The present invention relates to a medicament delivery device comprising a generally elongated housing comprising a proximal part (10) and a distal part (12) a medicament cartridge (18) comprising a proximal opening closed by a septum (30), an axially movable distal stopper (26), and a first enclosure (20) wherein a liquid and a gaseous fluid are enclosed a medicament delivery member (36) attachable to said proximal part (10) and having a non-delivery end (34) a medicament cartridge holder (16) wherein the medicament cartridge is coaxially arranged, said cartridge holder being arranged coaxially movable inside said proximal part and comprising holding means (38, 40) capable of holding said medicament cartridge holder (16) in a non-activated position in which said cartridge holder is releasebly engaged to said proximal part and in which a predetermined distance is present between the septum and the non-delivery end a manual pressure mechanism arranged to be moved from a non-pressure position to a pressure position wherein a pressure is build-up inside said cartridge and an activation mechanism arranged to interact with said holding means only when said manual pressure mechanism is in the pressure position for disengaging said cartridge holder from said non-activated position to an activated position in which said cartridge holder is axially displaced said predetermined distance whereby said septum is penetrated by the non-delivery end and the liquid is expelled due to the pressure built inside the enclosure.一種藥物輸送裝置,係包括一普通瘦長外殼包括一近側部(10)和一末端部(12);一藥物容器(18)包括一近側開口被一隔膜(30)封閉;一可軸向移動的末端瓶塞(26);和一第一圍牆(20),在此液狀和氣狀的流體被封住;一藥物輸送構件(36)附於該近側部(10)且有一非輸送端(34);一藥物容器支撐件(16),在此,藥物容器被同軸地置放,藥物容器支撐件可同軸地移動於該近側內,且包括支撐裝置能夠支撐該藥物容器支撐件(16)於非啟動位置,在此該藥物容器支撐件與該近側可鬆開地嚙合,且一預設距離顯示在隔膜和非輸送端之間;一手動壓力機制可從非壓力位置移至壓力位置,在此容器內產生合成壓力;一啟動機制與該支撐裝置互動(只限於當該手動壓力機制在壓力位置時),以使該容器支撐件從該非啟動位置解除嚙合而到啟動位置,在此該容器支撐件被軸地位移該預設距離,藉此該隔膜被非輸送端穿刺,且液體因內部壓力的產生而被排出。10‧‧‧近側部11‧‧‧夾12‧‧‧末端部14‧‧‧螺紋48‧‧‧按鈕54‧‧‧窗口56‧‧‧標示裝置
