摘要：
A drive mechanism 2100, 3100 includes a housing 2130, a piston 2110 adapted to impart movement to a plunger seal 2060 within a drug container 2050, a plurality of biasing members 2106, 2122 disposed in parallel, and a retainer 2115. The biasing members 2106, 2122 are disposed to release energy to cause movement of the piston 2110 from a retracted first position to the extended second position, the piston 2110 bearing against the plunger seal 2060 to dispense medicine. The retainer 2115 is disposed to maintain the biasing members 2106, 2122 in the energized position and to release the biasing members 2106, 2122 to permit the piston 2110 to dispense the medicine. The drive mechanism 2100, 3100 may also include an end-of-dose indicator 2133, 3133 to identify at least one of when the sleeve assembly 2120, 3120 is disposed subjacent a window 2131, 3131 in the housing 2130, 3130 the relative motion of the sleeve assembly 2120, 3120 with reference to the window 2131, 3131 or another reference component, the stoppage of such motion, and the rated or change of rate of motion.
摘要（中）：
驱动机构2100,3100包括壳体2130，活塞2110，适于向药物容器2050内的柱塞密封件2060施加活动，多个平行设置的偏置构件2106,2122和保持器2115.偏置构件2106 ，2122被设置为释放能量以使活塞2110从缩回的第一位置移动到延伸的第二位置，活塞2110抵靠柱塞密封件2060以分配药物。 保持器2115设置成将偏置构件2106,22122保持在通电位置并且释放偏压构件2106,2122以允许活塞2110分配药物。 驱动机构2100,3100还可以包括剂量终止指示器2133,33133，以识别当套筒组件2120,31220设置在壳体2130内的窗口2131,33131的下方时，3130中的至少一个，3130的相对运动 套筒组件2120,31220参照窗口2131,33131或另一参考部件，停止这种运动以及运动速度的额定或改变。
