Abstract
Description
本発明は、液体状の耳垢や外耳道内に分泌される油などの液状物質が補聴器の内部に侵入するのを防止する液状物質の侵入防止構造を備えた補聴器に関する。 The present invention relates to a hearing aid having a liquid substance intrusion prevention structure that prevents liquid substances such as liquid earwax and oil secreted into the ear canal from entering the inside of the hearing aid.
耳あな形補聴器では、補聴器が外耳道に挿入される時に、その先端が掻き取った外耳道の壁部に付着していた耳垢が、音口から補聴器内部に侵入しないように音口にフィルタの役割を果たす多数の細かな孔を開けた交換可能な耳垢防止チップを取り付けている（例えば、特許文献１参照）。 In the ear-shaped hearing aid, when the hearing aid is inserted into the ear canal, the earpiece attached to the wall of the ear canal, whose tip has been scraped off, acts as a filter in the mouth so that it does not enter the hearing aid from the mouth. A replaceable earwax prevention chip having a number of fine holes is attached (for example, see Patent Document 1).
特許文献１に記載のように、音口に多数の細かな孔を開けたフィルタからなる耳垢防止チップを取り付ければ、固形物の耳垢が補聴器の内部へ侵入するのを防ぐことができる。
しかし、液体状の耳垢や外耳道内に分泌される油などの液状物質は、耳垢防止チップを通過して補聴器の内部へ侵入し、出力音の調整を行う音響ダンパのメッシュ部を詰まらせ、その結果補聴器から音が出なくなり、更にイヤホンなどの故障原因になるという問題がある。
As described in Patent Document 1, if an earwax prevention chip comprising a filter having a large number of fine holes is attached to the sound port, solid earwax can be prevented from entering the hearing aid.
However, liquid substances such as liquid earwax and oil secreted into the ear canal pass through the earwax prevention chip and enter the interior of the hearing aid, clog the mesh part of the acoustic damper that adjusts the output sound. As a result, there is a problem that no sound is emitted from the hearing aid and causes a failure of the earphone or the like.
そして、この音響ダンパは補聴器の使用者が交換することができないため、音響ダンパに液体状の耳垢や外耳道内に分泌される油などの液状物質が詰まる度に、補聴器販売店などに音響ダンパの交換を依頼しなければならず、手間と時間を要していた。 Since this acoustic damper cannot be replaced by a hearing aid user, every time the acoustic damper is clogged with liquid substances such as liquid earwax or oil secreted into the ear canal, I had to request an exchange, and it took time and effort.
本発明は、従来の技術が有するこのような問題点に鑑みてなされたものであり、その目的とするところは、液体状の耳垢や外耳道内に分泌される油などの液状物質が補聴器の内部に侵入するのを防止することができる液状物質の侵入防止構造を備えた補聴器を提供しようとするものである。 The present invention has been made in view of such problems of the prior art, and the object of the present invention is that liquid substances such as liquid earwax and oil secreted into the ear canal are contained inside the hearing aid. It is an object of the present invention to provide a hearing aid equipped with a liquid substance intrusion prevention structure that can prevent the intrusion into the body.
上記課題を解決すべく請求項１に係る発明は、補聴器の音口に、紙又は不織布製のフィルタからなる耳垢防止チップを設けたものである。 In order to solve the above-mentioned problems, the invention according to claim 1 is provided with an earwax prevention chip made of a filter made of paper or non-woven fabric at the sound opening of the hearing aid.
請求項２に係る発明は、請求項１記載の液状物質の侵入防止構造を備えた補聴器において、前記フィルタの中心部に孔を開けた。 According to a second aspect of the present invention, in the hearing aid having the liquid substance intrusion prevention structure according to the first aspect, a hole is formed in a central portion of the filter.
以上説明したように請求項１に係る発明によれば、紙又は不織布製のフィルタが液体状の耳垢や外耳道内に分泌される油などの液状物質を吸収するので、それらが補聴器の内部へ侵入するのを防止することができ、音響ダンパのメッシュ部が詰まる可能性が低くなる。 As described above, according to the first aspect of the invention, the paper or non-woven filter absorbs liquid substances such as liquid earwax and oil secreted into the ear canal, so that they penetrate into the hearing aid. The possibility of clogging the mesh portion of the acoustic damper is reduced.
請求項２に係る発明によれば、紙又は不織布製のフィルタが液体状の耳垢や外耳道内に分泌される油などの液状物質を吸収して詰まった場合でも、孔より音を出すことができる。 According to the invention of claim 2, even when a filter made of paper or non-woven fabric absorbs a liquid substance such as liquid earwax or oil secreted into the ear canal, it can make a sound from the hole. .
以下に本発明の実施の形態を添付図面に基づいて説明する。ここで、図１は本発明に係る液状物質の侵入防止構造を備えた補聴器の斜視図、図２は同じく断面図である。なお、図１及び図２は補聴器の一部を表している。 Embodiments of the present invention will be described below with reference to the accompanying drawings. Here, FIG. 1 is a perspective view of a hearing aid provided with a liquid substance intrusion prevention structure according to the present invention, and FIG. 2 is a sectional view of the same. 1 and 2 show a part of the hearing aid.
本発明に係る液状物質の侵入防止構造を備えた補聴器は、図１及び図２に示すように、耳あな形補聴器１を構成するシェル部材２の端部に音口としての開口部３を開け、開口部３に筒部材４を嵌合させ、筒部材４に着脱自在な耳垢防止チップ５を装着している。なお、６はイヤホン、７はイヤホンチューブ、８は音響ダンパである。 As shown in FIGS. 1 and 2, the hearing aid equipped with the liquid substance intrusion prevention structure according to the present invention opens an opening 3 as a sound opening at the end of the shell member 2 constituting the ear-shaped hearing aid 1. The cylindrical member 4 is fitted into the opening 3, and a removable earwax prevention chip 5 is attached to the cylindrical member 4. In addition, 6 is an earphone, 7 is an earphone tube, and 8 is an acoustic damper.
耳垢防止チップ５は、円筒状のチップ本体１０と、チップ本体１０の開口部を塞ぐようにチップ本体１０のほぼ真中に張設されたフィルタ１１からなる。フィルタ１１は、液体状の耳垢や外耳道内に分泌される油などの液状物質の吸収に優れた紙又は不織布で形成されている。また、フィルタ１１の中心部には、孔１１ａが開けられている。 The earwax prevention chip 5 includes a cylindrical chip body 10 and a filter 11 stretched almost in the middle of the chip body 10 so as to close the opening of the chip body 10. The filter 11 is made of paper or nonwoven fabric excellent in absorption of liquid substances such as liquid earwax and oil secreted into the ear canal. Further, a hole 11 a is formed in the center of the filter 11.
以上のように構成された本発明に係る液状物質の侵入防止構造を備えた補聴器の作用について説明する。
装用者が耳あな形補聴器１を外耳道に挿入する際又は装用中に、液体状の耳垢や外耳道内に分泌される油などの液状物質が耳垢防止チップ５に侵入すると、液状物質は紙又は不織布製のフィルタ１１に吸収される。
The operation of the hearing aid having the liquid substance intrusion prevention structure according to the present invention configured as described above will be described.
When the wearer inserts the ear-shaped hearing aid 1 into the ear canal or during wearing, when a liquid substance such as liquid earwax or oil secreted into the ear canal enters the earwax prevention chip 5, the liquid substance is paper or non-woven fabric. It is absorbed by the filter 11 made of metal.
従って、液体状の耳垢や外耳道内に分泌される油などの液状物質が、フィルタ１１を通過してイヤホンチューブ７内に設けられた音響ダンパ８のメッシュ部に到達することはない。 Therefore, liquid substances such as liquid earwax and oil secreted into the ear canal do not pass through the filter 11 and reach the mesh portion of the acoustic damper 8 provided in the earphone tube 7.
更に、液体状の耳垢や外耳道内に分泌される油などの液状物質がフィルタ１１に吸収され、フィルタ１１が目詰まりしたとしても、フィルタ１１の中心部に孔１１ａが開けられているので、イヤホン６が出す音は孔１１ａを通って外耳道に至るため、耳あな形補聴器１としての機能を損なうことはない。 Furthermore, even if liquid substances such as liquid earwax and oil secreted into the ear canal are absorbed by the filter 11 and the filter 11 is clogged, the hole 11a is formed in the center of the filter 11, so the earphone Since the sound produced by 6 reaches the external auditory canal through the hole 11a, the function as the ear-shaped hearing aid 1 is not impaired.
また、耳垢防止チップ５は交換可能であるから、フィルタ１１が目詰まりした場合には、補聴器販売店などに交換を依頼することなく、使用者自身で交換することができる。 Further, since the earwax prevention chip 5 is replaceable, when the filter 11 is clogged, it can be replaced by the user himself without requesting replacement at a hearing aid store or the like.
本発明によれば、液体状の耳垢や外耳道内に分泌される油などの液状物質が耳垢防止チップに侵入しても、液状物質は紙又は不織布製のフィルタに吸収されるので、液状物質が補聴器の内部に侵入するのを防止することができ、補聴器販売店などに音響ダンパの交換を依頼する必要がなくなり、補聴器の使い勝手がよくなって補聴器の普及が図られる。 According to the present invention, even if a liquid substance such as liquid earwax or oil secreted into the ear canal enters the earwax prevention chip, the liquid substance is absorbed by the filter made of paper or non-woven fabric. It is possible to prevent the inside of the hearing aid from entering, and it is not necessary to request the replacement of the acoustic damper from a hearing aid store or the like, and the usability of the hearing aid is improved and the hearing aid is spread.
