Abstract
Description
本発明は、外耳道を密閉することなく装用することができる既製耳あな型補聴器に関する。 The present invention relates to an off-the-shelf hearing aid that can be worn without sealing the ear canal.
既製耳あな型補聴器は、装用者の耳型からケース本体を製作するオーダーメード耳あな型補聴器とは異なり、特定の形状でケース本体などを製作する耳あな型補聴器である。この既製耳あな型補聴器は、ケース本体とそのケース本体から外耳道に挿入する挿入部が設けられており、挿入部の先端には傘部を有した耳栓が取付けられている。装用時には、既製耳あな型補聴器自体を、この耳栓で保持することになり、耳栓の傘部と外耳道の内壁とは、全周にわたって接触することになる。このため、圧迫感や違和感などが生じる。また、外耳道内は密閉されるので、こもり感もある。 An off-the-shelf hearing aid is an ear-shaped hearing aid that produces a case body or the like in a specific shape, unlike a custom-made ear hearing aid that produces a case body from a wearer's ear shape. This off-the-shelf hearing aid is provided with a case main body and an insertion portion for insertion into the external auditory canal from the case main body, and an earplug having an umbrella portion is attached to the distal end of the insertion portion. At the time of wearing, the earplug type hearing aid itself is held by the earplug, and the umbrella portion of the earplug and the inner wall of the ear canal are in contact with each other over the entire circumference. For this reason, a feeling of oppression, a sense of incongruity, etc. arise. Moreover, since the inside of the external auditory canal is sealed, there is also a feeling of being crowded.
耳栓の中には、耳かけ型補聴器で使用しているように、耳栓の傘部に開口を設けたオープンタイプのものがあり、外耳道内を密閉しないで、こもり感、圧迫感や違和感などを大幅に軽減したものがある。しかし、オープンタイプの耳栓は、耳栓の傘部に開口を設けるので柔らかく、使用者の動きなどにより、既製耳あな型補聴器が振られて保持しきれない。 Some earplugs, like those used in ear-type hearing aids, have an open type with an opening in the earplug umbrella, and do not seal the outer ear canal. There is something that has greatly reduced. However, the open-type earplug is soft because an opening is provided in the umbrella portion of the earplug, and the ready-made earphone type hearing aid cannot be held due to the movement of the user.
また、特許文献１に記載のように、補聴器本体の音声出力孔の側に、耳穴に装着する耳穴装着部を有する補聴器であって、この耳穴装着部の基端部の周縁に取り付けた、伸縮性及び柔軟性のあるリング状クッションと、このリング状クッションの一端を固定するように、前記耳穴装着部の先端部の周縁に取り付けた、伸縮性及び柔軟性のあるイヤチップとを有するものが知られている。 In addition, as described in Patent Document 1, a hearing aid having an ear hole attachment part to be attached to the ear hole on the side of the sound output hole of the hearing aid main body, and attached to the periphery of the base end part of the ear hole attachment part. And a ring-shaped cushion having flexibility and flexibility, and an eartip having elasticity and flexibility attached to the periphery of the tip of the ear hole mounting portion so as to fix one end of the ring-shaped cushion. It has been.
しかし、特許文献１に記載の補聴器においては、伸縮性及び柔軟性の部材を用いたリング状クッションを設け、外耳道の内壁の全周にわたり密着性がよいので、こもり感、圧迫感や違和感などがあると共に、装着時間が長くなると、痛みやかゆいなどを感じることが推測される。 However, the hearing aid described in Patent Document 1 is provided with a ring-shaped cushion using a stretchable and flexible member, and has good adhesion over the entire circumference of the inner wall of the ear canal. At the same time, it is presumed that when wearing time is prolonged, pain or itching is felt.
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、外耳道を密閉することなく、装着時のこもり感をなくし、圧迫感や違和感などを低減する既製耳あな型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 to seal the external auditory canal, eliminate the feeling of bulkiness when worn, and feel a sense of pressure or discomfort. It is an object of the present invention to provide an off-the-shelf hearing aid.
