Description

【０００１】
【発明の属する技術分野】
この発明は、内視鏡を使用した後で内視鏡の管路内をブラッシングして掃除するための内視鏡の管路内掃除具に関する。
【０００２】
【従来の技術】
内視鏡の管路内掃除用ブラシは一般に、可撓性を有する細長いシャフトの先端部分にブラシ毛が放射状に植設され、手元側端部には取っ手が設けられて形成されており、シャフトを指先で持って、内視鏡の管路内に挿脱されるようになっている。
【０００３】
【発明が解決しようとする課題】
しかし、シャフトは内視鏡の管路の長さより長く形成されるので非常に長尺である。そのため、内視鏡の管路に挿入する際に、先端を管路の軸線に合わせて真っ直ぐに対向させるのが容易でなく、挿入操作がやり難かった。また、内視鏡の管路に挿脱を行う際に、手元側の取っ手が振り回されて周囲にぶつかり、煩わしかった。
【０００４】
そこで本発明は、内視鏡の管路への挿脱操作が容易な内視鏡の管路内掃除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】
上記の目的を達成するため、本発明の内視鏡の管路内掃除具は、可撓性を有する細長いシャフトにブラシ毛が放射状に植設されて形成されたブラシ本体を回転自在なドラムに巻き付け、上記ドラムから内視鏡の管路入口に向けて上記ブラシ本体を繰り出し或いは上記ドラムに巻き取るように上記ドラムを手動で回転させるための操作ハンドルを設けたことを特徴とする。
【０００６】
なお、上記ブラシ毛が上記シャフトの先端部分付近だけに植設されていてもよい。また、上記ブラシ毛が上記シャフトの複数カ所に断続的に植設されていてもよく、上記ブラシ毛が上記シャフトに先側から連続的に広範囲に植設されていてもよい。
また、上記ブラシ本体に対して上記ドラムから繰り出された位置において洗浄液をかけるためのブラシ洗浄手段が設けられていてもよい。
【０００７】
【発明の実施の形態】
図面を参照して本発明の実施の形態を説明する。
図１は本発明の第１の実施の形態を示しており、内視鏡を使用した後で内視鏡の管路内（送気送水管路や吸引管路等）をブラッシング掃除する際の状態を示している。
【０００８】
内視鏡１０は、挿入部１２の基端に連結された操作部１１が載置台１上に載せられており、送気送水操作弁と吸引操作弁を取り外した後の、送気送水管路への入口開口１３と吸引管路への入口開口１４とが、並んで上方に向いて開口した状態になっている。
【０００９】
管路内掃除具２０はハウジング２１で囲まれて構成されており、回転自在な二つのドラム２２がハウジング２１内に収容されている。各ドラム２２には、可撓性を有する細長いシャフト２３１にブラシ毛２３２が放射状に植設されて形成されたブラシ本体２３が巻き付けられている。この実施の形態では、ブラシ毛２３２はシャフト２３１の先端部分にのみ植設されている。
【００１０】
ブラシ本体２３のドラム２２から繰り出された部分は、ハウジング２１に形成されたスリット２４から外部に引き出されていて、内視鏡１０の送気送水管路入口開口１３又は吸引管路入口開口１４にほぼ真っ直ぐに挿入することができる（そのような位置に管路内掃除具２０が配置されている）。
【００１１】
二つのドラム２２は互いに独立して回転自在であり、各々を手動操作で外部から回転させるための操作ハンドル２５が各ドラム２２に突設されている。したがって、操作ハンドル２５を指先で摘んでドラム２２を回転させることにより、ドラム２２からブラシ本体２３を繰り出し、或いはドラム２２にブラシ本体２３を巻き取ることができる。
【００１２】
管路内掃除具２０の側面断面図である図２に明瞭に示されるように、隔壁２６によってドラム２２と仕切られた洗浄室２７には、そこを通過するブラシ本体２３に洗浄液を吹き付けるための洗浄液吐出管２８と、洗浄室２７内に噴射された洗浄液を排出するための洗浄液排出管２９とが接続されている。
【００１３】
このように構成された実施の形態の内視鏡の管路内掃除具２０によれば、内視鏡１０を使用した後で内視鏡１０の管路内にブラシ本体２３を挿入する際には、操作ハンドル２５を指先で握ってドラム２２を回転させ、ドラム２２からブラシ本体２３を下方に繰り出すことによって、ブラシ本体２３を真っ直ぐに管路開口１３，１４に挿入することができる。
【００１４】
また、ドラム２２を逆方向に回転させれば、繰り出されたブラシ本体２３をドラム２２に巻き取ることができる。なお、巻き取り用の動力を与えるための付勢手段を設けてもよい。
【００１５】
そのような操作の最中、シャフト２３１の余分な部分はドラム２２に巻き付けられているので操作の邪魔にならず、ブラシ本体２３を管路開口１３，１４に容易に挿脱することができる。
【００１６】
図３及び図４は本発明の第２の実施の形態を示しており、ブラシ本体２３のシャフト２３１を内視鏡１０の管路長の数倍（例えば３ないし１０倍）の長さに設定すると共に、ブラシ毛２３２をシャフト２３１の複数カ所（例えば数十箇所ないし百数十箇所）に断続的に植設したものである。なお、ハウジング２１や操作ハンドル２５等は図示が省略されている。
【００１７】
このようにすると、図３に示されるように、ブラシ本体２３を内視鏡の管路に挿入後、鋏１００等でシャフト２３１を適当な長さに切断して、洗浄に使用後のブラシ本体２３は廃棄し、順次新しいブラシ本体２３を使用することができる。
【００１８】
図５は本発明の第３の実施の形態を示しており、ブラシ毛２３２を、シャフト２３１に対して先端側からほぼ全長にわたって連続的に植設した点だけが上述の第２の実施の形態と相違する。
【００１９】
このようにすると、ブラッシングの際の洗浄性が向上するだけでなく、シャフト２３１を切断する箇所を選択する必要がなくて便利である。
【００２０】
【発明の効果】
本発明によれば、ブラシ本体のシャフトの余分な部分は内視鏡の管路への挿脱時にドラムに巻き付けられているので、挿脱操作の邪魔にならず、ドラムを回転させることにより、ブラシ本体を内視鏡の管路開口に真っ直ぐに対向させて容易に挿脱することができる。
