    • An injection pen apparatus (30) for medicament injection including a medicament cartridge assembly (31) formed to receive and contain a medicament therein. A holding sleeve (34) is provided which is dimensioned to receive the medicament cartridge assembly (31) therein which mates with a solution transfer device (35) including an axially movable displacement rod (36). The injection pen apparatus (30) further includes a coupling mechanism (37) removably coupling the solution transfer device (35) to both a plunger (32) slidably movable in the cartridge (33) and to the holding sleeve (34). A sleeve mounting assembly (40) of the coupling mechanism (37) removably mounts the coupling mechanism to the holding sleeve (34). A locking device (41) is included which is formed and dimensioned to require joining of the displacement rod (36) relative the sleeve mounting assembly (40) after uncoupling of the rod from the plunger (32) and before uncoupling of a remainder of the solution transfer device (35) from the holding sleeve (34).
    • 一种用于药物注射的注射笔装置(30),包括形成为在其中容纳和容纳药物的药剂盒组件(31)。 设有保持套筒(34),其尺寸适于容纳其中与包括可轴向移动的移动杆(36)的溶液转移装置(35)配合的药剂盒组件(31)。 注射笔装置(30)还包括将溶液转移装置(35)可拆卸地连接到在盒(33)中可滑动地移动的柱塞(32)和保持套筒(34)的联接机构(37)。 联接机构(37)的套筒安装组件(40)将联接机构可拆卸地安装到保持套筒(34)上。 包括锁定装置(41),该锁定装置(41)形成并确定尺寸,以在杆与柱塞(32)脱离之后并且在将剩余部分(36)解耦之前需要相对于套筒安装组件(40) 溶液转移装置(35)。
