Description
使用され、それによって汚染された針の偶発的な針刺しは、病院職員および自己投与を行う人々に接する他の人の両方を、血液により媒介される疾病からの感染の危険に晒す。
、ハウジングの内側に位置し、シールドを遠位方向に付勢するばねと、ロックする突起を長手方向に有し、使用の間にハウジングに相対的にシールドと同時に移動されるロッキング要素とを含む安全針アセンブリを開示する。しかしながら、米国2005 065 476 A1は、ロッキング要素は、ばねとシールドとの間に位置し、シールドと同時に移動される別個の要素として設けられるので、ロッキング突起は、ロッキング要素の長手方向の運動中に案内することができ、それによって、トラックまたはカムに対する必要性をなくすことも開示する。
この発明の主な目的は、現状技術の安全ペン針装置の欠点を改善すること、特に、わずかの構成要素で適切な機能を実行することができる安全ペン針装置を提供することである。
この発明のさらに別の局面によれば、凹部は、少なくとも1つのガイドトラックの内周と、第1の可撓性舌部の外側を向く突起を有する端部との間に構成され、前記凹部は、針シールドが注射位置から初期位置に変位させられるとき回転子への前記針シールドのロックのために、前記少なくとも1つの突起と共同作用するよう構成される。
この出願では、用語「遠位部品/端部」が使用されるとき、これは、装置の使用中に注射部位から最も遠くに位置する装置の部品/端部またはその部材の部品/端部を指す。対応して、用語「近位部品/端部」が使用されるとき、これは、装置の使用中に注射部位から最も近くに位置する装置の部品/端部またはその部材の部品/端部を指す。
− 近位端部と遠位端部とを有する概ね管状のハブ10;80を含み、前記ハブは、その遠位端部に構成され、薬物容器アセンブリに安全ペン針装置を取付けるための取付け手段14;82と、同軸で構成された針取付け部材20;88とを含み、さらに、
− 注射端28;92と非注射端35;94とを有する注射針26;90を含み、前記注射針は、前記ハブの内側に取付けられ、針取付け部材を通って延在し;さらに、
− 前記ハブ上で回転自在に構成される概ね管状の回転可能なスリーブ30;91を含み、前記回転可能なスリーブは、その外側周面に少なくとも1つのガイドトラック46;98を含み、このガイドトラック46;98には、可撓性手段58;100;10が設けられ。さらに、
− 前記回転可能なスリーブ上で摺動するように構成される概ね管状の針シールド64;112を含み、前記針シールドはその内側周面に少なくとも1つのガイド突起74,120を含み、前記少なくとも1つの突起は、回転可能なスリーブに関しての針シールドの直線運動の案内のために、および回転可能なスリーブをハブに関して回転させるために、前記少なくとも1つのガイドトラック46;98と相互に作用するよう構成され、前記少なくとも1つの突起も、装置が使用されたときに、回転可能なスリーブに前記針シールドをロックするために、または装置が使用されたときに、回転可能なスリーブに関して針シールドの直線運動を案内するために、および回転可能なスリーブをハブに関して回転させるために、および回転可能なスリーブに前記針シールドをロックするために、前記可撓性手段と相互に作用するよう構成され、さらに、
− 装置の遠位端部に向かって前記針を付勢するために前記針シールドと共同作用する弾性手段70;116を含む。
