1. A device for determining a fill level of an inflow-less flexible medicine reservoir as a source for medicine, the inflow-less flexible medicine reservoir having a monotonically decreasing fill level, comprising:

  • a stop surface designed and arranged such that the stop surface contacts the inflow-less flexible medicine reservoir while the inflow-less flexible medicine reservoir is filled above a predetermined level;

    a release detector that generates an output signal indicative of contact between the stop surface and the inflow-less flexible medicine reservoir being released; and

    a processing unit that determines the fill level of the inflow-less flexible medicine reservoir from an output signal of the release detector.
