Drug delivery dose indicator

A dose delivery device having a transponder for determining a characteristic of the dose delivery device when delivering a dose of medicament, the dose delivery device comprising:

• a body housing a reservoir within the body for containing the medicament;
• an actuator configured for engagement by a user;
• a push rod coupled to the actuator and extending through the body, the push rod configured to dispense the medicament from the reservoir;
• a plunger located distal to the push rod and located adjacent to the reservoir;
• and
• the transponder positioned within the body, the transponder comprising:
• a sensor configured to detect at least one parameter of the dose delivery device and generate a signal indicative of the parameter;
• a processor operably coupled to the sensor and configured to process the signal;
• and
• an indicator unit operably coupled to the processor and configured to generate an output based on the signal, wherein the output is perceivable by a user.

A dose delivery system comprising:

• a dose delivery device, including:
• a body having a reservoir located within a distal region of the body, wherein the reservoir is configured to contain a medicament;
• a push rod having a plunger located at a distal end of the push rod, wherein the plunger defines a proximal end of the reservoir, and wherein the push rod and the plunger are cooperatively configured to dispense the medicament from the reservoir;
• an actuator operably connected to a proximal end of the push rod and configured to advance the push rod in a distal direction through the body;
• and
• a cannula attached to the distal end of the body through which the medicament from the reservoir is dispensed;
• and
• a transponder, including:
• a sensor dimensioned to be positioned within the body and configured to detect at least one parameter of a dose of the medicament being dispensed from the reservoir, wherein the sensor is configured to generate a signal indicative of the parameter;
• a processor operably coupled to the sensor and configured to process the signal;
• an indicator unit operably coupled to the processor and configured to generate an output based on the signal, wherein the output is perceivable by a user;
• and
• a battery configured to provide power for at least one of the sensor, the processor, and the indicator unit.
