linked together simultaneous operation. Individual valves connect the separate to individual be proportioned. position sensor provides signals indicative pistons throughout their stroke cycle, with control operates associated accord functions preselected proportioning inputs, so as volume metered by each pumps during stroke.
