【０００１】
【発明の属する技術分野】
本発明は内視鏡制御ユニットの送気管路洗浄装置に係り、特に内視鏡が接続される制御ユニットに設けられた送気管路の洗浄装置に関する。
【０００２】
【従来の技術】
内視鏡が接続される制御ユニットには、光源装置等の他に送気ポンプが内蔵されている。この送気ポンプには、送気管路を介して接続部が連結され、この接続部に内視鏡が接続される。前記送気ポンプを駆動すると、送気ポンプからのエアが送気管路と接続部を介して内視鏡側に供給される。そして、内視鏡の送気バルブを開放すると、前記エアは、送気バルブから送気チャンネルを介して先端硬質部の送気孔から噴出される。
【０００３】
従来、内視鏡における送気管路については洗浄を行っているものの、制御ユニットにおいては、洗浄可能な構成になっていない。
【０００４】
【発明が解決しようとする課題】
よって、制御ユニット側の送気管路は洗浄することができないため、管路内が不衛生になる可能性があった。
本発明は、このような事情に鑑みてなされたもので、制御ユニット側の送気管路を洗浄できる内視鏡制御ユニットの送気管路洗浄装置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】
本発明は、前記目的を達成する為に、内視鏡制御ユニットにおいて、内視鏡が接続される接続部と該接続部を介して内視鏡にエア又は流体を供給する第１のポンプとを並列的に連結する２系統の送気管路と、第２のポンプを有し、前記２系統の送気管路に接続されて該２系統の送気管路を洗浄する洗浄手段と、前記２系統の送気管路に設けられると共に、該２系統の送気管路のうち一方の送気管路を前記第１のポンプと連通するように切り換えると共に、他方の送気管路を前記第２のポンプと連通するように切り換え可能なバルブと、前記第１のポンプ、前記第２のポンプ、及び前記バルブを制御して、前記２系統の送気管路のうち、一方の送気管路の使用中に、他方の送気管路を洗浄する制御手段と、を備えたことを特徴とする。
【０００６】
本発明は、送気管路を２系統に増やし、そのうちの１系統が第１のポンプに連通されて使用されている時に、別の１系統を第２のポンプに連通させて予め洗浄する。これにより、本発明は、送気管路を手間をかけずに洗浄することができる。
【０００７】
【発明の実施の形態】
以下添付図面に従って、本発明に係る内視鏡制御ユニットの送気管路洗浄装置の好ましい実施の形態について詳説する。
図１は、本発明の内視鏡制御ユニットの送気管路洗浄装置の第１の実施の形態が適用された電子内視鏡装置の全体構成図である。
【０００８】
同図に示す電子内視鏡装置１０は、電子内視鏡１２と、プロセッサ（制御ユニット）１４と、モニタＴＶ１６とを備えている。
電子内視鏡１２は、手元操作部１８を有し、この手元操作部１８には体内に挿入される挿入部２０が接続されると共に、挿入部２０の先端には湾曲部２２を介して硬質部２３が設けられている。前記湾曲部２２は、操作部１８に設けられたノブ２４を回動させることにより遠隔的に湾曲操作される。
【０００９】
前記硬質部２３には、図示しない観察窓、及び送気・送水孔等が形成されて配設され、観察窓を含む対物光学系の結像位置には固体撮像素子（ＣＣＤ）が設けられている。前記操作部１８からは、軟性ケーブル２６が延出され、この軟性ケーブル２６は、途中で２つに分岐され、一方の末端にはライトガイドコネクタ２８が設けられ、他方の末端には、電気コネクタ３０が設けられている。前記ライトガイドコネクタ２８と電気コネクタ３０とは、それぞれプロセッサ１４側のコネクタにそれぞれ接続されている。
【００１０】
前記ＣＣＤには、観察像が対物光学系を介して結像され、ここで光電変換される。光電変換された撮像信号は、ＣＣＤ出力信号としてプロセッサ１４に出力される。前記ＣＣＤ出力信号は、プロセッサ１４内で信号処理されて映像信号に生成され、この映像信号は、接続ケーブル３２を介してモニタＴＶ１６に出力される。これにより、前記モニタＴＶ１６には観察像の画像が映し出される。
【００１１】
また、前記手元操作部１８には、吸引ボタン３４と、送気・送水ボタン３６とが並設されている。前記吸引ボタン３４を押すと、前記吸引孔から液体等が吸引され、前記送気・送水ボタン３６を押すと、前記送気・送水孔から圧縮エア、若しくは洗浄液が噴射される。洗浄液は、プロセッサ１４の側面に取り付けられた送水タンク３８内に充填され、プロセッサ１４内のエアポンプによって加圧され、内視鏡内に配設された送水孔を介して送水される。
【００１２】
前記プロセッサ１４には、主電源スイッチ４２、送気スイッチ４４、オート・マニュアル選択スイッチ４５（図３参照）を介して洗浄スイッチ４６及びコネクタ挿抜検出手段４７（図３参照）が設けられる。前記オート・マニュアル選択スイッチ４５がオート位置にある時、コネクタ挿抜検出手段４７に接続され、マニュアル位置にある時、洗浄スイッチ４６に接続が切り換わるように構成されている。プロセッサ１４は、前記主電源スイッチ４２をＯＮ操作することにより起動される。また、前記送気スイッチ４４がＯＮ操作されると、図２に示す送気ポンプ（第１のポンプ）４８が駆動され、送気ポンプ４８からの圧縮エアが後述する２系統の送気管路５０、コネクタ５２、ライトガイドコネクタ２８、及び軟性ケーブル２６を介して電子内視鏡１２側に供給される。
【００１３】
図２は本発明の第１の実施の形態を示す送気管路洗浄装置の配管図である。
同図において、送気ポンプ４８には２本の分岐管路５６Ａ、５６Ｂが接続される。一方の分岐管路５６Ａには、三方弁５８の弁体Ｃ、Ｂを介して前述した送気管路５０の一方の送気管路５０Ａが接続されている。送気管路５０Ａには、三方弁６０の弁体Ａ、Ｃ、及び管路６２を介してコネクタ５２が接続されている。したがって、三方弁５８の弁体Ｃ、Ｂ及び三方弁６０の弁体Ａ、Ｃが夫々開放されると、送気ポンプ４８からの圧縮エアが分岐管路５６Ａ、送気管路５０Ａ、及び管路６２を介して電子内視鏡１２側に供給される。
【００１４】
他方の分岐管路５６Ｂには、三方弁６４の弁体Ｃ、Ｂを介して送気管路５０の他方の送気管路５０Ｂが接続されている。この送気管路５０Ｂには、三方弁６６の弁体Ａ、Ｃ、及び管路６８を介してコネクタ５２が接続されている。したがって、三方弁６４の弁体Ｃ、Ｂ及び三方弁６６の弁体Ａ、Ｃが夫々開放されている場合には、送気ポンプ４８からの圧縮エアが分岐管路５６Ｂ、送気管路５０Ｂ、及び管路６８を介して電子内視鏡１２側に供給される。
【００１５】
一方、洗浄ポンプ５４には、２本の分岐管路７０Ａ、７０Ｂが接続される。分岐管路７０Ａには、三方弁５８の弁体Ａ、Ｂを介して送気管路５０Ａが接続され、送気管路５０Ａには、三方弁６０の弁体Ａ、Ｂを介してドレン管７２Ａが接続されている。したがって、三方弁５８の弁体Ａ、Ｂ及び三方弁６０の弁体Ａ、Ｂが夫々開放されている場合には、洗浄ポンプ５４からの圧縮エアで送気管路５０Ａが洗浄され、その洗浄屑はドレン管７２Ａから外部に排出される。
【００１６】
一方、分岐管路７０Ｂには、三方弁６４の弁体Ａ、Ｂを介して送気管路５０Ｂが接続される。送気管路５０Ｂには、三方弁６０の弁体Ａ、Ｂを介してドレン管７２Ｂが接続されている。したがって、三方弁６４の弁体Ａ、Ｂ及び三方弁６６の弁体Ａ、Ｂが夫々開放されている場合には、洗浄ポンプ５４からの圧縮エアで送気管路５０Ｂが洗浄され、その洗浄屑はドレン管７２Ｂから外部に排出される。
【００１７】
図３は送気管路洗浄装置の制御系を示すブロック図である。同図に示すＣＰＵ７４は、プロセッサ１４の各装置を統括制御するもので、送気管路洗浄装置においては、送気スイッチ４４のＯＮ操作で送気ポンプ４８を駆動し、尚、送気管路５０Ａ、５０Ｂの切り換えはオート・マニュアル選択スイッチ４５がオート位置の時には、コネクタ挿抜検出手段４７により、マニュアルの位置の時には洗浄スイッチ４６のＯＮ操作で洗浄ポンプ５４を駆動し、そして三方弁５８、６０、６４、６６の開閉を制御する電磁弁駆動装置７６を制御する。洗浄スイッチ４６のＯＮ操作で洗浄ポンプ５４を駆動し、そして三方弁５８、６０、６４、６６の開閉を制御する電磁弁駆動装置７６を制御する。
【００１８】
次に、前記の如く構成された送気管路洗浄装置の作用について説明する。
この送気管路洗浄装置が新品の場合には、ＣＰＵ７４の設定で送気管路５０Ａを送気管路５０Ｂよりも先に使用するように制御する。
この場合にＣＰＵ７４は、送気スイッチ４４がＯＮされると、電磁弁駆動装置７６を制御して三方弁５８の弁体Ａを閉、弁体Ｂ、Ｃを開、そして三方弁６０の弁体Ａ、Ｃを開、弁体Ｂを閉にする。また、これと同時に、三方弁６４の弁体Ｃを閉にする。これにより、送気ポンプ４８からの圧縮エアは、送気管路５０Ａ等を介して電子内視鏡１２側に供給される。この時、送気管路５０Ｂは、三方弁６４の弁体Ｃが閉じているので送気使用されない。
【００１９】
次に、送気管路５０Ａを洗浄、送気管路５０Ｂを送気使用する際の、ＣＰＵ７４による三方弁の制御について図４を参照しながら説明する。
送気スイッチ４４がＯＮ操作され、これと同時に洗浄スイッチ４６がＯＮ操作されると、図４に示すように、三方弁５８の弁体Ａ、Ｂを開、弁体Ｃを閉、三方弁６０の弁体Ａ、Ｂを開、弁体Ｃを閉、三方弁６４の弁体Ａを閉、弁体Ｂ、Ｃを開、三方弁６８の弁体Ａ、Ｃを開、弁体Ｂを閉じる。
【００２０】
これにより、送気ポンプ４８からの圧縮エアは、送気管路５０Ｂ等を介して電子内視鏡１２側に供給され、これと同時に送気管路５０Ａが、洗浄ポンプ５４からの圧縮エアでエアブローされて洗浄される。洗浄屑は、ドレン管７２Ａから外部に排出される。したがって、本実施の形態では、送気管路５０Ｂを送気使用する時に、送気管路５０Ａを洗浄することができる。なお、洗浄ポンプ５４は、所定時間（洗浄が確実に行われる時間）経過した時に停止するようにＣＰＵ７４で制御されている。
【００２１】
次に、送気管路５０Ｂを洗浄、送気管路５０Ａを送気使用する際の、ＣＰＵ７４による三方弁の制御について図５を参照しながら説明する。
送気スイッチ４４がＯＮ操作されて洗浄スイッチ４６がＯＮ操作されると、図５に示すように、三方弁５８の弁体Ａを閉、弁体Ｂ、Ｃを開、三方弁６０の弁体Ａ、Ｃを開、弁体Ｂを閉、三方弁６４の弁体Ａ、Ｂを開、弁体Ｃを閉、三方弁６８の弁体Ａ、Ｂを開、弁体Ｃを閉じる。
【００２２】
これにより、送気ポンプ４８からの圧縮エアは、送気管路５０Ａ等を介して電子内視鏡１２側に供給され、これと同時に送気管路５０Ｂが、洗浄ポンプ５４からの圧縮エアで洗浄される。洗浄屑は、ドレン管７２Ｂから外部に排出される。また、ＣＰＵ７４により送気管路５０Ａ、５０Ｂのうち使用されている管路を判断し、次に洗浄する管路を決定する。
【００２３】
したがって、本実施の形態では、送気管路５０を２系統５０Ａ、５０Ｂに増やし、そのうちの１系統が使用されている時に、別の１系統を洗浄することが可能である。
図６は、本発明の送気管路洗浄装置の第２の実施の形態を示す配管図であり、第１の実施の形態と同一若しくは類似の部材については同一の符号を付してその説明は省略する。
【００２４】
同図に示す送気管路洗浄装置は、三方弁に変えてバルブ７８〜９２を使用した装置である。即ち、送水ポンプ４８からの分岐管路５６Ａにバルブ７８を取り付け、分岐管路５６Ｂにバルブ８０を取り付けている。また、コネクタ５２に連通される管路６２にバルブ８２が、管路６８にバルブ８４がそれぞれ取り付けられている。更に、洗浄ポンプ５４からの分岐管路７０Ａにバルブ８６が、分岐管路７０Ｂにバルブ７０Ｂが取り付けられ、そして、ドレン管７２Ａにバルブ９０が、ドレン管７２Ｂにバルブ９２が取り付けられている。これらのバルブ７８〜９２は、バルブ駆動装置によって開閉制御され、このバルブ駆動装置はＣＰＵによって制御されている。
【００２５】
この送気管路洗浄装置で送気管路５０Ａを洗浄し、送気管路５０Ｂを使用する場合には、バルブ７８、８２、８８、９２を閉、バルブ８０、８４、８６、９０を開く。これにより、送気管路５０Ａが洗浄され、送気管路５０Ｂが送気用に使用される。これとは反対に、送気管路５０Ａを使用し、送気管路５０Ｂを洗浄する場合には、バルブ７８、８２、８８、９２を開、バルブ８０、８４、８６、９０を閉じるこれにより、送気管路５０Ａが使用され、送気管路５０Ｂが洗浄される。
【００２６】
図７は、本発明の送気管路洗浄装置の第３の実施の形態を示す配管図であり、第１の実施の形態と同一若しくは類似の部材については同一の符号を付してその説明は省略する。
同図に示す送気管路洗浄装置は、一対の送気ポンブ４８Ａ、４８Ｂを備え、送気ポンプ４８Ａを送気管路５０Ａ、三方弁９４、管路６２を介してコネクタ５２に連通し、送気ポンプ４８Ｂを送気管路５０Ｂ、三方弁９６、管路６８を介してコネクタ５２に夫々連通させたものである。
【００２７】
したがって、送気管路５０Ａを送気使用し、送気管路５０Ｂを洗浄する場合には、各々の送気ポンプ４８Ａ、４８Ｂを駆動すると共に、三方弁９４の弁体Ａ、Ｃを開、弁体Ｂを閉、三方弁９６の弁体Ａ、Ｂを開、弁体Ｃを閉じる。これにより、送気管路５０Ａが送気使用され、送気管路５０Ｂが送気ポンプ４８Ｂからの圧縮エアで洗浄される。
【００２８】
また、送気管路５０Ｂを送気使用し、送気管路５０Ａを洗浄する場合には、各々の送気ポンプ４８Ａ、４８Ｂを駆動すると共に、三方弁９４の弁体Ａ、Ｂを開、弁体Ｃを閉、三方弁９６の弁体Ａ、Ｃを開、弁体Ｂを閉じる。これにより、送気管路５０Ｂが送気使用され、送気管路５０Ａが送気ポンプ４８Ａからの圧縮エアで洗浄される。
【００２９】
本実施の形態では、圧縮エアで送気管路５０Ａ、５０Ｂを洗浄するようにしたが、これに限られるものではなく、溶剤や洗浄液等の液体で洗浄するようにしても良い。
また、本実施の形態では、送気管路について説明したが、送水管路についても適用することができる。
【００３０】
本実施の形態では、オート・マニュアル選択スイッチ４５を切り換えるものとして説明したが、オート、マニュアルの一方のみ設けるようにしても良いことは言うまでもない。
更に、本実施の形態では、内視鏡として電子内視鏡を例に上げて説明したが、これに限られるものではなく、他の種類の内視鏡にも適用することができる。
【００３１】
【発明の効果】
以上説明したように、本発明に係る内視鏡制御ユニットの送気管路洗浄装置によれば、制御ユニット側の送気管路を洗浄することが可能となり、管路内を清浄に保つことができる。さらに、送気管路を２系統に増やし、そのうちの１系統を使用している時に、他の１系統を洗浄手段によって洗浄するようにしたので、一方の系統の送気管路と組合せ使用した内視鏡を取り外し続けて他の内視鏡を使用する際には、他方の系統の送気管路を使用し、その使用中に上記一方の系統の送気管路の洗浄ができるように、一つの制御ユニットで内視鏡の交換使用を衛生的に続いて行うことができる。
