　しかしながら、多忙を極める医療現場において、医療従事者が、チューブに設けられた継手の雄部材と雌部材を誤接続する場合があった。この場合、異なる薬液や気体を投与または送られた患者は、本来投与されるべき薬液または気体の欠乏や、異なる薬液または気体による作用により生死に関わる危険な状態に陥るケースがあるという問題があった。
　本発明は、上述の問題に鑑みてなされたものであり、雄部材と雌部材の誤接続を防止することができる継手および継手セットを提供することを目的とする。
　本発明は、上記目的を達成するために、互いに接続される雄部材と雌部材からなる医療用の継手であって、前記雄部材は、内部に流路を有する雄部材本体と、前記雄部材本体の周囲に設けられた雄部材側周壁部とを備え、前記雌部材は、内部に流路を有する雌部材本体と、前記雌部材本体の周囲に設けられた雌部材側周壁部とを備え、前記雄部材側周壁部と前記雌部材側周壁部は、先端部に複数の咬合凸部および咬合凹部が周方向に沿って交互に形成されており、前記雄部材と前記雌部材が接続される際、前記雄部材本体と前記雌部材本体が嵌合するとともに、前記雄部材側周壁部と前記雌部材側周壁部の咬合凸部および咬合凹部が互いに咬合することを特徴とする。
　これによれば、雄部材本体と雌部材本体が嵌合するとともに、雄部材側周壁部と雌部材側周壁部の咬合凸部および咬合凹部が互いに咬合するため、雄部材と雌部材を強固に接続することができる。また、雄部材と雌部材が接続された際、雄部材本体と雌部材本体が雄部材側周壁部および雌部材側周壁部に周囲を覆われた状態となるため、外部からの埃、塵、あるいは手術時等に生じる各種液体などから継手を防護することができる。さらに、継手の雄部材の雌部材が接続される際、雄部材側周壁部と雌部材側周壁部の咬合凸部および咬合凹部の形状、大きさ、位置、個数の少なくともいずれか一つが異なる場合、該継手の雄部材と雌部材は正しく接続されないため、継手の雄部材と雌部材の誤接続を防止することができる。
　また、前記雄部材本体は、前記雄部材側周壁部の咬合凸部よりも軸方向に突出する高さに形成されてもよい。これによれば、雄部材と雌部材が接続される際、雄部材本体の先端部を雌部材本体の先端部に合わせて嵌合させ易くなる。
　また、前記雄部材側周壁部の咬合凸部は、前記雄部材本体との間に所定の空間が設けられており、前記雄部材と前記雌部材が接続される際、前記雄部材側周壁部の咬合凸部と前記雄部材本体の間の当該空間に前記雌部材の前記雌部材本体が嵌入するものとなされてもよい。これによれば、雄部材と雌部材が接続された際、雄部材側周壁部の咬合凸部が雌部材本体の外周面を径方向外側から支承するため、継手の雄部材と雌部材をより強固に接続することができる。
　また、前記雄部材側周壁部の咬合凸部は、内周面に係合凸部が形成される一方、前記雌部材本体は、外周面に係合凹部が形成され、前記雄部材と前記雌部材が接続される際、前記雄部材側周壁部の係合凸部と前記雌部材本体の係合凹部が互いに係合してもよい。これによれば、雄部材と雌部材が接続される際、雄部材側周壁部の係合凸部と雌部材本体の係合凹部が互いに係合するため、継手の雄部材と雌部材をより強固に接続することができる。
　また、前記雌部材側周壁部の咬合凸部は、前記雄部材と前記雌部材が接続された際に前記雌部材本体の外周面に当接する位置に設けられてもよい。これによれば、雄部材と雌部材が接続された際、雌部材側周壁部の咬合凸部が雄部材側周壁部の咬合凸部と共に雌部材本体の外周面を径方向外側から支承するため、継手の雄部材と雌部材をより強固に接続することができる。
　また、前記継手が複数組設けられた継手セットであって、各組の継手は、前記雄部材側周壁部と前記雌部材側周壁部の咬合凸部および咬合凹部の形状、大きさ、位置、個数の少なくともいずれか一つが互いに異なるように形成されてもよい。これによれば、雄部材側周壁部と前記雌部材側周壁部の咬合凸部および咬合凹部の形状、大きさ、位置、個数のいずれも一致する正規の組の雄部材と雌部材については、雄部材側周壁部と雌部材側周壁部の咬合凸部と咬合凹部が互いに咬合するため、雄部材と雌部材を正しく接続することができる。一方、雄部材側周壁部と前記雌部材側周壁部の咬合凸部および咬合凹部の形状、大きさ、位置、個数の少なくともいずれか一つが異なる非正規の組の雄部材と雌部材については、雄部材側周壁部と雌部材側周壁部の咬合凸部と咬合凹部が互いに咬合し得ないため、雄部材と雌部材を正しく接続することができない。これにより正規の組の雄部材と雌部材の接続を許容する一方、非正規の組の雄部材と雌部材の接続を妨げるため、医療現場における様々な用途や目的などに応じて複数組の継手を安全に使い分けることが可能となる。
　また、各組の継手は、前記雄部材側周壁部と前記雌部材側周壁部に同一の色が着色され、各組の継手の間において該色が互いに異なるように着色されてもよい。これによれば、正規の組の雄部材と雌部材を視覚的に判別し得るため、継手の雄部材と雌部材の誤接続をより一層防止することができる。
　本発明によれば、雄部材本体と雌部材本体が嵌合するとともに、雄部材側周壁部と雌部材側周壁部の咬合凸部および咬合凹部が互いに咬合するため、雄部材と雌部材を強固に接続することができる。また、雄部材と雌部材が接続された際、雄部材本体と雌部材本体が雄部材側周壁部および雌部材側周壁部に周囲を覆われた状態となるため、外部からの埃、塵、あるいは手術時等に生じる各種液体などから継手を防護することができる。さらに、継手の雄部材と雌部材が接続される際、雄部材側周壁部と雌部材側周壁部の咬合凸部および咬合凹部の形状、大きさ、位置、個数の少なくともいずれか一つが異なる場合、該継手の雄部材と雌部材は正しく接続されないため、継手の雄部材と雌部材の誤接続を防止することができる。

　本発明に係る継手が複数組設けられた継手セットの実施形態について図１～図６を参照しつつ説明する。
　本継手セットは、図１および図２に示すように、第１の組の継手１ａ、第２の組の継手１ｂ、第３の組の継手１ｃの３組の継手が設けられた継手セットである。
　なお、本明細書では、第１の組の継手１ａ、第２の組の継手１ｂ、第３の組の継手１ｃにおいて同一の構成部材には同一の数字を付すとともに、第１の組の継手１ａの構成部材の数字に「ａ」の文字を付し、第２の組の継手１ｂの構成部材の数字に「ｂ」の文字を付し、第３の組の継手１ｃの構成部材の数字に「ｃ」を付すものとする。以下では、まず第１の組の継手１ａについて詳細に説明し、次に第２の継手１ｂおよび第３の組の継手１ｃについて第１の組の継手１ａとの相違点を中心に説明する。
　前記第１の組の継手１ａは、図３に示すように、互いに接続されるチューブＣ１、Ｃ２の境界部分に設けられる雄部材１０ａと雌部材２０ａから構成される。
　前記雄部材１０ａは、チューブＣ１に連結され、内部に薬液や気体等の流体が流される流路Ｐ１が形成された雄部材本体１１ａと、雄部材本体１１ａの周囲に設けられた雄部材側周壁部１２ａを備えている。一方、雌部材２０ａは、チューブＣ２に連結され、内部に薬液や気体等の流体が流される流路Ｐ２が形成された雌部材本体２１ａと、雌部材本体２１ａの周囲に設けられた雌部材側周壁部２２ａと、雌部材側周壁部２２ａのチューブＣ２側に図示略の枠体等に掛け止められる掛止部材２３ａとを備えている。
　前記雄部材本体１１ａと雌部材本体２１ａは、互いに嵌合し得る長さおよび径の円筒状に形成されており、雄部材１０ａと雌部材２０ａが接続される際、雄部材本体１１ａが雌部材本体２１ａに嵌合するものとなされている。
　また、前記雄部材本体１１ａは、先端の周縁部にテーパ状の傾斜面１１１ａが設けられ、雌部材本体２１ａに嵌合させ易くなっている。
　また、前記雄部材本体１１ａは、外周面に周方向に延びる環状の溝が形成され、当該溝にパッキン等のシール部材１１２ａが嵌め込まれ、シール部材１１２ａにより雌部材本体２１ａに密着状態に嵌合するようになっている。
　また、前記雄部材本体１１ａは、雄部材側周壁部１２ａの咬合凸部１２２ａよりも軸方向に突出する高さに形成されており、雄部材本体１１ａの先端部を雌部材本体２１ａの先端部に合わせて嵌合させ易くなっている。
　また、前記雌部材本体２１ａは、図５（ｂ）に示すように、外周面において周方向に延び径方向内側に陥凹した係合凹部２１１ａが形成されている。この係合凹部２１１ａは、雄部材１０ａと雌部材２０ａが接続される際、後述の雄部材側周壁部１２ａの係合凸部１２４ａと係合する。
　前記雄部材側周壁部１２ａは、周壁部本体１２１ａの先端部から軸方向に延びるように形成された４個の咬合凸部１２２ａと、咬合凸部１２２ａの間に形成された４個の咬合凹部１２３ａとが設けられ、これら咬合凸部１２２ａと咬合凹部１２３ａが周方向に沿って交互に配置されている。一方、前記雌部材側周壁部２２ａは、周壁部本体２２１ａの先端部から軸方向に延びるように形成された４個の咬合凸部２２２ａと、咬合凸部２２２ａの間に形成された４個の咬合凹部２２３ａとが設けられ、これら咬合凸部２２２ａと咬合凹部２２３ａが周方向に沿って交互に配置されている。なお、雌部材側周壁部２２ａは、雄部材側周壁部１２ａよりも外径が若干大きくなるように形成されている。
　前記雄部材側周壁部１２ａの咬合凸部１２２ａと前記雌部材側周壁部２２ａの咬合凹部２２３ａは、互いに形状（輪郭）、大きさ（軸方向の長さ及び周方向の幅）、位置（周方向および径方向の位置）、個数（４個）のいずれも一致するように形成されている。一方、前記雄部材側周壁部１２ａの咬合凹部１２３ａと前記雌部材側周壁部２２ａの咬合凸部２２２ａも、互いに互いに形状（輪郭）、大きさ（軸方向の長さ及び周方向の幅）、位置（周方向および径方向の位置）、個数（４個）のいずれも一致するように形成されている。なお、第１の組の継手１ａにおいて、雄部材側周壁部１２ａの咬合凸部１２２ａと雌部材側周壁部２２ａの咬合凸部２２２ａは、周方向の幅比が概ね２対１となるように形成されている。
　而して、雄部材１０ａと雌部材２０ａが接続される際、雄部材側周壁部１２ａの咬合凸部１２２ａが雌部材側周壁部２２ａの咬合凹部２２３ａに嵌るとともに、雌部材側周壁部２２ａの咬合凸部２２２ａが雄部材側周壁部１２ａの咬合凹部１２３ａに嵌ることにより、雄部材側周壁部１２ａと雌部材側周壁部２２ａの咬合凸部１２２ａ、２２２ａおよび咬合凹部１２３ａ、２２３ａが互いに隙間なく咬合する。
　なお、前記雄部材側周壁部１２ａの咬合凸部１２２ａは、雄部材本体１１ａとの間に所定の空間が設けられており、雄部材１０ａと雌部材２０ａが接続された際、雄部材側周壁部１２ａの咬合凸部１２２ａと雄部材本体１１ａの間の当該空間に雌部材２０ａの雌部材本体２１ａが嵌入するようになっている。これによれば、雄部材１０ａと雌部材２０ａが接続された際、雄部材側周壁部１２ａの咬合凸部１２２ａが雌部材本体２１ａの外周面を径方向外側から支承するため、継手１ａの雄部材１０ａと雌部材２０ａをより強固に接続することができる。
　また、前記雄部材側周壁部１２ａの咬合凸部１２２ａは、図５（ｂ）に示すように、内周面に径方向内側に突出した係合凸部１２４ａが形成されている。この係合凸部１２４ａは、雄部材１０ａと雌部材２０ａが接続される際、上述のように雌部材本体２１ａの係合凹部２１１ａと係合することにより、継手１ａの雄部材１０ａと雌部材２０ａをより強固に接続することができる。
　また、前記雌部材側周壁部２２ａの咬合凸部２２２ａは、雌部材本体２１ａとの間に若干の隙間が設けられる位置に設けられており、雄部材１０ａと雌部材２０ａが接続された際、雌部材本体２１ａが径方向外側に若干拡がることにより、雌部材本体２１ａの外周面に当接する。これによれば、雄部材１０ａと雌部材２０ａが接続された際、雌部材側周壁部２２ａの咬合凸部２２２ａが雄部材側周壁部１２ａの咬合凸部１２２ａと共に雌部材本体２１ａの外周面を径方向外側から支承するため、継手１ａの雄部材１０ａと雌部材２０ａをより強固に接続することができる。なお、前記雌部材側周壁部２２ａの咬合凸部２２２ａは、雌部材本体２１ａの外周面にあらかじめ当接する位置に設けられてもよい。
　前記掛止部材２３ａは、図３および図５（ａ）に示すように、雌部材側周壁部２２ａに隣接して設けられた第１掛止部２３１ａと、第１掛止部２３１ａのチューブＣ２側に設けられた第２掛止部２３２ａと、第１の掛止部２３１ａに対して第２掛止部２３２ａを軸方向に進退させるためのネジ部２３３ａとを備える。これによれば、第１掛止部２３１ａと第２掛止部２３２ａの間に枠体等を配置した状態において、第２掛止部２３２ａをネジ部２３３ａ上を第１掛止部２３１ａ側に螺進させれば、第１掛止部２３１ａと第２掛止部２３２ａにより枠体等を挟着することができ、継手１ａの全体を枠体に掛け止めることが可能となる。
　なお、図４および図５は、第２掛止部２３２ａを取り外した状態を表している。また、図中のＨ１、Ｈ２は、チューブＣ１、Ｃ２と雄部材１０ａ、雌部材１０ｂの接続部分を被覆するカバー部材である。
　以上の第１の継手１ａの雄部材１０ａと雌部材２０ａの構造によれば、雄部材１０ａと雌部材２０ａが接続される際、雄部材本体１１ａと雌部材本体２１ａが嵌合するとともに、雄部材側周壁部１２ａと雌部材側周壁部２２ａの咬合凸部１２２ａ、２２２ａおよび咬合凹部１２３ａ、２２３ａが互いに咬合するため、雄部材１０ａと雌部材２０ａを強固に接続することができる。
　また、雄部材１０ａと雌部材２０ａが接続された際、雄部材本体１１ａと雌部材本体２１ａが雄部材側周壁部１２ａおよび雌部材側周壁部２２ａに周囲を覆われた状態となるため、外部からの埃、塵、あるいは手術時等に生じる各種液体などから継手を防護することができる。
　さらに、継手１ａの雄部材１０ａと雌部材２０ａが接続される際、雄部材側周壁部１２ａと雌部材側周壁部２２ａの咬合凸部１２２ａ、２２２ａおよび咬合凹部１２３ａ、２２３ａの形状、大きさ、位置、個数の少なくともいずれか一つが異なる場合、該継手１ａの雄部材１０ａと雌部材２０ａは正しく接続されないため、継手１ａの雄部材１０ａと雌部材１０ａの誤接続を防止することができる。
　次に、第２の組の継手１ｂについて説明する。
　前記第２の組の継手１ｂにおいて、前記雄部材側周壁部１２ｂは、周壁部本体１２１ｂの先端部に各２個の咬合凸部１２２ｂおよび咬合凹部１２３ｂが周方向に沿って交互に形成されている。一方、前記雌部材側周壁部２２ｂは、周壁部本体２２１ｂの先端部に各２個の咬合凸部２２２ｂおよび咬合凹部２２３ｂが周方向に沿って交互に形成されている。
　前記雄部材側周壁部１２ｂの咬合凸部１２２ｂと前記雌部材側周壁部２２ｂの咬合凹部２２３ｂは、互いに形状（輪郭）、大きさ（軸方向の長さ及び周方向の幅）、位置（周方向および径方向の位置）、個数（２個）のいずれも一致するように形成されている。一方、前記雄部材側周壁部１２ｂの咬合凹部１２３ｂと前記雌部材側周壁部２２ｂの咬合凸部２２２ｂも、互いに形状（輪郭）、大きさ（軸方向の長さ及び周方向の幅）、位置（周方向および径方向の位置）、個数（２個）のいずれも一致するように形成されている。なお、第２の組の継手１ｂにおいて、雄部材側周壁部１２ｂの咬合凸部１２２ｂと雌部材側周壁部２２ｂの咬合凸部２２２ｂは、周方向の幅比が概ね３対１となるように形成されている。
　而して、雄部材１０ｂと雌部材２０ｂが接続される際、雄部材側周壁部１２ｂの咬合凸部１２２ｂが雌部材側周壁部２２ｂの咬合凹部２２３ｂに嵌るとともに、雌部材側周壁部２２ｂの咬合凸部２２２ｂが雄部材側周壁部１２ｂの咬合凹部１２３ｂに嵌ることにより、雄部材側周壁部１２ｂと雌部材側周壁部２２ｂの咬合凸部１２２ｂ、２２２ｂおよび咬合凹部１２３ｂ、２２３ｂが互いに隙間なく咬合する。
　次に、第３の組の継手１ｃについて説明する。
　前記第３の組の継手１ｃにおいて、前記雄部材側周壁部１２ｃは、周壁部本体１２１ｃの先端部に各３個の咬合凸部１２２ｃおよび咬合凹部１２３ｃが周方向に沿って交互に形成されている。一方、前記雌部材側周壁部２２ｃは、周壁部本体２２１ｃの先端部に各３個の咬合凸部２２２ｃおよび咬合凹部２２３ｃが周方向に沿って交互に形成されている。
　前記雄部材側周壁部１２ｃの咬合凸部１２２ｃと前記雌部材側周壁部２２ｃの咬合凹部２２３ｃは、互いに形状（輪郭）、大きさ（軸方向の長さ及び周方向の幅）、位置（周方向および径方向の位置）、個数（３個）のいずれも一致するように形成されている。一方、前記雄部材側周壁部１２ｃの咬合凹部１２３ｃと前記雌部材側周壁部２２ｃの咬合凸部２２２ｃも、互いに形状（輪郭）、大きさ（軸方向の長さ及び周方向の幅）、位置（周方向および径方向の位置）、個数（３個）のいずれも一致するように形成されている。なお、第３の組の継手１ｃにおいて、雄部材側周壁部１２ｃの咬合凸部１２２ｃと雌部材側周壁部２２ｃの咬合凸部２２２ｃは、周方向の幅比が概ね２対１となるように形成されている。
　而して、雄部材１０ｃと雌部材２０ｃが接続される際、雄部材側周壁部１２ｃの咬合凸部１２２ｃが雌部材側周壁部２２ｃの咬合凹部２２３ｃに嵌るとともに、雌部材側周壁部２２ｃの咬合凸部２２２ｃが雄部材側周壁部１２ｃの咬合凹部１２３ｃに嵌ることにより、雄部材側周壁部１２ｃと雌部材側周壁部２２ｃの咬合凸部１２２ｃ、２２２ｃおよび咬合凹部１２３ｃ、２２３ｃが互いに隙間なく咬合する。
　このように、各組の継手１ａ、１ｂ、１ｃは、雄部材側周壁部１２ａ、１２ｂ、１２ｃと雌部材側周壁部２２ａ、２２ｂ、２２ｃの咬合凸部１２２ａ、１２２ｂ、１２２ｃ、２２２ａ、２２２ｂ、２２２ｃおよび咬合凹部１２３ａ、１２３ｂ、１２３ｃ、２２３ａ、２２３ｂ、２２３ｃの形状、大きさ、位置、個数の全てが互いに異なるように形成されている。
　これによれば、図６に示すように、雄部材側周壁部１２と雌部材側周壁部２２の咬合凸部１２２、２２２および咬合凹部１２３、２２３の形状、大きさ、位置、個数のいずれも一致する正規の組の雄部材１０と雌部材２０（例えば図６における雄部材１０ａと雌部材２０ａ）については、雄部材側周壁部１２と雌部材側周壁部２２の咬合凸部１２２、２２２と咬合凹部１２３、２２３が互いに咬合するため、雄部材１０と雌部材２０を正しく接続することができる。一方、雄部材側周壁部１２と雌部材側周壁部２２の咬合凸部１２２、２２２および咬合凹部１２３、２２３の形状、大きさ、位置、個数の少なくともいずれか一つが異なる非正規の組の雄部材１０と雌部材２０（例えば図６における雄部材１０ｂ、１０ｃと雌部材２０ａ）については、雄部材側周壁部１２と雌部材側周壁部２２の咬合凸部１２２、２２２と咬合凹部１２３、２２３が互いに咬合し得ないため、雄部材１０と雌部材２０を正しく接続することができない。これにより正規の組の雄部材１０と雌部材２０の接続を許容する一方、非正規の組の雄部材１０と雌部２０の接続を妨げるため、医療現場における様々な用途や目的などに応じて複数組の継手１を安全に使い分けることが可能となる。
　なお、各組の継手１は、雄部材側周壁部１２と雌部材側周壁部２２に同一の色が着色され、各組の継手１の間において該色（例えば、第１の組の継手１ａは青色、第２の組の継手１ｂは緑色、第３の組の継手１ｃは赤色）が互いに異なるように着色されてもよい。この場合、正規の組の雄部材１０と雌部材２０を視覚的に判別し得るため、継手１の雄部材１０と雌部材２０の誤接続をより一層防止することができる。
　上記実施形態では、前記咬合凸部１２２、２２２および前記咬合凹部１２３、２２３は、周方向に等間隔に２つ～４つ並んで設けられているものとして説明したが、これに限られず、その他の形状、大きさ、位置、個数であってもよい。要は、各組の継手１は、咬合凸部１２２、２２２および咬合凹部１２３、２２３は、形状、大きさ、位置、個数の少なくともいずれか一つが互いに異なるように形成されることにより、正規の組の雄部材１０と雌部材２０については正しく接続できる一方、非正規の組の雄部材１０と雌部材２０については正しく接続できないものであればよい。
　以上、図面を参照して本発明の実施形態を説明したが、本発明は、図示した実施形態のものに限定されない。図示された実施形態に対して、本発明と同一の範囲内において、あるいは均等の範囲内において、種々の修正や変形を加えることが可能である。
