ABSTRACT:
This invention is an improvement in otoscopes for ear examinations and the like wherein disposable ear funnels are ejected from the instrument remotely thus avoiding contact by the examiner after use. An ejector is provided in the head portion of the housing of the instrument between the magnifying eyepiece and the ear funnel. The eyepiece is movably mounted so that it can be depressed to engage and move the ejector to thereby eject the ear funnel.
