Abstract: A manual ear pump including one or more of a support element configured to releasably engage an external ear canal and having an interior chamber, a resilient element capable of being resiliently deformed coupled to a support element, and an aperture disposed on a support element bottom surface communicating with the external ear canal and interior chamber.

Abstract: Provided is an auditory sensitivity adjustment device suitable to enhance concentration and attentiveness in any direction. An auditory sensitivity adjustment device 100 includes grab parts 32a and 32b for holding a pinna 50, springs 22 for applying to the grab parts 32a and 32b a force for pulling, in an extending direction, the pinna 50 held by the grab parts 32a and 32b, and a base 38 for rotating the pinna 50 held by the grab parts 32a and 32b so as to twist the pinna 50.

Abstract: The invention relates to a stimulation device (1) for erogenous zones, in particular for the clitoris (12), which device (1) has at least one pressure field generator (2) with at least a first chamber (3) and at least a second chamber (4) with at least one opening (42) for placing onto a body part (11), and at least one connection element (5) which connects the first chamber (3) to the second chamber (4), and with a drive unit (6) which changes the volume of the first chamber (3) in such a way that, by way of the connection element (5), a pressure field is generated in the second chamber (4) and serves for stimulation; and a control device (7) which controls the drive unit (6).

Abstract: An ear canal pressurization device optimized for aural acoustic immittance testing is disclosed. Changes in volume of a first flexible chamber, due to motor movement, produce changes in ear canal pressure based on Boyle's law. A vent may be opened to allow ear canal pressure to gently equalize to ambient air pressure or to generate ear canal pressure sweeps free of pressure baseline offset. The vent may be closed to set a static ear canal pressure or to generate ear canal pressure sweeps with an incidental baseline offset. The vent may be controlled to generate ear canal pressure sweeps with an intended baseline offset. The device produces ear canal pressure proportional to drive voltage, so any desired pressure versus time function can be generated by applying a coil driving voltage with the appropriate amplitude versus time function.

Abstract: The invention refers to a feeder for dosing air in small quantities or pressure pulses to the external auditory meatus of a person with vertigo e.g. Ménière's disease. The feeder includes a pump body (10) with a through hole (12), one end (14) of which is connectable to an ear adapter by a flexible tube and the other end (15) of which is provided with an air pump device (16). The pump body (10) of the air pump device (16) has a manually impressionable, temporarily adjustable volume in providing a quantity of air with a pulsating overpressure of a repeatable and adjustable size.
