Refinement of an Ultraviolet Light Sanitation Device for Central Lines; Closing the Gaps in Healthcare Using Technological and Social Advancement

Year: 2025
Type: dissertation
Abstract: The technical project focuses on designing a UV-C sanitation cartridge for central lines to prevent intraluminal contamination and reduce central line–associated bloodstream infections (CLABSIs). Using 3D printing, fluid modeling, and thermal testing, the device delivers a two-second UV exposure at clinical flow rates, achieving ≥4-log bacterial reduction without degrading medications. The cartridge is compact, cost-conscious, and designed for seamless integration in resource-limited hospitals.The STS research examines why technologies like the medical device being developed often fail to reach under-resourced institutions. Wealth disparities, regulatory biases, and reimbursement models contribute to delayed adoption and unequal access. Underrepresented populations frequently face device failures due to design and testing exclusions, undermining trust and outcomes. To bridge this gap, the research advocates for equity-focused design, inclusive clinical testing, outcome-based reimbursements, and regulatory reforms.Together, the projects propose a roadmap for responsible innovation—where technical efficacy is paired with social accountability. By addressing both device performance and systemic barriers to access, this thesis argues that medical technologies can be leveraged not only to heal but to advance justice in healthcare delivery.
