用于药物传输装置之组件及具有该组件之药物传输装置;ASSEMBLY FOR A DRUG DELIVERY DEVICE AND DRUG DELIVERY DEVICE WITH SUCH AN ASSEMBLY

摘要

本揭示系有关一用于药物传输装置(1)之组件，其包含一壳体部份(10)，一可相对于壳体部份(10)位移之活塞杆(17)，一第一套筒构件(6)及一第二套筒构件(7)。第一及第二套筒构件(6,7)系耦合至壳体部份(10)。在组件的一初始状态中，第一套筒构件(6)可相对于第二套筒构件(7)从一初始位置移动至一第二位置，其容许活塞杆(17)从一初始位置轴向地移行至一预定第二位置，俾使组件处于一起动状态。并且，在组件的起动状态中，第一套筒构件(6)相对于第二套筒构件(7)位于第二位置中，第一及第二套筒构件(6,7)系藉由一第一接合特征(9)被永久性旋转且轴向地锁定至彼此，俾使第一及第二套筒构件(6,7)一起形成一套筒(14)。;此外，本发明描述一具有该组件之药物传输装置(1)。;The present disclosure pertains to an assembly for a drug delivery device (1) comprising a housing part (10), a piston rod (17) displaceable relative to the housing part (10), a first sleeve member (6) and a second sleeve member (7). First and second sleeve members (6, 7) are coupled to the housing part (10). In an initial state of the assembly the first sleeve member (6) is movable from an initial position to a second position relative to the second sleeve member (7) which allows the piston rod (17) to axially travel from an initial position to a predetermined second position such that the assembly is in a primed state. Moreover, in the primed state of the assembly, with the first sleeve member (6) being in the second position relative to the second sleeve member (7), first and second sleeve members (6, 7) are permanently rotationally and axially locked to each other by a first engagement feature (9) such that first and second sleeve members (6, 7) together form a sleeve (14). ;Additionally, a drug delivery device (1) with such an assembly is described.
