Abstract
The disclosure relates to systems and methods for increasing the functional capabilities of a sorbent-based dialysis system. The systems and methods allow for the mode of operation of the dialysis system to be switched between single pass mode and a sorbent based multi-pass mode by controlling an amount of water added to the dialysate between 0% to 100% of the dialysate flow rate.
Claims18
A system comprising:
- a fluid flow path comprising:
- a dialyzer outlet fluidly connectable to a dialyzer;
- a first valve fluidly connecting the fluid flow path to a drain line;
- a sorbent cartridge positioned downstream of the first valve;
- a second valve fluidly connecting the fluid flow path to a water source;
- and
- a dialyzer inlet downstream of the sorbent cartridge;
- and
- a control system,
- wherein the control system is programmed to control a mode of operating the fluid flow path between a first mode of operation and a second mode of operation by controlling a water addition rate using the first valve and the second valve,
- wherein one of the first mode of operation and the second mode of operation is a hybrid mode,
- wherein, in the hybrid mode, at least a first portion of a fluid in the fluid flow path is diverted to the drain line and while the at least first portion of the fluid is diverted to the drain line, at least a second portion of the fluid simultaneously remains in the fluid flow path;
- and
- wherein the control system is programmed to temporarily switch the mode of operation during a dialysis session based on a detected condition of the fluid flow path, until the detected condition is resolved.

A system comprising:
- a fluid flow path fluidly connected to a dialyzer comprising:
- i) a first valve fluidly connecting the fluid flow path to a drain line;
- and
- ii) a second valve fluidly connecting the fluid flow path to a water source;
- and
- a control system,
- wherein the control system is programmed to control a mode of operating the fluid flow path between a plurality of modes of operation by controlling a water addition rate,
- wherein a first mode of the plurality of modes of operation is a single pass mode and a second mode of the plurality of modes of operation is a hybrid mode,
- wherein, in the single pass mode, all of a fluid that passes through the first valve is diverted to the drain line,
- wherein, in the hybrid mode, at least a first portion of a fluid in the fluid flow path is diverted to the drain line and while the at least first portion of the fluid is diverted to the drain line, at least a second portion of the fluid simultaneously remains in the fluid flow path, and water is pumped into the fluid flow path from the water source;
- and
- wherein the control system is programmed to switch the mode of operation during a dialysis session to the single pass mode when a concentration of solutes in the fluid is detected and is programmed to switch the mode of operation back to the hybrid mode when the concentration of solutes in the fluid reaches a threshold level.
