Claims (11)
- 本体部(10)と、
前方端でニードル(50)を有するシリンジ(12)と、
前記シリンジ(12)に対して延在する通路(16)を画成する1又は複数の壁と、を具備し、前記シリンジ(12)が、前記ニードル(50)の前方先端が前記通路によって包囲された後方の後退位置と、前記前方先端が前記通路の前記前方端から延出する前方の延出位置と、の間を通過することのできる注射装置であって、
前記通路が、前記通路の有効断面を狭めるため前記通路の前記壁から内方に突出する複数の横突出部(26、28、34)を有しており、少なくともいくつかの前記横突出部が、前記通路の前記前方端に向かって内方に傾斜する弾性的に偏向可能な部分(28)を有する注射装置。 - 前記通路の前記前方端の前記有効断面の横断寸法が、シリンジの容器の径よりも小さく、それによって少なくともいくつかの前記横突出部が係合し、前記シリンジにおいて前記シリンジが所定の前方位置を越えて前方移動するときの制動効果として機能する請求項1に記載の注射装置。
- 前記通路の前記壁が、前記本体部(10)に対して相対運動可能なニードルカバー要素(16)を具備する請求項1又は請求項2のいずれか1つに記載の注射装置。
- 前記シリンジ(12)が前記本体部に対して後方位置から前方位置へと相対運動可能な請求項1から請求項3のいずれか1つに記載の注射装置。
- 前記シリンジ(12)が、シリンジニードルを覆うと共に前記ニードルを露出させるために長手方向に引き出し可能なブート要素(52)を有し、当該注射装置が、最初に当該注射装置の前端の少なくとも一部を覆うと共に前記ブート(52)を引き出すため長手方向に取り外し可能である取り外し可能なキャップ(38)を更に有する請求項1から請求項4のいずれか1つに記載の注射装置。
- 前記ブート要素(52)が、前記通路(16)の後方端内でクリアランスを有しながら受容可能でありつつも前記通路の前記前方端の前記有効断面よりも大きいが、前記偏向可能な部分(28)の変形によって通過することができる外部最大横断寸法を有する請求項5に記載の注射装置。
- 前記キャップ(38)が、当該キャップが初期位置にあるときに前記通路を通して後方に延出して前記ブート(52)に係合する複数の指部(46)を有する請求項5又は請求項6のいずれか1つに記載の注射装置。
- 前記キャップ(38)において前記指部(46)が、前記通路の長手方向軸線周りに環状方向に前記突出部(26)と交互に並ぶ請求項7に記載の注射装置。
- 前記横突出部(26)及び前記指部(46)が、クリアランスを有しながら前記ブート要素(52)の外部表面を覆う後方の略円筒表面を共に画成する内部弓形表面をそれぞれ有する請求項8に記載の注射装置。
- 前記通路が、前記キャップが取り外されるとき前記キャップの前記複数の指部(46)の外部面に係合するための支持表面(34)を有する請求項5から請求項9のいずれか1つに記載の注射装置。
- 注射装置であって、
本体部(10)と、
前方端でニードル(50)を有するシリンジ(12)と、
前記ニードルを覆うブート(52)と、前記シリンジ(12)に対して延在する通路(16)を画成する1又は複数の壁であって、前記シリンジ(12)が、前記ニードル(50)の前方先端が前記通路によって包囲された後方の後退位置と、前記前方先端が前記通路の前記前方端から延出する前方の延出位置と、の間を通過することのできる1又は複数の壁と、
前記通路の有効断面を狭めるため前記通路の前記壁から内方に突出している複数の延在する横突出部(26、28)と、
当該注射装置の前端において初期配置されるキャップ(38)であって、当該キャップが初期位置にあるときに前記通路を通して後方に延出して前記ブート(52)に係合する複数の延在する指部(46)を有する取り外し可能な前記キャップ(38)と、を具備する注射装置において、
前記指部(46)が前記横突出部(26)に対し環状に離散されている注射装置。
