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

Embodiment approach

[0085] Figure 5 is a schematic cross-sectional view of a dialyzer 15 defining a blood chamber with a blood flow path 205 and a dialysate fluid chamber with a dialysate flow path 210 separated by a transfer layer consisting of a semi-permeable membrane 215 . In one embodiment, the dialyzer includes one or more microfluidic pathways, such as microflow fields and / or microchannels. Exemplary embodiments of dialyzers and / or flow field dialyzers employing microflow fields and / or microchannels are described in U.S. Patent Publication No. 2010 / 0326914, filed June 7, 2010, which is incorporated by reference It is incorporated herein in its entirety. However, the dialysis system can use any of a variety of dialyzers, including a variety of commercially available dialyzers.

[0086] Blood (from the patient) may enter blood flow path 205 through blood inlet 216 , flow through blood flow path 205 , and exit through blood outlet 217 . Dialysate may enter dialysate flow path 210 through...

Abstract

Disclosed herein are small, lightweight, portable, systems that have the capability of reliably, reproducibly, highly efficiently and relatively inexpensively providing a source of purified water of sufficient volumes for home dialysis. In addition, the systems disclosed herein require much less purified water at any one time than the volumes typically needed for dialysis today, thereby further reducing the expense of running the system at home.
