Patent ID: 8889004

Claim:
A dialysis system, comprising: a module that is connected to a dialysis machine, the module comprising: a device adapted to remove one or more substances from a dialysis solution as the dialysis solution passes through the device; a foldable holder configured to retain the device in a manner such that the dialysis solution can pass through the device; a fluid line in fluid communication with the device; a sodium control system in fluid communication with the fluid line, the sodium control system being adapted to alter a sodium concentration of dialysis solution passing through the fluid line; a first container that stores a diluent, the diluent being stored separately from an infusate solution that provides at least a portion of the dialysis solution; a first pump that moves dialysis solution from the module into the dialysis machine; a second pump that moves diluent from the first container into the module; and a processor configured to control the first pump to move dialysis solution from the module into the dialysis machine and configured to control the second pump to move diluent from the first container into the module.
