【発明の属する技術分野】
本発明は、注射器ホルダーに関するものであり、詳しくは、注射器を使用する際に当該注射器を安全に保持するための注射器ホルダーに関するものである。
【0002】
【従来の技術】
医療などに使用される注射器は、その取扱を容易にし且つ使用中の安全性を高めるため、注射器ホルダーに収容して使用される場合がある。斯かる注射器ホルダーとしては、管状に形成され且つ注射器のシリンジ本体を収容するホルダー本体と、当該ホルダー本体の後端外周側に張出され且つ指掛部を受止める鍔と、前記ホルダー本体の先端内周部に形成され且つ注射針の基部を螺着するねじ構造のルアーロックとから主に構成された「注射器用ホルダー」が知られている(例えば、特許文献1参照。)。
【0003】
上記の注射器ホルダーは、これを使用する場合、注射器のシリンジ本体の外径よりも大径のホルダー本体を支持し、かつ、注射器の本来の指掛部よりも大きな鍔を指に掛けて操作するため、長さが短く且つ小径で手に馴染み難い小型の注射器を容易に取り扱うことが出来、眼科治療における精密な治療行為などに適している。また、先端のルアーロックにより注射針を固定するため、特に高粘度の薬剤を使用する場合でも、注射針の脱落を防止できる。更に、注射器全体を収容するため、特にガラス製注射器の使用中の破損に対しても安全である。
【0004】
【特許文献1】

【0005】
【発明が解決しようとする課題】
ところで、上記の様な注射器ホルダーは、注射器を収容するにあたり、管状のホルダー本体に後端側からシリンジ本体を挿入し、次いで、鍔に指掛部をあてがって蓋(固定部材)で締付けて固定しなければならず、しかも、ホルダー本体にシリンジ本体を固定した後に注射針を装着しなければならないため、操作手順が煩雑であり、注射の準備に手間を要すると言う問題がある。もっとも、上記の様な注射器ホルダーは、予め注射器をセットした状態で注射器と共に流通させることも出来るが、その場合には、収容した注射器の用途に限られると言う問題がある。
【0006】
本発明は、上記の実情に鑑みなされたものであり、その目的は、注射器を使用する際に当該注射器を安全に保持するための注射器ホルダーであって、極めて簡単に注射器を着脱できる様に改良された注射器ホルダーを提供することにある。
【0007】
【課題を解決するための手段】
本発明においては、注射器の着脱を容易にするため、注射器の円筒部と指掛部を上面側から圧入し得る半割り円筒状の構造を採用し、注射ノズルに装着した注射針の脱落を防止するため、注射針係止手段を有する針係止部を先端部に設けた。
【0008】
すなわち、本発明の要旨は、シリンジ本体(41)の先端に注射針(44)装着用の注射ノズル(43)が設けられ且つ後端にフランジ状の指掛部(42)が設けられ、しかも、高粘弾性の薬剤が充填された注射器(4)を収容するための注射器ホルダーであって、円筒を軸線に沿って略半割りにした形状を備え且つ注射器(4)のシリンジ本体(41)が嵌合する樋状のホルダー本体(1)と、当該ホルダー本体の後端に設けられ且つ注射器(4)の指掛部(42)が嵌合する隙間構造の鍔部(2)と、ホルダー本体(1)の先端に設けられ且つ注射器(4)の注射ノズル(43)が非接触状態で中心に位置する針係止部(3)とから成り、ホルダー本体(1)の先端側および後端側には、各々、シリンジ本体(41)の外周部を把持する一対の掛止部(11)及び(12)が設けられ、これら掛止部(11)及び(12)は、ホルダー本体(1)の軸線に直交する断面が半円よりも大きな円弧の略半円弧状に形成されて当該ホルダー本体の上縁から立ち上げられた部位であり、鍔部(2)は、上面側が指掛部の直径よりも大きな幅に亙って開放された隙間(21)を有し、針係止部(3)は、ホルダー本体(1)の軸線に直交する内周部断面が略半円弧状に形成され且つその内周部に注射針(44)の基部を係止する注射針係止手段としてのねじ状の突条(31)が設けられ、当該突条は、注射針(44)のカプラー(44c)の基端部に張出された一対の張出片が係合するようになされていることにより、シリンジ本体(41)及び指掛部(42)を上面側から圧入し、注射ノズル(43)に装着した注射針(44)を係止する様になされていることを特徴とする注射器ホルダーに存する。
【0009】
【発明の実施の形態】
本発明に係る注射器ホルダーの一実施形態を図面に基づいて説明する。図1〜図11は、本発明に係る注射器ホルダーを示す図であり、各々、図1は正面図、図2は背面図、図3は平面図、図4は底面図、図5は右側面図、図6は左側面図である。また、図7は図3におけるA−A線に沿って破断した断面図、図8は図3におけるA−A線に沿って破断した拡大断面図であり、図9は図3におけるB−B線に沿って破断した断面図、図10は図3におけるB−B線に沿って破断した拡大断面図であり、図11は拡大正面図である。更に、図12は本発明に係る注射器ホルダーの使用状態を示す参考図である。
【0010】
本発明の注射器ホルダーは、注射器をより安全に使用するために当該注射器を収容するためのホルダーである。本発明の注射器ホルダーは、複数の部材を組み合わせて構成されてもよいが、通常は合成樹脂の一体成形により構成される。注射器ホルダーを構成する樹脂としては、ポリプロピレン、ポリエチレン、ポリエチレンテレフタレート等の各種の熱可塑性樹脂が挙げられる。また、注射器ホルダーは、注射器や薬剤に対する視認性を高めるため、透明性の樹脂によって構成されてもよい。
【0011】
本発明の注射器ホルダーを適用する注射器は、一般的な構造の注射器であり、図12に符号(4)にて示す様に、円筒状のシリンジ本体(41)の先端に注射ノズル(43)が設けられ且つ後端にフランジ状の指掛部(42)が設けられており、注射ノズル(43)には注射針(44)が装着され、シリンジ本体(41)内には薬剤押出用のプランジャ(図示省略)が挿入され、当該プランジャにはこれを押送するためのプランジャロッド(45)が取り付けられる様になされている。なお、上記の注射器(4)は、後述するヒアルロン酸などの薬剤が予め充填された薬剤既充填型の注射器であってもよく、また、シリンジ本体(41)は、ガラス製であってもよい。
【0012】
本発明の注射器ホルダーは、図12に示す様に、注射器(4)のシリンジ本体(41)の円筒部が嵌合する樋状のホルダー本体(1)と、当該ホルダー本体の後端に設けられ且つ注射器(4)の指掛部(42)が嵌合する隙間構造の鍔部(2)と、ホルダー本体(1)の先端に設けられ且つ注射器(4)の注射ノズル(43)が非接触状態で中心に位置する針係止部(3)とから主として構成される。
【0013】
ホルダー本体(1)は、図1〜図6に示す様に、円筒を軸線に沿って略半割りにした形状を備えている。ホルダー本体(1)の内径および長さは、注射器(4)のシリンジ本体(41)の規格に応じてシリンジ本体(41)が略緩みなく嵌合する大きさに設計される。そして、図1、図3〜図8及び図11に示す様に、ホルダー本体(1)の少なくとも一部は、軸線に直交する断面が半円よりも大きな円弧の略半円弧状に形成される。
【0014】
具体的には、ホルダー本体(1)の先端側および後端側には、各々、一対の掛止部(11)及び(12)が設けられる。これら掛止部(11)及び(12)は、ホルダー本体(1)の上縁から幾分立ち上げられた部位であり、掛止部(11)及び(12)が設けられた部位においては、軸線に直交する断面がホルダー本体(1)の他の部位よりも大きな円弧に形成されている。すなわち、掛止部(11)及び(12)は、ホルダー本体(1)にシリンジ本体(41)を収容した場合、シリンジ本体(41)の外周部を把持する機能を発揮する。
【0015】
鍔部(2)は、図12に示す様に、注射器(4)の指掛部(42)を収容する部位である。鍔部(2)は、図1〜図11に示す様に、指掛としての耳(23)が左右に張出された半リング状の平板体を前後に隙間を開けて配置し且つこれらの外周部の一部を連結片(22)により相互に結合した状態に構成される。すなわち、鍔部(2)は、図3〜図6に示す様に、上面側が指掛部(42)の直径よりも大きな幅に亙って解放された隙間(21)を有し、斯かる隙間(21)にシリンジ(41)の指掛部(42)を嵌合させる様になされている。鍔部(2)の隙間(21)の大きさは、指掛部(42)の略厚さに相当する大きさとされる。
【0016】
針係止部(3)は、図1、図2及び図7〜図11に示す様に、軸線に直交する内周部断面が略半円弧状に形成され、かつ、図3に示す様に、その内周部に注射針(44)の基部のカプラー(44c)を係止する注射針係止手段としてのねじ状の突条(31)が設けられる。具体的には、図12に示す様に、注射針(44)のカプラー(44c)の基端部には、一対の張出片が左右に張出されており、針係止部(3)の内周面には、図3に示す様に、前記の張出片を係合させて幾分締め込み可能な螺旋状になされた突条(31)が設けられる。すなわち、針係止部(3)は、従来の注射器用ホルダー先端のルアーロックを軸線に沿って半割りにした構造を有する。
【0017】
更に、一旦注射ノズル(43)に装着した注射針(44)が仮に緩んだ場合にも、注射針(44)の脱落をより確実に防止するため、図5、図6及び図9〜図11に示す様に、針係止部(3)の先端上面側には、注射針(44)のカプラー(44c)基端部の上記の張出片を引っ掛けるための一対の引掛り部(33)がが突設される。引掛り部(33)は、突条(31)からカプラー(44c)の張出片が外れかかった場合に当該張出片を針係止部(3)の先端側で引っ掛ける様に機能する。なお、図中の符号(32)は、針係止部(3)の成形時の変形および使用時の変形を防止するための補強用のリブを示す。
【0018】
上記の様に、本発明の注射器ホルダーは、円筒を半割りにした構造の樋状のホルダー本体(1)及び針係止部(3)、ならびに、上面側が開口した隙間構造の鍔部(2)から主として構成され、かつ、針係止部(3)の内周部に注射針係止手段を備えており、注射器(4)のシリンジ本体(41)および指掛部(42)を上面側から圧入し、注射ノズル(43)に装着した注射針(44)を係止する様になされている。
【0019】
すなわち、本発明の注射器ホルダーに注射器(4)を収容する場合には、図12に示す様に、注射針(44)を装着した注射器(4)を上方から押し付ける様にしてホルダー内に固定する。換言すれば、ホルダー本体(1)に注射器(4)のシリンジ本体(41)を嵌合させ且つ掛止部(11)及び(12)にて把持することにより、注射器(4)の上下左右方向の動きを規制し、鍔部(2)に注射器(4)の指掛部(42)を嵌合させることにより、注射器(4)の前後方向の動きを規制する。
【0020】
また、針係止部(3)の注射針係止手段に注射針(44)を係合させることにより、注射針(44)の脱落を防止する。具体的には、注射器(4)の注射ノズル(43)に装着した注射針(44)の結合が緩い場合には、注射時の液漏れを防止するため、注射針(44)を僅かに回転させ、針係止部(3)の内周部に接触する注射針(44)のカプラー(44c)基端部の張出片を突条(31)の間の溝に噛み合わせる様に突条(31)に沿って回転移動させることにより、注射針(44)を締め込み、注射ノズル(43)に対する注射針(44)のカプラー(44c)の結合力、ならびに、針係止部(3)に対する注射針(44)のカプラー(44c)の結合力を高める。
【0021】
上記の様に注射器ホルダーに収容した注射器(4)を使用する場合には、ホルダー本体(1)の基端部を指先に挟む様に且つ指先を鍔部(2)に引っ掛け、そして、プランジャロッド(45)を操作し、対象に薬液を注射する。 なお、医療現場などにおいては、通常、注射器(4)を実際に使用するまでの間、注射針(44)は、保護カバー(図示省略)を装着した状態で取り扱われる。
【0022】
上記の様に、本発明の注射器ホルダーは、従来のホルダーと同様に、注射器(4)のシリンジ本体(41)の外径よりも大径のホルダー本体(1)を指で支持し且つ注射器(4)の指掛部(42)よりも大面積の鍔を指に掛けて操作する様になされているため、これを使用することにより、小型の注射器でも容易に取り扱うことが出来る。また、注射器(4)のシリンジ本体(41)をその全長に亙って収容できるため、特にガラス製注射器の破損に対しても安全である。
【0023】
更に、本発明の注射器ホルダーは、針係止部(3)に注射針係止手段としての上記の様なねじ状の突条(31)が設けられているため、注射ノズル(43)に装着した注射針(44)を僅かに回転させて締め込むだけで、注射針(44)の結合力を確実に高めることが出来、注射針(44)の使用時の脱落や液漏れを確実に防止できる。従って、通常の薬剤が充填された注射器は勿論、例えば、関節内注射剤、眼科手術補助剤、臓器や組織の癒着防止剤などとして使用されるヒアルロン酸やその修飾体またはこれらのゲルあるいはコラーゲン、合成高分子物質と言った高粘弾性の薬剤が充填された注射器にも好適である。
【0024】
しかも、本発明の注射器ホルダーは、上記の様に、円筒を半割りにした構造のホルダー本体(1)及び針係止部(3)、ならびに、上面側が開放された隙間構造の鍔部(2)によって構成され、かつ、ホルダー本体(1)の一部の断面が半円よりも大きな円弧の略半円弧状に形成されているため、上面側から押し付けるだけで注射器(4)を収容でき且つ動かない状態に固定でき、また、上方に持ち上げるだけで注射器(4)を取り外すことができ、着脱が極めて簡単である。更には、注射針(44)やプランジャロッド(45)を装着した状態でも、これらを装着しない状態でも着脱でき、かつ、注射器(4)を直接確認しながら操作できるため、取扱が極めて容易である。
【0025】
なお、本発明において、注射針係止手段としては、ねじ状の突条(31)に限定されるものではなく、例えば、図示した引掛り部(33)を更に拡大した構造のもの、あるいは、針係止部(3)の縁部に略半円弧状の突出部を設けて注射針(44)のカプラー(44c)基端部が一層確実に引っ掛かる様にした構造のものでもよい。
【0026】
【発明の効果】
以上説明した様に、本発明の注射器ホルダーによれば、円筒を半割りにした構造のホルダー本体および針係止部、ならびに、上面側が開放された隙間構造の鍔部によって構成され、かつ、ホルダー本体の一部の断面が半円よりも大きな円弧の略半円弧状に形成されており、上面側から押し付けるだけで注射器を収容でき且つ動かない状態に固定でき、また、上方に持ち上げるだけで注射器を取り外すことができるため、着脱が極めて簡単であり、しかも、注射針やプランジャロッドを装着した状態でも、これらを装着しない状態でも着脱でき、かつ、注射器を直接確認しながら操作できるため、取扱が極めて容易である。

BACKGROUND OF THE INVENTION
The present invention relates to a syringe holder, and more particularly to a syringe holder for safely holding the syringe when the syringe is used.
[0002]
[Prior art]
A syringe used for medical treatment or the like may be used by being housed in a syringe holder in order to facilitate handling and enhance safety during use. Such a syringe holder includes a holder body that is formed in a tubular shape and accommodates the syringe body of the syringe, a collar that protrudes from the outer periphery of the rear end of the holder body and that receives the finger hook, and a tip of the holder body There is known a “syringe holder” which is mainly composed of a luer lock having a screw structure formed on an inner peripheral portion and screwed to a base portion of an injection needle (see, for example, Patent Document 1).
[0003]
When the syringe holder is used, the syringe holder supports a holder body having a diameter larger than the outer diameter of the syringe body of the syringe, and is operated by hooking a finger with a hook larger than the original finger hook portion of the syringe. Therefore, it is possible to easily handle a small-sized syringe that is short in length and small in diameter and difficult to fit in the hand, and is suitable for precise treatment in ophthalmic treatment. Further, since the injection needle is fixed by the luer lock at the tip, it is possible to prevent the injection needle from falling off even when a highly viscous drug is used. Furthermore, since the entire syringe is accommodated, it is safe against damage during use of the glass syringe in particular.
