Abstract
An administration device comprises a container and a mixing device for mixing an active substance (in a first chamber) with a dilution liquid (in a second chamber). The container has a membrane seal at one end and is combined with a mixing device for mixing the active substance. The administration device has an injection needle unit with a distal needle portion facing away from the container for piercing the skin, and disposed opposite thereto is a proximal needle portion facing the membrane when the administration device is in the initial position, which is thrust through the membrane into the container in a mixing position. The administration device includes a protective sleeve arranged coaxially about the injection needle, movable from the initial position only in the proximal direction relative to the container. The protective sleeve can be non-rotatably connected to the container in the mixing position and rotated relative to the mixing device to perform mixing.
