  • Publication number: 20110272337
    Abstract: A compact portable dual mode hemodialysis machine system is provided. The system includes a sorbent dialysis module with a sorbent cartridge that purifies a dialysate fluid that flows therethrough, where the sorbent dialysis module returns the purified dialysate fluid from the sorbent cartridge to an inlet of a dialyzer. The system also includes a single-pass dialysis module with an acetate pump, a bicarbonate pump and a mixing chamber, where the acetate and bicarbonate pumps flow acetate and bicarbonate mixtures, respectively, into the mixing chamber. The single-pass dialysis module receives a desired amount of water from a reverse osmosis device, the single-pass dialysis module operated to direct used dialysate from the dialyzer to a drain.

  • Publication number: 20110272352
    Abstract: A sorbent hemodialysis system includes a dialyzer configured to receive a flow of clean dialysate from a reservoir and to output an unclean dialysate flow. The system also includes a sorbent component having a urease section and a sorbent section through which the unclean dialysate flow from the dialyzer passes, wherein the sorbent component removes urea from the dialysate. The system further comprises a membrane electrolyzer that receives at least a portion of said clean dialysate flow and separates the dialysate flow into an acidic component flow and a base component flow. A mixing conduit combines the base component flow from the membrane electrolyzer and an output dialysate solution from the urease section of the sorbent component to separate the dialysate solution into an ammonia gas amount and ammonia liquid amount.

  • Publication number: 20070274893
    Abstract: A microwave plasma generating apparatus (10) has a microwave cavity (20) coupled to a microwave source (22) by a wave guide (24). Within the cavity (20) is a reaction tube (30) defining a plasma cavity (40). A gas inlet manifold (50) is provided at the top of the reaction tube (30), which is formed so as to introduce plasma gas tangentially to the longitudinal axis of the plasma. Plasma gas is thus injected into the reaction tube (30) so that it flows in a swirled manner, that is, in the form of a vortex. This prevents overheating of the reaction tube (30).
