Method, System and Device for Water Conservation and Dialysate Recycling

Case ID:
UA23-272
Invention:

The technology is a method to recycle water that is used during dialysis. By using activated charcoal, urease, zirconium oxide and zirconium phosphate to filter the water of contaminants, this method can make water achieve a purity level that is acceptable for clinical reuse.

As dialysis becomes an essential treatment for an increasing number of patients globally, the need for water conservation in the process is paramount. By allowing water to be recycled for clinical reuse, this technology not only contributes to environmental sustainability but also ensures a steady supply of purified water for uninterrupted dialysis sessions.

Background: 
Dialysis is a method used to eliminate waste substances and surplus fluids from the bloodstream in situations where the kidneys are not functioning adequately. Typically, this process entails redirecting the blood to a specialized machine for thorough purification (NHS). Current systems use a hollow fiber kidney system to exchange fluid, electrolytes, and waste with dialysate. However, these systems are non-portable, requiring access to a large water and dialysate source in a hospital or clinic setting. The new technology aims to fix that by recapturing dialysate and water, so that it can be reused.

While traditional dialysis procedures are effective in their purpose, the consumption of water in large quantities remains a concern. Modern medical advancements necessitate the development of more sustainable methods, ensuring both the well-being of patients and a reduced ecological footprint. The introduction of technologies that promote the efficient use of resources in medical treatments is a step forward in achieving a balance between healthcare and environmental conservation.
