Module for in-line recharging of sorbent materials with optional bypass
First Claim
Patent Images
1. A method of recharging a sorbent for dialysis, comprising the steps of:
- connecting at least one reusable module containing either zirconium oxide or zirconium phosphate, and a second module in series with one or more connectors, wherein the reusable module and second module each contain one or more sorbent materials;
fluidly connecting at least one connector to at least one wash line, wherein the wash line is fluidly connected to a recharger;
fluidly connecting at least one connector to at least one bypass line, wherein the bypass line diverts flow from the connector to bypass at least one module;
connecting a valve assembly to the connectors at junctions between the modules, wash lines and/or bypass lines;
the valve assembly including a first valve positioned on a connector;
connecting the first valve to a wash line and a bypass line;
flowing spent dialysate through the reusable module and the second module; and
selectively opening and closing the valve assembly to direct flow from the recharger, through the wash line, and through at least the reusable module to recharge the zirconium oxide or zirconium phosphate.

Abstract
This disclosure generally relates to at least one reusable module of a sorbent cartridge in a sorbent dialysis system and a method of using the same. One of the drawbacks of a conventional sorbent dialysis system is the high cost. In one aspect of the invention, the sorbent cartridge contains at least one module for optionally recharging sorbent materials in-line with an optional bypass and conduits for the sorbent cartridge. The sorbent cartridge can have two or more modules that are connected to one another through connectors. The modules can be reusable and the sorbent materials contained in the modules can be recharged.
