Device and Method for Determining the Fill Level of a Flexible Medicine Reservoir
First Claim
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.

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.

13. A method for calculating 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:
-
determining when a threshold fill level of the inflow-less flexible medicine reservoir has been reached; determining an amount of medicine taken from the inflow-less flexible medicine reservoir since the threshold fill level has been reached; calculating the fill level by subtracting the amount of medicine taken from the inflow-less flexible medicine reservoir from the threshold fill level; and providing a fill level signal related the fill level. - View Dependent Claims (14)
