An otoscopic instrument includes an instrument head attached to a handle and a speculum tip actuator mechanism for receiving, retaining and selectively ejecting an otoscopic speculum tip element. The tip actuator mechanism includes an actuator knob rotatably attached to the instrument head in which the instrument head includes annular securement slots sized for receiving external engagement features of a speculum tip element which are rotatably fitted into the slot(s). The actuator knob further includes a pin for displacing a secured speculum tip element from the securing slot upon rotation in a predetermined direction in order to eject the tip element.

A tip for coupling sound between a medical instrument and an ear includes a sealing surface configured to substantially conform the tip to an auditory canal of the ear. The tip includes an acoustic tube acoustically coupled to at least one of the plurality of openings and defining a first acoustic path. The tip also includes a second acoustic path acoustically coupled to at least another one of the plurality of openings in the sealing surface. The acoustic tube of the first acoustic path is configured to substantially acoustically isolate the first acoustic path from the second acoustic path. A tympanometric instrument is configured to use the tip and to provide an acoustic measurement of the ear of a patient.

Acoustic measurement tip

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.
