Simplifying dialysis

Degree Project 2026

As the global prevalence of chronic kidney disease (CKD) continues to rise, healthcare systems face an increasing demand for dialysis treatment alongside limited clinical capacity. This project explores how at-home dialysis treatment can be made a more accessible, sustainable and attractive option for patients living with CKD. Through research, interviews, prototyping and user testing the project looks in to how reducing the practical and psychological burden of dialysis can encourage more patients to consider home dialysis. The outcome is PTR, a system that produces dialysate directly in the patient’s home, making the heavy lifting, transportation and storage seen in conventional peritoneal dialysis obsolete. By integrating PTR into home dialysis, the system can restore a sense of freedom and dignity for patients while at the same time support a more sustainable healthcare future.

Methods

Research involved studying literature on chronic kidney disease, dialysis methods, water purification systems, and sustainability issues related to dialysis treatment. Interviews were conducted with a relative to dialysis patients, healthcare professionals, and representatives from kidney disease organizations to understand practical and emotional challenges linked to home dialysis.

Concept development aimed to simplify dialysate handling and reduce the space taken up by dialysis equipment in homes. Multiple concepts were explored through conversation, sketching, CAD development and physical prototypes. User testing and discussions with patients and design professionals occurred throughout the process to assess ergonomics, interaction, placement within the home. The final design was improved through repeated prototyping and scenario-based evaluations.

Result

The final result is PTR, a compact dialysate production system for home use. This system makes peritoneal dialysis fluid right in the patient’s home through an integrated purification and mixing process. It cuts down on the need for frequent deliveries and large storage of dialysate bags. The design blends medical functionality with a softer, furniture-like look to fit better into home environments.

PTR has a removable dialysate module that makes it easy to set up dialysis treatment and simplifies interaction for both patients and service personnel. The design also includes a replaceable cassette that stores chemical cartridges to improve usability, maintenance, and long-term sustainability. By reducing logistical complexity and making home dialysis feel less clinical and intrusive, PTR seeks to make self-care treatment more accessible, supporting greater independence, freedom, and dignity for dialysis patients.
