摘要： A medication injector apparatus such as an injection pen. The injection pen includes a resettable, cartridge plunger drive assembly including an axially floating nut, a cartridge plunger engaging screw, and a drive clutch movable with the nut and which when rotated causes the screw to screw through the nut. When a cartridge assembly is mounted to the pen base, the floating nut and drive clutch are shifted proximally such that the drive clutch is in torque transmitting engagement with a rotatable drive member of the pen, such that rotation of that drive member results in drive screw advancement through the nut in the distal direction. When the cartridge assembly is not mounted to the pen base, the floating nut and drive clutch are biased distally to disengage the drive clutch from torque transmitting engagement with the rotatable drive member and to thereby allow the drive screw to be reset proximally through the nut to a position more retracted within the pen base. The injection pen also may include an injection clicker assembly having a collar arranged coaxially on a drive sleeve and which oscillates axially on the drive sleeve that rotates during medication dispensing to provide an audible clicking sound that indicates injecting use of the pen. The injection pen also may include a doseable quantity identifier that uses a rotational matrix and a sensor for electrically sensing the arrangement of the dose setting mechanism of the pen, which identifier may be part of a therapeutic dose indicating system that utilizes a cartridge recognizer to recognize a concentration of medication so as to allow an automatic determination of a therapeutic dose. The injection pen further may include an assembly for selectively rotating a drive sleeve of the pen, which assembly has a dial that rotates out during dose setting and which translates in without rotation during dose injecting.
摘要翻译：药剂注射器装置，例如注射笔。注射笔包括可重置的柱塞驱动组件，其包括轴向浮动的螺母，柱塞接合螺钉和可与螺母一起移动的驱动离合器，并且当旋转时，螺杆通过螺母旋紧。当墨盒组件安装到笔底座时，浮动螺母和驱动离合器向近侧移动，使得驱动离合器与笔的可旋转驱动构件扭转传递接合，使得该驱动构件的旋转导致驱动螺钉通过螺母在远端方向前进。当墨盒组件没有安装到笔底座上时，浮动螺母和驱动离合器被向远侧偏压以使驱动离合器与可旋转驱动构件的扭矩传递接合脱离，从而允许驱动螺钉通过螺母向近侧复位到在笔底座内更缩进的位置。注射笔还可以包括具有同轴地布置在驱动套筒上并在驱动套筒上轴向振动的注射打印机组件，其在药物分配期间旋转以提供指示注射使用笔的可听到的咔嗒声。注射笔还可以包括使用旋转矩阵和用于电感测笔的剂量设定机构的布置的传感器的剂量量标识符，该标识符可以是利用盒识别器识别的治疗剂量指示系统的一部分药物浓度以允许治疗剂量的自动测定。注射笔还可以包括用于选择性地旋转笔的驱动套筒的组件，该组件具有在剂量设定期间旋转并且在剂量注射期间不转动的转盘。
