Herein a medicament delivery device (2) is disclosed. The device (2) comprises a housing (4), a container holder (22) for a medicament container (11), a first energy accumulating member (14) for powering a dispensing of a medicament from the medicament container (11), and a releasable first locking arrangement (18) for locking the first energy accumulating member (14) in a first energy storing position. The medicament delivery device (2) further comprises a second energy accumulating member (16) for powering a mixing of a medicament in the medicament container (11), and a releasable second locking arrangement (20) for locking the second energy accumulating member (16) in a second energy storing position. The second locking arrangement (20) in a first state prevents the first locking arrangement (18) from being released, and the second locking arrangement (20) in a second state permits the first locking arrangement (18) to be released.在此中，藥物輸送裝置(2)被揭示。該裝置(2)包含外殼(4)；用於藥物容器(11)的容器夾具(22)；第一蓄能構件(14)，用於對來自該藥物容器(11)之藥物的配送供給動力，及可釋放之第一鎖定配置(18)，用於將該第一蓄能構件(14)鎖定在第一能量儲存位置中。該藥物輸送裝置(2)另包含第二蓄能構件(16)，用於對藥物在該藥物容器(11)中的混合供給動力，及可釋放之第二鎖定配置(20)，用於將該第二蓄能構件(16)鎖定在第二能量儲存位置中。該第二鎖定配置(20)於第一狀態中防止該第一鎖定配置(18)被釋放，且該第二鎖定配置(20)在第二狀態中允許該第一鎖定配置(18)被釋放。
