Injection device

A protective cap for a dispensing end of an injection device, the protective cap comprising:

• a cap body;
• a cap electrode attached to the cap body;
• and
• a first electronic circuit attached to the cap body and electrically connected to the cap electrode, the first electronic circuit comprising a transceiver operable to transmit data to an external analysis device,
• wherein the first electronic circuit is configured to be electrically connected to a second electronic circuit of the injection device via the cap electrode when the protective cap is attached to the injection device, wherein the second electronic circuit is configured to capture dose dispensing related data from a drive mechanism of the injection device.

A kit configured to provide an injection device for administering a dose of a liquid medicament, the kit comprising:

• a disposable elongated housing having a dispensing end and being configured to accommodate a cartridge filled with the liquid medicament;
• a drive mechanism arranged inside the elongated housing and configured to operably engage with the cartridge for expelling of the dose of the liquid medicament from the cartridge via the dispensing end;
• a reusable protective cap detachably attached to the housing to cover the dispensing end;
• a first electronic circuit attached to the protective cap and electrically connected to a cap electrode arranged on the protective cap, wherein the first electronic circuit comprises a transceiver operable to transmit data to an external analysis device;
• and
• a second electronic circuit arranged inside the housing, coupled to the drive mechanism and electrically connected to a housing electrode located on the housing,
• wherein the first and the second electronic circuits are electrically connectable to each other via the cap electrode and the housing electrode, the cap electrode and the housing electrode being configured to get in mutual contact when the protective cap is attached to the housing, and
• wherein the second electronic circuit is void of a transceiver.
