Abstract: Dialysis systems for operating dialysis machines (e.g., peritoneal dialysis machines) for conducting dialysis treatments are disclosed. The dialysis system may include a spent dialysate container for receiving spent dialysate from a patient. In use, the spent dialysate containers are arranged and configured to provide one or more mechanical advantages to ease disposal of the spent dialysate. For example, the spent dialysate container may receive the spent dialysate from the patient and enable the patient or caregiver to dispose of the spent dialysate without requiring the patient or caregiver to lift bags of spent dialysate or incorporate lengthy drain lines. The spent dialysate container may include a reservoir to receive the spent dialysate, wheels to enable the patient or caregiver to transport the reservoir, mechanisms to facilitate disposal of the spent dialysate from the reservoir, a nozzle to dispose of the spent dialysate, and/or a disinfectant to disinfect the drain.
