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.
Claims30
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 sensing module for receiving a signal from a sensor located in the patient attachment unit, the signal indicating at least one of a pressure and a flow rate of the fluid medicament;
- a status determination module for determining a status of the fluid medicament delivery device based at least in part on the received signal;
- and
- a notification module for notifying a patient of the status,
- wherein the indicator unit is not adapted to change the flow rate of the patient attachment unit.
A method for monitoring a fluid medicament delivery device comprising a patient attachment unit and an indicator unit adapted to be detachably coupled to the patient attachment unit, the method comprising:
- independently setting a flow rate of a fluid medicament with a patient attachment unit comprising a reservoir for receiving the fluid medicament therein;
- sensing, during a sensing mode, at least one of a pressure and a flow rate of the fluid medicament with a sensor located in a separate indicator unit lacking components for changing the flow rate;
- determining a status of the fluid medicament delivery device based at least in part on a result of at least one of the pressure and the flow rate;
- and
- notifying the patient of the status.
