PROBLEM TO BE SOLVED: To provide a male luer connector preventing the proliferation of bacteria and preventing the wasteful consumption of liquid medicine.SOLUTION: This male luer connector A comprises a male luer connector body 10 including a basal end connecting portion 12 and a tip end supporting portion 13 rotatable relative to the basal end connecting portion 12 a male luer part 25 formed into a tapered shape rotatably provided within the tip end supporting portion 13 in which the outer peripheral surface of the tip end portion is decreased from the rear side to the front side and a stick-like male luer occluding portion 30 provided within the male luer part 25 which can liquid tightly occlude the tip end opening 29a of the male luer part 25. Also, an internal thread portion 15 is provided on the inner peripheral surface of the basal end connecting portion 12 and an external thread portion 31 helically engaged with the internal thread portion 15 is provided to the rear end portion of the male luer occluding portion 30, whereby the tip end opening 29a can be opened or closed by rotating the tip end supporting portion 13 relative to the basal end connecting portion 12.COPYRIGHT: (C)2008,JPO&INPIT【課題】 菌の繁殖を防止でき、かつ薬液を無駄に消費することを防止できる雄ルアーコネクターを提供すること。【解決手段】 雄ルアーコネクターAを、基端連結部12と基端連結部12に対して回転可能な先端支持部13とからなる雄ルアーコネクター本体10と、先端支持部13の内部に移動可能に設けられ先端側部分の外周面が後部側から先端側に向かって徐々に細くなるテーパ状に形成された雄ルアー部25と、雄ルアー部25内に設けられ先端部で雄ルアー部25の先端開口29aを液密的に閉塞できる棒状の雄ルアー閉塞部30とで構成した。そして、基端連結部12の内周面に内ねじ部15を設けるとともに、雄ルアー閉塞部30の後端部に内ねじ部15に螺合する外ねじ部31aを設けて、基端連結部12に対して先端支持部13を回転させることにより先端開口29aを開閉できるようにした。【選択図】 図3
