Systems, devices and methods for peritoneal dialysate production and delivery

A method for performing peritoneal dialysis in a patient, comprising:

• performing a disinfecting stage with a disinfecting agent for disinfecting at least part of a tubing employed for producing and/or delivering a fresh dialysate to a patient, wherein the method employs a portable peritoneal dialysate production and delivery (PD) system comprising:
• a water treatment device fluidly connectable or connected via a water inlet to a water source and configured to treat water received from the water source to generate treated water;
• a concentrate supply device in fluid communication with at least one of water treatment devices and configured to add concentrate contained in the concentrate supply device to the treated water to generate fresh dialysate fluid;
• a tubing having a lumen for supplying the fresh dialysate fluid to a patient body via a flow path;
• a tubing disinfectant supply device configured to contain and/or to receive disinfectant agents, wherein the tubing disinfectant supply device is in fluid connection with the tubing for disinfecting at least a portion of the tubing;
• and
• a bypass flow path fluidly connecting the water source with the tubing disinfectant supply device by bypassing the water treatment device and/or the concentrate supply device.
