User authentication for a drug delivery device

An electronic circuit for a drug delivery device, the electronic circuit comprising:

• a communication interface operable to wirelessly communicate with a mobile electronic device of a user and configured to receive an identification signal from the mobile electronic device;
• a storage operable to store a user specific data record;
• and
• a processor operatively connected to the communication interface and to the storage and operable to evaluate the identification signal by comparing the identification signal to the user specific data record;
• wherein the processor is operable to enable, disable, trigger, or terminate an execution of an electronically implemented function of the electronic circuit based on an evaluation of the identification signal.

A drug delivery device operable to dispense a medicament, the drug delivery device comprising:

• a housing to accommodate a medicament container filled with the medicament;
• a drive mechanism operatively connectable to the medicament container to expel or to withdraw the medicament from the medicament container;
• and
• an electronic circuit comprising:
• a communication interface operable to wirelessly communicate with a mobile electronic device of a user and configured to receive an identification signal from the mobile electronic device,
• a storage operable to store a user specific data record, and
• a processor operatively connected to the communication interface and to the storage and operable to evaluate the identification signal by comparing the identification signal to the user specific data record,
• wherein the processor is operable to enable, disable, trigger, or terminate an execution of an electronically implemented function of the electronic circuit based on an evaluation of the identification signal.

A supplementary device for a drug delivery device, the supplementary device comprising:

• a fastener for fastening the supplementary device to a first housing of the drug delivery device;
• a second housing;
• and
• an electronic circuit comprising:
• a communication interface operable to wirelessly communicate with a mobile electronic device of a user and configured to receive an identification signal from the mobile electronic device,
• a storage operable to store a user specific data record, and
• a processor operatively connected to the communication interface and to the storage and operable to evaluate the identification signal by comparing the identification signal to the user specific data record,
• wherein the processor is operable to enable, disable, trigger, or terminate an execution of an electronically implemented function of the electronic circuit based on an evaluation of the identification signal.

A method of authenticating a user to use a drug delivery device, the method comprising:

• establishing of a wireless communication link between a communication interface of an electronic circuit coupled to the drug delivery device and to a mobile electronic device;
• receiving, by the communication interface, an identification signal from the mobile electronic device;
• evaluating the identification signal by a processor operatively connected to the communication interface;
• and
• enabling, disabling, triggering, or terminating an execution of an electronically implemented function of the electronic circuit based on an evaluation of the identification signal.
