Heat Exchange Fluid Purification for Dialysis Systems

Abstract

Disclosed herein is a small, lightweight, portable system with the ability to reliably, reproducibly, efficiently, and relatively inexpensively provide a source of purified water in sufficient quantities for home dialysis. In addition, the system disclosed herein requires much less purified water at any one time than is typically required for dialysis today, thereby further reducing the cost of running the system at home.

AI Technical Summary

Problems solved by technology

One reason for this is that current systems are too large and heavy to fit in a typical home

Current dialysis systems are also energy inefficient as they use a lot of energy and require huge amounts of water for proper use

While some home dialysis systems are available, they generally use complex flow balancing techniques that are relatively expensive to manufacture, and most are designed with solenoid valves that cause high noise levels
