The device comprises a transporting and transferring container, a measuring element, and an adjusting element for influencing a dispensing of the medium by way of a connection to an interior space. The transporting and transferring container has a reservoir for receiving the medium. The reservoir is closed by a displaceable element. The displaceable element is movably mounted in relation to the reservoir. A relative positioning of the displaceable element in relation to the reservoir determines the interior space of the reservoir available for receiving the medium. The measuring element senses the relative positioning of the displaceable element in relation to the reservoir. The measuring element and the adjusting element interact so that the dispensing of the medium is influenced by the relative positioning sensed by the measuring element. ## Claims ### Claim 1 A device for the dosed dispensing of a fluidic medium, the device comprising: at least one transporting and transferring container, wherein the transporting and transferring container has at least one reservoir for receiving the fluidic medium, the reservoir has at least one displaceable element that is movably mounted in relation to the reservoir and wherein a relative positioning of the displaceable element in relation to the reservoir determines an interior space of the reservoir available for receiving the fluidic medium; at least one measuring element, wherein the measuring element senses the relative positioning of the displaceable element in relation to the reservoir; and at least one adjusting element for influencing the dispensing of the fluidic medium by way of at least one fluid connection to the interior space; wherein the measuring element and the adjusting element interact so that the dispensing of the fluidic medium is influenced by the relative positioning sensed by the measuring element. ### Claim 2 (depends on 1) The device according to claim 1, wherein the fluidic medium is a fluidic therapeutic and/or diagnostic agent for an insulin pump. ### Claim 3 (depends on 1) The device according to claim 1, wherein the measuring element generates at least one measuring signal corresponding to the relative positioning. ### Claim 4 (depends on 3) The device according to claim 3, further comprising, at least one controller, wherein the controller controls the adjusting element in an open-loop and/or closed-loop mode by the measuring signal. ### Claim 5 (depends on 1) The device according to claim 1, wherein the displaceable element comprising a stopper which is displaceable in relation to the reservoir. ### Claim 6 (depends on 5) The device according to claim 5, wherein the measuring element senses displacement of the stopper in the reservoir. ### Claim 7 (depends on 6) The device according to claim 6, wherein the displacement of the stopper in the reservoir is a linear displacement. ### Claim 8 (depends on 1) The device according to claim 1, wherein the measuring element senses at least one position of at least one interface between the displaceable element and the fluidic medium. ### Claim 9 (depends on 1) The device according to claim 1, further comprising, at least one housing. ### Claim 10 (depends on 9) The device according to claim 9, wherein the reservoir is movably accommodated in the housing and wherein the displaceable element is fixed in relation to the housing. ### Claim 11 (depends on 9) The device according to claim 9, wherein the measuring element senses a relative positioning of the reservoir in the housing. ### Claim 12 (depends on 1) The device according to claim 1, wherein the device subjects the displaceable element and/or the reservoir to a force so that the fluidic medium is under increased pressure. ### Claim 13 (depends on 1) The device according to claim 1, further comprising, at least one energy unit, wherein the energy unit subjects the fluidic medium in the reservoir to a positive pressure and is a component of the transporting and transferring container. ### Claim 14 (depends on 1) The device according to claim 1, wherein the adjusting element has at least one valve, wherein the valve influences a flow of the fluidic medium through the fluid connection. ### Claim 15 (depends on 14) The device according to claim 14, wherein the valve interrupts the flow of the fluidic medium through the fluid connection. ### Claim 16 (depends on 14) The device according to claim 14, wherein the valve allows the flow of the fluidic medium through the fluid connection. ### Claim 17 (depends on 14) The device according to claim 14, wherein the valve has at
