Abstract
Description
有利に、ハウジングは、閉鎖要素が第2の位置から離れるのを防ぐ止め具を有し得る。この止め具は、とりわけ、遠位開口部の横方向に、安全装置のハウジングの底部に配置することができる。止め具は、閉鎖要素が開口部の前の第2の位置に到達すると、閉鎖要素がこの位置から離れることを防ぐ。
安全装置は実質的な摩擦抵抗なしに針の軸上を摺動することができるため、好ましい実施例では、基部と安全装置との間の取外し可能な接続、とりわけスナップオン接続が設けられ得る。したがって、針の軸上の安全装置の初期の摺動を回避することができる。接続は、針を取出す際の操作中に何らかの問題を引き起こさないように、容易に取外し可能であることが好ましい。
針の先端14は、安全装置の第2の位置においてハウジング21,22に安全に囲まれる。アーム34の非弾性的変形のために閉鎖装置30を初期位置に戻すことはできないため、過失による装置の開放と針の先端が出ることとが不可能となる。湾曲した針セクション16がスリーブ33を通って摺動することができず、その結果スリーブ33はその拡大された下方頸部36のためにハウジング蓋21の近位開口部23から摺動することができないため、安全装置20は、針10から遠位方向に摺動することもできない。
Claims (10)
- 針(10)であって、
遠位端(11)と、近位端(12)と、その間に延在する軸(13)と、その遠位端(11)に先端(14)とを備え、
針の先端(14)による負傷から保護するための安全装置(20)が設けられ、
安全装置(20)は、軸(13)の近位領域(12)における第1の位置と軸(13)の遠位端(11)における第2の位置との間で軸(13)上を摺動することができるように配置され、さらに、
針の軸(13)が通過するための近位開口部(23)および遠位開口部(24)を有する閉鎖されたハウジング(21,22)を備え、
安全装置(20)が第2の位置にあるとき、針の先端(14)はハウジング(21,22)内に位置し、
安全装置(20)は、針の先端(14)がハウジング(21,22)内に位置しているときにハウジング(21,22)の遠位開口部を閉鎖する閉鎖装置(30)を含み、
閉鎖装置(30)が、開口部(24)から離れた第1の位置から開口部(24)に面する第2の位置に摺動し得、かつ針の軸(13)上に摺動するように配置された作動要素(32,33)と協動する少なくとも1つの閉鎖要素(31)を含むことと、
針の軸(13)上の作動要素(32,33)のストロークを遠位方向に規定するドライバ要素(35)が針の軸(13)上に配置されることと、
安全装置(20)をその第1の位置からその第2の位置に摺動させると作動要素(32,33)がドライバ要素(35)に当接し、安全装置(20)をさらに摺動させると、作動要素(32,33)が閉鎖要素(31)をその第1の位置からその第2の位置に移動させ、したがってハウジング(21,22)の開口部(24)を閉鎖することと、を特徴とする、針。 - 針(10)の軸(13)の断面の変更がドライバ要素(35)を表わすことを特徴とする、請求項1に記載の針(10)。

- 作動要素は、ハウジングの近位開口部(23)に摺動するように配置されるスリーブ(33)を含むことを特徴とする、請求項1〜4のいずれかに記載の針(10)。
- ハウジング(21)は、針の通過領域にチャンバ(25)を有し、その寸法は、ドライバ要素(35)と針の先端(14)との間の針のセクション(16)を収容するのに好適であることを特徴とする、請求項1〜5のいずれかに記載の針(10)。
- 安全装置(20)は、1つまたは2つの閉鎖要素(31)を有することを特徴とする、請求項1〜6のいずれかに記載の針(10)。
- ハウジング(21,22)は、閉鎖要素(31)が第2の位置から離れるのを防ぐ止め具(37)を有することを特徴とする、請求項1〜7のいずれかに記載の針(10)。
- 針(10)は近位領域(12)に基部(15)を有することを特徴とする、請求項1〜8のいずれかに記載の針(10)。
