Assigned to Becton Dickinson and Co · Expires 2015-05-20 · 11y expired

What this patent protects

一种药物注射笔(11)包括壳体(1)和能够相对于壳体(1)转动的剂量设置旋钮(2)。制动组件(68)布置在壳体(1)中并具有棘轮部件(43)。驱动器(21)包括至少一个外部齿(57)，该至少一个外部齿(57)接合棘轮部件(43)。棘轮部件(43)与至少一个外部齿(57)之间的接合基本上防止驱动器(21)在剂量设置和剂量校正期间相对于剂量设置旋钮(2)转动，但棘轮部件(43)与至少一个外部齿(57)之间的接合允许驱动器(21)在注射期间相对于剂量设置旋钮(2)转动。借助于本实用新型的药物注射器提供了可容易定制的简单组装。
