Description
(1)先端に接続部を有し基端が開口した注射筒を含むシリンジであって、前記接続部は、形状の異なる複数の被接続部材に着脱自在に接続可能な接続手段が設けられており、前記接続手段は、前記接続部先端から基端側に設けられた第1の被接続部材に接続可能な外周面である国際標準規格で定められたオスルアーテーパーフィッティングと、前記外周面よりも基端側の接続部に設けられた第2の被接続部材に接続可能な係合部であり、
注射針と、前記注射針の基端に固着された針基と、前記注射針が挿通し前記針基を先端方向に嵌合可能かつ基端方向に離脱可能であるとともに前記係合部に接続可能な針基蓋部材とを含むセーフティ針を有することを特徴とするシリンジ。
(2)前記係合部が、前記接続部の軸心と直交する円周凸部であることを特徴とする(1)に記載のシリンジ。
(3)前記凹部が、前記接続部の軸心と直交する円周溝であることを特徴とする(1)に記載のシリンジ。
を用いることにより、接続部に、複数の接続手段を備えることによって、専用セーフティ針を一定位置に接続可能であるとともに、通常、接続部に嵌合によって接続されるオプションを用いることができるため、薬剤採取時には一般針を用い、人体穿刺時には専用セーフティ針を用いるといった使い分けが可能であることを見出し本願発明に至った。
