The present invention relates to a medicament delivery device comprising, a housing (10, 114) having a proximal and a distal end, a delivery member connected to the housing； a medicament container (84) operably arranged within the housing； a drive mechanism (102, 108) capable of acting on the medicament container (84) for priming and for expelling a dose of medicament. The invention is characterised in that the device further comprises - an activator mechanism configured to interact with the drive mechanism, such that a first interaction between the activator mechanism and the drive mechanism causes the container to move towards the delivery member wherein the container is primed and such that a subsequent second interaction between the activator mechanism and the drive mechanism causes a dose of medicament to be expelled through the delivery member.本發明有關藥物輸送裝置，其包括：外殼(10、114)，具有近側端與遠側端；輸送構件，被連接至該外殼；藥物容器(84)，可操作地配置在該外殼內；驅動機件(102、108)，能夠作用在該藥物容器(84)上，用於起動注給及用於排出一劑量之藥物。本發明之特徵為該裝置另包括：啟動器機件，被建構成與該驅動機件相互作用，使得該啟動器機件及該驅動機件間之第一相互作用造成該容器移向該輸送構件，而該容器係在該輸送構件中起動注給，並使得該啟動器機件及該驅動機件間之隨後的第二相互作用造成一劑量之藥物經過該輸送構件被排出。
