Claims (5)
- 安全ペンニードルアセンブリであって、
医療用注射器に取り付けるための機構を持つハブと、
ニードルキャリアと、
該ニードルキャリアに固定されたニードルであって、基端および末端を含み、該末端が患者への挿入用に形成されている、ニードルと、
シールドと、
該シールドが前記ニードルキャリアと協調して移動するように該シールドを前記ニードルキャリアに固定するための第1の係合可能な係止手段と
を備えており、
前記シールドが固定されている前記ニードルキャリアは、ばねが付勢する力なしで前記ハブと相対的に末端移動するように構成されており、
初期状態において、前記シールドは前記ニードルキャリアに相対的に移動可能であり、
前記ハブと相対的な前記シールドの末端移動の所定範囲において、前記第1の係合可能な係止手段が係合されて、そのために、前記シールドが前記ニードルキャリアに固定されるようになり、
前記末端移動の所定範囲を超える、前記ハブと相対的な前記シールドのさらなる末端移動のとたんに、前記シールドおよび前記ニードルキャリアが協調して一緒に前記ハブに相対的に移動して、前記ニードルの前記基端を前記ハブに相対的に末端へ移動させて退避状態にし、
前記シールドは、該シールドが前記ニードルキャリアに固定された状態で前記ニードルの前記末端を覆い、
前記ニードルキャリアを前記ハブに固定するための第2の係合可能な係止手段をさらに備え、該第2の係合可能な係止手段は、前記ニードルキャリアの前記ハブとの相対的な末端移動の二次の所定範囲において係合され、
前記ハブに前記ニードルキャリアを固定するように前記第2の係合可能な係止手段が係合された状態で、前記ニードルの前記基端は前記退避状態にあり、および、
前記シールドは、前記ニードルキャリアが前記ハブと相対的な末端移動の前記二次の所定範囲を移動している状態で、前記ニードルキャリアに固定される、
安全ペンニードルアセンブリ。 - 前記ニードルキャリアは、さらに、前記ニードルキャリアに対する前記シールドの軸方向移動を解放可能に防止することによって注射前の前記シールドの不慮の作動を制限するための構造を備えており、該構造は、前記ニードルキャリアに対する前記シールドの回転運動が前記ニードルキャリアに対する前記シールドの軸方向移動を可能にするように構成されている、請求項1に記載の安全ペンニードルアセンブリ。
- 前記ニードルキャリアと前記シールドの一方が、さらに、
軸方向チャネルであって、該チャネルの中を前記第1の係合可能な係止手段の部分が進む、軸方向チャネルと、
前記軸方向チャネルを横断して配置されるストレージチャネルと
を備え、
前記シールドは、前記第1の係合可能な係止手段の前記部分を前記ストレージチャネル内に設置して注射前の不慮の作動を制限するように、前記ニードルキャリアに対し相対的に回転可能である、請求項1に記載の安全ペンニードルアセンブリ。 - 前記ニードルキャリアと前記ハブの一方がアライメント溝を備え、前記ニードルキャリアと前記ハブの他方がアライメント歯を備え、前記ニードルキャリアと前記ハブの間の回転運動を制限しながらも、前記ハブがそれらの間の縦方向の相対移動を許容する、請求項1に記載の安全ペンニードルアセンブリ。
- 前記シールドは前記ニードルキャリアに対し軸方向に付勢されない、請求項1に記載の安全ペンニードルアセンブリ。
