PEN TYPE DRUG INJECTION DEVICE WITH DOSE LIMITING NUT TO PREVENT SETTING OF A DOSE HIGHER THAN THE AMOUNT OF DRUG REMAINING
摘要：
The present invention relates to a pen type drug injection device (1; 101) with drive mechanism, comprises a housing (4, 5; 104, 105), a dose dial member (6; 106), a drive member (8; 108) engaging a lead screw (9; 109), a first clutch (18; 118) rotationally coupling the drive member (8; 108) and the housing in a coupled state and allowing relative rotation between the drive member and the housing in a de-coupled state, a second clutch (19; 119) rotationally coupling the drive member and the dial member in a coupled state and allowing relative rotation between the drive member and the dial member in a de-coupled state, and a nut (11; 111) coaxially arranged between the drive and the dial member and splined or keyed to the drive as well as threadedly engaged to the dial member, such that it moves axially on the drive member during dose setting but not during dose dispensing, and such that it eventually abuts an end stop on one of the drive or dial member, thereby limiting movement of the nut and preventing setting of a dose larger than the amount of drug remaining in the cartridge.
摘要（中）：

本发明涉及一种具有驱动机构的笔式药物注射装置（1; 101），包括一个外壳（4,5; 104,105），一个剂量拨号构件（6; 106），一个驱动构件 接合导螺杆（9; 109），第一离合器（18; 118），其以耦合状态旋转地联接所述驱动构件（8; 108）和所述壳体，并允许所述驱动构件和所述壳体之间的相对旋转， 第二离合器（19; 119），其以耦合状态旋转地联接所述驱动构件和所述刻度盘构件，并且允许所述驱动构件和所述刻度盘构件之间的脱耦合状态相对旋转;以及螺母（11; 111）同轴地布置在驱动器和拨号构件之间，并且花键或键合到驱动器上，并且螺纹地接合到刻度盘构件，使得其在剂量设定期间在驱动构件上轴向移动，但在剂量分配期间不会移动，并且使得其 最终在其中一个驱动器或拨盘构件上邻接终止挡块，从而限制了其的运动 坚果并防止剂量大于药盒中剩余药物的量。
