1. A medication delivery device comprising:
a cannula;
a sensor configured to sense flow of medication from the medication delivery device (MDD) through the cannula to a patient at a delivery site;
a processing device configured to receive sensor data from the sensor;
a wireless communication circuit configured to transmit the sensor data from the MDD to an external device on a wireless link;
an indicator; and
a switch configured to provide a supply of power from a power source to the sensor, the processing device, and the wireless communication circuit when activated upon user initiation of medication delivery, and to terminate the supply of power upon user placement of the MDD in a non-operational state;
wherein the processing device is configured, upon being powered, to:
operate the indicator to indicate a first state corresponding to the MDD being powered on and not connected to the external device via the wireless link;
control pairing of the MDD to the external device and, once the external device is paired with the MDD, to operate the indicator to indicate a second state corresponding to the MDD being powered on and connected to the external device via the wireless link;
transmit the sensor data to the external device via the wireless link during the second state;
and
operate the indicator to indicate that the cannula may be removed from the delivery site when a predetermined amount of time has elapsed after the sensor data that the processing device receives corresponds to a sensed flow rate of medication from the MDD being zero.
