This master’s thesis presents a comprehensive redesign of the vaginal speculum, an essential yet historically problematic device used in women’s healthcare. The project focuses on addressing three main issues: enhancing patient comfort, fulfilling physician needs, and ensuring environmental sustainability. This work aims to resolve the persistent discomfort and anxiety associated with pelvic exams, which are exacerbated by the current design of the speculum, while also considering the environmental impact of the healthcare sector.

The vaginal speculum has seen little change since its invention in 1845, despite its controversial history and the discomfort it causes to patients. Traditionally, its design prioritized the needs of healthcare providers, often neglecting the experience of the patient. The discomfort caused by the device has been a significant deterrent for women undergoing gynecological examinations, contributing to delays in the diagnosis and treatment of various health conditions. While some modern adjustments have been made—such as the shift from reusable metal speculums to single-use plastic versions—these changes have increased the environmental burden of healthcare, particularly in the context of global greenhouse gas emissions.

The project followed the three diamond design method, encompassing the phases of Discover, Define, Ideate, Conceptualize, Develop, and Deliver, to create a new speculum design. The process began with an in-depth exploration of the needs of three primary stakeholders: patients, healthcare providers, and the environment. This included literature reviews, hands-on explorations, and interviews to understand the diverse perspectives and challenges faced by each group.

The resulting design, named "Lilium," integrates patient-centered features such as improved ergonomics, reduced invasiveness, and enhanced aesthetics to alleviate patient discomfort. For healthcare providers, the design offers a more efficient and user-friendly tool that facilitates better access and visibility during examinations. In terms of sustainability, the Lilium speculum is designed for reusability, with a focus on materials that reduce environmental impact while maintaining high standards of hygiene and safety.
