Embodiment Construction

[0035] figure 1 A system according to an embodiment of the invention is shown. The support 1 is flat and has a plurality of recesses 3 located in a plane around the central part 4, in which the operating device 2 is placed. It also shows the operating device 2 a outside the recess 3 . Each operating device 2 , 2 a has a flat clamping portion 5 which, as can be seen in the figure, is easily accessible even when the operating device 2 , 2 a is placed in the recess 3 . This is due to the arrangement of the recess 3 , which protrudes radially away from the central part 4 of the bracket 1 . In this case, each operating device 2 can be grasped and pulled out of the recess 3 without interfering with the adjacent operating device 2, requiring neither better dexterity nor better eyesight. Furthermore, during normal use of the stand, the opening of the recess 3 is oriented horizontally, so that the opening is unlikely to be contaminated by dust.

Abstract

The present invention includes filter manipulation devices, filters, holders for a plurality of filter manipulation devices, and systems comprising a filter manipulation device and its holder. The system comprises a filter handling device and a holder for the filter handling device, wherein the handling device has a first tool part for initially securing and subsequently releasing a filter in the sound outlet tube or vent outlet of the hearing aid. new filter, the operating device also includes a second tool part adapted to receive and fix the used filter, the operating device also includes a clamping part that can be grasped by the user, and wherein the first and second tool parts are installed side by side and Protruding from an edge portion of the clamping portion in substantially the same direction, wherein the support for the handling device comprises at least one recess for receiving at least the edge portion of the handling device, which secures the two tool parts.

Description

technical field [0001] The invention relates to a filter operating device and a filter. Filters are used in hearing aids to avoid clogging of the sound exit holes and as sound filters in the sound path from the receiver to the ear. A channel-type hearing aid has a housing that is placed in the ear canal of the hearing aid user, it also has a sound exit hole towards the inner ear, and it is connected to a telephone or receiver unit. A well-known problem is that the sound exit hole is easily blocked by earwax, which is naturally produced in the ear canal. Such blockages would reduce the output sound pressure of the hearing aid, so the sound exit holes must be protected to avoid this. Also, after ear stile hearing aids, the sound outlet of the earplug can be kept from being clogged with earwax by using a cerumen filter. Background technique [0002] PRIOR ART Earwax filter operating devices and earwax filters are known from PCT application WO 0003561 filed by Töpholm & Weste...
