1. A system for monitoring a fluid medicament delivery device, the system comprising:
- a patient attachment unit for delivering a fluid medicament contained therein to a patient; and
an indicator unit adapted to be coupled to the patient attachment unit, the indicator unit comprising;
a timer adapted to measure a usage time of the system;
a processor in electrical communication with the timer; and
a memory in electrical communication with the processor, the memory comprising instructions which program the processor to;
receive an input from the patient;
in response to the input;
compare the usage time of the system to a first threshold operating time that is based on an expected time of use of the system, the expected time of use being based, at least in part, on a fluid storage capacity of the system, anddetermine if the first threshold operating time has elapsed; and
provide the patient with an appropriate response.

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.

17. A method of operating a fluid medicament delivery device, the method comprising the steps of:
-
measuring a usage time of a system by a non-transitory processor, the system comprising a patient attachment unit for delivering a fluid medicament contained therein to a patient and an indicator unit adapted to be coupled to the patient attachment unit; receiving an input from the patient; in response to the input; comparing the usage time of the system to a first threshold operating time that is based on an expected time of use of the system, the expected time of use being based, at least in part, on a fluid storage capacity of the system, and determining if a first threshold operating time has elapsed; and providing the patient with an appropriate response. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
