1. A method of measuring injection of a liquid medicine, comprising:
a sensor in a sensor flange removably coupled to a syringe body measuring an injection characteristic during an injection of a liquid medicine from the syringe body;
a processor in the sensor flange analyzing the injection characteristic to determine an occurrence of an injection event;
a mounting sensor in the sensor flange detecting when the sensor flange is removably coupled to the syringe body;
the sensor flange delivering an alarm once the injection of the liquid medicine has been completed to prevent the sensor flange from being disposed of prematurely; and
the processor silencing the alarm once the mounting sensor detects the finger flange has been removed from the syringe body.
