    • PROBLEM TO BE SOLVED: To perform the exchange or supplement of an injection solution without pulling out an injection needle from a patient's body in an injection needle unit for insulin automatic injector comprising a connector to be connected to an insulin pump; and an injection needle member to be injected to the abdominal part, which is connected to the connector through a conduit. SOLUTION: The conduit 1 is dividable into two (1a and 1b) in an optional position. A first head body 100 and a second head body 200 are mounted on the end of the conduit 1a on the connector 2 side and the end of the conduit 1b on the injection needle member 3 side, respectively, and the first head body 100 is removably connected and fixed to the second head body 200 through a connecting ring 300. A cylinder-like housing part 110 is formed on the second head 200 side of the first head body 100, and a connecting needle 120 is provided in the center thereof and extended through a sealing body 210 in the state where the first head body 100 is connected to the second head body 200.
    • 要解决的问题:在胰岛素自动注射器的注射针单元中从患者身体拔出注射针而执行注射溶液的更换或补充,所述注射针单元包括要连接到胰岛素泵的连接器; 以及注射到腹部的注射针构件,其通过导管连接到连接器。 解决方案:导管1可分为两个(1a和1b),位于可选位置。 分别在连接器2侧的导管1a的端部和注射针构件3侧的导管1b的端部分别安装第一头本体100和第二头本体200,并且第一头本体100可拆卸地 通过连接环300连接并固定到第二头本体200.在第一头主体100的第二头部200侧上形成有圆筒状的壳体部110,并且在其中心设置有连接针120 在第一头本体100连接到第二头本体200的状态下通过密封体210。
