Abstract
A fluid medicament delivery device includes a patient attachment unit, containing the fluid medicament, and an indicator unit adapted to be detachably coupled to the patient attachment unit. A method for monitoring the fluid medicament includes independently setting a flow rate of a fluid medicament with the patient attachment unit. A pressure and/or a flow rate of the fluid medicament is sensed with a sensor located in a separate indicator unit in a sensing mode. A status of the fluid medicament delivery device is determined based at least in part on the pressure and/or the flow rate.
