Improvement of a Handheld Veterinary Otoscope
Problem statement
Imagine your dog has an ear infection that goes undiagnosed simply because a veterinary student was unable to practice with the right tools. Otoscopic exams are an essential part of the physical exam for animals, but veterinary students often struggle to gain realistic and consistent training. In practice, an otoscope is typically a handheld device with a magnifying lens and light source, used to examine the ear canal for signs of infection or issues. Current training options for these either rely on handheld otoscopes with self-reported findings, or video otoscopes that do not replicate the feel of actual clinical tools due to significant design differences. While a prototype combining a handheld otoscope design with a wireless camera has been developed, it lacks durability for repeated use by groups of students and does not fully replicate the experience of a handheld otoscope. This could affect the results of an otoscopic exam, leading to inconclusive or deceptive outcomes for our client’s patients. Additionally, the existing design is not easily reproducible or repairable, which limits its scalability for multiple users in a teaching setting. Research has shown that video otoscopes can improve student confidence and diagnostic skills by allowing both students and instructors to view findings simultaneously, yet these devices still fail to provide the experience of clinical otoscopes used in practice [1]. Our client requires a more robust solution that withstands frequent use, incorporates a metal housing, and maintains the authentic experience of using a clinical otoscope. Further improvements, such as a disposable plastic cone and an adjustable light source, would enhance both usability and hygiene. Ultimately, our solution will allow veterinary students to gain realistic, hands-on training while giving instructors direct insight into their diagnostic skills.
