Abstract

This thesis presents the development of a home healthcare concept for a product designed to measure CRP (C-reactive protein) levels. The project was commissioned by the research and development team at Plasmantic and carried out by a dedicated design group. Through extensive user studies and usability research, the team developed a concept that fulfills the majority of the defined requirements. These requirements were based both on the specifications provided by the project team and on additional criteria established by the design group. These included considerations related to ergonomics, regulatory standards for home medical devices, technical feasibility, and sustainability. The final concept emphasizes long product lifespan through maintainability and modular design, cost-efficiency by minimizing the size and waste of disposable components. Although the concept does not achieve a fully minimalistic testing process due to technical requirements such as the manual mixing of buffer solution to ensure reliable outcomes, this added procedural step is considered a justified compromise. It enhances the accuracy and clinical reliability of test results, provided the procedure is conducted in strict accordance with the product’s usage guidelines.
