Abstract
Included are systems and methods for determining a fill level of an inflow-less flexible medicine reservoir as a source for medicine, where the inflow-less flexible medicine reservoir has a monotonically decreasing fill level. Some embodiments of a device include 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. Similarly, some embodiments of the device additionally include 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 for determining the fill level of the inflow-less flexible medicine reservoir from an output signal of the release detector.
