A set of bottles for containing dialysate chemical formulations, chemical cleaning agents or the like is described. The chemical formulation bottles come in two varieties, sodium bicarbonate and liquid acid formulations, each bottle having a slightly different shape. The different shapes cooperate with a bottle mounting structure in the dialysis machine to insure that bottles are correctly installed on their respective bottle opening mechanism. The bottles also have a detection feature comprising either a raised rim or groove extending around the periphery of the bottle. A sensor assembly in the bottle mounting and opening system detects the detection feature. The detection feature is used by the machine to distinguish between dialysate formulation bottles and chemical cleaning bottles, which do not have the detection feature. The detection feature prevents unintentional installation of the chemical bottle on the opening mechanism for the dialysate chemical formulation bottles. A chemical loading system for use with the bottles, and having a detection system for detecting the detection feature is also described.

The present invention constitutes dialysate formulations that are suitable for use in preparing dialysate solutions for use in batch and/or proportioning systems and for improving dialysis efficiency by reducing or preventing clotting of the dialysis flow paths. The dialysate chemical formulations for one batch of dialysate comprise an acid concentrate stored in a first vessel, and a citrate-containing bicarbonate concentrate stored in a second vessel. The contents of the first and second vessels are emptied into a dialysate preparation tank and mixed with water to form a batch quantity of dialysate solution. Alternately, a dry acid and/or a dry citrate-containing base concentrates are dissolved separately in measured quantities of water to form liquid concentrates which are then used in conjunction with a proportioning machine to generate on-line a final dialysis solution stream.

A medical fluid machine, such as a dialysis machine, includes a pump that pumps a medical fluid and sterile water or other disinfecting liquid, such as ozonated water, for flushing and reconditioning the medical fluid machine. The machine may also include a heater that heats the medical fluid or disinfecting solution in order to kill bacteria and other microorganisms that may contaminate the machine after use. Disinfecting the machine, and a disposable kit used with the machine, may allow re-use of the disposable within a reasonable amount of time after completion of the disinfecting procedure. Dialysate treated with ultra-violet light or water with low concentrations of ozone also helps make the disposable kits suitable for reuse.

A batch of dialysate solution is made from a mixture of bicarbonate formulation and a liquid acid formulation. The liquid acid formulation is introduced into a dialysate tank and then removed from the tank and stored elsewhere, such as in an ultrafiltration tank, where it is diluted with a few litres of water. The dialysate tank is then filled with water and the bicarbonate formulation is added to the dialysate tank. The bicarbonate formulation is mixed and dissolved by circulation in a closed loop, with the liquid acid formulation kept separate. When the bicarbonate solution has been prepared, the liquid acid solution and the bicarbonate solution are mixed together and stored in the dialysate preparation tank. An additional quantity of dilution water is introduced into the dialysate system to bring the final conductivity down to the desired range. The excess dialysate solution can be used for several purposes, such as an endotoxin flush of the blood tubing set or a dialyzer clearance test.
