OG exemplary drawing
 
1. An injector device for delivering a medicament into a patient's body, comprising:
a syringe cartridge comprising a housing including a proximal end, a distal end, and defining an interior, the cartridge further comprising a piston slidably disposed within the interior for delivering the medicament within the interior through an outlet in the distal end;
a syringe driver comprising a plunger for advancing the piston within the interior of the housing, a source of pressurized fluid, and an actuator member for opening a flow path at least partially between the source and the plunger to advance the plunger and the piston to deliver the medicament from the interior of the housing;
one or more sensors operatively coupled to the plunger to measure displacement of the plunger;
a processor coupled to the one or more sensors for analyzing signals from the one or more sensors to measure a volume of medicament delivered from the outlet based at least in part on the displacement of the plunger; and
an output device coupled to the processor for providing one or more outputs related to the volume of medicament delivered from the outlet;
wherein the output device comprises a light source coupled to the processor and configured to provide visible indications related to activation and operation of the device,
wherein the light source comprises a multiple-color LED configured to emit a first color to indicate when medicament is initially delivered from the cartridge, and a second color when the processor receives a start signal to indicate when medicament is being delivered to a target location, and
wherein the multiple-color LED is configured to emit a third color when the processor confirms that a predetermined dose has been delivered to the target location.
