1. A system for monitoring a fluid medicament delivery device, the system comprising:
- a patient attachment unit for independently setting a flow rate of a fluid medicament contained therein; and
an indicator unit, adapted to be detachably coupled to the patient attachment unit, for monitoring a parameter of interest of the fluid medicament, the indicator unit comprising;
a sensor for monitoring at least one of a pressure and the flow rate of the fluid medicament;
wherein the indicator unit is not adapted to change the flow rate of the fluid medicament in the patient attachment unit.

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.

16. A method for monitoring a fluid medicament delivery device comprising a patient attachment unit and an indicator unit (i) adapted to be detachably coupled to the patient attachment unit and (ii) comprising a sensor, the method comprising:
-
independently setting a flow rate of a fluid medicament with the patient attachment unit comprising a reservoir for receiving the fluid medicament therein, wherein the indicator unit is not adapted to change the flow rate of the fluid medicament in the patient attachment unit; and monitoring at least one of a pressure and the flow rate of the fluid medicament with the sensor. - View Dependent Claims (17, 18, 19, 20)
