1. A wearable infusion device comprising:
- a reservoir that holds a liquid medicament, the reservoir having a moveable wall that moves as the medicament volume increases and decreases within the reservoir;
an outlet port that delivers the liquid medicament to a patient;
a pump that displaces a volume of the liquid medicament to the outlet port; and
medicament level indicator including a non-elastic, non-compressible, elongated web having a first end and a second end, the web being fixed at one end with respect to the moveable wall of the reservoir, arranged to move in a first plane with the moveable wall intermediate the first and second ends, and confined at the second end for linear movement in a second plane substantially transverse to the first plane.
