The present disclosure relates to a medicament delivery device (1) for injection of a medicament. The medicament delivery device (1) comprising a housing (3) having a distal end opening and a proximal end opening a needle guard (9) extending from the proximal end opening and moveable relative tothe housing (3) from an extended position to a retracted position in which the needle guard (9) is biased towards the extended position. The device (1) further comprises an activation member (5) extending from the distal end opening and movable relative to the housing (3) from an initial position to a final position final position locking means arranged to restrict movement of the activation member (5) relative to the housing (3) when the activation member (5) is in the final position, and needle guard locking means arranged to interact with the needle guard (9) such that movement of the needle guard (9) from the extended position to the retracted position is restricted when the activation member (5) is in the final position. The present disclosure also relates to a method of assembling a medicament delivery device (1).本揭示內容有關一藥物輸送裝置(1),用於藥物之注射。該藥物輸送裝置(1)包括外殼(3),具有一遠側端開口及一近側端開口;針防護件(9),由該近側端開口延伸,並可相對該外殼(3)由一延伸位置運動至一縮回位置,其中該針防護件(9)被偏向朝該延伸位置。該裝置(1)另包括啟動構件(5),其由該遠側端開口延伸及可相對該外殼(3)由一最初位置運動至一最後位置;最後位置鎖定機構,被配置來當該啟動構件(5)係於該最後位置中時,限制該啟動構件(5)相對該外殼(3)的運動;及針防護件鎖定機構,被配置來與該針防護件(9)互相作用,使得當該啟動構件(5)係於該最後位置中時,該針防護件(9)由該延伸位置至該縮回位置之運動被限制。本揭示內容亦有關一組合該藥物輸送裝置(1)的方法。1‧‧‧藥物輸送裝置3‧‧‧外殼5‧‧‧啟動構件7a‧‧‧蓋子7b‧‧‧注射針屏蔽件9‧‧‧針防護件11‧‧‧標籤13‧‧‧窗口
