The invention relates to an administration device, in particular an administration device comprising a container (1, 1d) and a mixing device for mixing an active substance with a dilution liquid in the container (1, 1d). The administration device comprises a container (1, 1d) with at least one first chamber (1e) containing the active substance and a second chamber (1f) containing the dilution liquid for the active substance, the container (1, 1d) including a seal at one end in the form of a membrane (2), and comprises a mixing device for mixing the active ingredient with the dilution liquid for the active substance. The administration device also comprises an injection needle unit (4) with a distal needle portion (4a) facing away from the container (1, 1d) for piercing the skin, and disposed opposite thereof a proximal needle portion (4b) that faces the membrane (2) when the administration device is in the initial position, and which is thrust through the membrane (2) into the container (1, 1d) in a mixing position, wherein the administration device further includes a protective sleeve (5) which can be arranged coaxially about the injection needle (4) and which, together with the injection needle (4) held within the protective sleeve (5), can be moved from the initial position in the proximal direction, in particular, only in the proximal direction relative to the container (1, 1d,), and the protective sleeve (5) can be non-rotatably connected to the container (1, 1d) in the mixing position and can be rotated relative to the mixing device in order to mix the active substance with the dilution liquid for the active substance. |
