摘要：
An assembly for a drug delivery device (1) is provided, comprising a housing (2), a rotation member (17) adapted and arranged to be rotated in a first and in a second rotational direction with respect to the housing (2) in an operational mode of the assembly, a drive member (16) which is configured to mechanically cooperate with the rotation member (17) such that the drive member (16) follows rotation of the rotation member (17) when the rotation member (17) is rotated in the second rotational direction and such that the rotation member (17) rotates with respect to the drive member (16) when the rotation member (17) is rotated in the first rotational direction, and a piston rod (12). The assembly further comprises at least one biasing member (27) which is adapted and arranged to provide a force tending to bring the rotation member (17) and the drive member (16) out of mechanical cooperation in the operational mode. The assembly is switchable from the operational mode into a reset mode. For switching from the operational mode into the reset mode, the biasing member (27) is configured to drive a relative axial movement between the drive member (16) and the rotation member (17) such that the rotation member (17) and the drive member (16) are brought out of mechanical cooperation. Furthermore, a drug delivery device (1) is provided.提供一種用於藥物輸送裝置(1)的組件,其係包含:一殼體(2);一旋轉構件(17),其係經設計及配置成在該組件之操作模式下可在第一及第二旋轉方向對於該殼體(2)旋轉;一驅動構件(16),其係經組態成可與該旋轉構件(17)機械合作,使得當該旋轉構件(17)在第二旋轉方向旋轉時,該驅動構件(16)跟隨該旋轉構件(17)的旋轉,以及使得當該旋轉構件(17)在第一旋轉方向旋轉時,該旋轉構件(17)相對於該驅動構件(16)旋轉;以及一活塞桿(12)。該組件更包含至少一偏壓構件(27),該至少一偏壓構件(27)經設計及配置成在操作模式下可提供傾向使該旋轉構件(17)與該驅動構件(16)不再機械合作的力。該組件可從該操作模式切換成重置模式。為了從該操作模式切換成該重置模式,該偏壓構件(27)經組態成可驅動該驅動構件(16)與該旋轉構件(17)的相對軸向運動使得該旋轉構件(17)與該驅動構件(16)不再機械合作。此外,提供一種藥物輸送裝置(1)。1...藥物輸送裝置2...殼體3...藥筒支架4...藥筒5...塞子6...劑量按鈕7...遠端8...近端9...帽蓋10...針組件11...出口12...活塞桿13...螺紋14...軸承構件15...止動構件16...驅動構件17...旋轉構件18...劑量構件20...數字套筒20A...螺紋21...小孔22...螺紋23...緊固構件24...重置構件25...彈性重置構件26...彈性操作構件27...偏壓構件28...近端止動元件30
