System using balancing chambers

Abstract

Disclosed are example embodiments of a dialysis system that enables real-time preparation and delivery of peritoneal dialysis solution using a balancing chamber architecture. The system includes a water purification module configured to convert tap water into purified water meeting dialysis quality standards, and a mixing subsystem configured to combine the purified water with an osmotic agent, electrolytes, and a buffer to produce peritoneal dialysis solution on demand. A balancing chamber having a fresh side and a spent side is used to precisely meter delivery of the solution to a patient, with pressure applied to the spent side through a recirculation pathway. The system further includes fluid pathways for delivering the prepared solution to the patient and for removing fluid from the patient, under control of a controller that manages fluid flow and dosing accuracy. By integrating real-time solution preparation with balancing chamber-based fluid control, the system improves flexibility, reduces reliance on pre-mixed solutions, and enhances treatment efficiency.
