摘要：
Drug-delivery devices may utilize electrolysis pumps to push a plunger so as to deliver drug from a reservoir. The volume and/or rate of drug delivery may be monitored based on pressure measurements in the pump chamber. Pressure signatures characteristic of end-of-dose and occlusion events may be used to detect when plunger movement stops.
