【００６５】
この電解水２６は、前記ポンプ６の作動により、ノズル５から脈動的に（脈動流として）噴射される。
【００６６】
すなわち、ピストン６２が図５中下側から上側に移動すると、シリンダ６１内が減圧され、これにより、電解部４で生成された電解水２６が流入口６１１から一方向弁６３１を通過して中空部６１３へ吸入される。
【００６７】
次いで、ピストン６２が図５中上側から下側に移動すると、シリンダ６１内が加圧され、これにより、中空部６１３内の電解水２６が一方向弁６３２を通過して流出口６１２から突出（排出）され、ノズル５から噴射される。
前記の動作が繰り返され、電解水２６がノズル５から脈動的に噴射する。
【００６８】
図８は、ノズル５から噴射される電解水２６の打力の経時変化を示すグラフである。条件は、ノズル５の先端のオリフィス径（電解水噴出口の直径）ｒ＝０．０６ｃｍ、電解水２６の流量の平均値Ｌ＝２．８ｍｌ／秒である。なお、打力の測定方法については、後に詳述する。
【００６９】
同図に示すように、電解水２６がノズル５から脈動的に噴射することにより、ノズル５から噴射される電解水２６の流量が変化し、これにより、前記電解水２６の打力が変化する（略波形状になる）。
【００７０】
前記噴射された電解水２６の噴流（脈動流）は、消毒・除菌の対象物（例えば生体の表面）に衝突し、消毒・除菌を行う。
【００７１】
レバー３３の握りを解除すると、電極対への通電およびモータ６６への通電が停止し、電解水２６の生成および噴射が停止する。
【００７２】
容器２１内の被電解水２５が空になったら、容器２１内に被電解水２５を補充し、使用を継続することができる。
【００７３】
なお、脈動流には、図９に示すように、電解水２６を連続的に噴射した場合の連続流と、図１０に示すように、電解水２６を間欠的に噴射した場合の間欠流とが含まれる。
【００７４】
ノズル５から噴射される電解水２６は、そのｐＨが３〜７程度であるのが好ましく、４〜６．５程度であるのがより好ましく、４．５〜５．５程度であるのがさらに好ましい。図６は、電解水２６中に含まれる有効塩素、すなわち次亜塩素酸（ＨＯＣｌ）、次亜塩素酸イオン（ＯＣｌ^-）、塩素分子（Ｃｌ₂）の存在比率のｐＨに対する変化を示している。図６に示すように、ｐＨが小さ過ぎると、電解水中の塩素分子の存在比率が高くなる傾向を示し、有効塩素量が不安定になり、逆に、ｐＨが大き過ぎると、電解水中の次亜塩素酸イオンの存在比率が高くなる傾向を示し、いずれの場合にも、消毒・除菌効果（特に蛋白存在下での殺菌効果）が低下する。従って、電解水のｐＨは、上記範囲が好ましい。
【００７５】
また、ノズル５から噴射される電解水２６は、その有効塩素濃度が１〜２００ｐｐｍ程度であるのが好ましく、３０〜１００ｐｐｍ程度であるのがより好ましく、５０〜８０ｐｐｍ程度であるのが特に好ましい。有効塩素濃度が低過ぎると、後述する打力が比較的低い場合に消毒・除菌効果（特に蛋白存在下での殺菌効果）が十分に発揮されず、また、有効塩素濃度が高過ぎると、人体に対し使用する場合に、安全性が低下する。従って、用途が人体に対するものでない場合には、有効塩素濃度は２００ｐｐｍを超えるものであってもよい。
【００７６】
また、ノズル５から噴射される電解水２６は、その脈動数が６０〜３０００回／分程度であるのが好ましく、１００〜２５００回／分程度であるのがより好ましい。
【００７７】
この脈動数が６０回／分未満であると、後述する打力が比較的弱い場合や流量が比較的少ない場合等においては、消毒・除菌効果の向上が十分ではなく、また、３０００回／分を超えても、それ以上の消毒・除菌効果の向上は見られない。
【００７８】
また、ノズル５から噴射される電解水２６は、その打力の平均値、すなわちノズル５の先端から３ｃｍ離れた位置における打力の平均値が０．５〜１１ｇｆ程度であるのが好ましい。
【００７９】
この打力の平均値が０．５ｇｆ未満であると、後述する流量が比較的少ない場合等においては、消毒・除菌効果の向上が十分ではなく、また、打力の平均値が１１ｇｆを超えても、それ以上の消毒・除菌効果の向上は見られない。
【００８０】
なお、本発明の電解水供給装置１を人体（生体）の消毒・除菌に用いる場合、前記打力の平均値は、０．５〜９ｇｆ程度が好ましく、０．５〜７ｇｆ程度がさらに好ましく、０．７〜４ｇｆ程度が特に好ましい。打力の平均値が高すぎると、人体の箇所によっては、大きな痛みを与えるおそれがある。
【００８１】
また、ノズル５から噴射される電解水２６は、その流量（噴出口１個当たりの流量）の平均値が０．３〜７ｍｌ／秒程度であるのが好ましく、１〜５ｍｌ／秒程度であるのがより好ましい。
【００８２】
この流量の平均値が０．３ｍｌ／秒未満であると、前記打力が比較的弱い場合等においては、消毒・除菌効果の向上が十分ではない場合があり、また、流量の平均値が７ｍｌ／秒を超えても、それ以上の消毒・除菌効果の向上は見られず、電解水の無駄が多くなる。
【００８３】
本発明では、電解水を脈動的に噴射させ、特に、前述した条件で消毒・除菌、（特に人体の創傷部の消毒・除菌）を行うことにより、少量の電解水（洗浄液）で効果的な消毒・除菌を行うことができる。
【００８４】
この場合、電解水には生きている細菌が存在しないか、またはその菌数が少なく、また、創傷部の電解水の当たった部分は、その電解水により消毒・除菌されるので、許容される痛さの範囲で前記打力を大きくしても、電解水によって生きている細菌を創傷部の内部の組織に侵入させてしまうことがほどんどなく、創傷部の内部の組織まで十分に消毒・除菌することができる。
【００８５】
また、消毒・除菌に用いられた電解水および消毒・除菌の際に創傷部（皮膚創傷部）から跳ね返った電解水の飛沫（飛沫液）は、自己の殺菌力により殺菌されているので、これらによる２次感染を防止することができ、安全性が高い。
【００８６】
また、人体の創傷部（皮膚創傷部）から跳ね返った電解水の飛沫（飛沫液）が周囲に飛び散った場合でも、前記飛沫は、電解水の殺菌力により殺菌されているので、飛沫による２次感染を防止することができる。
【００８７】
ここで、ノズル５から噴射される電解水２６の打力（平均値）および脈動数の測定方法について説明する。
【００８８】
図７は、打力および脈動数の測定方法を示す図である。ロードセル１０は、受け板（プラスチック製）１１を有している。ロードセル１０は、コンピュータ１２に接続されており、そのコンピュータ１２にはモニタ１３が接続されている。
受け板２に付与された応力は、ロードセル１０で測定され、そのデータは、コンピュータ１２に入力され、時間と対応し得るように記憶される。この応力の測定は、ほぼ連続的または非常に短い時間間隔で繰り返し行われ、コンピュータ１２では、所定の演算処理（応力の平均値の算出、単位時間当りの脈動数の算出等）がなされる。
【００８９】
なお、縦軸を打力（応力）、横軸を時間としたグラフ（打力の経時変化を示すグラフ）を作成すると、電解水の噴流８が脈動流の場合には、そのグラフは、略波形状（図８参照）になり、電解水の噴流８が定常流の場合には、そのグラフは、略直線状になる。
【００９０】
測定の際は、ノズル５の先端が受け板１２から３ｃｍの距離離れた位置となるようにノズル５を固定し、ノズル５の先端開口から水平に噴射される電解水の噴流（ジェット）８を受け板１２に垂直に衝突させる。これにより受け板１１に噴流８による打力（応力）が付与され、そのデータがコンピュータ１２に入力され、コンピュータ１２において所定の演算処理がなされ、求まった値、すなわち打力の平均値および１分間当りの脈動数がそれぞれモニタ１３に表示される。
【００９１】
ノズル５からの電解水の噴射を開始してから５秒経過後の安定状態となった時点からのデータより求めた値をそれぞれ本発明における打力の平均値および脈動数とする。この場合、前記打力の経時変化を示すグラフの極大点から、その極大値に対して１０％以上低下した極小点（極小値）を経て、次の極大点に至るまでの時間を１回の脈動流の時間とする。
【００９２】
本発明の電解水供給装置１は、例えば皮膚や皮膚欠損部のような表面に小さな凹凸を有する部位や、細い隙間を有する部位の消毒・除菌に用いるのに適している。
【００９３】
すなわち、電解水を脈動的に噴射させることにより、その電解水が失活することなく前記小さな凹凸の凹部の奥（底）や細い隙間まで到達し、消毒・除菌を行うことができる。
【００９４】
また、電解水を脈動的に噴射させ、かつ、脈動数、打力の平均値、流量の平均値等を前述した好適範囲に設定した場合には、消毒・除菌効果がさらに向上する。
【００９５】
電解水供給装置１において、ノズル５から噴射される電解水２６の脈動流は、被電解水２５の供給口からノズル５に至るまでの管路（流路）等により緩衝されることもあり得るので、その管路の形状、寸法（内径）や、ノズル５の噴出口の形態、形状、寸法（開口面積）、さらには電解水２６の流量等の条件を適宜設定することにより、前述した範囲の脈動流を得る。また、これらの条件を適宜設定することにより、前述した範囲の打力を得る。
【００９６】
ノズル５の形態（噴射形態）等は特に限定されず、脈動流が得られるものであれば、いかなるものでもよいが、電解水２６を１本または複数本の線状に（ジェットとして）噴出し得るものが好ましく、電解水２６を１本の線状に噴出し得るもの（直噴）がより好ましい。
【００９７】
また、ノズル５は、例えば、電解水２６をシャワー状に噴出する形態、電解水２６を霧状に噴霧する形態等、噴流が揺動または回転するように噴出する形態等、他の１または２以上の噴射形態に切り替え可能なものでもよく、あるいは、これら複数の噴射形態を併用し得るものでもよい。
【００９８】
また、図示の構成では、ノズル５は、操作部本体３０に対し一体形成または固着されているが、操作部本体３０に対し、着脱可能とすることもできる。また、異なる種類、形状の複数のノズル５を交換可能に装着するような構成としてもよい。
【００９９】
以上のような電解水供給装置１では、操作部３におけるレバー３３の操作により、電解部４の作動による電解水２６の生成と、送液によるノズル５からの電解水２６の噴出とが、同期的に行われる。これにより、必要時に必要量の電解水２６を生成し、使用することができるとともに、常に活性に富んだ電解水２６を供給することができ、優れた消毒・除菌効果が安定して得られる。
【０１００】
また、電解水供給装置１では、レバー３３を握っている間、電解水２６が噴出するので、レバー３３を握っている時間により、電解水２６の積算噴出量を調節することができる。
【０１０１】
また、操作部３は、小型、軽量であるとともに、貯留部２から離間し、可撓性を有するチューブ７０で接続されてその姿勢や位置を自由に設定できるので、電解水２６の噴出（目的部位への供給）の操作を極めて容易に行うことができる。
【０１０２】
また、電解水供給装置１全体も、小型、軽量である。従って、携帯に適する。
例えば、患者が電解水供給装置１を携帯し、患者自身の患部や留置カテーテルの経皮開口部等を定期的に消毒・除菌するのに適している。
【０１０３】
なお、本発明において、脈動手段、送液手段は、前述したポンプ６に限定されるものではなく、また、脈動手段、送液手段の位置も図示の位置に限定されない。
【０１０４】
例えば、脈動手段、送液手段は、電動のものに限らず、手動により作動するものであってもよい。
【０１０５】
また、脈動手段、送液手段をポンプで構成する場合、そのポンプの種類、機能、構造等は、特に限定されない。
【０１０６】
また、ポンプ６は、例えば、操作部３であって、電解部４より上流側（基端側）に設けられていてもよい。
【０１０７】
また、本発明では、脈動手段と送液手段とを別々に設けてもよい。
この場合、送液手段が、例えば、操作部３であって、電解部４より上流側（基端側）に設けられていてもよく、また、貯留部２に設けられていてもよい。また、脈動手段が、例えば、操作部３であって、電解部４より上流側（基端側）に設けられていてもよい。
【０１０８】
また、脈動手段、送液手段は、ポンプによるものに限らず、簡易な構成のものとして、例えば、貯留部２を高所へ置き、一方向弁の開閉等を行ないつつ、落差により送液するような構成のものでもよい。
【０１０９】
また、本発明の電解水供給装置は、貯留部と操作部（電解部）とが一体的に形成されたものでもよい。貯留部と操作部が一体であることにより、より一層携帯に適する。
【０１１０】
次に、本発明の電解水供給装置の他の実施例（第２実施例）について説明する。なお、前述した実施例との共通点については、説明を省略し、主な相違点を説明する。
【０１１１】
図１１は、本発明の電解水供給装置の他の実施例を示す断面側面図、図１２および図１３は、それぞれ、図１１に示す電解水供給装置のダイヤフラムポンプの構造を模式的に示す断面側面図である。なお、説明の都合上、図１１〜図１３中の右側を「基端」、左側を「先端」、上側を「上端」、下側を「下端」と言う。
【０１１２】
図１１に示すように、本発明の電解水供給装置（電解水噴射装置）１は、被電解水を貯留する貯留部２と、電解水を噴出させるための操作を行う操作部３と、被電解水を電解（電気分解）して電解水とする電解部４と、電解部４で生成された電解水を噴出するノズル５と、貯留部２とノズル５とを接続する送液路７と、ポンプ６０１とを有し、これらが集合して一体的に構成されている。ポンプ６０１は、被電解水２５を送液路７に沿って送液する送液手段と、ノズル５から電解水を脈動的に噴射させる脈動手段とを兼ねる。以下、これらについて説明する。
【０１１３】
操作部３は、内部流路３１を有する操作部本体３０と、操作部本体３０に対し図１１中横方向に移動可能（押し引き可能）に設置されたボタン３４とを有している。
【０１１４】
ボタン３４は、操作部本体３０の基端部に設置され、図示しないトーションバネ等の付勢手段により、基端方向へ、すなわち、操作部本体３０と離間する方向に付勢されている。
【０１１５】
このボタン３４の下側、すなわち、操作部本体３０の基端側の下部には、手で把持するためのグリップ部３２が形成されている。
【０１１６】
また、操作部本体３０の中央部の下部には、Ｌ字状の基台（スタンド部）３５が形成されている。
【０１１７】
また、操作部本体３０の中央部の下部には、後述する容器２４が着脱自在に取り付けられる取付部３６が形成されている。そして、この取付部３６の上側には、上端が操作部本体３０の内部に開放し、下端が取付部３６に開放する孔３７が形成されている。
【０１１８】
また、操作部本体３０には、電解部４と、送液手段と脈動手段とを兼ねるポンプ６０１と、チューブ７３と、チューブ７４とが、それぞれ内蔵されている。
【０１１９】
チューブ７３の下端部は、操作部本体３０の孔３７に挿入され、上端部は、図１２に示すように、ポンプ６０１の流入口６１１側に接続されている。
【０１２０】
一方、チューブ７４の先端部は、その内腔が内部流路３１と連通するように操作部本体３０に接続され、下端部は、図１２に示すように、ポンプ６０１の流出口６１２側に接続されている。
【０１２１】
これらチューブ７３および７４は、それぞれ、例えば、可撓性を有するポリ塩化ビニル、ポリエチレン、ポリプロピレン、エチレン−酢酸ビニル共重合体（ＥＶＡ）等のポリオレフィン、ポリアミド、ポリエステル、シリコーンゴム、ポリウレタン等の高分子材料で構成されていてもよいが、チタン、ステンレス鋼等の金属で構成されていてもよい。
【０１２２】
また、操作部本体３０の先端部には、内部流路３１と連通するノズル５が形成（または接続）されている。
【０１２３】
貯留部２は、容器２４で構成され、この容器２４の内部には、所定量の被電解水２５が貯留されている。容器２４は、本実施例の場合、軟質なものであり、その構成材料としては、例えば、塩化ビニル、ポリエチレン、ポリプロピレン、ポリエステル等が挙げられる。
【０１２４】
容器２４は、その接続部２２により、操作部本体３０の取付部３６に接続され、ポンプ６０１による被電解水２５の吸上げにより、変形する。
【０１２５】
容器２４の接続部２２には、側孔付チューブ２３の上端部が挿入される孔（貫通孔）２２１が形成されている。
【０１２６】
側孔付チューブ２３は、容器２４内の被電解水２５中に浸漬され、その上端部は、接続部２２の孔２２１に挿入されている（固定されている）。
【０１２７】
容器２４が操作部本体３０の取付部３６に接続されると、側孔付チューブ２３の上端面とチューブ７３の下端面とが液密に当接し、側孔付チューブ２３の内腔とチューブ７３の内腔とが連通する。
【０１２８】
なお、側孔付チューブ２３を用いることにより、容器２４内の被電解水２５を無駄なく吸上げることができる。
【０１２９】
前記側孔付チューブ２３の内腔、チューブ７３の内腔、チューブ７４の内腔ならびに内部流路３１により、送液路７が形成される。
【０１３０】
ポンプ６０１は、貯留部２と電解部４との間に配置されている。前記チューブ７４を硬質材料で構成することにより、このポンプ６０１で電解水を精度良く脈動（脈動的に噴射）させることができる。なお、本発明では、ポンプ６０１が前記以外の位置に配置されていてもよいことは、言うまでもない。
【０１３１】
本実施例におけるポンプ６０１は、図１２および図１３に示すように、ダイヤフラムポンプであり、送液路７の途中に設置され、この送液路７と連通する一対のポンプ室７６、７６と、ポンプ室７６、７６に接続された一対のシリンダ６１、６１と、シリンダ６１、６１内を往復動する一対のピストン６２、６２と、ポンプ室７６、７６の内壁面とピストン６２、６２の外壁面とを接続する一対のダイヤフラム７５、７５と、モータ６６と、一対のロッド６４、６４、ギヤ６５および６７で構成された動力伝達手段とで構成されている。
【０１３２】
前記一対のポンプ室７６、７６、一対のシリンダ６１、６１、一対のピストン６２、６２、一対のダイヤフラム７５、７５、一対のロッド６４、６４等は、それぞれ同様の構造であるので、以下、代表的に、これらのうちの一方を説明する。
【０１３３】
シリンダ６１の一端側（先端側）にはポンプ室７６が接続され、他端側（基端側）には開口が形成されている。
【０１３４】
チューブ７３の内腔に連通しているポンプ６０１の内部流路７７は、位置ａで、２つに分岐し、そのうちの一方の内部流路７７は、一方のポンプ室７６に連通し、他方の内部流路７７は、他方のポンプ室７６に連通している。
【０１３５】
また、チューブ７４の内腔に連通しているポンプ６０１の内部流路７８は、位置ｂで、２つに分岐し、そのうちの一方の内部流路７８は、一方のポンプ室７６に連通し、他方の内部流路７８は、他方のポンプ室７６に連通している。
【０１３６】
すなわち、ポンプ室７６の下端側は、内部流路７７を介してチューブ７３の内腔に連通し、上端側は、内部流路７８を介してチューブ７４の内腔に連通している。
【０１３７】
ポンプ６０１の流入口６１１および流出口６１２の近傍には、それぞれ、一方向にのみ液体（非電解水）を通過させる一方向弁６３１および６３２が設置されている。
【０１３８】
一方向弁６３１は、流入口６１１側に配置され、図１２中下側から上側に向ってのみ液体を通過させるように構成されている。また、一方向弁６３２は、流出口６１２側に配置され、図１２中下側から上側に向ってのみ液体を通過させるように構成されている。
【０１３９】
モータ６６の回転軸６６１の先端部には、ギヤ６７が固定されており、このギヤ６７には、回転可能に設置されたギヤ６５が噛合している。
【０１４０】
ロッド６４の基端部（図１２中右側の端部）は、このギヤ６５の回転中心から偏心した位置に回動可能に設置され、先端部（図１２中左側の端部）は、ピストン６２に回動可能に設置されている。
【０１４１】
なお、一対のロッド６４、６４の基端部の位置は、ギヤ６５上で互いに１８０°ずれている。このため、一方のピストン６２と他方のピストン６２の周期が半周期ずれる。すなわち、一方のピストン６２が先端に位置しているとき、他方のピストンは、基端に位置し、逆に、一方のピストン６２が基端に位置しているとき、他方のピストンは、先端に位置する。
【０１４２】
このようなポンプ６０１では、モータ６６が駆動してギヤ６７が所定方向に回転すると、ギヤ６５が所定方向に回転し、このギヤ６５とともにロッド６４の図１２中右側の端部も回動し、このロッド６４の図１２中左側の端部が図１２中左右方向に往復動する。すなわち、ギヤ６５（モータ６６の回転軸６６１）の回転運動がピストン６２の往復運動に変換され、図１３に示すように、ピストン６２は、シリンダ６１内を図１３中左右方向に往復動する。
【０１４３】
ピストン６２の往復動により、ダイヤフラム７５がポンプ室７６の容積を増減し、これと一方向弁６３１、６３２の作用とにより、容器２４内の被電解水２５が側孔付チューブ２３、チューブ７３、７４内および内部流路３１を経て電解部４へ移送される。
【０１４４】
そして、後述する電解部４において前記被電解水２５が電気分解され、電解水が得られる。
【０１４５】
この電解水は、前記ポンプ６０１の作動により、ノズル５から脈動的に（脈動流として）噴射される。
【０１４６】
図１１に示すように、電解部４は、内部流路３１の途中に形成された電解槽４０と、電解槽４０内に対向して配置された板状の陽極４１および陰極４２よりなる電極対と、電極対への通電回路４３とで構成されている。
【０１４７】
通電回路（給電手段）４３は、電源（直流電源）４４と、電極対へ供給する電流を制御する電流制御回路４５と、スイッチ４６とで構成されている。電源４４のプラス端子は、電流制御回路４５を介して陽極４１へ接続され、電源４４のマイナス端子は、陰極４２へ接続されている。
【０１４８】
スイッチ４６は、操作部３の基端側にボタン３４と連携した作動片４７を有している。この作動片４７は、図示しないバネにより基端方向へ付勢され、常開スイッチを構成している。
【０１４９】
図１１に示すように、スイッチ４６が開状態では、電極対への通電はなされない。また、ボタン３４を押すと、ボタン３４の先端面により作動片４７が先端方向へ押圧されて移動し、スイッチ４６は、閉状態となる。これにより、電流制御回路４５が作動し、電極対へ所定の電流（電圧）が供給される。
【０１５０】
また、前述した実施例と同様に、通電回路４３は、前述したポンプ６０１のモータ６６への通電回路としても機能しており、陽極４１、陰極４２間に通電がなされたときには、同時にモータ６６への通電がなされてポンプ６０１が作動し、被電解水２５の送液、電解水２６の生成および噴出がなされ、陽極４１、陰極４２間に通電がなされないときには、モータ６６への通電もなされず、ポンプ６０１は停止する。
【０１５１】
この電解水供給装置１によれば、図１〜図５に示す前述した電解水供給装置１と同様の効果が得られる。
【０１５２】
以上、本発明の電解水供給装置を図示の各実施例に基づいて説明したが、本発明は、これらに限定されるものではなく、各部の構成は、同様の機能を有する任意の構成のものに置換することができる。
【０１５３】
また、本発明の電解水供給装置は、生体、特に、患部やＣＡＰＤ等における留置カテーテルの経皮開口部、各種医療器具等の消毒、殺菌（除菌）に用いる場合の他、例えば、手指、皮膚、口腔内、傷口（創傷部）、人工肛門の出口部等の洗浄、消毒や、日常の手洗い等に適用することもできる。また、利用分野は、医療用に限らず、例えば、食品用、農業用、工業用、家庭用等、あらゆる分野、場所および対象物に利用することができる。
【０１５４】
【実施例】
１．電解水供給装置の条件（実施例２、３、６、１０、１１、参考例１、４、５、７、８、９、比較例１および２）
図１〜図５に示す構成の電解水供給装置を製造した。この電解水供給装置において、所定の構成部材を変更することにより、ノズルから噴射する電解水の脈動数、打力の平均値、流量（噴出流量）を表１に示すように設定した（実施例２、３、６、１０、１１、参考例１、４、５、７、８、９）。
【０１５５】
また、ノズルから電解水の定常流を噴射する電解水供給装置を製造した（比較例１）。
【０１５６】
また、ノズルから生理食塩水の脈動流を噴射する電解水供給装置を製造した（比較例２）。
【０１５７】
打力の平均値および脈動数は、それぞれ、図７に示す測定方法により測定した値である。
【０１５８】
また、用いた被電解水は、塩酸を添加した０．９％塩化ナトリウム水溶液（ｐＨ：３．０）であり、噴射された電解水は、有効塩素濃度：５０ｐｐｍ、ｐＨ：５．５のものであった。
【０１５９】
２．実験
次に、電解水供給装置の消毒・除菌効果を確認するための実験を行った。
【０１６０】
１ｃｍ×１ｃｍの大きさに切除したラット表皮に０．５ｍｍの長さの傷を付け、その傷の内側に、大腸菌（菌数：２×１０⁵個）を付着させ、該ラット表皮を平面上に固定し、該ラット表皮の表面から垂直に１５ｃｍ離れた位置にノズルの先端が位置するように電解水供給装置を固定した。
【０１６１】
次に、レバー３３を操作してポンプ６および電解部４を作動し、ノズル５より電解水を噴射し、その噴流をラット表皮の創傷部に衝突させ、消毒・除菌を行った。この操作を前記実施例２、３、６、１０、１１、参考例１、４、５、７、８、９、比較例１および２でそれぞれ行った。

BACKGROUND OF THE INVENTION
  The present invention relates to an electrolyzed water supply device for supplying electrolyzed water for disinfection and sterilization (disinfection), for example.In placeRelated.
[0002]
[Prior art]
For example, it is generally known that electrolyzed water produced by electrolysis is useful in fields such as agriculture and food.
[0003]
Electrolyzed water has excellent disinfection and disinfection action and high safety. Therefore, in order to prevent food poisoning etc. in general households, household items such as kitchenware, baby goods, toys, cloths, furniture, toilets, etc. It has begun to be used for disinfection and sterilization of all rooms such as bathrooms, bedrooms, and living rooms.
[0004]
Furthermore, it has begun to be used for disinfection and sterilization of the human body, in particular, washing and disinfection of fingers.In recent years, it has been used in the medical field, for example, skin, wounds, affected areas, incisions, percutaneous openings of indwelling catheters, It is being studied for use in sterilization and disinfection of stomas (colostomy) and anus.
[0005]
In order to increase the electric conductivity of the electrolyzed water, such electrolyzed water is added with a solute that generates ions upon dissolution, such as sodium chloride, potassium chloride, magnesium chloride, calcium carbonate, etc., and an acid for adjusting the pH. It can be obtained by electrolyzing the added water (electrolyzed water).
[0006]
By the way, when such electrolyzed water is brought into contact with an organic substance, its activity is reduced, and the sterilizing / disinfecting effect is easily lost. Therefore, for example, when electrolyzed water is supplied to an uneven part such as a skin wound part to disinfect and disinfect it, the electrolyzed water comes into contact with the skin wound exudate and body fluid such as blood and reaches the bottom of the recess. There is a problem that it has been inactivated before and disinfection and sterilization become insufficient. And in order to prevent this, it is necessary to use a lot of electrolyzed water.
[0007]
In addition, when a wound part of a human body is washed using a washing liquid having no bactericidal power such as physiological saline, there is a high possibility that bacteria or the like are present in the washing liquid (spray liquid). There is a risk of secondary infection to areas other than the wound site.

DETAILED DESCRIPTION OF THE INVENTION
  Hereinafter, the electrolyzed water supply device of the present inventionPlaceThe present invention will be described in detail with reference to the preferred embodiments shown in the accompanying drawings.
[0027]

It is a side view. For convenience of explanation, the right side in FIGS. 1 to 5 is referred to as “base end”, the left side is referred to as “tip”, the upper side is referred to as “upper end”, and the lower side is referred to as “lower end”.
[0028]
The pulsation in the present invention means that the flow rate (flow velocity) of the liquid changes periodically, and as a result, the stress applied to the object by the liquid discharged from the nozzle changes periodically.
[0029]
As shown in FIGS. 1 and 2, an electrolyzed water supply device (electrolyzed water injection device) 1 according to the present invention includes a storage unit 2 that stores electrolyzed water and an operation unit 3 that performs an operation for ejecting electrolyzed water. And electrolyzing (electrolyzing) the electrolyzed water to make electrolyzed water, the nozzle 5 for ejecting the electrolyzed water generated in the electrolyzing unit 4, and the liquid feed for connecting the reservoir 2 and the nozzle 5 A passage 7 and a pump 6 are provided. The pump 6 serves as a liquid feeding means for feeding the electrolyzed water 25 along the liquid feeding path 7 and a pulsating means for jetting the electrolytic water from the nozzle 5 in a pulsating manner. Hereinafter, these will be described.
[0030]
The reservoir 2 is composed of a container 21. The container 21 may be hard or soft, but in the case of the present embodiment, for example, the container 21 is made of a hard material composed of various hard resins, metals, glass, ceramics, and the like. In some cases, the container 21 may have a vent portion (not shown) or a vent portion having a hydrophobic filter.
[0031]
Although the capacity | capacitance of the container 21 is not specifically limited, Considering size reduction of an apparatus, about 100-2000 ml is preferable and about 150-500 ml is more preferable.
[0032]
As shown in FIG. 4, a predetermined amount of electrolyzed water 25 is stored inside the container 21. The electrolyzed water 25 is water containing salts such as sodium chloride, potassium chloride, calcium chloride, and magnesium chloride. The electrolyzed water 25 preferably contains an acid such as hydrochloric acid, acetic acid, ascorbic acid, succinic acid, or citric acid.
[0033]
Further, the electrolyzed water 25 may contain various additives such as pH adjusting buffer, phosphate, carbonate and the like as required. Hereinafter, the electrolyzed water 25 will be described as a sodium chloride aqueous solution.
[0034]
An L-shaped connector 71 is installed on the lid portion 211 of the container 21. The connector 71 passes through the lid portion 211.
[0035]
A proximal end portion of a tube 70 described later is connected to the distal end portion of the connector 71.
[0036]
On the other hand, the lower end portion of the connector 71 is connected to the upper end portion of the pipe 72, and the lower end portion of the pipe 72 is immersed in the electrolyzed water 25.
[0037]
The liquid feeding path 7 is formed by the lumen of the pipe 72, the lumen of the connector 71, the lumen of the tube 70, and the internal flow path 31 of the operation unit main body 30 described later.
[0038]
As shown in FIGS. 2 and 3, the operation unit 3 includes an operation unit main body 30 having an internal flow path 31 and a lever 33 that is rotatably installed with respect to the operation unit main body 30.
[0039]
A grip portion 32 for gripping with a hand is formed in the lower portion of the operation portion main body 30. The lever 33 is urged in the distal direction, that is, in a direction away from the grip portion 32 by an urging means such as a torsion spring (not shown) installed near the rotation fulcrum.
[0040]
Further, the electrolysis section 4 is built in the operation section main body 30, and a nozzle 5 communicating with the internal flow path 31 is formed (or connected) at the distal end portion of the operation section main body 30.
[0041]
In addition, the operation unit body 30 is provided with a pump 6 that serves as both a liquid feeding unit and a pulsating unit.
[0042]
The distal end of the tube 70 is connected to the proximal end of the operation unit main body 30 so that the lumen communicates with the internal flow path 31. The tube 70 has flexibility, for example, polymer materials such as polyolefin, such as polyvinyl chloride, polyethylene, polypropylene, and ethylene-vinyl acetate copolymer (EVA), polyamide, polyester, silicone rubber, and polyurethane. It consists of
[0043]
The pump 6 is disposed between the nozzle 5 and the electrolysis unit 4 and in the vicinity of the electrolysis unit 4. Thereby, electrolysis water can be pulsated (pulsatingly injected) with high accuracy without being affected by the compliance of the tube 70. In the present invention, needless to say, the pump 6 may be disposed at a position other than the above.
[0044]
As shown in FIGS. 3 and 5, the pump 6 in the present embodiment is a piston pump, and is installed in the middle of the internal flow path 31. The cylinder 61 communicating with the internal flow path 31 and the cylinder 61 are reciprocated. It comprises a moving piston 62, a motor 66, a power transmission means comprising a rod 64, gears 65 and 67, and a casing 60 for housing them.
[0045]
The cylinder 61 is installed such that the inlet 611 is located on the proximal end side and the outlet 612 is located on the distal end side.
[0046]
A pair of one-way valves 631 and 632 that allow liquid (electrolyzed water) to pass through only in one direction are installed inside the cylinder 61. The one-way valve 631 is disposed on the inflow port 611 side, and is configured to allow liquid to pass only from the lower side to the upper side in FIG. The one-way valve 632 is disposed on the outlet 612 side, and is configured to allow liquid to pass only from the upper side to the lower side in FIG.
[0047]
A gear 67 is fixed to the tip end of the rotating shaft 661 of the motor 66, and a gear 65 that is rotatably installed meshes with the gear 67.
[0048]
One end (upper side in FIG. 5) of the rod 64 is rotatably installed at a position eccentric from the rotation center of the gear 65, and the other end (lower side in FIG. 5) rotates around the piston 62. It is installed movably.
[0049]
In such a pump 6, when the motor 66 is driven and the gear 67 rotates in a predetermined direction, the gear 65 rotates clockwise in FIG. 5, and the upper end of the rod 64 in FIG. Then, the lower end of the rod 64 in FIG. 5 reciprocates in the vertical direction in FIG. That is, the rotational movement of the gear 65 (the rotating shaft 661 of the motor 66) is converted into the reciprocating movement of the piston 62, and the piston 62 reciprocates in the cylinder 61 in the vertical direction in FIG.
[0050]
By the operation of the pump 6, the electrolyzed water 25 in the container 21 is transferred to the operation unit 3 through the pipe 72, the connector 71 and the tube 70.
[0051]
In the present invention, the pump is not limited to a piston pump, and any pump that can generate a pulsating flow can be used. For example, a diaphragm type pump (diaphragm pump) is suitable.
[0052]
The electrolysis unit 4 includes an electrolysis tank 40 formed in the middle of the internal flow path 31, an electrode pair composed of a plate-like anode 41 and a cathode 42 disposed facing the electrolysis tank 40, and energization of the electrode pair Circuit 43.
[0053]
The electrolytic cell 40 is a non-diaphragm electrolytic cell that does not have a diaphragm between the anode 41 and the cathode 42. As a result, the configuration of the apparatus can be further simplified as compared with the case where an electrolytic cell having a diaphragm is used, and an alkaline waste liquid is not generated. There is an advantage that it can be generated. In the present invention, it goes without saying that an electrolytic cell having a diaphragm may be used.
[0054]
As the anode 41 and the cathode 42 installed in the electrolytic cell 40, for example, a titanium metal plate plated with platinum can be used, but is not limited to this configuration.
[0055]
The energization circuit (power supply means) 43 includes a power source (DC power source) 44, a current control circuit 45 that controls a current supplied to the electrode pair, and a switch 46. A positive terminal of the power supply 44 is connected to the anode 41 via the current control circuit 45, and a negative terminal of the power supply 44 is connected to the cathode 42.
[0056]
The switch 46 has an operating piece 47 that protrudes toward the lever 33 on the distal end side of the grip portion 32. The operating piece 47 is urged toward the distal end by a spring (not shown) to constitute a normally open switch.
[0057]
As shown in FIG. 2, when the switch 46 is in the open state, the electrode pair is not energized. As shown in FIG. 3, when the lever 33 is grasped and the lever 33 is rotated in the proximal direction, that is, in the direction approaching the grip portion 32, the operating piece 47 is moved in the proximal direction by the proximal end surface of the lever 33. The switch 46 is pressed and moved, and the switch 46 is closed. As a result, the current control circuit 45 is activated, and a predetermined current (voltage) is supplied to the electrode pair.
[0058]
The energization circuit 43 also functions as an energization circuit for the motor 66 of the pump 6 described above. That is, the lead wire 68 connected to the minus terminal of the motor 66 is connected to the minus terminal of the power source 44, and the lead wire 69 connected to the plus terminal of the motor 66 is connected to the power source 44 via the current control circuit 45. Is connected to the positive terminal.
[0059]
Therefore, when energization is performed between the anode 41 and the cathode 42, the motor 66 is energized at the same time, the pump 6 is operated, the electrolyzed water 25 is fed, and the electrolyzed water 26 is generated and ejected. When no current is supplied between the cathodes 42, no current is supplied to the motor 66, and the pump 6 stops.
[0060]
In place of the current control circuit 45 or in combination with the current control circuit 45, for example, a power supply control circuit, a voltage control circuit, or the like can be used.
[0061]
In addition, the current control circuit, the voltage control circuit, and the power supply control circuit may have a function capable of independently controlling the electrode pair side and the motor 66 side, for example.
[0062]
In such an electrolysis unit 4, energization is performed between the anode 41 and the cathode 42, and in this state, when the electrolyzed water 25 sent by the operation of the pump 6 passes through the electrolytic cell 4, the electrolyzed water 25 is Electrolysis is performed and hypochlorous acid (HOCl) is generated on the anode 41 side by the reaction represented by the following formula, and sodium hydroxide (NaOH) and hydrogen gas (H₂And electrolyzed water 26 containing them is obtained.
[0063]
[Chemical 1]

[0064]
[Chemical 2]

[0065]
The electrolyzed water 26 is ejected from the nozzle 5 in a pulsating manner (as a pulsating flow) by the operation of the pump 6.
[0066]
That is, when the piston 62 moves from the lower side to the upper side in FIG. 5, the inside of the cylinder 61 is depressurized, so that the electrolyzed water 26 generated in the electrolysis unit 4 passes through the one-way valve 631 from the inlet 611 and is hollow. Inhaled into part 613.
[0067]
Next, when the piston 62 moves from the upper side to the lower side in FIG. 5, the inside of the cylinder 61 is pressurized, whereby the electrolytic water 26 in the hollow portion 613 passes through the one-way valve 632 and protrudes from the outlet 612 ( Discharged) and sprayed from the nozzle 5.
The above operation is repeated, and the electrolyzed water 26 is jetted from the nozzle 5 in a pulsating manner.
[0068]
FIG. 8 is a graph showing the change over time of the striking force of the electrolyzed water 26 sprayed from the nozzle 5. The conditions are the orifice diameter at the tip of the nozzle 5 (diameter of the electrolyzed water outlet) r = 0.06 cm and the average value L of the electrolyzed water 26 L = 2.8 ml / sec. The method for measuring the striking force will be described in detail later.
[0069]
As shown in the figure, when the electrolyzed water 26 is jetted from the nozzle 5 in a pulsating manner, the flow rate of the electrolyzed water 26 ejected from the nozzle 5 changes, thereby changing the striking force of the electrolyzed water 26. (It becomes a rough wave shape).
[0070]
The jet (pulsating flow) of the injected electrolyzed water 26 collides with an object to be sterilized / sterilized (for example, the surface of a living body) to perform sterilization / sterilization.
[0071]
When the grip of the lever 33 is released, the energization of the electrode pair and the energization of the motor 66 are stopped, and the generation and injection of the electrolyzed water 26 are stopped.
[0072]
When the electrolyzed water 25 in the container 21 becomes empty, the electrolyzed water 25 can be replenished in the container 21 and the use can be continued.
[0073]
The pulsating flow includes a continuous flow when the electrolyzed water 26 is continuously injected as shown in FIG. 9, and an intermittent flow when the electrolyzed water 26 is intermittently injected as shown in FIG. Is included.
[0074]
The electrolyzed water 26 sprayed from the nozzle 5 preferably has a pH of about 3 to 7, more preferably about 4 to 6.5, and more preferably about 4.5 to 5.5. preferable. FIG. 6 shows effective chlorine contained in the electrolyzed water 26, that is, hypochlorous acid (HOCl), hypochlorite ion (OCl).^-), Chlorine molecules (Cl₂) Shows the change of the abundance ratio with respect to pH. As shown in FIG. 6, when the pH is too low, the abundance ratio of chlorine molecules in the electrolyzed water tends to increase, and the effective chlorine amount becomes unstable. Conversely, when the pH is too high, The abundance ratio of chlorite ions tends to increase, and in either case, the disinfection / sterilization effect (especially the bactericidal effect in the presence of protein) is reduced. Therefore, the pH of the electrolyzed water is preferably in the above range.
[0075]
The electrolyzed water 26 injected from the nozzle 5 preferably has an effective chlorine concentration of about 1 to 200 ppm, more preferably about 30 to 100 ppm, and particularly preferably about 50 to 80 ppm. If the effective chlorine concentration is too low, the disinfection / sterilization effect (especially the bactericidal effect in the presence of protein) will not be sufficiently exhibited when the batting force described below is relatively low, and if the effective chlorine concentration is too high, When used on the human body, safety is reduced. Therefore, when the application is not intended for the human body, the effective chlorine concentration may exceed 200 ppm.
[0076]
The electrolyzed water 26 sprayed from the nozzle 5 preferably has a pulsation number of about 60 to 3000 times / minute, more preferably about 100 to 2500 times / minute.
[0077]
If the number of pulsations is less than 60 times / minute, the improvement in the disinfection / sterilization effect is not sufficient when the batting force described later is relatively weak or the flow rate is relatively small, and 3000 times / Even if it exceeds the minute, no further improvement in disinfection / disinfection effect is seen.
[0078]
Moreover, it is preferable that the average value of the striking force of the electrolyzed water 26 injected from the nozzle 5, that is, the average value of the striking force at a position 3 cm away from the tip of the nozzle 5 is about 0.5 to 11 gf.
[0079]
If the average value of the striking force is less than 0.5 gf, the disinfection / sterilization effect is not sufficiently improved when the flow rate described later is relatively small, and the average value of the striking force exceeds 11 gf. However, there is no further improvement in disinfection / disinfection effect.
[0080]
In addition, when using the electrolyzed water supply apparatus 1 of this invention for disinfection and sterilization of a human body (living body), the average value of the said striking force is preferable about 0.5-9 gf, and about 0.5-7 gf is still more preferable. About 0.7 to 4 gf is particularly preferable. If the average value of the striking force is too high, there is a possibility of giving great pain depending on the part of the human body.
[0081]
Moreover, it is preferable that the average value of the flow volume (flow volume per jet nozzle) of the electrolyzed water 26 injected from the nozzle 5 is about 0.3 to 7 ml / second, and is about 1 to 5 ml / second. Is more preferable.
[0082]
If the average value of the flow rate is less than 0.3 ml / second, the improvement of the disinfection / sterilization effect may not be sufficient when the batting force is relatively weak, and the average value of the flow rate is Even if it exceeds 7 ml / sec, no further improvement in disinfection and sterilization effect is observed, and waste of electrolyzed water increases.
[0083]
In the present invention, electrolyzed water is jetted in a pulsating manner, and in particular, disinfection and sterilization under the above-described conditions (especially disinfection and sterilization of human wounds) is effective with a small amount of electrolyzed water (cleaning solution). Can be sterilized and disinfected.
[0084]
In this case, there are no living bacteria in the electrolyzed water, or the number of bacteria is small, and the portion of the wound that has been subjected to the electrolyzed water is disinfected and disinfected by the electrolyzed water, so that it is acceptable. Even if the striking force is increased within the range of pain, there is almost no invasion of living bacteria into the tissue inside the wound by electrolyzed water, and the tissue inside the wound is fully disinfected.・ Can be sterilized.
[0085]
In addition, the electrolyzed water used for disinfection and sterilization, and the splash of electrolysis water that splashed back from the wound (skin wound) during sterilization and sterilization are sterilized by its own sterilizing power. Secondary infection by these can be prevented, and safety is high.
[0086]
Even when electrolytic water splashes (spray liquid) bounced off the human wound (skin wound) scatter around, the secondary spray is sterilized by the sterilizing power of the electrolytic water. Infection can be prevented.
[0087]
Here, a method of measuring the striking force (average value) and the number of pulsations of the electrolyzed water 26 injected from the nozzle 5 will be described.
[0088]
FIG. 7 is a diagram illustrating a method for measuring the striking force and the number of pulsations. The load cell 10 has a receiving plate (made of plastic) 11. The load cell 10 is connected to a computer 12, and a monitor 13 is connected to the computer 12.
The stress applied to the backing plate 2 is measured by the load cell 10, and the data is input to the computer 12 and stored so as to correspond to time. The measurement of stress is repeatedly performed almost continuously or at very short time intervals, and the computer 12 performs predetermined arithmetic processing (calculation of an average value of stress, calculation of the number of pulsations per unit time, etc.).
[0089]
In addition, when a graph with a vertical axis representing the striking force (stress) and a horizontal axis representing time (a graph showing a change with time of the striking force) is created, when the electrolyzed water jet 8 is a pulsating flow, the graph is approximately In the case of a wave shape (see FIG. 8) and the electrolyzed water jet 8 is a steady flow, the graph is substantially linear.
[0090]
At the time of measurement, the nozzle 5 is fixed so that the tip of the nozzle 5 is located at a distance of 3 cm from the receiving plate 12, and a jet (jet) 8 of electrolyzed water sprayed horizontally from the tip opening of the nozzle 5 is used. It strikes the receiving plate 12 vertically. As a result, a striking force (stress) due to the jet 8 is applied to the backing plate 11, and the data is input to the computer 12, and the computer 12 performs a predetermined calculation process, that is, the obtained value, that is, the average value of the striking force and one minute. The number of pulsations per hit is displayed on the monitor 13.
[0091]
The values obtained from the data from the point of time when a stable state is obtained after 5 seconds from the start of the injection of electrolyzed water from the nozzle 5 are taken as the average value of the striking force and the number of pulsations in the present invention, respectively. In this case, the time from the local maximum point of the graph showing the change in the hitting force to the next local maximum point through the local minimum point (minimum value) decreased by 10% or more with respect to the local maximum value is obtained once. It is the time of pulsating flow.
[0092]
The electrolyzed water supply device 1 of the present invention is suitable for use in disinfecting / disinfecting sites having small irregularities on the surface, such as skin and skin defects, or sites having fine gaps.

That is, by spraying electrolyzed water in a pulsating manner, the electrolyzed water can reach the back (bottom) and narrow gaps of the small concave and convex portions without being deactivated, and can be disinfected and disinfected.
[0094]
Moreover, when electrolyzed water is injected pulsatingly and the pulsation number, the average value of the striking force, the average value of the flow rate, and the like are set within the above-described preferable ranges, the disinfection / sterilization effect is further improved.
[0095]
In the electrolyzed water supply device 1, the pulsating flow of the electrolyzed water 26 ejected from the nozzle 5 may be buffered by a pipe line (flow path) from the supply port of the electrolyzed water 25 to the nozzle 5. Therefore, by appropriately setting the shape and size (inner diameter) of the pipeline, the form, shape and size (opening area) of the nozzle 5 outlet, and the flow rate of the electrolyzed water 26, the above-described range is obtained. Get a pulsating flow of. Further, by appropriately setting these conditions, the striking force in the above-described range can be obtained.
[0096]
The form (injection form) and the like of the nozzle 5 are not particularly limited and may be any form as long as a pulsating flow can be obtained, but the electrolyzed water 26 is ejected into one or more lines (as a jet). What is obtained is preferable, and what can discharge the electrolyzed water 26 in one linear form (direct injection) is more preferable.
[0097]
In addition, the nozzle 5 may be another one or two such as a form in which the electrolyzed water 26 is ejected in a shower form, a form in which the electrolyzed water 26 is sprayed in a mist form, or the like in which the jet flow is swung or rotated. The thing which can be switched to the above injection form may be sufficient, or the thing which can use these several injection forms together may be used.

Done. As a result, the required amount of electrolyzed water 26 can be generated and used when necessary, and the electrolyzed water 26 rich in activity can always be supplied, and excellent disinfection and sterilization effects can be stably obtained. .
[0100]
In the electrolyzed water supply device 1, since the electrolyzed water 26 is ejected while the lever 33 is being gripped, the cumulative ejection amount of the electrolyzed water 26 can be adjusted by the time during which the lever 33 is gripped.
[0101]
In addition, the operation unit 3 is small and light, and is separated from the storage unit 2 and is connected by a flexible tube 70 so that its posture and position can be freely set. The operation of supply to the site can be performed very easily.
[0102]
The entire electrolyzed water supply device 1 is also small and light. Therefore, it is suitable for carrying.
For example, it is suitable for the patient to carry the electrolyzed water supply device 1 and periodically disinfect and disinfect the affected part of the patient, the percutaneous opening of the indwelling catheter, and the like.

The container 24 is soft in the case of the present embodiment, and examples of the constituent material thereof include vinyl chloride, polyethylene, polypropylene, and polyester.
[0124]
The container 24 is connected to the attachment portion 36 of the operation portion main body 30 by the connection portion 22, and is deformed by the suction of the electrolyzed water 25 by the pump 601.
[0125]
The connection part 22 of the container 24 is formed with a hole (through hole) 221 into which the upper end part of the tube 23 with side holes is inserted.
[0126]
The tube 23 with a side hole is immersed in the electrolyzed water 25 in the container 24, and the upper end portion thereof is inserted into (fixed to) the hole 221 of the connection portion 22.
[0127]

In addition, by using the tube 23 with a side hole, the electrolyzed water 25 in the container 24 can be sucked up without waste.
[0129]
The liquid feeding path 7 is formed by the lumen of the tube 23 with side holes, the lumen of the tube 73, the lumen of the tube 74 and the internal flow path 31.
[0130]
The pump 601 is disposed between the storage unit 2 and the electrolysis unit 4. By configuring the tube 74 with a hard material, the pump 601 can pulsate (pulsately inject) the electrolyzed water with high accuracy. In the present invention, needless to say, the pump 601 may be disposed at a position other than the above.
[0131]
As shown in FIGS. 12 and 13, the pump 601 in this embodiment is a diaphragm pump, and is installed in the middle of the liquid supply path 7, and a pair of pump chambers 76 and 76 that communicate with the liquid supply path 7. A pair of cylinders 61, 61 connected to the pump chambers 76, 76, a pair of pistons 62, 62 reciprocating in the cylinders 61, 61, an inner wall surface of the pump chambers 76, 76, and an outer wall surface of the pistons 62, 62 And a pair of diaphragms 75 and 75, a motor 66, and a power transmission means including a pair of rods 64 and 64 and gears 65 and 67.
[0132]
The pair of pump chambers 76 and 76, the pair of cylinders 61 and 61, the pair of pistons 62 and 62, the pair of diaphragms 75 and 75, the pair of rods 64 and 64, and the like have the same structure. Therefore, one of these will be described.
[0133]
A pump chamber 76 is connected to one end side (front end side) of the cylinder 61, and an opening is formed on the other end side (base end side).
[0134]
The internal flow path 77 of the pump 601 communicating with the lumen of the tube 73 branches into two at the position a, and one of the internal flow paths 77 communicates with one pump chamber 76 and the other. The internal flow path 77 communicates with the other pump chamber 76.
[0135]
Further, the internal flow path 78 of the pump 601 communicating with the lumen of the tube 74 branches into two at the position b, and one of the internal flow paths 78 communicates with one pump chamber 76, The other internal flow path 78 communicates with the other pump chamber 76.
[0136]
That is, the lower end side of the pump chamber 76 communicates with the lumen of the tube 73 via the internal flow path 77, and the upper end side communicates with the lumen of the tube 74 via the internal flow path 78.
[0137]
In the vicinity of the inlet 611 and the outlet 612 of the pump 601, one-way valves 631 and 632 that allow liquid (non-electrolyzed water) to pass only in one direction are installed.
[0138]
The one-way valve 631 is disposed on the inlet 611 side, and is configured to allow liquid to pass only from the lower side to the upper side in FIG. The one-way valve 632 is disposed on the outlet 612 side, and is configured to allow liquid to pass only from the lower side to the upper side in FIG.
[0139]
A gear 67 is fixed to the tip end of the rotating shaft 661 of the motor 66, and a gear 65 that is rotatably installed meshes with the gear 67.
[0140]
The base end portion (right end portion in FIG. 12) of the rod 64 is rotatably installed at a position eccentric from the rotation center of the gear 65, and the tip end portion (left end portion in FIG. 12) is the piston 62. It is installed in a rotatable manner.
[0141]
Note that the positions of the base end portions of the pair of rods 64 and 64 are shifted from each other by 180 ° on the gear 65. For this reason, the cycle of one piston 62 and the other piston 62 is shifted by a half cycle. That is, when one piston 62 is located at the distal end, the other piston is located at the proximal end. Conversely, when one piston 62 is located at the proximal end, the other piston is located at the distal end. To position.
[0142]
In such a pump 601, when the motor 66 is driven and the gear 67 rotates in a predetermined direction, the gear 65 rotates in a predetermined direction, and the end portion on the right side of the rod 64 in FIG. The left end of the rod 64 in FIG. 12 reciprocates in the left-right direction in FIG. That is, the rotational motion of the gear 65 (the rotating shaft 661 of the motor 66) is converted into the reciprocating motion of the piston 62, and as shown in FIG. 13, the piston 62 reciprocates in the left-right direction in FIG.
[0143]
Due to the reciprocating motion of the piston 62, the diaphragm 75 increases or decreases the volume of the pump chamber 76, and by this and the action of the one-way valves 631, 632, the electrolyzed water 25 in the container 24 becomes the side-holed tube 23, the tube 73, It is transferred to the electrolysis unit 4 through 74 and the internal flow path 31.
[0144]
And in the electrolysis part 4 mentioned later, the said to-be-electrolyzed water 25 is electrolyzed and electrolyzed water is obtained.
[0145]
This electrolyzed water is ejected from the nozzle 5 in a pulsating manner (as a pulsating flow) by the operation of the pump 601.
[0146]
As shown in FIG. 11, the electrolysis unit 4 includes an electrode pair composed of an electrolytic cell 40 formed in the middle of the internal flow path 31, and a plate-like anode 41 and a cathode 42 disposed facing the electrolytic cell 40. And an energization circuit 43 to the electrode pair.
[0147]
The energization circuit (power supply means) 43 includes a power source (DC power source) 44, a current control circuit 45 that controls a current supplied to the electrode pair, and a switch 46. A positive terminal of the power supply 44 is connected to the anode 41 via the current control circuit 45, and a negative terminal of the power supply 44 is connected to the cathode 42.
[0148]
The switch 46 has an operating piece 47 linked to the button 34 on the proximal end side of the operation unit 3. The operating piece 47 is urged in the proximal direction by a spring (not shown) to constitute a normally open switch.
[0149]
As shown in FIG. 11, when the switch 46 is in the open state, the electrode pair is not energized. When the button 34 is pressed, the operating piece 47 is pressed and moved in the distal direction by the distal end surface of the button 34, and the switch 46 is closed. As a result, the current control circuit 45 is activated, and a predetermined current (voltage) is supplied to the electrode pair.
[0150]
Similarly to the above-described embodiment, the energization circuit 43 also functions as an energization circuit to the motor 66 of the pump 601 described above. When energization is performed between the anode 41 and the cathode 42, the energization circuit 43 is simultaneously supplied to the motor 66. And the pump 601 is actuated to feed the electrolyzed water 25, generate and eject the electrolyzed water 26, and when the anode 41 and the cathode 42 are not energized, the motor 66 is not energized. The pump 601 stops.
[0151]
According to this electrolyzed water supply apparatus 1, the same effect as the electrolyzed water supply apparatus 1 described above shown in FIGS.
[0152]
As mentioned above, although the electrolyzed water supply apparatus of this invention was demonstrated based on each Example of illustration, this invention is not limited to these, The structure of each part is a thing of arbitrary structures which have the same function Can be substituted.
[0153]

[0154]
【Example】
1. Conditions of electrolyzed water supply device (Examples 2, 3, 610, 11, Reference Examples 1, 4, 5,7,8, 9, Comparative Examples 1 and 2)
  The electrolyzed water supply apparatus having the configuration shown in FIGS. 1 to 5 was manufactured. In this electrolyzed water supply device, by changing predetermined constituent members, the number of pulsations of electrolyzed water ejected from the nozzle, the average value of the striking force, and the flow rate (jet flow rate) were set as shown in Table 1 (Example) 2, 3, 610, 11, Reference Examples 1, 4, 5,7,8, 9).
[0155]
Moreover, the electrolyzed water supply apparatus which injects the steady flow of electrolyzed water from a nozzle was manufactured (comparative example 1).
[0156]
Moreover, the electrolyzed water supply apparatus which injects the pulsating flow of the physiological saline from a nozzle was manufactured (comparative example 2).
[0157]
The average value and the number of pulsations of the striking force are values measured by the measuring method shown in FIG.
[0158]
The electrolyzed water used was a 0.9% sodium chloride aqueous solution (pH: 3.0) to which hydrochloric acid was added, and the injected electrolyzed water had an effective chlorine concentration of 50 ppm and a pH of 5.5. Met.
[0159]
2. Experiment
Next, an experiment was conducted to confirm the disinfection / sterilization effect of the electrolyzed water supply device.
[0160]
The rat epidermis excised to a size of 1 cm × 1 cm was scratched with a length of 0.5 mm, and Escherichia coli (the number of bacteria: 2 × 10 10) was placed inside the wound.^FiveThe rat epidermis was fixed on a flat surface, and the electrolyzed water supply device was fixed so that the tip of the nozzle was positioned 15 cm vertically away from the surface of the rat epidermis.
[0161]
  Next, the lever 33 was operated to operate the pump 6 and the electrolysis unit 4, and electrolyzed water was ejected from the nozzle 5, and the jet flow collided with the wound portion of the rat epidermis to perform disinfection and sterilization. This operation is performed in the above-described Examples 2, 3, and 6.10, 11, Reference Examples 1, 4, 5,7,8, 9 and Comparative Examples 1 and 2, respectively.
[0162]
  Examples 2, 3, and 6 above10, 11, Reference Examples 1, 4, 5,7,About each of 8, 9 and the comparative example 1, the disinfection and disinfection effect after 10 second progress from the supply start of electrolysis water was confirmed. The disinfection / disinfection effect was evaluated by the magnitude of the disinfection rate calculated by the following formula (I).
[0163]
Disinfection rate% = (1−viable count after disinfection / viable count before disinfection) × 100 (I)
Moreover, about each of Example 5 and Comparative Example 2, the washing | cleaning liquid after washing | cleaning was collect | recovered and the viable count in the washing | cleaning liquid was measured.
[0164]
3. Experimental result
  Examples 2, 3, and 610, 11, Reference Examples 1, 4, 5,7,Table 1 below shows the sterilization rates obtained for each of 8, 9 and Comparative Example 1.
[0165]
[Table 1]

[0166]
  Also,Reference Example 5Table 2 below shows the number of viable bacteria obtained for each of Comparative Example 2 and Comparative Example 2.
[0167]
[Table 2]

[0168]
As shown in Table 1, it was confirmed that an excellent disinfecting and disinfecting effect can be obtained by pulsating the electrolyzed water from the nozzle.
[0169]
On the other hand, in the case of the steady flow (Comparative Example 1), the inside of the wound could not be sufficiently cleaned, and a sufficient disinfection / disinfection effect could not be obtained.
[0170]
In addition, by spraying electrolyzed water from the nozzle in a pulsatile manner, the average value of the striking force is 0.5 to 11 gf, and the average value of the flow rate is 0.3 to 7 ml / second, so that higher disinfection and sterilization can be achieved. It was confirmed that an effect was obtained.
[0171]
Moreover, as shown in Table 2, in the case of the comparative example 2 which used the physiological saline as a washing | cleaning liquid, there is no bactericidal effect and a large amount of microbe exists in the washing | cleaning liquid (including the droplet of a washing | cleaning liquid) after washing | cleaning. There is a risk of secondary infection.
[0172]
  In contrast, electrolyzed water was used as the cleaning liquid.Reference Example 5In this case, it was confirmed that bacteria were not present in the cleaning liquid after cleaning (including the spray of the cleaning liquid) and could be used safely.
[0173]
In addition, when the electrolyzed water supply apparatus of the structure shown in FIGS. 11-13 was manufactured and the same experiment as the above was conducted, the same favorable result as the above was obtained.
[0174]
【The invention's effect】
As described above, according to the present invention, the sterilization / sterilization effect inherent in the electrolyzed water can be further improved by pulsating the electrolyzed water from the nozzle, and a smaller amount of electrolysis can be achieved. High disinfection and sterilization effect can be obtained with water. In other words, a high disinfection / disinfection effect can be obtained in a shorter time.
[0175]
And the high disinfection and disinfection effect can be acquired with a further small amount of electrolyzed water by making the average value of the striking force of electrolyzed water, and the average value of flow volume into the value mentioned above. That is, a high disinfection / disinfection effect can be obtained in a shorter time.
[0176]
In particular, when it is configured so that the generation of electrolyzed water and the ejection of electrolyzed water are performed synchronously, the required amount of electrolyzed water can be generated and used when necessary. It can be supplied without waste, and the efficiency and stability of disinfection and sterilization are high.
[0177]
Moreover, the electrolyzed water supply device of the present invention is suitable for reducing the size and weight of the device, and is excellent in operability such as an operation of ejecting electrolyzed water. In particular, when the operation unit is installed away from the storage unit, the operation unit is smaller and lighter and has a wide degree of freedom of movement, so that the operability is further improved and the operation unit is stored. In the case of being integrated with the unit or using a non-diaphragm electrolytic cell, the apparatus can be further miniaturized and the structure can be simplified.
[0178]
For this reason, the electrolyzed water supply device of the present invention is suitable for carrying. For example, when applied to medical use, not only doctors and nurses but also patients themselves supply electrolyzed water to their bodies. It becomes easy to disinfect and disinfect by spraying.
