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.

A system for monitoring a fluid medicament delivery device, the system comprising:
- a patient attachment unit comprising a pressure sensor chamber disposed along a basal flow path, wherein the pressure sensor chamber comprises a sensor membrane;
- and
- an indicator unit configured to be detachably coupled to the patient attachment unit, wherein the indicator unit comprises a pressure sensor in communication with the pressure sensor chamber.
A system for monitoring a fluid medicament delivery device, the system comprising:
- a patient attachment unit comprising a mounting platform and a pressure sensor chamber disposed along a basal flow path, wherein the pressure sensor chamber comprises a sensor membrane;
- and
- an indicator unit configured to be detachably coupled to the patient attachment unit, wherein the indicator unit comprises a pressure sensor disposed in a well having a raised lip, wherein the pressure sensor is in communication with the pressure sensor chamber,
- wherein the raised lip is configured to abut the mounting platform to form an ambient air channel between the patient attachment unit and the indicator unit.
A method for monitoring a fluid medicament delivery device, the method comprising:
- providing a patient attachment unit comprising a pressure sensor chamber disposed along a basal flow path;
- providing an indicator unit configured to be detachably coupled to the patient attachment unit, wherein the indicator unit comprises a pressure sensor in communication with the pressure sensor chamber;
- and
- determining a pressure condition in the basal flow path.
