In a general embodiment, the present disclosure provides an apparatus for dialysis treatment comprising first and second fluid flow pathways in a parallel arrangement. The first fluid flow pathway contains a first cation exchange resin, wherein greater than 90% of exchange sites of the first cation exchange resin are populated with hydrogen ions. The second fluid flow pathway contains a second cation exchange resin, wherein greater than 90% of exchange sites of the second cation exchange resin are populated with sodium ions. The apparatus can be used to maintain a constant and safe level of sodium in a constantly regenerated dialysis fluid over an extended period of time.Type: ApplicationFiled: July 29, 2011Publication date: January 31, 2013Applicants: BAXTER HEALTHCARE S.A., BAXTER INTERNATIONAL INC.Inventors: Yuanpang Samuel Ding, Rongsheng Lin, Ying-Cheng Lo
