Claims (5)
- 使用前に穿刺針を覆うキャップが引抜可能に装着されていると共に、使用後に該穿刺針を側方から覆うプロテクタが傾動可能に設けられているプロテクタ付穿刺針であって、
使用前に前記キャップへ接近した傾動位置に保持された前記プロテクタに対して該キャップの引抜きに際して当接する当接突部が、該キャップに設けられており、
該キャップの引抜きに伴って該当接突部が該プロテクタへ当接して引抜力を及ぼすことで、該プロテクタが前記穿刺針から離れた傾動位置へ傾動されるようになっていると共に、
該プロテクタには、使用後に前記穿刺針を側方から収容して覆う収容溝が設けられており、該収容溝の少なくとも一方の側壁の内面に位置して、前記キャップの引抜きに伴って前記当接突部が当接する係合突部が設けられており、
使用前に前記キャップへ接近した傾動位置に保持された該プロテクタの該収容溝の両側壁の間に該キャップが入り込んで位置しているプロテクタ付穿刺針。 - 前記プロテクタが前記穿刺針から離れた前記傾動位置が安定位置とされた弾性ヒンジによって、該プロテクタが該穿刺針の針ハブに対して連結されている請求項1に記載のプロテクタ付穿刺針。
- 前記プロテクタの前記係合突部が前記収容溝の開口側に位置している請求項1又は2に記載のプロテクタ付穿刺針。
- 前記プロテクタの前記係合突部が前記収容溝の底部から離れて設けられている請求項1又は2に記載のプロテクタ付穿刺針。
- 使用前に前記キャップへ接近した傾動位置に保持された前記プロテクタにおいて、前記係合突部の基端側端面が前記収容溝の開口側から底部側に向かって前記キャップの引抜方向に傾斜している請求項1~4の何れか1項に記載のプロテクタ付穿刺針。
