A loading platform and chemical addition system are described for a machine that prepares a batch of dialysate. The loading platform is in fluid communication with a dialysate preparation tank, and receives chemical vessels that contain a batch quantity of dialysate chemicals. The chemicals are released from the vessels automatically and fall onto a shelf in the loading platform. Nozzles and spray equipment are provided for insuring the complete release of the chemicals from the vessels and their dispersion into the tank. Novel mixing techniques are implemented in the tank to insure complete mixing of the dialysate solution and prevention of settling of dialysate solution at the bottom of the tank.

A dialysate tank and mixing apparatus for preparation of a batch of dialysate solution, comprising: a hollow, closed tank having an interior region and a top, sidewalls and a bottom; a first inlet disposed at said bottom of said tank through which fluids are introduced into said tank, said inlet directing incoming water substantially tangential to said sidewalls of said tank so as to create a vortex in said tank; spray means suspended above said bottom of said tank within said interior region of said tank for spraying fluids within said tank, said spray means spraying said fluids in the same direction as water is introduced into said tank through said inlet; said water inlet and said spray means cooperating to mix said fluids within said tank and prevent settling of dialysate chemicals at said bottom of said tank; a recirculation loop comprising an outlet at the bottom of said tank, a second inlet at the top of said tank, and fluid circuitry connecting said outlet with said second inlet for circulation of fluid from said bottom of said tank to said top of said tank, with said spray means in fluid communication with said fluid circuitry, said recirculation loop cooperating with said water inlet and said spray means in promoting mixing of said dialysate solution in said tank; and a dialysate chemical addition system in communication with said tank, said chemical addition system comprising a housing having an exterior surface and an interior region and a chemical receiving port in said exterior surface, and a mounting means on the exterior or said housing in registry with said chemical receiving port for receiving a bottle containing batch dialysate chemicals and further comprising an opening means for opening said bottle to release said chemicals, said chemical addition system further comprising a nozzle positioned between said mounting means and said chemical receiving port oriented such that fluids are sprayed from said nozzle into said bottle when said bottle is mounted to said mounting means and opened by said opening means.
