Description

【０００１】
【発明の属する技術分野】
本発明は、薬液を予め充填、保管しておき使用時に包装から取り出して直ぐに使用する容器兼用注射器において、使用時に容器兼用注射器のシリンダの後端部に嵌着されている指掛用の本体グリップに装着して使用する補助グリップに関するものである。
【０００２】
【従来の技術】
前記容器兼用注射器は、病医院内において煩雑な操作をすることなく、包装から取り出して直ぐに使用できるので、利便性に優れ、医師や看護婦の作業の軽減に大変に役立ち、このため、多くの病医院で採用されるようになって来ている。
従来の容器兼用注射器は、ガラス製の円筒状のシリンダの先端と後端に、注射針を取り付ける筒先部とフィンガーグリップ（本体グリップ）とを、それぞれ、合成樹脂で作製して嵌着することにより、前記シリンダの素材であるガラスの医薬品に対する安全性を最大限に利用すると共に、その弱点であるガラスの破損のし易さを、前記シリンダの両端の弾力性を有する合成樹脂製の部品（筒先、本体グリップ）で補っている。
【０００３】
特に、本体グリップは、容器兼用注射器の滅菌、薬液充填、組立、包装等の作業の際、ガラス製シリンダの端面を破損から守りながら整列や機械での搬送、位置決め等の工程に重要な役割を果たしている。しかし、それらの工程の中で容器兼用注射器のハンドリングに必要なスペース、作業の安定性、包装の大きさ等の点を考慮して、本体グリップは、その形状や寸法を限られた範囲のものに定められ、特に寸法はあまり大きくできない制限がある。
【０００４】
容器兼用注射器のシリンダに設けたフィンガーグリップの大きさが小さいと、該容器兼用注射器を使用する際、使用者の指が本体グリップに十分に引っ掛けるかけることができず、安定した状態で容器兼用注射器を支持して注射することができないおそれがあるので、使用時に、シリンダに設けた本体グリップに対し、別に用意した本体グリップより大きな補助グリップを装着して注射することが提案され、そのような補助グリップが、例えば、特許第２８１４９８３号公報、特開平８−７３１号公報、登録実用新案第３００６４１９号公報等により知られている。
【０００５】
これらの公報に記載されている補助グリップは、いずれも、容器兼用注射器のシリンダと一体に形成された本体グリップに装着して使用するものであり、そのフランジ部の外形は、前記シリンダの直径方向の両側に突出した指掛部を長径とし、該指掛部と直角な方向の部分を短径とした楕円形状、矩形状、もしくはそれらに近い方向性を有する形状に形成されている。
【０００６】
【発明が解決しようとする課題】
一般に、病医院では、医師や看護婦が注射をする際、容器兼用注射器の筒先に取り付けた注射針の刃先を確認して、その刃面を上に向けた位置で注射をしているが、そのときには、フィンガーグリップ（補助グリップ）の指掛部の位置が注射のし易い都合の良い位置になっていなければならない。
しかしながら、前記のように補助グリップが方向性を有する形状に形成されていると、補助グリップを容器兼用注射器のシリンダの本体グリップに無造作に装着した場合、補助グリップの指掛部の位置が、注射針の刃面を上に向けた状態で注射に都合の良い位置になるとは限らない。
【０００７】
このため、医師や看護婦は、容器兼用注射器に従来の補助グリップを使用して注射をする際には、常に、注射針の刃面位置を確認して、その位置に指掛部もしくは指掛部に直角な方向の部分の位置が合うようにして補助グリップを本体グリップに装着するか、もしくは補助グリップを本体グリップに装着後軸回りに回転させ、指掛部やその直角な方向の部分の位置を注射針の刃面位置に合わせる操作をしなければならない。
したがって、従来の補助グリップでは、注射に際して注射針の刃面と指掛部等の位置を合わせるための無駄な作業が必要となり、円滑で能率的な注射が行えない問題があった。
【０００８】
本発明は、上記事情に鑑みてなされたものであって、容器兼用注射器の使用時にフィンガーグリップの指掛部の指保持性が確保されると共に、注射針の刃面と指掛部等との位置合わせ作業が不要であり、注射が円滑、能率的に行える利便性を良くした容器兼用注射器の補助グリップを提供することを目的とする。
【０００９】
【課題を解決するための手段】
本発明は、前記課題を解決するために、以下の点を特徴としている。
すなわち、請求項１に係る容器兼用注射器の補助グリップは、容器兼用注射器のシリンダの後端部に円筒状部を介して嵌着した本体グリップに装着して使用する補助グリップであって、外径が前記本体グリップに設けた指掛部より大径の円形に形成され、中心部に本体グリップの円筒状部を挿通する装着穴が設けられている平板状のフランジ部材と、該フランジ部材の後面に一体に結合して設けられ、前記本体グリップの指掛部を挿入する装着溝が形成されると共に、中心部に前記シリンダに挿入されるプランジャロッドの直径より大径で、前記指掛部より小径の貫通穴が設けられている装着部材と、前記フランジ部材と装着部材とに設けられて前記装着穴と装着溝と貫通穴とを側方に開口し、前記フランジ部材と装着部材との本体グリップへの着脱を許容する開放部と、該開放部を経て前記フランジ部材と装着部材が本体グリップから離脱するのを防止する係止部とを備え、前記フランジ部材と装着部材はそれらの径方向の分割面で複数に分割された分割体からなり、フランジ部材と装着部材の少なくとも一方に、前記分割面のうちの１つの特定分割面側を常時離間して前記開放部を形成するように付勢して隣接する分割体を外周側で相互に連結するヒンジが設けられると共に、前記フランジ部材と装着部材の前記本体グリップへの脱着時に、前記特定分割面側における前記開放部を開閉すべくその両側に隣接する分割体を相互に連結、解除するようにしてなる前記係止部が設けられており、前記装着溝は、前記本体グリップにおける前記円筒状部の中心を通る対角線上にある指掛部の角部間の距離と同一とされた直径の環状溝に形成されていることを特徴とする。
【００１０】
前記容器兼用注射器の補助グリップにおいては、使用直前に、補助グリップを、その装着溝の位置が本体グリップの指掛部の位置に合う状態にして、フランジ部材と装着部材の開放部を通して横から本体グリップに装着すると、その装着状態が係止部を介して維持される。補助グリップの本体グリップからの取り外し時は、係止部に適度の力を加えてそれを弾性変形させて開放部を開いて、補助グリップを横方向に本体グリップから脱出させる。
【００１１】
この容器兼用注射器の補助グリップによれば、補助グリップが本体グリップの外側に装着されて使用されるものであるので、フランジ部材によって十分な大きさの指掛部としての面積が得られると共に、補助グリップのフランジ部材の外形形状が円形に形成されているので、容器兼用注射器の注射針の刃面を注射のし易い位置に向けても、本体グリップの指掛部の方向に関係なく、補助グリップは常に指掛けのし易い状態にあって指保持性が確保されるため、注射針の刃面と指掛部との位置合わせ作業が不要であり、注射を円滑、かつ能率的に行える。
【００１２】
また、本体グリップの指掛部に装着したときにフランジ部材の周囲に開放部が生じないので、容器兼用注射器の注射針の刃面を注射のし易い位置においた状態で使用者が指掛けを常に良好に行える。
【００１３】
さらに、この容器兼用注射器の補助グリップによれば、本体グリップに指掛部の方向を気にしないで、補助グリップを本体グリップに容易、迅速に装着できる。
【００１４】
請求項２に係る容器兼用注射器の補助グリップは、請求項１に記載の補助グリップにおいて、係止部は、特定分割面に隣接する２つの分割体の一方における分割面の近傍に設けられた凹溝と、他方における分割面の近傍に設けられ、前記凹溝に対し常時係合する側へ付勢され、かつ係脱可能な係合片とを備えていることを特徴とする。この容器兼用注射器の補助グリップによれば、補助グリップを本体グリップに装着した後に開放部を閉じて確実に本体グリップに支持させることができる。
【００１５】
請求項３に係る容器兼用注射器の補助グリップは、請求項２に記載の補助グリップにおいて、フランジ部材と装着部材は、合成樹脂材料からなり、分割体を連結するヒンジが自由状態で開放部を形成するように、かつ係合片が凹溝に係合される付勢状態になるように一体に成形してなることを特徴とする。この容器兼用注射器の補助グリップによれば、本体グリップへ横方向から簡単に着脱でき、容器兼用注射器の注射時に指掛部に開放部が生じない補助グリップを１つの成型品として容易に製作することができる。
【００１８】
請求項４に係る容器兼用注射器の補助グリップは、容器兼用注射器のシリンダの後端部に円筒状部を介して嵌着した本体グリップに装着して使用する補助グリップであって、外形が円形の周囲を所定間隔をあけて削り落とした多角形状の角部に円弧状部を残した形状とされ、中心部に本体グリップの円筒状部を挿通する装着穴が設けられているフランジ部材と、該フランジ部材の後面に一体に結合して設けられ、前記本体グリップの指掛部を挿入する装着溝が形成されると共に、中心部に前記シリンダに挿入されるプランジャロッドの直径より大径で、前記指掛部より小径の貫通穴が設けられている装着部材と、前記フランジ部材と装着部材とに設けられて前記装着穴と装着溝と貫通穴とを側方に開口し、前記フランジ部材と装着部材との本体グリップへの着脱を許容する開放部と、該開放部を経て前記フランジ部材と装着部材が本体グリップから離脱するのを防止する係止部とを備え、前記フランジ部材の装着穴は、前記本体グリップの円筒状部に嵌合する穴として形成され、前記係止部は、前記装着穴の開放部の内側位置において、開放部の開口寸法を前記本体グリップの円筒状部の直径寸法より小さくなるように、前記フランジ部材に開放部の両側から対向して突出させて設けた突起によって形成されると共に、該係止部の背部側には前記装着穴から延長するスリットが開放部に沿って設けられていることを特徴とするこの容器兼用注射器の補助グリップによれば、スリットによって係止部に弾力性が良好に付与され、本体グリップへの着脱が容易に行え、形状も単純であり、取扱が円滑にできる。
【００１９】
請求項５に係る容器兼用注射器の補助グリップは、請求項４に記載の補助グリップにおいて、装着溝は、本体グリップの指掛部が嵌合する直径の環状溝に形成され、その開口部側が該環状溝の直径の大きさで開放されていることを特徴とする。この容器兼用注射器の補助グリップによれば、本体グリップの指掛部の方向に関係なく、簡単に補助グリップを本体グリップに装着できる。
【００２１】
【発明の実施の形態】
以下、本発明の実施の形態に係る容器兼用注射器の補助グリップについて添付図面を参照して説明する。
先ず、補助グリップを装着して使用する容器兼用注射器１は、図４に示すように、ガラス製の円筒状のシリンダ２と、該シリンダ２の先端に嵌着した筒先３と、シリンダ２の後端に嵌着したフィンガーグリップ（本体グリップ）４と、シリンダ２の後端側からシリンダ２内に先端側を挿入されたプランジャロッド５とを備えている。前記筒先３は、詳細は図示しないが、その先端部が直接接着方式、ルアー・チップ方式、ルアー・ロック方式による注射針の取付部３ａとなっている。
【００２２】
また、図示しないが、前記シリンダ２内には、その先端側と後端側に挿入された一対のゴム製のストッパの間に薬液が充填され、前記プランジャロッド５の先端部が後端側のストッパにねじ込まれて連結されている。
前記本体グリップ４は、弾力があり高温による滅菌が可能な材質の合成樹脂からなり、円筒状部４ａの後端部にフランジ４ｂを一体に結合して構成され、前記円筒状部４ａがシリンダ２の後端に嵌着して設けられている。また、本体グリップ４は、そのシリンダ２への嵌着部に細いリブ等が設けられ、適度な摩擦の付与により嵌着力を高められていると共に、前記フランジ４ｂの中心穴部は、前記シリンダ２の内径より僅かに小さく形成されて、前記後端側のストッパがシリンダ２外へ抜け出るのを防止している。
【００２３】
また、前記本体グリップ４のフランジ４ｂは、図５、図６に示すように、正面視で矩形状に形成され、円筒状部４ａ（シリンダ２）の直径方向の両側に延長した長径部が指掛部４ｃ，４ｃとされ、該指掛部４ｃ，４ｃに直角な部分が前記円筒状部４ａに外接する円弧状の平滑面４ｄ，４ｄとされている。通常、本体グリップ４のシリンダ２の周方向における嵌着位置は、前記フランジ４ｂにおける一対の指掛部４ｃ，４ｃまたは平滑面４ｄ，４ｄの一方の位置（本体グリップ４の特定位置）が、前記注射針の刃面のシリンダ２の周方向における位置（刃面位置）と位相が一致する角度位置に設定されている。
【００２４】
次に、容器兼用注射器１に装着して使用する第１の実施の形態に係る補助グリップ１０は、合成樹脂材料で作製され、図１〜図３に示すように、外形が円形状をした平板からなるフランジ部材１１と、該フランジ部材１１の後面に一体に結合されて、前記容器兼用注射器１の本体グリップ４のフランジ４ｂが挿入される環状溝（装着溝）１２を内側に形成され、かつ外形が前記フランジ部材１１より小径の円形状をした装着部材１３とを備えている。前記環状溝１２は、その直径が前記本体グリップ４の指掛部４ｃの長さ寸法（正確には、本体グリップ４の円筒状部４ａの中心を通る対角線上にある指掛部４ｃ，４ｃの角部間の距離Ｌ（図６参照））と同一とされ、その溝幅が外周側で前記本体グリップ４のフランジ４ｂの幅に等しく、外周側から中心側に向けて徐々に僅かに広がる形状に形成されている。
【００２５】
また、前記フランジ部材１１と装着部材１３の中心部には、ほぼ同一直径の装着穴１１ａと貫通穴１３ａとが設けられている。前記装着穴１１ａの直径は、前記本体グリップ４の円筒状部４ａの外径より僅かに大きくされ、また、前記貫通穴１３ａの直径は、容器兼用注射器１のプランジャーロッド５の外径より大きく、前記環状溝１２の直径より小さく形成されていればよく、必ずしも前記装着穴１１ａと同一にしなくてもよい。
【００２６】
さらに、前記フランジ部材１１と装着部材１３は、それらの中心を通る直径方向の位置でそれらの軸方向に沿った分割面ｆで切断されて、それぞれ、一対の半円形部片（分割体）１１Ａ，１１Ｂ、１３Ａ，１３Ｂに分割されている。フランジ部材１１の各半円形部片１１Ａ，１１Ｂにおける一方の外周部（一端部）には、各半円形部片１１Ａ，１１Ｂの当接面（分割面）ｆ１側に凹部１１ｂ，１１ｃを対向して形成することによってヒンジとしての薄肉部１４が設けられ、該薄肉部１４によって各半円形部片１１Ａ，１１Ｂが相互に連結されている。前記フランジ部材１１と装着部材１３の半円形体片１１Ａ，１１Ｂ、１３Ａ，１３Ｂは、自由状態では前記薄肉部１４の弾力性によって薄肉部１４が設けられていない特定分割面ｆ２側（他端部側）が開口した開放部１７（図６参照）となっている。
【００２７】
一方、前記フランジ部材１１の各半円形部片１１Ａ，１１Ｂにおける他方の外周部には、各半円形部片１１Ａ，１１Ｂの当接面（特定分割面）ｆ２の近傍に位置して、一方の半円形部片１１ＡにＶ字状の凹溝１５が設けられ、他方の半円形部片１１Ｂに前記凹溝１５に係脱可能な係合片１６が設けられている。
前記凹溝１５と係合片１６とで前記フランジ部材１１と装着部材１３の開放部１７を開閉可能に連結し、補助グリップ１０を本体グリップ４に装着後にそこから不用意に離脱するのを防止する係止部１８を構成している。
【００２８】
前記係合片１６は、一方の半円形部片１１Ａ側に向けて突き出した突起部１６ａとその反対側に延長された押圧部１６ｂとを有し、中央部が他方の半円形部片１１Ｂの外周部における当接面の近傍に一体に結合されている。そして、前記係合片１６は、図５に示すように、各半円形部片１１Ａ，１１Ｂの当接面が当接されたときに、前記凹溝１５に前記突起部１６ａが突入するように常時付勢され、前記押圧部１６ｂをその付勢力に抗して押圧すると、突起部１６ａを凹溝１５から離脱できるようになっている。
【００２９】
前記補助グリップ１０においては、筒先３の取付部３ａに注射針を取り付けシリンダ２の後端にプランジャーロッド５を取り付けた容器兼用注射器１で注射をする際に、その注射の直前に補助グリップ１０を包装から取り出し、装着溝１２の位置が容器兼用注射器１の本体グリップ４のフランジ４ｂの位置に合う状態にして、図６に示すように、フランジ部材１１と装着部材１３の開放部１７を通して横から本体グリップ４ｂに被せるようにして装着する。
【００３０】
その際、前記開放部１７を閉じて前記特定分割面ｆ２で半円形部片１１Ａ，１１Ｂが当接された時点で係合片１６の突起部１６ａが凹溝１５内に突入し、その装着状態が維持される。補助グリップ１０を本体グリップ４に装着した状態で容器兼用注射器１で注射が終わったときは、前記係合片１６の押圧部１６ｂを押して突起部１６ａを凹溝１５から外して、前記半円形部片１１Ａ，１１Ｂを薄肉部１４を中心にして特定分割面ｆ２側を分離して前記開放部１７を開くと、補助グリップ１０は本体グリップ４から横方向に容易に取り外すことができ、繰り返し使用が可能である。
【００３１】
前記実施の形態の補助グリップ１０によれば、本体グリップ４の外側に装着されて使用されるものであるので、前記フランジ部材１１によって十分な大きさの指掛部としての面積が得られると共に、フランジ部材１１の外形形状が円形に形成されているので、容器兼用注射器１のシリンダ２を回転して注射針の刃面を注射のし易い位置（上向き位置）に向けても、本体グリップ４の指掛部４ｃの方向に関係なく、補助グリップ１０の指掛部（フランジ部材１１）が常に面積の広い指掛けのし易い状態とすることができる。
【００３２】
また、補助グリップ１０は、本体グリップ４に装着した後は、凹溝１５と係合片１６との係合で前記フランジ部材１１と装着部材１３の各半円形体片１１Ａ，１１Ｂ、１３Ａ，１３Ｂがしっかりと閉じた状態を維持されるので、前記装着後から医師による注射時まで安定した装着状態が保証され、容器兼用注射器１の取り扱い中に不用意に脱落するのを防止することができる。
したがって、注射の際の指保持性が確保され、注射針の刃面と本体グリップ４の指掛部４ｃとの位置合わせ作業が不要であり、注射を円滑に、能率良く行うことができる。
【００３３】
なお、前記補助グリップ１０は、合成樹脂材料に限らず他の材料で製作してもよいが、合成樹脂材料で製作すると、フランジ部材１１の半円形部片１１Ａ，１１Ｂを一端部でヒンジとしての薄肉部１４を介して連結し、該薄肉部１４の弾力性を利用して他端部側が開放される状態にされ、かつ係合片１６がその突起部１６ａを凹溝１５に突入する方向に弾力的に付勢された状態にされてなるフランジ部材１１と装着部材１３の各分割体１１Ａ，１１Ｂ、１３Ａ，１３Ｂを、射出成形等によって一体物の成型品として容易に製作することができる。
前記薄肉部１４に代えて、薄い金属製の板バネ等をインサート成形等により各半円形部片１１Ａ，１１Ｂに跨って埋め込むことによってヒンジを形成してもよく、同様に、係合片１６を可撓性の金属片等を半円形部片１１Ｂに埋め込んで構成してもよい。
【００３４】
また、前記補助グリップ１０では、前記装着部材１３をフランジ部材１１より小径に形成したが、これに限らず、同径に形成して両者を１つの円盤状に形成してもよく、また、前記ヒンジと、凹溝１５と係合片１６とからなる係止部１８をフランジ部材１１に設けたが、これに限らず、装着部材１３に設けたり、フランジ部材１１と装着部材１３の双方に跨って設けるようにしてもよい。
さらに、前記実施の形態の補助グリップ１０は、前記フランジ部材１１と装着部材１３とを分割面ｆで分割してなる２つの分割体としての半円形部片１１Ａ，１１Ｂ、１３Ａ，１３Ｂで構成されているので、構成が簡単になって好ましいが、これに限らず、３つ以上の分割体で構成することができる。この場合、１つの特定分割面側に係止部を設け、他の分割面側において各分割体の隣接するもの同士を相互にヒンジで連結するようにする。
【００３５】
次に、容器兼用注射器１に装着して使用する第２の実施の形態に係る容器兼用注射器の補助グリップ２０について図７〜９を参照して説明する。
前記補助グリップ２０は、合成樹脂材料で作製され、図７に示すように、外形が円形状をした平板からなるフランジ部材２１と、該フランジ部材２１の後面に一体に結合されて、前記容器兼用注射器１の本体グリップ４のフランジ４ｂが挿入される装着溝２２を内側に形成した外径がフランジ部材２１と同径の円形状の装着部材２３とを備えており、全体として１つの円盤状に形成されている。
【００３６】
前記装着溝２２は、正面視で矩形状に形成され、その長辺部の長さが前記本体グリップ４の指掛部４ｃの最大長さ寸法と同一とされ、その短辺部の長さが本体グリップ４の平滑面４ｄの最大幅寸法と同一とされ、本体グリップ４の各指掛部４ｃ，４ｃと一方の平滑面４ｄとに対し５点で外接するようになっている。また、前記装着溝２２の溝幅は、全体に平行であって、前記本体グリップ４のフランジ４ｂの厚さより僅かに大きく設定されている。
また、前記フランジ部材２１と装着部材２３の中心部には、装着穴２１ａと貫通穴２３ａとが設けられている。前記装着穴２１ａの直径は、前記本体グリップ４の円筒状部４ａの外径より僅かに大きくされ、また、前記貫通穴２３ａの直径は、容器兼用注射器１のプランジャーロッド５の外径より大きく、前記装着溝２２の短辺部の寸法より小さく形成されている。
【００３７】
前記フランジ部材２１と装着部材２３とには、それらの周方向における同一位置において、前記装着穴２１ａと装着溝２２と貫通穴２３ａとを側方に開口する開放部２１ｂ，２２ａ，２３ｂがそれぞれ設けられている。フランジ部材２１の開放部２１ｂはその開口寸法が前記装着穴２１ａの直径と同一とされ、装着部材２３の開放部２３ｂはその開口寸法が前記貫通穴２３ａの直径と同一とされており、前記容器兼用注射器１の本体グリップ４の円筒状部４ａとプランジャーロッド５を側方から装着穴２１ａと貫通穴２３ａに挿入できるようになっている。
【００３８】
また、前記装着溝２２の開放部２２ａは、その開口寸法が外端部（入口端部）で前記本体グリップ４の指掛部４ｃ，４ｃの最大長さ寸法より僅かに大きくされ、かつ内側に向けて徐々に小さくなるように傾斜されており、装着溝２２との交差部である内端部（内側位置）に、該装着溝２２の長辺部の寸法より開口寸法を小さくすべく一対の段差部（突起）２２ｂ，２２ｂが対向して設けられている。
前記段差部２２ｂ、２２ｂは、補助グリップ２０を本体グリップ４に装着後にそこから不用意に離脱するのを防止する係止部を構成している。
【００３９】
そして、前記本体グリップ４に対し補助グリップ２０を着脱する際に、補助グリップ２０に、小さな力を加えるだけで、その素材である合成樹脂材料の柔軟性によって、前記本体グリップ４の指掛部４ｃ，４ｃが段差部２２ｂ，２２ｂの開口寸法を広げて装着溝２２内に押し入れられ、また、前記段差部２２ｂ，２２ｂを乗り越えて装着溝２２の内側から前記指掛部４ｃ，４ｃを外側に取り出すことができるようになっている。
前記指掛部４ｃ，４ｃは前記装着溝２２の長辺部の壁面と前記段差部２２ｂ，２２ｂによって横方向（開放部２１ｂ，２２ａ，２３ｂの開口方向）への位置決めがなされる。
【００４０】
この実施の形態の補助グリップによれば、容器兼用注射器１の本体グリップ４に対し補助グリップ２０を横方向からワンタッチで着脱できると共に、本体グリップ４指掛部４ｃの方向に関係なく、常に補助グリップ２０の広い面積の指掛部（フランジ部材２１）に指を掛けて注射ができて、したがって、注射時の指保持性が確保され、注射針の刃面と本体グリップ４の指掛部４ｃとの位置合わせ作業が不要となり、注射を円滑、能率よく行うことができる。
しかも、形状が単純であり、厚さ寸法も小さくされて包装がコンパクトな形態となるので、製作、取扱が容易である。
【００４１】
次に、容器兼用注射器１に装着して使用する第３の実施の形態に係る容器兼用注射器の補助グリップ３０について図１０〜１３を参照して説明する。
前記補助グリップ３０は、合成樹脂材料で作製され、図１０に示すように、外形が円形状をした平板からなるフランジ部材３１と、該フランジ部材３１の後面に一体に結合されて、外形が前記フランジ部材３１より小さく形成されたＵ字形状の装着部材３２とを備えている。該装着部材３２の内側には、前記容器兼用注射器１の本体グリップ４のフランジ４ｂ（指掛部４ｃ，４ｃ）が挿入、嵌合される装着溝３３が、装着部材３２の外形と相似形のＵ字形状に形成して設けられている。
【００４２】
前記装着溝３３は、Ｕ字の円弧部３３ａに相当する部分の環状溝の直径が前記本体グリップ４の指掛部４ｃ，４ｃの長さ寸法（正確には、本体グリップ４の円筒状部４ａの中心を通る対角線上にある指掛部４ｃ，４ｃの角部間の距離Ｌ（図６参照））より僅かに大きくされ、Ｕ字の開口部に相当する部分が前記円弧部（環状溝）３３ａの直径と同一の間隔を有する開放部３３ｂとなっている。また、前記装着溝２２の溝幅は、全体に平行であって、前記本体グリップ４のフランジ４ｂの厚さより僅かに大きく設定されている。
【００４３】
また、前記フランジ部材３１と装着部材３２の中心部には、装着穴３１ａと貫通穴３２ａとが設けられている。前記装着穴３１ａの直径は、前記本体グリップ４の円筒状部４ａの外径より僅かに大きくされ、また、前記貫通穴３２ａの直径は、容器兼用注射器１のプランジャーロッド５の外径より大きく、前記本体グリップ４の指掛部４ｃ，４ｃの長さ寸法より小さく形成されている。
前記フランジ部材３１と装着部材３３とには、前記装着穴３１ａと貫通穴３２ａとを側方に開口する開放部３１ｂ，３２ｂが、それらの開口方向をフランジ部材３１の周方向において、前記装着溝３３の開放部３３ｂの位置と一致させてそれぞれ設けられている。フランジ部材３１の開放部３１ｂはその開口寸法が前記装着穴３１ａの直径と同一とされ、装着部材３２の開放部３２ｂはその開口寸法が前記貫通穴３２ａの直径と同一とされており、前記容器兼用注射器１の本体グリップ４の円筒状部４ａとプランジャーロッド５を側方から装着穴３１ａと貫通穴３３ａに挿入できるようになっている。
【００４４】
前記フランジ部材３１の前面には、前記装着穴３１ａと同心にして円筒部材３４が一体に接合して設けられている。該円筒部材３４は、内径が前記本体グリップ４の円筒状部４ａの直径と同一とされ、前記フランジ部材３１の周方向における開放部３１ｂの位置と一致する側方位置に、開口寸法を前記円筒状部４ａの直径より所定寸法だけ小さくした開放部３４ａが設けられている。また、前記円筒部材３４には、フランジ部材３１との接合部において、前記開放部３４ａ側から円筒部材３４を横断する方向のスリット３５，３５が開放部３４ａの両側に形成されている。各スリット３５，３５の閉鎖端部は円筒部材３４の中心位置より所定距離だけ開放部３４ａの反対側へ寄った位置まで達している。
【００４５】
前記円筒部材３４の開放部３４ａ側の前記スリット３５，３５に対応する部分は、補助グリップ３０を本体グリップ４に装着後にそこから不用意に離脱するのを防止する係止部を構成し、その内径を、本体グリップ４の円筒状部４ａの直径と同じ大きさにせずに、図１２に示すように、円筒部材４ａの直径より僅かに小さくすると、円筒部材３４は、スリット３５にもとづく開放部３４ａ側の柔軟性によって、補助グリップ３０を本体グリップ４に横から嵌め込んだとき、前記円筒状部４ａを抱き込むように押さえるので、補助グリップを本体グリップに対し軽い力で回すことができるが、自由に回らないようにすることができる。

この実施の形態の補助グリップ３０においても、前記実施の形態の補助グリップ２０と同様に、容器兼用注射器１の本体グリップ４に対し補助グリップ３０を横方向からワンタッチで着脱できると共に、本体グリップ４指掛部４ｃの方向に関係なく、常に補助グリップ２０の広い面積の指掛部（フランジ部材２１）に指を掛けて注射ができて、したがって、注射時の指保持性が確保され、注射針の刃面と本体グリップ４の指掛部４ｃとの位置合わせ作業が不要となり、注射を円滑、能率よく行うことができる。
しかも、円筒部材３４を本体グリップの円筒状部４ａの回りに回転させることにより、容器兼用注射器１の注射針の刃面との関係でフランジ部材３１の開放部３１ｂの位置を指掛けに支障のない位置へ容易に移動調節できる。
【００４８】
次に、容器兼用注射器１に装着して使用する第４の実施の形態に係る容器兼用注射器の補助グリップ４０について図１４、１５を参照して説明する。
前記補助グリップ４０は、合成樹脂材料で作製され、図１４に示すように、外形が円形の周囲を所定間隔をあけて削り落として多角形状にし、多角形の角部に円弧状部を残した形状の平板からなるフランジ部材４１と、該フランジ部材４１の後面に一体に結合されて、前記容器兼用注射器１の本体グリップ４のフランジ４ｂ（指掛部４ｃ，４ｃ）が挿入、嵌合される装着溝４２を内側に形成した外径がフランジ部材２１と同径の円形状の装着部材４３とを備えており、全体として１つの平らな円盤状に形成されている。
【００４９】
前記装着溝４２は、前記本体グリップ４の指掛部４ｃの長さ寸法（正確には、本体グリップ４の円筒状部４ａの中心を通る対角線上にある指掛部４ｃ，４ｃの両側の角部間の距離Ｌ（図６参照））より僅かに大きくされた環状溝である円弧部４２ａと、装着部材４３の側方に開口し開口寸法が該円弧部４２ａの直径と同一にした開放部４２ｂとでＵ字状に形成されており、また、前記装着溝４２の溝幅は、全体に平行であって、前記本体グリップ４のフランジ４ｂの厚さより僅かに大きく設定されている。
【００５０】
前記フランジ部材４１と装着部材４３の中心部には、装着穴４１ａと貫通穴４３ａとが設けられている。前記装着穴４１ａの直径は、前記本体グリップ４の円筒状部４ａの外径と同一にされ、前記貫通穴４３ａの直径は、容器兼用注射器１のプランジャーロッド５の外径より大きく、前記装着溝４２の直径より小さく形成されている。
前記フランジ部材４１と装着部材４３とには、それらの周方向における位置に関し前記装着溝４２の開放部４２ｂの開口方向に一致させて、前記装着穴４１ａと貫通穴４３ａとを側方に開口する開放部４１ｂ，４３ｂがそれぞれ設けられている。
【００５１】
前記フランジ部材４１の開放部４１ｂは、その開口寸法が、外側（入口側）において前記装着穴４１ａの寸法より僅かに大きくされ、内側位置（装着穴４１ｂの中心より所定距離だけ外側に寄った位置）において、フランジ部材４１に開放部４１ｂの両側から対向して突出させて設けた突起４４，４４によって、前記装着穴４１ａの寸法より所定寸法だけ小さくするように形成され、前記突起４４の内外の両側には傾斜面４４ａ，４４ｂが設けられている。
前記突起４４，４４は、補助グリップ４０を本体グリップ４に装着後にそこから不用意に離脱するのを防止する係止部を構成している。
【００５２】
また、前記開放部４１ｂの両側（両背部側）には、前記装着穴４１ａの直径方向の両側位置から該直径方向に切り込まれた後、開放部４３ｂの開口面に沿って外側に向けて延長されたスリット４５，４５がフランジ部材４１に形成されている。
また、装着部材４３の開放部４３ｂはその開口寸法が前記貫通穴４３ａの直径と同一とされており、前記容器兼用注射器１の本体グリップ４の円筒状部４ａとプランジャーロッド５を側方から前記開放部４１ｂ，４３ｂを通して装着穴４１ａと貫通穴４３ａに挿入できるようになっている。
【００５３】
この実施の形態に係る補助グリップ４０によれば、前記スリット４５，４５を設けることによって前記突起（係止部）４４，４４に良好に弾力性が付与されるので、前記本体グリップ４に補助グリップ４０を着脱する際に、補助グリップ４０に、小さな力を加えるだけで、前記本体グリップ４の円筒状部４ａが前記突起４４，４４の相互間の開口寸法を広げて装着穴４１ａ内に押し入れられ、また、前記突起４４，４４を乗り越えて装着穴４１ａの内側から外側に取り出すことができる。したがって、前記実施の形態の補助グリップ１０，２０，３０と同様に注射時の指保持性が確保され、注射針の刃面と本体グリップ４の指掛部４ｃとの位置合わせ作業が不要となり、注射を円滑、能率よく行うことができるのは勿論のこと、補助グリップ４０の本体グリップ４への着脱が容易に行え、形状も単純であり、包装がコンパクトにでき、取扱も円滑にできる。
【００５４】
なお、前記第１〜第４の実施の形態に係る容器兼用注射器の補助グリップ１０，２０，３０，４０においては、フランジ部材１１，２１，３１の外形形状を円形にして形状における方向性をなくした全方位形状に形成してたので、指掛けを行う部分が滑らかであり、使用者が楽に指を掛けることができて機能上好ましいが、フランジ部材の全方向性形状は、円形に限定されることはなく、円形もしくはそれに近い楕円に内接する角部を鈍角にした多角形によって、または、円形もしくはそれに近い楕円の周囲の複数個所を削り落として円弧部を一部残した多角形状によって構成してもよい。このように多角形もしくは多角形状にすると、注射のため補助グリップ１０，２０，３０を本体グリップ４に装着して準備された容器兼用注射器１を一時的にテーブルや医療用具台に置いたときに、該容器兼用注射器１が不安定となって転がるのを防止することができる。
