The intended use of the Dialysis Systems Inc. Bicarbonate Mixing System is the mixing of water and sodium bicarbonate powder for hemodialysis treatment and the delivery of the mixture to the treatment floor.

Dialysis Systems Inc.'s Bicarbonate Mixing System provides for batch mixing of bicarbonate liquid concentrate and transfer to a loop tank. The mixing tank works in conjunction with an external closed-loop mixing circuit that includes a pump and an eductor. The pump circulates liquid from the mixing tank, through the eductor and back into the mixing tank. The eductor is connected to a sodium bicarbonate additive hopper. A measured amount sodium bicarbonate additive is drawn into the mixing tank by the flow of fluid through the eductor. Mixing of the powder to create a bicarbonate liquid concentrate is accomplished by the mixing action of the eductor, the return flow to the mix tank and by further mixing action created by nozzles as the fluid is re-circulated back into the mix tank.
