Description
Claims (7)
- 注射筒と、前記注射筒内で可動なプランジャとを有する自動格納式注射器であって、前記注射筒は、その前部の内側にグランドを有し、前記グランドは、皮下注射針が取り付けられる針ハブ、摺動アクチベータスリーブ、および前記注射筒内へと前記針ハブを付勢する傾向があるように前記摺動アクチベータスリーブと前記針ハブとの間に配置された圧縮されたばねを着脱可能に収容し、
前記プランジャは、前記針ハブを受け入れることができる内部空洞を有するとともに1つまたは複数の空気逃し穴を有し、
前記針ハブは、前記注射筒を出入りする前記針ハブの移動を防止する戻り止め構成によって、使用前に適所に保持され、
前記戻り止め構成は、前記針ハブ内に、その内部プロファイルが正方形または長方形である1つ以上の窪み領域であって、前記1つ以上の窪み領域は、係合されたときに、前記注射筒に入るか、または、出るかを問わない前記針ハブの動きを防止するプロファイルを有する、1つ以上の窪み領域と、前記窪み領域を占める、1つまたは複数の窪みのプロファイルと相補的な正方形または長方形のラグを有し、したがって前記針ハブを適所にロックし、前記圧縮されたばねを解放から拘束する弾性爪のセットとを備え、
前記摺動アクチベータスリーブは、前記針ハブおよび前記圧縮されたばねの周りに嵌合され、
ばねは前記針ハブおよび前記摺動アクチベータスリーブと接触し、
前記プランジャの前記摺動アクチベータスリーブとの係合は、前記戻り止め構成を解放させ、前記圧縮されたばねが前記針ハブを前記プランジャ内の前記内部空洞内に押し込むことを可能にする、自動格納式注射器。 - 前記弾性爪の上側領域は、前記針ハブから外方に傾斜した傾斜面を有し、前記摺動アクチベータスリーブは、その前縁の周りで面取りされて、傾斜面を形成し、組立時には、面取りされた面は前記弾性爪の相補的に傾斜した面に可能な限り近接して配置され、
この結果、前記摺動アクチベータスリーブが注射の方向に動く前記プランジャに係合すると、それによって加えられる力は、前記弾性爪を前記針ハブから外方に押す傾向があり、これにより前記針ハブを解放し、前記圧縮されたばねが前記針ハブを前記プランジャ内に押し込むことを可能にする、請求項1に記載の注射器。 - 前記プランジャは、その液体係合端にストッパを有し、前記ストッパは、前記針ハブを前記プランジャに押し込む前記圧縮されたばねの力によって克服され得る戻り止め構成によって定位置に保持される、請求項1または2に記載の注射器。
- 前記ストッパは、部分的に球形の液体係合面を有する、請求項3に記載の注射器。
- 前記圧縮されたばねは部分的に圧縮されて取り付けられる、請求項1または2に記載の注射器。
- 前記圧縮されたバネが部分的に圧縮されて取り付けられる、請求項3に記載の注射器。
- 前記圧縮されたバネが部分的に圧縮されて取り付けられる、請求項4に記載の注射器。
