Abstract: A hearing restoration system with a housing having a user interface, a pump, control circuitry, and at least one pneumatic port. The hearing restoration system comprises one or more pneumatic ports, which are connected fluidly to one or more tubes. Furthermore, the housing may have a vacuum chamber fluidly connected to the third pneumatic port. A control circuitry is configured to detect a mode of operation of the system based on a measurement of pressure or vacuum inside the hearing aid restoration apparatus.

Abstract: A video otoscope comprises an image forming assembly for producing an optical image of selected portions of an ear canal and a video camera for converting the optical image into a video image and transmitting the video image to a display system. The image forming assembly includes a speculum portion at a front end thereof, an optical lens system, and a coupling mechanism connecting the video camera to a rear end of the image forming assembly. The optical lens system is disposed along a longitudinal axis extending from a front distal end of the speculum portion to the video camera. The optical lens system includes an objective lens means disposed adjacent the front distal end and expander lens means spaced rearwardly from the objective lens along the longitudinal axis. Conically shaped inner taper tube surface defines a trapezoidal chamber portion around an optical image path that extends in a direction parallel to the longitudinal axis of an inner optical passage.
