Claims (11)
- 基端と末端とそれら端部の間に延在する通路とを有する針ハブと、
基端と末端とそれらの間に延在するルーメンとを有する針カニューレであって、前記針カニューレの前記基端は前記針ハブの前記末端側の前記通路に固定されている針カニューレと、
前記針ハブから延在する弾性的に屈折可能な作動腕と、前記作動腕に形成され、前記針ハブに対して外方向に突き出た1つの作動ボタンと、
基端と末端とそれら端部の間に延在する通路とを有する胴部であって、前記針ハブは前記胴部の前記通路に、前記針ハブ、針カニューレおよび前記作動腕が、前記胴部に対して、前記針カニューレが前記胴部を超えて末端方向に突出する末端位置から、前記針カニューレが前記胴部にすっかりと納まる基部位置まで移動可能となるように配置され、前記胴部はそれを貫く1つの作動開口部を有し、前記針ハブは前記末端位置にあるとき、前記作動ボタンは前記作動開口部の中へ突き出し、前記作動開口部近傍の前記胴部の一部と係合し、前記作動ボタンは前記作動開口部と係合する上で弾性的に外側へ屈折可能となる構成の胴部と、
前記胴部に配置されたばねであって、前記作動ボタンが前記作動開口部から前記胴部の内側に反らされたとき、前記針ハブを前記基部位置に押し進めるために前記針ハブ近傍に配されるばねと、
不慮の作動を防ぐために、前記作動ボタンよりも大な半径方向の距離で、作動開口部における前記胴部の基端部と末端部の部分が突き出すように、前記胴部の断面が減少する部分に配置されている前記作動開口部と、
を具える伸縮自在の安全針。 - 前記針カニューレの前記末端はおおよそ平らなベベルを形成し、該ベベルは、前記針カニューレの中心軸を含む平面に対して、面対称に設けられており、前記作動腕は、前記針カニューレの中心軸を含む平面に対して、面対称に設けられていることを特徴とする請求項1に記載の伸縮自在の安全針。
- ベベルと作動ボタンは前記伸縮自在の安全針の同じ側に向けられていることを特徴とする請求項2に記載の伸縮自在の安全針。
- 前記作動腕は前記針ハブからカンチレバーとなっており、前記作動腕は底部を前記針ハブと一体不可分な底部端と、該底部端から末端方向に突き出た自由端を有することを特徴とする請求項1ないし3のいずれかに記載の伸縮自在の安全針。
- 前記作動腕は第一作動腕であり、伸縮自在の安全針はさらに前記胴部に置かれた第2作動腕を具え、該第2作動腕は、前記第一作動腕と係合する位置に突出し、前記第一作動腕を屈折させることを特徴とする請求項1ないし4のいずれかに記載の伸縮自在の安全針。
- さらに、前記胴部に置かれ、胴部の横断方向に突出した一対の可撓性の羽根を具え、該羽根は、前記針カニューレの中心軸を含む前記平面に対しておおよそ垂直な平面に形成され、前記第2作動腕は前記可撓性の羽根とともに一体的に形成されていることを特徴とする請求項5に記載の伸縮自在の安全針。
- 前記作動開口部は、前記胴部の前記作動開口部の基端側および末端側の部分は突起し、不慮の作動を防ぐために半径方向の距離が前記作動ボタンよりも大きくなるように、前記胴部の断面積が小さい部分に配置されることを特徴とする請求項1ないし6のいずれかに記載の伸縮自在の安全針。
- 前記胴部に配置され、少なくとも前記ばねと前記針ハブの部分を覆う制動物質を具え、該制動物質は針カニューレが収縮している間の制動な移動を行い、それによって前記針カニューレについた物質の飛び散りを減少させることを特徴とする請求項1ないし7のいずれに記載の伸縮自在の安全針。
- 前記ばねは、複数の隣接するコイルを具え、前記制動物質は前記ばねの隣接するコイルの間に一時的な弾性接合をし、前記作動ボタンが前記作動開口部から外れた後の前記針ハブの最初の加速を遅くさせることを選択することを特徴とする請求項8に記載の伸縮自在の安全針。
- 前記制動物質はチキソトロピックジェルであることを特徴とする請求項9に記載の伸縮自在の安全針。
- 前記針カニューレの保護に働くばねを制動するための制動因子としてチキソトロピックジェルは使用されることを特徴とする請求項10に記載の伸縮自在の安全針。
