Patent ID: 8597223

Claim:
A device for use in dialysis comprising the combination of: i. a container having an interior area in which solid form salt concentrate is mixed with water, and ii. a bed of solid form salt concentrate contained in said interior area of said container prior to use of said device so that only water is introduced into said container for mixture with the salt concentrate in the interior area when the device is used; said container having an inlet for water and an outlet that is connectable to a dialysis machine, said inlet and said outlet being located adjacent one another and both the inlet and the outlet being positioned in direct proximity to said bed of solid form salt concentrate contained in said interior area of said container and each having a respective filter therein to prevent any undissolved salt concentrate from leaving the container, said device being configured so that water entering the interior area of the container through the inlet is saturated in said container during continuous operation by said water passing through an entire bed of said salt concentrate a first time after incoming through said inlet as a first flow in a first direction and passing through an entire bed of said salt concentrate a second time to mix with said salt concentrate before exiting said container through said outlet as a second flow in a second direction counter current to said first direction, said first and second flows occurring concurrently and being in direct proximity to one another inside the container so that said flows themselves create a turbulent flow around the salt concentrate for saturation of said water.
