The medical device (110) has a transport- and transfer receptacle (114) which comprises a container (116) for receiving the fluid medium (112). The container has a displaceable element (120) that is movably mounted relative to the container. A measuring element (164) is arranged to detect the relative positioning of the displaceable element to the container. A control element (150) influences a dispensing of the fluid medium over a fluid connection (142) to an inner space (134) of the container. An independent claim is also included for a method for dosed dispensing of a fluid medium, particularly fluid therapeutic agent or diagnostic agent.
