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.

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; andan 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. 2. The system of claim 1, wherein the patient attachment unit is adapted to be attached to a skin surface of the patient. 3. The system of claim 1, wherein the sensor comprises a MEMS sensor. 4. The system of claim 1, further comprising an initialization module for performing a system initialization test. 5. The system of claim 4, wherein the system initialization test comprises a battery status test. 6. The system of claim 5 further comprising a notification module adapted to notify the patient based on a result of the battery status test. 7. The system of claim 5, wherein a result of the battery status test is based at least in part on at least one of a volume of the fluid medicament and an amount of time. 8. The system of claim 1 further comprising a notification module for notifying a patient of a status of the fluid medicament delivery device, wherein the status comprises a fault condition based at least in part on a volume of the fluid medicament, the pressure of the fluid medicament, the flow rate of the fluid medicament, a hardware fault, and an amount of time. 9. The system of claim 8, wherein the fault condition comprises at least one of an out-of-fluid condition and a time limit condition. 10. The system of claim 1 further comprising a notification module adapted to notify the patient of a status of the fluid medicament delivery device, wherein the status comprises a system-OK condition. 11. The system of claim 1 further comprising a notification module adapted to notify the patient of a status of the fluid medicament delivery device, wherein the status comprises at least one of an occlusion condition and a low-reservoir volume condition. 12. The system of claim 1, wherein the patient attachment unit comprises a variable-volume chamber and the fluid medicament is at least partially contained therein. 13. The system of claim 12, wherein the variable-volume chamber unit comprises a flexible member and wherein a movement of the flexible member is sensed by the sensor. 14. The system of claim 1 further comprising a notification module adapted to notify the patient of a status of the fluid medicament delivery device, wherein the notification module further comprises an alarm. 15. The system of claim 14, wherein the alarm comprises at least one of an audible alarm, a visual alarm, and a tactile alarm. 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; andmonitoring at least one of a pressure and the flow rate of the fluid medicament with the sensor. 17. The method of claim 16, wherein the patient attachment unit is adapted to be attached to a skin surface of the patient. 18. The method of claim 16, further comprising initiating the sensor upon receipt of an interrupt request. 19.
