The invention relates to a sorbent for removing metabolic waste products from a dialysis liquid, the sorbent comprising a soluble source of sodium ions. The sorbent comprises an ion exchange system which converts urea to ammonium ions and which is configured to exchange ammonium ions for predominantly hydrogen ions and to exchange Ca, Mg, and K for predominantly sodium ions. The soluble source of sodium ions overcomes an initial drop in sodium concentration in regenerated dialysate. When used in conjunction with an infusion system configured to utilise exchange of Ca, Mg and K for sodium during dialysate regeneration a desired sodium ion concentration can be maintained.

The present invention relates to a urease introduction device and scheme for a dialysis fluid regeneration system. The device includes a storage part, a refrigeration part and a heat exchange part. The structure of the storage part includes a pressure chamber for storing pure urease. The structure of the heat exchange part includes a fluid passage for allowing the dialysis fluid to pass through. The refrigeration part uses a semiconductor refrigeration component, whose cold end is used to conduct cold to the pressure chamber to provide a low-temperature storage environment for pure urease, and the hot end is used to conduct heat to the fluid passage to heat the dialysis fluid. The present invention creatively provides low-temperature preservation conditions for pure urease, realizes the real-time and quantitative introduction of pure urease in the dialysis fluid regeneration system, and ensures the activity and treatment efficiency of the urease solution during its use in an artificial kidney. Using pure urease to treat urea has a high efficiency that cannot be achieved by the existing fixed urease introduction method. Moreover, the heat of the hot end of the refrigeration part is recovered for heating the dialysis fluid, improving the energy utilization rate.
