用于液体药物制剂、具体是用于胰岛素的自动施加器
摘要：
一种用于液体药物制剂的自动施加器，该自动施加器具体是用于胰岛素，更具体地用于来自可更换容器的药物的设定剂量的多次注射施加，该自动施加器包括主体壳体(1)，该主体壳体连接到具有药物，尤其是胰岛素的可更换容器的壳体(2)，该自动施加器具有适于排出药物的柱塞(12)，所述柱塞(12)通过一体驱动单元仅直线移位，该驱动单元适于固定、驱动、直线引导和锁紧所述柱塞(12)的旋转，经由双动作离合器通过位于主体壳体(1)中的拉簧(15)驱动，所述拉簧(15)经由相同的双动作离合器单元通过旋转手动剂量设定环(3)拉伸，其中所述驱动单元通过触发单元(13)启动，并且通过指示装置指示剂量，根据本发明所述自动施加器的特征在于其包括置于棘轮筒(5)的上部中的至少一个锁紧键(5.6)，该至少一个锁紧键与置于柱形主体壳体(1)的内部中的至少一个键(1.3)协作。
摘要（英）：

Automatic applicator for liquid pharmaceutical preparations comprising a body housing, having a plunger, suitable for expelling the medicine, linearly displaced by means of a driving unit, driven via a double action clutch unit, by a tensioning spring situated in the body housing, wherein the tensioning spring is a twisted spring, the said tensioning spring tensioned by a rotary hand-dose-setting ring via the same double action clutch unit, wherein the said driving unit is activated by pressing a trigger unit and a dose is indicated by an indicating arrangement via an inspection window, according to the present invention is characterised in that the double action clutch unit comprises a coupling sleeve (6) that is rigidly connected to the rotary hand-dose-setting ring (3) and radially coupled with a body of a ratchet barrel (5) that is rigidly connected to the tensioning spring (15) that is connected to a spring block (4) that is rigidly connected to the body housing (1) and secured against rotation.
