Abstract

An apparatus for preparing dialysate solution directly from a dry chemical mix for continuous supply to a dialysis machine is disclosed. The preferred embodiment includes a drum for containing the dry chemical mix, a conveyor belt, a mixing vessel and monitoring equipment. The drum includes internal baffles that cause the dry chemical to be deposited onto the end of the conveyor belt as the drum rotates. The conveyor belt passes the chemical through a profile-determining gate and into the top of a funnel-shaped mixing vessel. The rate at which the conveyor belt delivers the chemical to the mixing vessel is governed by an electronic circuit that measures the conductivity of the dissolved solution and adjusts the belt speed as necessary to maintain the conductivity at a set value. The dissolved solution flows out the side of the mixing vessel and into a flow controller which regulates the rate at which dialysate can be withdrawn.
