Abstract
Description
一般的な薬剤、特にワクチン等のタンパク製剤においては、医療用容器内のシリンジに充填した後、タンパク製剤の出荷判定後に包装ラインに移される。しかしながら、この製剤は、室温では保管できないため、出荷判定まで冷蔵保管庫に保管するのが一般的である。この際に、薬剤充填作業後のシリンジを包装ラインに効率良く流動させるため、また、効率良く冷蔵保管庫に収納するため、シリンジをロンド・トレイに一方向に整列させ、重ねて保管する。このロンド・トレイにシリンジを整列させるため、シリンジは保持具取り出し自動機によって垂直方向に高速で引き抜かれる。
このため、保持具に保持されているシリンジの中心軸線と、筒孔の中心軸線のずれ量が大きいと、シリンジを引き抜く際に、キャップが、貫通孔を区画する保持部の内周縁に引っ掛かる可能性がある。キャップが保持部に引っ掛かった後、シリンジを更に引き抜こうとすると、保持具がシリンジと共に上方に持ち上がってしまう可能性がある。
その後、保持具とキャップとが相対的に移動してキャップが保持部から離れて、保持具が落下すると、その振動によって、保持具に保持された他のシリンジが保持部の筒孔から抜け出るおそれがある。シリンジが保持部の筒孔から抜け出ると、充填された充填剤がシリンジの外に漏れたり、シリンジが傷付いたりするおそれがある。
シリンジは、充填された液体を排出するための排出口が形成された先端部と、先端部と反対側の基端部と、先端部と基端部とに連続する側周部と、を有し、円筒状に形成されている。装着部材は、先端部に装着され、側周部の外半径よりも大きな外半径を有する。容器本体は、下端部に底部と、底部の周囲に連続し、上方に向かって延びる周壁部と、を有する。シリンジ保持部は、周壁部の内側に係合して底部に対向すると共に、シリンジが上下方向に挿通される貫通孔を有し、シリンジを貫通孔に挿通させて保持する。また、貫通孔を形成する周面は、上端部の半径が装着部材の外半径よりも大きく、且つ、下端部の半径が上端部の半径よりも大きく形成されると共に、下端部から上方に向かうにつれて径が小さくなるテーパ部を有する。
このため、装着部材が装着され、シリンジ保持部に保持されているシリンジを貫通孔から引き抜く際に、シリンジの中心軸線と、貫通孔の中心軸線とのずれ量が大きければ、装着部材又は装着部材が装着されたシリンジの先端部はテーパ部に当接する。そして、装着部材又はシリンジの先端部は、テーパ部の傾斜に沿って上方へ摺動し、シリンジの中心軸線と貫通孔の中心軸線とのずれ量が小さくなる。したがって、装着部材又はシリンジの先端部がシリンジ保持部における貫通孔の周囲に引っ掛かることを防止することができる。このため、シリンジ保持部を持ち上げることなく、シリンジを引き抜くことができる。
まず、本実施形態におけるシリンジ収納容器1の概略構成について、図1を参照して説明する。
図1は、本実施形態におけるシリンジ収納容器1の斜視図である。
図2及び図3は、本実施形態のキャップ30が装着されたシリンジ10を示す図である。
本実施形態のシリンジ10は、図2及ぶ図3に示すように、略円筒状に形成され、先端部がキャップ30によって塞がれた状態で、筒孔に薬液などの液体が充填される。
キャップ30は、略円筒状に形成された樹脂製の部材であり、小径部31と、大径部32と、排出部挿通孔33を有している。
次に、シリンジ保持部40について、図4を参照して説明する。
図4はシリンジ保持部40を示す図である。
次に、容器本体50について、図5を参照して説明する。
図5は、図1のシリンジ収納容器1のV-V線矢視断面図である。
図5は、図1のシリンジ収納容器1のV-V線矢視断面図である。
また、シリンジ保持部40のベース板部41が容器本体50の底部51と対向している。
実験の結果を表1に示す。
このため、キャップ30が装着され、シリンジ保持部40に保持されているシリンジ10を貫通孔43から引き抜く際に、シリンジ10の中心軸線と貫通孔43の中心軸線とのずれ量が大きければ、ルアーロック部20又はキャップ30はテーパ部45に当接する。そして、ルアーロック部20又はキャップ30は、テーパ部45に当接後、テーパ部45の傾斜に沿って上方へ摺動し、シリンジ10の中心軸線と貫通孔の中心軸線とのずれ量が小さくなる。したがって、ルアーロック部20又はキャップ30がシリンジ保持部40における貫通孔43の周囲に引っ掛かることを防止することができる。このため、シリンジ保持部40を持ち上げることなく、シリンジ10を引き抜くことができる。
本実施形態では、装着部材としてキャップ30を用いた態様を説明したが、装着部材はシリンジ10の先端部に装着される他の部材であってもよい。例えば、注射針を保持する注射針保持部であってもよい。
また、保持筒部42をベース板部41の下面から下方へ突出するように形成してもよい。この場合、シリンジ10のフランジ部16は保持筒部42の上端部及びベース板部41の上面に係止される。
すなわち、この実施形態に基づいて当業者等によりなされる他の実施形態、実施例及び運用技術等は全て本発明の範疇に含まれることは勿論であることを付け加えておく。
