Patent ID: 8801922

Claim:
A medical system, comprising: a filtration system capable of filtering a water stream; a water purification system capable of purifying said water stream in a non-batch process, comprising a microfluidic heat exchange system comprising a dwell chamber, wherein the water stream is maintained in the dwell chamber at a pasteurization temperature for a period of time effective to pasteurize the water stream; a mixing system capable of producing a stream of dialysate from mixing one or more dialysate components with the water stream in a non-batch process; and a dialyzer system, comprising a microfluidic or flow field dialyzer capable of being fluidly coupled to the stream of dialysate and a blood stream, the dialyzer having a membrane separating the stream of dialysate from the blood stream, the membrane facilitating dialysis of the blood stream; a plurality of pumps capable of pumping the stream of dialysate across the dialyzer; and a controller operatively coupled to the plurality of pumps, the controller capable of controlling a flow rate of the dialysate stream through one or more of the plurality of pumps so as to perform one or both of the processes of ultrafiltration and hemodiafiltration on the blood stream while the blood stream is undergoing dialysis.
