Otoscope for Teaching Purposes

Client: Murray Katcher, M.D., Ph.D.
Group Members: Tom Pearce, Elese Hanson
Advisor: Willis Tompkins, Ph.D.
One of the most common skills that physicians are expected to master is the use of an otoscope to diagnose ear infections as well as other problems with the eardrum. However, it can be exceedingly difficult to obtain a clear image of a small child’s eardrum with the current model of teaching otoscope. This otoscope also has the disadvantage that the student’s view is a mirror image of the actual eardrum, which can complicate the diagnosis process. This paper explores various alternatives to the current model in use by our client, including the use of fiberoptic video cameras, regular video cameras, and a modification of the current model to allow photographs with a digital camera. Commercial video otoscopes are available, but at a cost prohibitively high to our client.
To design an otoscope capable of recording images for use as a teaching tool for both practicing physicians and medical students.
Description of product function:
The device should be capable of obtaining and recording high-quality images of a human eardrum. It must be easy to use for the physician under all clinical circumstances that may arise, at least as good as the current model of teaching otoscope. Preferably the captured image will not be reversed from the actual eardrum in order to more accurately represent reality.
Client’s statement of product requirements:
The client wants an otoscope capable of recording faithful images of a human eardrum. It is important that the device be easy to use, because a major use is the diagnosis of ear infections in small children and infants. This demographic presents challenges to the physician, because the patient is rarely calm, often times screaming and...
