Flow system of a dialysis device and a portable dialysis device

A flow system of a dialysis device comprising:

• a single dialysate conduit which is capable of being in fluid communication with a peritoneal cavity of a patient's body and of being in fluid communication with a flow path, said flow path allowing dialysate to flow from the patient's body to a sorbent capable of removing contaminants within said dialysate in an outflow mode and in an inflow mode returning said dialysate substantially free of contaminants to said patient's body;
• a single pump for moving said dialysate along said flow path in both the outflow mode and inflow mode;
• a plurality of valves disposed along said flow path and being configured to, in the outflow mode, allow said dialysate to flow from said dialysate conduit to said sorbent for removal of contaminants therein, and in the inflow mode, allow dialysate substantially free of said contaminants to flow back to said dialysate conduit for transmission to said patient's body;
• and
• a storage module in fluid communication with said flow path,
• said storage module configured to store dialysate that is substantially free of contaminants which have been removed by said sorbent,
• wherein the dialysate flows through the sorbent in the outflow mode and dialysate substantially free of said contaminants does not flow through the sorbent in the inflow mode.
