<p>The invention concerns a device (1) for affecting the hydrodynamic system of the internal ear, said system including the perilymph and the endolymph. The device is formed with a first means (7, 8, 10, 12, 13, 15, 17) for generating a desired static-pressure level, a second means (14, 16, 18) for causing a variation of the static-pressure level, a third means for connecting said first means (7, 8, 10, 12, 13, 15, 17) and said second means (14, 16, 18) to the internal ear for transferring the generated pressure changes. The second means (14, 16, 18) is arranged to affect the static pressure level upon predetermined pressure changes in accordance with a predetermined program controlled by a control unit (29). The first means (7, 8, 10, 12, 13, 15, 17) includes a medium pump for generating the desired static-pressure level in a medium reservoir (9). The second means (14, 16, 18) includes a unit (16, 18) for causing movements of a membrane part (14) which is connecte to the reservoir (9). These movements are arranged to cause variations of the static-pressure level. The membrane part (14) has a predetermined area, and the unit (16, 18) is arranged to affect the membrane part (14) by a force of a certain magnitude to generate said pressure changes.</p> |
