Abstract:
1. A system for use in a dialysis apparatus, the system comprising: a fluid source; at least one line adapted to allow the passage of fluid, the hydraulic line having a first end in fluid communication with the fluid source and a second end in fluid communication with a drain; an inlet pump disposed along the hydraulic line and in fluid communication with the fluid source; a container containing a powdered salt concentrate, the container having an inlet and an outlet, the inlet being adapted to receive fluid from the inlet pump, and the outlet adapted to pass a solution of the fluid and the salt concentrate; a valve disposed between the inlet pump and the container and downstream from the inlet pump and in fluid communication with the hydraulic line, the valve being disposed to selectively divert fluid flow from the hydraulic line to the inlet of the container; a pressure sensor disposed to monitor pressure in the container; the outlet of the container in fluid communication with the hydraulic line downstream from the bypass valve; and a controller configured to control operation of at least one of the inlet pump and the valve in response to pressure data provided from the pressure sensor.
