The sleek and effective design allows clinicians to examine a clear, magnified, and unobstructed view of the ear drum and surrounding areas.

FEATURES

The Battery

The Build-Your-Own-O-Scope is powered by 2 AA batteries.  AA batteries are ubiquitous, inexpensive, and can power a single LED light for tens of hours.  They also take up relatively little space, allowing for the otoscope’s sleek design.  The popularity and availability of AA batteries allows the Build-Your-Own-O-Scope to be used in a variety of settings, including low-resource areas.

Accessing the battery compartment is easy, and requires a simple twist and pull from the otoscope neck and head area, shown below.

The Specula

The Build-Your-Own-O-Scope works with Welch-Allyn winged specula (adult or child sizes).  Specula is placed on the otoscope face, and twisted to secure into place.

The Lens

The Build-Your-Own-O-Scope uses an acrylic 3x magnification lens.  The lens is encased within a seperate 3D printed housing, and can be removed from the otoscope for cleaning and sanitation.
