Description

【0001】
【産業上の利用分野】
本発明はハンドピースに取着される歯科研削バー、ファイル、スケーラ等の歯科治療用インストルメントを随時、簡易かつ確実に洗浄できる超音波洗浄器を備えた歯科治療装置に関する。
【0002】
【従来の技術及び発明が解決しようとする課題】
従来、歯科治療においてハンドピース先端に取着して使用された使用済みの研削バー、リーマあるいはスケーラ等は、例えば1日分をまとめて加熱殺菌器に入れるなどして殺菌処理されていた。
しかし一般にはバー、ファイル、リーマ、スケーラ等は使用後に取り替えることもなく、そのまま次の患者の歯科治療に使用されており、患者間における病気の伝染を防止できない実態にある。
【0003】
【課題を解決するための手段及び作用】
本発明は上記課題を解決するものであり、すなわち患者着座用椅子、照明灯、歯科用治療器具載置用ブラケットテーブル等からなる歯科用治療装置において、前記歯科用治療器具載置用ブラケットテーブル上方でハンドピース先端から取外される研削バー、リーマ、スケーラ等の歯科用インスツルメントが投入される洗浄槽を備えた超音波洗浄器を、前記取外操作部の直近位置である前記ブラケットテーブルに凹設してなることを特徴とする超音波洗浄器を備えた歯科用治療装置である。超音波洗浄器をブラケットテーブルに凹設したことにより、通常そのテーブル上方でハンドピース等から取り外し操作が行われる研削バー、リーマ等を、その操作箇所直近位置の凹部超音波洗浄器の洗浄槽へ単に投げ入れ、同洗浄器の操作スイッチを押すだけで、超音波洗浄作業が実行可能となる。本発明に係る超音波洗浄槽によれば付与される超音波洗振動により、研削バー30表面に付着した汚れは、振動による乳化、撹拌、分散作用等により除去されて洗浄され、また、この超音波振動により、ブドウ球菌、レンサ菌、スペロヘータ、大腸菌、サルモネラ菌等の大多数のばい菌類が破壊・殺菌される。
【0004】
【実施例】
本発明の歯科用治療装置の一実施例について以下図面に基づき具体的に説明する。
図1は本発明実施例の超音波洗浄器を備えた歯科用治療装置の斜視図を表わし、図2は要部拡大断面図、図3は要部分解図を示す。
図1において、1は患者2を着座させる歯科用治療椅子であり、該歯科用治療椅子1は治療台シート3とこれに傾動自在に取着されたバックレスト4と該バックレスト4の先端部に配設されたヘッドレスト5とから構成されている。
前記治療台シート3の下方に取り付けられている昇降装置6は、患者が治療台シート3上に乗り降りし易く、また、術者の治療時の姿勢に無理がないように治療台シート3が上下適当位置に昇降させるものである。
また、該歯科用治療椅子1の周辺部には、歯科治療の開始時及び終了時に患者が口内を濯げるように給排水設備としてスピットンユニット7が設けられ、さらに該スピットンユニット7と一体に形成された照明灯用ポール8及びアーム9により支持され、上方より患部口腔部を照らすための照明灯10が配設されている。
そして、該スピットンユニット7と連なって形成されたアーム11によって支持されるブラケットテーブル15が設けられ、該ブラケットテーブル15上には作業用トレイ12、バーナー13、ハンドピース14等の歯科治療器具が載置されている。なお、ハンドピース14の先端には研削バー30が取着されている。さらに、該ブラケットテーブル15にはその後端部にX線フイルムビュアー16が立設されている。
そしてまた、これら歯科用治療椅子1、スピットンユニット7、照明灯10及びテーブル台15等を駆動制御させる駆動制御ボックス17・・等が配設されている。
【0005】
本発明においては前記ブラケットテーブル15上に、超音波洗浄器20を凹設してあり、術者がハンドピース14先端に取着して使用した研削バー30を、取り外して、直近位置の超音波洗浄器20の洗浄槽中へ即座に投入することができるものである。
超音波洗浄器20の詳細構造は、図2にその取り付け状態の断面図を、図3にその組み立て図を示すごときものである。
すなわち、図中20は超音波洗浄器、200は超音波振動子、200aはリード線、201は超音波洗浄槽、202は洗浄槽カバー、203はシリコン樹脂リング、204は洗浄槽受、205はキャップ、206は接点、207は網籠、そして207aは網籠取手である。
21は洗浄槽保護筒体、22はスイッチボタン、23はLED、24は交流電源、25は制御器、26はバネ電極、26aはリード線、そして27は支持板である。
超音波洗浄槽201の網籠207中に投入された研削バー30に対して、洗浄液208を介して超音波振動が伝達され、その洗浄が行われるものである。
本例では、周波数80〜120kHzの超音波振動が超音波振動子(PZTセラミック振動子)200により付与される。
【0006】
本超音波洗振動によれば、研削バー30表面に付着した汚れは、振動による乳化、撹拌、分散作用等により除去されて洗浄される。
また、この種超音波振動の付与により、各種病原菌、例えばブドウ球菌、レンサ菌、スペロヘータ、大腸菌、サルモネラ菌等の大多数のばい菌類が破壊・殺菌される利点もある。
【0007】
【発明の効果】
以上実施例等で詳述したごとく、本発明装置によれば、ブラケットテーブル上方でハンドピース等から取り外し操作が行われる研削バー、リーマ、スケーラ等を、その操作箇所直近位置の凹部超音波洗浄器の洗浄槽へ単に投げ入れ、同洗浄器の操作スイッチを押すだけで、研削バー等の超音波洗浄作業が実施され、衛生管理が容易に実行できることとなる。
また、超音波洗浄によりブドウ球菌、レンサ菌、スペロヘータ、サルモネラ菌等の病原菌が殺菌されるたため、患者間、患者医師、ナース間の病気伝染を阻止できる
