Description

【０００１】
【産業上の利用分野】
本発明は、歯科医療用唾液吸引具に関するものである。
【０００２】
【従来の技術】
歯科医療においては、治療中に口腔内に生じる唾液や汚水を吸引排出するとともに、治療部位の歯牙から舌や頬粘膜等を隔離する必要がある。このため従来は、歯科用ユニットのフレキシブルアームに取り付けたバキュームチップを用いて行ったり、アシスタントや衛生士が歯科用バキュームチップを用いて行っていた。
【０００３】
【発明が解決しようとする課題】
しかしながら、口腔内におけるバキュームチップの固定性や安定性が悪いため、歯科治療中に予期せぬ動きをする舌等の口腔内器官を、確実に治療部位の歯牙から隔離させておくことはできなかった。また、歯科医師の治療に応じて、バキュームチップを操作することは、アシスタントや衛生士にとって極めて熟練を要する作業であった。本発明は上記に鑑みてなされたものであり、口腔内に装着するだけで唾液や汚水を吸引排出するとともに、治療部位の歯牙から舌や頬粘膜等を隔離できる歯科医療用唾液吸引具を提供することを目的とする。

【００２５】
請求項７に記載された本発明の歯科医療用唾液吸引具は、保形用の線材にニッケル・チタン合金線材を用いたもので、該ニッケル・チタン合金線材は成分比と焼鈍条件により使用温度領域において、超弾性特性、加工硬化型特性及び形状記憶特性等の好ましい特性を付与できる。従って、これらの特性を単独又は組み合わせて用いることにより、優れた使い勝手や装着性をもたらすことができる。
【００２６】
請求項８に記載された本発明の歯科医療用唾液吸引具は、係止部位で露出するＵ字形に屈曲した保形用の線材を、上顎歯若しくは下顎歯の何れかに係止して口腔内に装着するようにしたから、係止部を容易かつ確実に係止できる。
【００２７】
請求項９に記載された本発明の歯科医療用唾液吸引具は、前記保形用の線材の露出部を軟質部材により被覆したから、露出した線材が直接上顎歯若しくは下顎歯に接触することがなく、装着時の患者の違和感を軽減できる。
【００２８】
請求項１０に記載された本発明の歯科医療用唾液吸引具は、上記請求項１に記載の歯科医療用唾液吸引具と同様の作用効果を奏することができるとともに、可撓性及び保形性を有するパイプ材を用いて形成したものであり、前方帰還部の前端に形成した吸引連結部に吸引パイプを連結して用いる。パイプ内部に保形用の線材を有しないから、製作が容易であるとともに、洗浄や消毒が簡単にできる。
【００２９】
請求項１１に記載された本発明の歯科医療用唾液吸引具は、前方帰還部の何れか一方の前端を封止して、何れか他方の前端に前記吸引用連結部を形成したもので、口腔外へ延びる吸引連結部、又は吸引用連結部に連結する吸引パイプが何れか一方のみとなるから、装着時の患者の違和感を軽減することができる。
【００３０】

【００３１】
請求項１３に記載された本発明の歯科医療用唾液吸引具は、前方帰還部の何れか一方の前端部に屈曲部を形成して、上顎歯若しくは下顎歯の何れかを跨がせるとともに、前方帰還部の何れか他方に吸引可能に連結したものであり、口腔外へ延びる吸引連結部、又は吸引用連結部に連結する吸引パイプが何れか一方のみとなるから、装着時患者の違和感を軽減することができる。また、屈曲部を上顎歯若しくは下顎歯の何れかを跨がせているから、係止部とこの屈曲部とにより上顎歯と下顎歯の双方に係止することができ、口腔内で位置がずれることがない確実な装着を施こすことができる。
【００３２】
請求項１４に記載された本発明の歯科医療用唾液吸引具は、前方帰還部若しくは奥行き部の何れかに咽喉部を塞ぐネット若しくはスクリーンを設けたから、治療中に誤って治療用小器具等が口腔内に外れ落ちても、飲み込んでしまうことがない。
【００３３】
請求項１５に記載された本発明の歯科医療用唾液吸引具は、片側若しくは両側の奥行き部と前方帰還部間に、口腔内器官を隔離する隔離部材を差し渡したから、治療を施こす歯牙部分に舌や頬粘膜の口腔内器官が近づくことを防止できる。
【００３４】
【発明の実施の形態】
本発明の実施の形態を添付図面を参照して説明する。図１は、本発明に係る歯科医療用唾液吸引具（以下単に吸引具という）１の斜視図である。この吸引具１は、軟質のゴム、合成樹脂若しくは高分子樹脂製の１本のチューブ２内に保形用の線材３を挿入して屈曲及び曲成することにより形成される。先ず、チューブ２の略中央部を二つ折状に屈曲して略Ｕ字形の係止部４が形成される。そして、該係止部４から略平行に連続させるとともに、上方に向かって膨らむように緩やかに湾曲させた２列の奥行き部５と、該奥行き部５と略同じ曲率で湾曲させた２列の湾曲連続部６と、該湾曲連続部６に続けて、下方に向かって膨らむように緩やかに湾曲させた２列の前方帰還部７とが順次曲成される。チューブ２内の保形用の線材３は、該前方帰還部７まで挿入されていて、上記各部を保形している。前方帰還部７に続くチューブ２には、吸引用連結部８が形成され、その吸引用連結部８の二つの端部を合わせて連結する吸引用連結管９が接続されている。また、上記奥行き部５及び前方帰還部７には、所定の間隔を置いて複数個の唾液吸引孔１０が形成されている。
【００３５】
尚、上記吸引具1は、予め各部を屈曲成形した保形用の線材３の一端部から、チューブ２を挿し通すことによっても形成できる。また、保形用の線材３は、チューブ２の製造時に一体にインサートしたものであってもよい。さらに、チューブ２の外周面の形状は、円形の外に四角形、楕円形等任意の形状とすることができる。
【００３６】
上記吸引具１は図２に示すように、係止部４を上顎歯２１の何れかに係止して開口した口腔２２内に装着したとき、略平行な２列の奥行き部５が上顎堤２３の両側に沿って口腔奥部に向かう。このとき、患者の頬側の奥行き部５の頂部５ａは、齦頬移行部（頬粘膜と歯肉の境界部）付近に位置し、舌側の奥行き部５の頂部５ｂは、口蓋と歯肉の境界部付近に位置する。そして、奥行き部５に連続する２列の湾曲連続部６は、上顎堤２３に対向する下顎堤２４の奥部両側に向かって略平行に下がっている。湾曲連続部６に連続する２列の前方帰還部７は、下顎堤２４の両側に沿って口腔の外方に向かう。このとき、患者の頬側の前方帰還部７の最低部７ａは、齦頬移行部に位置し、舌側の前方帰還部７の最低部７ｂは、口腔底と歯肉の境界部に位置する。下唇２５を越えて口腔２２外に導き出された頬側の吸引用連結部８と、下顎前歯２６を乗り越えて口腔２２外に導き出された舌側の吸引用連結部８の端部を連結した吸引用連結管９には、吸引チューブ２７を介してバキュームポンプ２８が接続されている。
【００３７】
上記したように開口した口腔２２内に吸引具１を装着して、バキュームポンプ２８をオンすると、吸引具１内が負圧になって奥行き部５及び前方帰還部７に設けた複数の唾液吸引孔１０から、歯科治療中に顎下腺、耳下腺及び舌下腺から生じる唾液や、治療中に生じる口腔内の汚水及び歯牙切削時に回転切削具２９の使用で注水される冷却水を確実に吸引排出できる。このとき、患者の舌３０や頬粘膜の口腔内器官が、奥行き部５、湾曲連続部６及び前方帰還部７に妨げられて、治療を施こす歯牙部分に近づかないように隔離できる。従って、治療の邪魔にならないばかりでなく、予期せぬ動きを生じる患者の舌３０が、回転切削具２９等に触れて傷付くようなこともない。また、口腔２２内では、２列の湾曲連続部６により、各奥行き部５と各前方帰還部７とがそれぞれ上下で対向して、開口状態の上下の歯牙若しくは顎堤を該奥行き部５と前方帰還部７で保持して安定させることができるから、治療のため患者が開口状態を維持する際の疲労を軽減することができる。さらに、唾液吸引のためのアシスタントを必要とすることなく歯料医師１人で治療が可能となる。
尚、バキュームポンプを用いない吸引排出装置を使用してもよい。
【００３８】
また、上記吸引具１は、係止部４を下顎歯の何れかに係止して、奥行き部５を下顎堤２４の両側に、前方帰還部７を上顎堤２３の両側とする天地を逆にした装着形態とすることもできる。そして、上顎堤２３に沿う奥行き部５若しくは前方帰還部７に、唾液吸引孔１０を設けないで、下顎堤２４に沿う奥行き部５若しくは前方帰還部７の唾液吸引孔１０から、下顎堤２４の付近に溜まる唾液や、治療中に生じる口腔内の汚水等を吸引排出するようにしてもよい。
【００３９】
本発明の吸引具１は、前方帰還部７だけ若しくは奥行き部５及び前方帰還部７の両方を湾曲しない直線形状にすることも、湾曲連続部６を直線状の連続部６ａとすることもできる（図３（ａ），（ｂ））。さらに、図４に示すように、直線状の奥行き部５と前方帰還部７を連続させて、唾液吸引孔１０を全体に亙って形成することもできる。
【００４０】
また、図５に示すように奥行き部５から前方帰還部７に至る湾曲連続部６のチューブ２内の位置に、保形用の線材３を巻回したコイル状部３ａを設けて可撓性を付与することもできる。これにより、該コイル状部３ａを撓ませて、図６に示すように奥行き都５と前方帰還部７とを互いに接近離間させることができ、口腔２２内への装着及び取り外しが容易にできる。また、巻径やコイルピッチ等を変化させて撓み力を調整することが可能となり、装着したときに作用する撓み反力により、治療のため患者が開口状態を維持する際の疲労を軽減することができる。
【００４１】
さらに、保形用の線材３として、全長に亙って小径のコイル状に巻回したものや、ピアノ線等の弾力性を有する線材を用いることにより、奥行き部５と前方帰還部７とが互いに接近離間するように大きく撓ませることができる。これにより、上記と同様な利点を生じさせることが可能になる。
【００４２】
図７に示す吸引具３１は、係止部３４でチューブ３２を切断して、略Ｕ字形に屈曲成形した保形用の線材３３を露出させ、上顎歯の何れかに係止するようにするとともに、チューブ３２の両切断端部３２ａを気密に封止したものである。露出した略Ｕ字形に屈曲した保形用の線材３３により、容易かつ確実に上顎歯２１の何れかに係止することができる。さらに、図８に示すように、保形用の線材３３が露出した係止部３４ａにゴムや合成樹脂等の軟質部材３５を被覆して、係止する際金属線が直接歯牙に当たる際の違和感を軽減することができる。その他、保形用の線材３に被覆線材を用いることもできる。
【００４３】
また、保形用の線材３の所定部位毎に可撓性を異ならせて、歯科医師が患者の口腔部の大小や歯並び等に応じて吸引具１，３１の形状を変化させて、装着性を高めることができる。構造的に弾力性を異ならせるには、所定部位を延伸加工などで線材径を変えたり、細い線材の外周にパイプを嵌めてかしめたりねじ込んで接続したり、或いはろう付け加工等を施して補強したりすることで弾力性を異ならせることが可能となる。さらに、保形用の線材の所定部位を合成樹脂製の線材により代用することもできる。又、金属線を用いる場合、予め所定部位を通電加熱急冷等の熱処理を施すことで弾力性を他の部位と異ならせることができる。
【００４４】
保形用の線材３にステンレス合金線材を用いて、所定部位毎に可撓性を異ならせることもできる。例えば、オーステナイト組織のステンレス鋼は、塑性加工によって一部マルテンサイト組織に変態し硬くなる。また、約１１００℃まで加熱し急冷する固溶化処理を施こすと、全体が完全なオーステナイト組織となり、極めて柔らかくなる。従って、所定の部位に必要な可撓性を付与でき、吸引具１を歯科医師が患者の口腔部の大小や歯並び等に応じて変形させることができ、優れた装着性を実現することができる。そして、ステンレス合金線材は、保形用の線材３の特定の部位のみに用いることもできる。
【００４５】
保形用の線材３にニッケル・チタン合金線材を用いてもよい。ニッケル・チタン合金には、超弾性特性や加工硬化型特性、或いは形状記憶特性を示すものが知られている。これらの特性を単独又は組み合わせて用いることにより、優れた使い勝手や装着性を実現できる。ニッケル・チタン合金線材はその組成比にもよるが、３５０℃〜４００℃近傍で長時間熱処理することにより超弾性特性を示すが、短時間の熱処理では加工硬化特性を示す。従って、熱処理条件や線径を調整することにより、簡単に弾力性を変化させることができる。従って、保形用の線材３の特に奥行き部５及び前方帰還部７に相当する部位を、固溶化処理などの熱処理により柔軟にして、患者の上顎堤２３若しくは下顎堤２４の高さに合わせて吸引具１，３１を形作ることができるから、口腔内への装着がより確実となり、使い勝手が向上するとともに、装着時の患者の違和感を軽減することができる。尚ニッケル・チタン合金の他に、例えば形状記憶合金等の銅−アルミニウム−ニッケル系合金、銅−亜鉛−アルミニウム系合金等も保形用の線材に用いることができる。そして、該ニッケル・チタン合金線材等は、保形用の線材３の特定の部位のみに用いることもできる。
【００４６】
図９に示す吸引具４１は、可撓性及び保形用を有する金属製或いは高分子樹脂製パイプ４２を用いて、係止部４４、奥行き部４５、湾曲連続部４６、前方帰還部４７及び口腔内で終わる吸引用連結部４８を曲成するとともに、奥行き部４５及び前方帰還部４７に複数の唾液吸引孔５０を形成したものである。そして、吸引用連結部４８に、下唇２５や下顎前歯２６を乗り越える吸引用チューブ４９を連結する。この吸引具４１の作用は、図１に示す吸引具１に準じる。素材を可撓性を有する合成樹脂製とした場合は、ソフトな装着感を感得でき患者に違和感を与えることがない。また、金属製或いは合成樹脂製のパイプ４２内に保形用の線材を通していないから、洗浄、消毒等が容易となる。
【００４７】
上記吸引具４１も、奥行き部４５を下顎堤２４の両側に、前方帰還部４７を上顎堤２３の両側とする天地を逆にした装着形態とすることもできる。そして、上顎堤２３に沿う奥行き部４５若しくは前方帰還部４７に、唾液吸引孔５０を設けないで、下顎堤２４に沿う奥行き部４５若しくは前方帰還部４７の唾液吸引孔５０のみから、下顎堤２４部分に溜まる唾液や、治療中に生じる口腔内の汚水等を吸引排出するようにしてもよい。また、前記図３（ａ），（ｂ）で示したのと同様に、奥行き部４５及び前方帰還部４７の両方若しくは前方帰還部４７のみを湾曲しない直線形状にすることも、湾曲連続部４６を直線状の連続部とすることもできる。さらに、図４に示したのと同様に、直線状の奥行き部４５と前方帰還部４７を連続させた形状とすることもできる。その他、左右一対の吸引具１，３１，４１を、係止部どうし連結したり、吸引用連結部どうしを連結する等して、左右の上顎堤２１及び下顎堤２４に同時に装着して用いることもできる。
【００４８】

And it continued from the latching | locking part 4 substantially parallel, and was gently curved so that it might bulge upwards. Two rows Depth portion 5 and curved with substantially the same curvature as depth portion 5 Two rows The curved continuous portion 6 and the two rows of the front feedback portions 7 that are gently curved so as to bulge downward are sequentially bent following the curved continuous portion 6. The shape-retaining wire rod 3 in the tube 2 is inserted up to the front feedback portion 7 to retain the respective portions. A suction connecting portion 8 is formed on the tube 2 following the front feedback portion 7, and a suction connecting tube 9 that connects the two ends of the suction connecting portion 8 together is connected. In addition, a plurality of saliva suction holes 10 are formed in the depth portion 5 and the front feedback portion 7 at predetermined intervals.
[0035]
The suction tool 1 can also be formed by inserting a tube 2 from one end of a shape-retaining wire 3 in which each part is bent in advance. Further, the shape-retaining wire 3 may be integrally inserted when the tube 2 is manufactured. Furthermore, the shape of the outer peripheral surface of the tube 2 can be an arbitrary shape such as a rectangle or an ellipse in addition to a circle.
[0036]
As shown in FIG. 2, the suction tool 1 is substantially parallel when the locking portion 4 is locked to one of the upper teeth 21 and mounted in the opened oral cavity 22. Two rows The depth part 5 goes to the back of the oral cavity along both sides of the maxillary ridge 23. At this time, the top 5a of the depth part 5 on the cheek side of the patient is located near the cheek cheek transition part (buccal mucosa and the gingival boundary), and the top 5b of the lingual depth part 5 is the boundary between the palate and the gingiva. Located near the department. And it continues to the depth part 5 Two rows The curved continuous portion 6 is lowered substantially in parallel toward both sides of the inner portion of the lower jaw ridge 24 facing the upper jaw ridge 23. Continuation of the curved continuous part 6 Two rows The anterior feedback part 7 is directed outward of the oral cavity along both sides of the lower jaw ridge 24. At this time, the lowest part 7a of the front feedback part 7 on the cheek side of the patient is located at the cheek cheek transition part, and the lowest part 7b of the front feedback part 7 on the lingual side is located at the boundary between the oral cavity bottom and the gingiva. The buccal suction connection part 8 led out of the oral cavity 22 beyond the lower lip 25 and the end part of the lingual suction connection part 8 led out of the oral cavity 22 over the lower jaw front teeth 26 were connected. A vacuum pump 28 is connected to the suction connection pipe 9 via a suction tube 27.
[0037]
When the suction device 1 is mounted in the mouth 22 opened as described above and the vacuum pump 28 is turned on, the suction device 1 becomes negative pressure and a plurality of saliva suctions provided in the depth portion 5 and the front feedback portion 7 are sucked. From the hole 10, saliva generated from the submandibular gland, parotid gland and sublingual gland during dental treatment, sewage generated in the oral cavity during treatment, and cooling water injected by using the rotary cutting tool 29 during tooth cutting are ensured. Can be sucked and discharged. At this time, the patient's tongue 30 and the oral organs of the buccal mucosa are blocked by the depth portion 5, the curved continuous portion 6, and the front return portion 7, and can be isolated so as not to approach the tooth portion to be treated. Therefore, the patient's tongue 30 not only does not interfere with the treatment but also causes unexpected movements, and does not touch the rotary cutting tool 29 or the like. In the oral cavity 22, Due to the two rows of curved continuous portions 6, each depth portion 5 and each front feedback portion 7 face each other vertically, Open upper and lower teeth or jaw crest The depth part 5 and the front feedback part 7 Hold on To stabilize Because you can It is possible to reduce fatigue when the patient maintains an open state for treatment. Furthermore, for saliva suction One dental doctor can be treated without the need for an assistant.
A suction / discharge device that does not use a vacuum pump may be used.
[0038]
In addition, the suction tool 1 locks the locking portion 4 to any of the lower jaw teeth, and reverses the top and bottom with the depth portion 5 on both sides of the lower jaw ridge 24 and the front return portion 7 on both sides of the upper jaw ridge 23. It can also be set as the mounting form. Then, the saliva suction hole 10 is not provided in the depth portion 5 or the front return portion 7 along the maxillary ridge 23, and the saliva suction hole 10 of the depth portion 5 or the front return portion 7 along the lower jaw ridge 24 is used. Saliva collected in the vicinity, sewage in the oral cavity generated during treatment, and the like may be sucked and discharged.
[0039]
The suction tool 1 of the present invention may be configured so that only the front feedback portion 7 or both the depth portion 5 and the front feedback portion 7 are not curved. The curved continuous portion 6 can be a linear continuous portion 6a. (FIGS. 3A and 3B). Furthermore, as shown in FIG. 4, the saliva suction hole 10 can also be formed over the whole by making the linear depth part 5 and the front return part 7 continue.
[0040]
Further, as shown in FIG. 5, a coiled portion 3a around which a shape-preserving wire 3 is wound is provided at a position in the tube 2 of the curved continuous portion 6 extending from the depth portion 5 to the front feedback portion 7. Can also be given. As a result, the coiled portion 3a can be bent to allow the depth city 5 and the front feedback portion 7 to approach and separate from each other, as shown in FIG. In addition, it becomes possible to adjust the bending force by changing the winding diameter, coil pitch, etc., and the bending reaction force that acts when worn can reduce fatigue when the patient maintains an open state for treatment. Can do.
[0041]
Further, as the shape-retaining wire 3, the depth portion 5 and the front feedback portion 7 can be obtained by using a wire that is wound into a small-diameter coil over the entire length or a wire having elasticity such as a piano wire. It can be greatly bent so as to approach and separate from each other. This makes it possible to produce the same advantages as described above.
[0042]
In the suction tool 31 shown in FIG. 7, the tube 32 is cut by the locking portion 34 to expose the shape-retaining wire 33 bent into a substantially U shape and locked to any of the upper teeth. At the same time, both cut ends 32a of the tube 32 are hermetically sealed. The shape-retaining wire 33 bent into an approximately U-shape that is exposed can be easily and reliably locked to any of the upper teeth 21. Furthermore, as shown in FIG. 8, the engaging portion 34a from which the shape retaining wire 33 is exposed is covered with a soft member 35 such as rubber or synthetic resin. Can be reduced. In addition, a covered wire can also be used for the shape-retaining wire 3.
[0043]
Further, the flexibility is changed for each predetermined part of the shape-retaining wire 3, and the dentist changes the shape of the suction devices 1, 31 according to the size of the oral cavity of the patient, the tooth arrangement, etc. Can be increased. In order to make the elasticity different in structure, the predetermined part is reinforced by changing the wire diameter by drawing, etc., fitting the pipe around the outer circumference of the thin wire, caulking or screwing it in, or brazing It becomes possible to make the elasticity different by doing. Furthermore, a predetermined portion of the shape-retaining wire can be substituted with a synthetic resin wire. Also, when using a metal wire, the elasticity can be made different from that of other parts by subjecting a predetermined part to heat treatment such as energization, heating, and quenching in advance.
[0044]
By using a stainless alloy wire for the shape-retaining wire 3, the flexibility can be varied for each predetermined portion. For example, austenitic stainless steel is partly transformed into a martensitic structure and hardened by plastic working. Moreover, when the solution treatment which heats to about 1100 degreeC and cools rapidly is given, the whole will become a perfect austenite structure | tissue and will become very soft. Therefore, necessary flexibility can be imparted to a predetermined part, and the dentist can be deformed by the dentist according to the size of the oral cavity of the patient, the arrangement of teeth, etc., and excellent wearability can be realized. . And a stainless alloy wire can also be used only for the specific site | part of the wire 3 for shape retention.
[0045]
A nickel / titanium alloy wire may be used for the shape-retaining wire 3. Nickel / titanium alloys are known that exhibit superelastic characteristics, work-hardening characteristics, or shape memory characteristics. By using these characteristics alone or in combination, excellent usability and wearability can be realized. Although the nickel-titanium alloy wire depends on the composition ratio, it exhibits superelastic properties when heat treated for a long time in the vicinity of 350 ° C. to 400 ° C., but exhibits work hardening properties when heat treated for a short time. Therefore, the elasticity can be easily changed by adjusting the heat treatment conditions and the wire diameter. Therefore, the portions corresponding to the depth portion 5 and the front feedback portion 7 of the shape-retaining wire 3 are made flexible by heat treatment such as a solution treatment so as to match the height of the patient's maxillary ridge 23 or mandibular ridge 24. Since the suction tools 1 and 31 can be formed, the attachment to the oral cavity becomes more reliable, the usability is improved, and the patient's uncomfortable feeling at the time of attachment can be reduced. In addition to the nickel / titanium alloy, a copper-aluminum-nickel alloy such as a shape memory alloy, a copper-zinc-aluminum alloy, or the like can be used as the shape-retaining wire.

In addition, a pair of left and right suction tools 1, 31, 41 can be used by being attached to the left and right maxillary ridges 21 and the lower jaw ridge 24 at the same time by connecting the locking portions or connecting the suction connection portions. You can also.
[0048]
Further, the suction tool 51 shown in FIG. 10 is obtained by cutting the cheek-side front return part 57 in each suction tool at a position in the oral cavity 22 and hermetically sealing the cut end 57a. Since only one suction connection portion 58 extends outside the oral cavity 22, the patient's wearing feeling can be reduced. The front feedback portion 57 to be cut may be a tongue side one.
[0049]
In the modification of the suction tool 51 shown in FIG. 11, a substantially U-shaped bent portion 59 is formed by the shape-retaining wire 53 protruding from the sealing portion of the cut end 57 a, and the front end portion of the other front feedback portion 57 is formed. The bent portion 59 is locked to any of the lower jaw teeth. Thereby, the latching position of the suction tool 51 becomes two places by the latching | locking part 54 and the bending part 59, and the mounting | wearing in an intraoral area can be performed more reliably. Also in this case, the front feedback portion 57 to be cut may be a tongue side one. Further, the bent portion 59 may not be a wire for shape retention, but simply a wire fixed to the tip of the sealing portion.
[0050]
The suction tool 61 shown in FIG. Two rows A tube shaft member 70 is passed between the curved continuous portions 66. By inserting and fixing the handle 72 of the net 71 shown in FIG. 13 into the tube shaft member 70, the net 71 can block the throat portion. it can. Thereby, the treatment tool etc. which fell out into the oral cavity 22 accidentally during treatment are not swallowed. Instead of the net 71, a screen having air permeability may be used.
[0051]
A suction tool 81 shown in FIG. 14 has a tape-shaped isolation member 90 stretched between a depth portion 85 on the cheek side or tongue side and a front feedback portion 87. By providing the isolation member 90, it is possible to prevent the oral organs such as the tongue and the buccal mucosa from approaching the tooth portion to be treated and touching the treatment instrument or the like. Therefore, the dentist can concentrate on the treatment, and the patient is not nervous by moving the tongue to a position where it does not interfere with the treatment. Further, as shown in FIG. 15, a net-like isolation member 91 may be stretched. By using an expansion / contraction isolation member such as a tape or a net, the isolation member can be tensioned when the suction tool 81 is mounted, and the oral cavity organ of the tongue and buccal mucosa can be reliably isolated from the treatment site.
[0052]
The suction tool 101 shown in FIG. 16 cuts the buccal side front return part 97 in each of the suction tools at a position in the oral cavity 22 and forms a bent part 107a at an end thereof to straddle any of the lower jaw teeth. And is connected to the front feedback portion 107 on the lingual side so as to be suckable. Since only one suction connecting portion 108 extends outside the oral cavity 22, the patient's wearing feeling can be reduced. In addition, since the bent portion 107a is straddled over any of the lower jaw teeth, the locking position of the suction tool 101 becomes two places by the locking portion 104 and the bent portion 107a, so that the attachment to the oral cavity is more reliably performed. It can be carried out. In this case, the front feedback part 107 to be cut may be a lingual side. As shown in FIGS. 5 and 6, the locking portion 104 may have a form in which a wire for shape retention is exposed.
[0053]
FIG. 17 shows another example of mounting the suction tool 1 (41) in the oral cavity 22, and the front feedback part 7 (47) is crossed and mounted at the back of the oral cavity. Moreover, each said suction tool 51, 61, 81, and 91 can also be mounted | worn in an oral cavity in the form which reversed the top and bottom similarly to the suction tools 1, 31, and 41. FIG.
[0054]
