Description

Translated fromJapanese

【0001】
【発明の属する技術分野】
本発明は、歯科治療の際に使用する治療補助具に関するものであり、特に、歯の治療時に長時間口を開けていることへの患者の負担を軽減するための口腔開口補助具に関するものである。
【0002】
【従来の技術】
歯科治療を行う際には、患者自身が口を開けなければならない。治療をより円滑に行うためには、医師が口腔内の視野を十分に確保する必要があるため、患者はより大きく口をあける必要がある。しかし、長時間口を開けておくことは、患者にとって非常に苦痛であり、治療中に徐々に口が閉じていってしまったり、また、小さい子供等は治療中に突然口を閉じてしまう危険性があり、治療に支障をきたしてしまうことはもちろんのこと、患者の口腔内外が治療器具により傷つけられてしまう恐れがある。
【0003】
従来より口腔開口補助具は数多く提案されており、上顎歯と下顎歯との間に介在させる介在部材を患者の口の中に入れ、患者の口を大きく開いた後に、ネジ止め等で開口状態を維持するもの(実開昭62−1606、実開平3−67612、実用新案登録第3033529号、特許第2617881号)に関しては、補助具自体が複雑な構造となるため、製造コストが高価であること、さらに、重量のある補助具を口の中に長時間入れておくことが患者の負担となること等の問題があった。また、弾力性を保有する部材をリング状及び略U字状に形成し、それを患者の口の中に入れることで開口状態を維持する、構造が比較的単純なもの(実開昭61−196724、実開平1−69510、特開2002−65705)に関しては、補助具を口の中に挿入及び取り出す際に無理が生じてしまい、口腔内外を傷つけてしまう等の患者に負担が掛かる問題があった。
【0004】
【発明が解決しようとする課題】
そこで本発明は、前記事情に基づいてなされたものであり、歯科治療において、患者に苦痛を与えることなく長時間開口状態を保つことが可能で、口の中への取付け及び口の中からの取外しが患者に負担を掛けずに容易且つ安定に行え、さらに医師の治療を妨げることのない安全な口腔開口補助具を提供することを目的とする。
【0005】
【課題を解決するための手段】
上記目的を達成するために、本発明のうち請求項1記載の発明は、口腔内に挿入し且つ上顎と下顎に介在させて開口状態を維持するための前後に屈曲可能な支持板と、該支持板の起立状態を保つための保持部材と、から構成してあることを特徴とする。
【0006】
このように構成すれば、支持板が屈曲することで、口の中への補助具の挿入及び口の中から補助具の取り出しが容易且つスムーズに行うことが可能となり、口腔内への補助具の取付け及び取外しを患者に負担を掛けることなく行うことができ、また、その際に口腔内外を補助具で傷つけることを防ぐことができる。また、保持部材により支持板の起立状態を保つことが可能であり、口腔内の開口状態を確実に維持することができるため、長時間開口状態を維持する患者の苦痛を和らげることができる。さらに、保持部材によって口腔内で起立状態を保った支持板に、舌を置き固定しておくことが可能であるため、舌の押圧で支持部材の起立状態をより一層確実に保つことができるとともに、舌が治療の妨げになることを防ぐことが可能となり、安全に治療が行え、患者に対しても治療中に安心感を与えることができる。支持板に関しては、屈曲可能に構成してあれば特に問わず、例えば、一枚の板材で屈曲可能に構成してもよいし、2枚の板材を屈曲可能に連結させてもよい。
【0007】
また、請求項2記載の発明のように、支持板に保持部材を固定するためのストッパー部を形成することによって、保持部材を確実且つ強固に支持板に固定することが可能となり、口腔内の開口状態をより一層確実に保つことができるため、治療中に支持板の起立状態が緩むことによる治療の妨げを防ぎ、治療中における患者の負担をより一層軽減することができるとともに、治療もより一層安全且つスムーズに行うことができる。ストッパー部に関しては、特に問わないが、例えば凸部形成、切り込み、ストッパー部材の取付等が挙げられる。
【0008】
請求項3記載の発明のように、支持板の上下両端に緩衝部材を備えることによって、上顎及び下顎と補助具の接触部分の痛みを和らげることが可能となり、治療中における患者の負担をより一層軽減することができる。緩衝部材に関しては、シリコンゴムやゴム等の軟質樹脂が望ましい。
【0009】
また、請求項4記載の発明のように、支持板の上下両端の形状を上顎及び下顎の形状に合わせ、上端部分が上向き略コの字状、下端部分は中央部が窪んだ形状にすることによって、上顎及び下顎と補助具の接触部分の痛みをより一層和らげることが可能であることはもちろんのこと、支持板の上下両端を上顎及び下顎に密着させることが可能となり、支持板の固定がより一層強固化され、口腔内の開口状態を確実に保つことができるとともに、患者の負担もより一層軽減することができる。
【0010】
補助具の材質に関しては、特に問わないが、請求項5記載の発明のように、補助具の材質を硬質紙又は樹脂にすることによって、補助具の一体形成が行える等補助具の形成が容易となり低コスト化を図ることができるため、使い捨てが可能となり非常に衛生的である。また、材質的にリサイクルが可能であるため非常にコストメリットがある。さらに、補助具が軽量となるため、長時間口の中に補助具を入れておくことへの患者の負担をより一層軽減することができる。補助具を硬質紙で形成する場合は、緩衝部材をシリコンゴムやゴム等の軟質樹脂にすることもできるが、支持板の上下両端に細かな切り込みを入れ、柔らかくすることで緩衝部材にすることもできる。また、樹脂で形成する場合は、シリコンゴムやゴム等の軟質樹脂を後付けにすることもできるし、二重形成により補助具と一体化することも可能である。
【0011】
【発明の実施の形態】
以下、本発明の実施形態の一例を図面に基づいて説明する。
【0012】
本発明の口腔開口補助具1は、図1、図2に示すように、1枚のプラスチックの板体によって一体形成し、支持板2には前後に屈曲可能なように支持板2の短手方向に折り目3aを形成し、屈曲部分4より上方の支持板2の左右両側には保持羽根5を形成し、保持羽根5が前後に屈曲可能なように支持板2との境目に折り目3bが形成してある。支持板2の屈曲部分4の下方には、補助具1を組み立てた際に保持羽根5を固定するための、四角形の凹形状(図面ではその反対側が示されているため凸形状となっている)をしたストッパー6が2箇所形成してある。支持板2の上下両端7a、7bの形状は上顎8a及び下顎8bの形状に合わせて、上端部分7aは上向き略コの字状、下端部分7bは中央部が窪んだ形状をしている。また、支持板2の上下両端7a、7bには、補助具1と上顎8a及び下顎8bの接触部分の苦痛を和らげるためにシリコンゴム9が固着してある。
【0013】
このように、補助具1を一体形成し、支持板2の屈曲部分4と、支持板2と保持羽根5の境目に折り目3a、3bを形成することで、指10a、10bで保持羽根5を後方側に折り曲げ、保持羽根5の下端部分がストッパー6に固定される位置まで支持板2を後方側に屈曲させることで、補助具1が容易に組み立てられることが可能であるため、口腔内への補助具1の取付け及び口腔内からの取外しがスムーズに行うことができる。ここで、折り目3a、3bの形状としては、例えば切り込み、凸部のみ又は凹部凸部の組み合わせ等が挙げられる。支持板2の屈曲角度は保持羽根5の下方部分の形状で決定される。また、保持羽根5が支持板2の左右両側に形成されているため、補助具1を口腔内に取付けた際に、舌11を左右両側の保持羽根5の中間に置くことが可能となるため、左右の保持羽根5によって治療中に舌11が補助具1からズレることを防ぎ、確実に固定することができ、治療の妨げになることを防ぐことができる。
【0014】
次に、上記口腔開口補助具1の口腔内への取付け及び口腔外への取外し方法について説明する。
【0015】
補助具1を口腔内に取付け開口状態を維持する場合は、まず、図3(a)に示すように、口の中に挿入する補助具1のストッパー6の凸部が手前且つ下側になっているかを確認する。次に、図3(b)に示すように、親指10aと人差し指10bで左右の各保持羽根5を後方側に折り曲げる。そして、図3(c)に示すように、支持板2の下方を指10cで手前側(矢印)に押して、図3(d)に示すような状態まで折り曲げた後、患者に口を大きく開いてもらい口の中(矢印)に挿入する。支持板2の上下両端7a、7bと口腔内の上顎8a及び下顎8bの固定箇所と固定具合を確認し、図3(e)に示すように、保持羽根5を折り曲げたままの状態でゆっくりと手前側(矢印)に引くことで、保持羽根5がストッパー6の凹部に嵌り、口腔内での支持板2の起立状態が保持され、開口状態を維持することができる。このように補助具1を口腔内に取付ければ、口腔内外に無理が掛からないため傷を付けることもなく、また、作業を容易且つスムーズに行えるため、患者の負担を軽減させることができる。
【0016】
補助具1を口腔内から取外す場合は、図3(f)に示すように、支持板2の屈曲部分4を指10cで後方側(矢印)に押した後、取付け方法と逆の順序で丁寧にゆっくりと作業を行えば、口腔内外に無理を掛けずに傷を付けることもなく、容易且つスムーズに口の中から補助具1を取外すことができる。
【0017】
図4(a)、(b)は、補助具1を実際に口腔内に取付けた状態を示したもので、補助具1は、歯茎の奥の部分の上顎8a及び下顎8bに取付け固定し、また、補助具1に舌11を置き固定するため、補助具1及び舌11が歯のどの箇所の治療にも妨げになることを防ぐことが可能で、治療がスムーズに行えるとともに、患者に安心感を与えることができる。
【0018】
尚、支持板2の上部に膨出部12を形成することによって、上顎8aと補助具1の接触面積を広げることが可能であり、補助具1を口腔内に取付けた時の痛みを和らげ、装着感をより一層快適にすることができる。また、支持板2の上方に目印13を付けることで、補助具1の表裏及び上下が瞬時に判断することができる。
【0019】
【発明の効果】
本発明のうち請求項1記載の発明によれば、補助具によって口腔内の開口状態を確実に維持することが可能であり、長時間開口状態を維持する患者の苦痛を和らげることができるとともに、口腔内への補助具の取付け及び取外しが容易且つスムーズに行うことが可能であるため、口腔内外に無理が掛からず患者に負担を掛けることを防ぐことができる。また、補助具に舌を固定しておくことが可能であるため、治療が安全且つスムーズに行え、患者にも治療中に安心感を与えることができる非常に優れた口腔開口補助具を提供することができる。
【0020】
本発明のうち請求項2記載の発明によれば、保持部材を確実且つ強固に支持板に固定することが可能となり、口腔内の開口状態をより一層確実に保つことができるため、治療中における患者の負担をより一層軽減することができるとともに、治療もより一層スムーズに行うことができる。

[0002]
[Prior art]
When performing dental treatment, the patient must open his mouth. In order for the treatment to be performed more smoothly, the physician needs to ensure a sufficient visual field in the oral cavity, so the patient needs to open the mouth more widely. However, keeping the mouth open for a long time is very painful for the patient, and the mouth may gradually close during the treatment, and small children may suddenly close the mouth during the treatment. There is a danger that the treatment may be hindered and that the inside and outside of the patient's mouth may be damaged by the treatment device.
[0003]
Conventionally, many mouth opening assisting devices have been proposed. An intervening member to be interposed between the upper and lower teeth is inserted into the patient's mouth, and after the patient's mouth is greatly opened, the opening state is tightened with a screw or the like. (Japanese Utility Model Application Laid-Open No. 62-1606, Japanese Utility Model Application Laid-Open No. 3-67612, Utility Model Registration No. 3033529, and Japanese Patent No. 2617881), the manufacturing cost is high because the auxiliary tool itself has a complicated structure. In addition, there is a problem in that putting a heavy assisting tool in the mouth for a long time puts a burden on the patient. In addition, a member having elasticity is formed in a ring shape and a substantially U-shape, and is kept in an open state by being inserted into a patient's mouth. 196724, Japanese Utility Model Laid-Open No. 1-69510, and Japanese Patent Application Laid-Open No. 2002-65705), there is a problem in that when the auxiliary tool is inserted into and taken out of the mouth, excessive effort is caused and the patient is injured inside and outside the oral cavity. there were.
[0004]
[Problems to be solved by the invention]
Therefore, the present invention has been made based on the above circumstances, and in a dental treatment, it is possible to maintain an open state for a long time without causing pain to a patient, and it is possible to attach the patient to the mouth and to remove the patient from the mouth. An object of the present invention is to provide a safe oral opening aid that can be easily and stably removed without imposing a burden on a patient and that does not hinder treatment by a doctor.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the invention according toclaim 1 of the present invention includes a support plate that can be bent back and forth to be inserted into an oral cavity and interposed between an upper jaw and a lower jaw to maintain an open state; And a holding member for keeping the support plate in an upright state.
[0006]
With this configuration, the support plate is bent, so that the insertion of the assisting tool into the mouth and the removal of the assisting tool from the mouth can be performed easily and smoothly, and the assisting tool can be inserted into the oral cavity. Can be attached and detached without putting a burden on the patient, and at this time, it is possible to prevent the inside and outside of the oral cavity from being damaged by the aid. In addition, the support member can keep the standing state of the support plate, and the opening state in the oral cavity can be reliably maintained, so that the pain of the patient who maintains the opening state for a long time can be eased. Furthermore, since the tongue can be placed and fixed on the support plate that has been kept upright in the oral cavity by the holding member, the upright state of the support member can be more reliably maintained by pressing the tongue. In addition, it is possible to prevent the tongue from hindering the treatment, perform the treatment safely, and give the patient a sense of security during the treatment. The support plate is not particularly limited as long as it is configured to be bendable. For example, the support plate may be configured to be bendable by a single plate member, or two plate members may be connected to bendable.
[0007]
Further, by forming the stopper portion for fixing the holding member to the support plate as in the invention according toclaim 2, it becomes possible to securely and firmly fix the holding member to the support plate, and the Since the open state can be maintained more reliably, it is possible to prevent the obstruction of the treatment due to the loosened upright state of the support plate during the treatment, thereby further reducing the burden on the patient during the treatment and improving the treatment. It can be performed more safely and smoothly. The stopper portion is not particularly limited, but examples include formation of a convex portion, cutting, mounting of a stopper member, and the like.
[0008]
By providing the cushioning members at the upper and lower ends of the support plate as in the invention according toclaim 3, it is possible to reduce the pain at the contact portions between the upper and lower jaws and the assisting device, and to further reduce the burden on the patient during treatment. Can be reduced. As for the cushioning member, a soft resin such as silicone rubber or rubber is desirable.
[0009]
Further, as in the invention according toclaim 4, the shape of the upper and lower ends of the support plate is adjusted to the shape of the upper jaw and the lower jaw, and the upper end portion has an upward substantially U-shape, and the lower end portion has a concave central portion. This not only makes it possible to further alleviate the pain at the contact between the upper and lower jaws and the assistive device, but also allows the upper and lower ends of the support plate to be in close contact with the upper and lower jaws, thus securing the support plate. It is further strengthened, the opening state in the oral cavity can be reliably maintained, and the burden on the patient can be further reduced.
[0010]
The material of the assisting tool is not particularly limited, but the assisting tool can be formed easily by using hard paper or resin for the assisting tool, as in the fifth aspect of the invention. Therefore, the cost can be reduced, so that it is disposable and very hygienic. In addition, since the material can be recycled, there is a great cost advantage. Further, since the weight of the assisting device is reduced, the burden on the patient for keeping the assisting device in the mouth for a long time can be further reduced. When the auxiliary tool is made of hard paper, the cushioning member can be made of a soft resin such as silicone rubber or rubber.However, fine cuts are made at the upper and lower ends of the support plate, and the cushioning member is made softer. You can also. In the case of forming with resin, a soft resin such as silicone rubber or rubber can be retrofitted, or it can be integrated with the auxiliary tool by double forming.
