    摘要: A dialysate regeneration chamber is provided. In one embodiment, the dialysate regeneration chamber may include a toxin trap configured to selectively trap toxins and repel select cations. In another embodiment, generating a toxin trap may include oxidizing an activated carbon fiber and attaching a fatty acid to the oxidized activated carbon fiber to generate an ion-selective barrier, wherein the fatty acid extends away from the activated carbon fiber.

    摘要: This disclosure relates to early detection of low bicarbonate level. In certain aspects, a method includes receiving a first signal from a conductivity detector connected to a line through which a solution of salt concentrate and fluid flows and determining a first conductivity of the solution based on the first signal. The method also includes receiving a second signal from the conductivity detector at a time after receiving the first signal, determining a second conductivity of the solution based on the second signal, and determining whether the second conductivity is less than the first conductivity by at least a threshold amount.

    摘要: The present invention constitutes dialysate formulations that are suitable for use in preparing dialysate solutions for use in batch and/or proportioning systems and for improving dialysis efficiency by reducing or preventing clotting of the dialysis flow paths. The dialysate chemical formulations for one batch of dialysate comprise an acid concentrate stored in a first vessel, and a citrate-containing bicarbonate concentrate stored in a second vessel. The contents of the first and second vessels are emptied into a dialysate preparation tank and mixed with water to form a batch quantity of dialysate solution. Alternately, a dry acid and/or a dry citrate-containing base concentrates are dissolved separately in measured quantities of water to form liquid concentrates which are then used in conjunction with a proportioning machine to generate on-line a final dialysis solution stream.

    摘要: Systems and methods for providing dialysis therapies are provided. 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.
