Summary:
ISU researchers have developed a technology that would allow for miniaturized dialysis by eliminating the need for the large dialysate reservoirs currently required.

Development Stage:
Description:
1.3 million patients world-wide have chronic kidney failure that requires treatment with dialysis or organ transplantation. Hemodialysis attempts to replace the role of functioning kidneys by removing excess fluid, salt, and waste products, such as urea. Traditional dialysis removes waste products from blood by passing it into a dialysate liquid through a molecular weight cutoff filter. This dialysis traditionally requires large immobile equipment and the treatment is often administered in the hospital or satellite hemodialysis units. A portable option, the wearable artificial kidney (WAK),  for dialysis has recently become available that would allow for more frequent treatment, and treatment that is easier to do at home while also improving the quality of life for patients who require frequent dialysis. However even the wearable units available still require large liquid reservoirs of dialysate to be attached. Replacing these reservoirs would be a key factor in further miniaturization. ISURF #04547 proposes a new dialysis supplementary device that removes the requirement for a dialysate reservoir. The device uses ion concentration polarization and downstream processing to source dialysate from excess fluid in the patient’s own blood.

Advantage:
• Allows for easier at home dialysis care
• No bulky dialysis reservoir needed
