Abstract

A tip element for an otoscopic apparatus includes engagement features that permit selective attachment to two different tip attachment mechanisms. The tip element includes both interior and exterior engagement features that provide interchangeability with otoscopes having different tip attachment schemes. The tip element includes an increased distal aperture formed from a decreased slope that enables a larger field of view, permitting the entire tympanic membrane to be viewed at once. External engagement features permit ejection of the tip element from the otoscope, as well as stackability of a plurality of tip elements.
