1. A medicament delivery device comprising:
a sensor module comprising:
a sensor housing, and
at least one sensor disposed in the sensor housing; and
an injector module comprising:
an injector module housing,
a reservoir disposed in the injector module housing, the reservoir adapted to be filled with a medicament to be delivered to a patient,
a cannula adapted to (i) fluidically connect with the reservoir and (ii) pass into a subcutaneous tissue,
a needle initially disposed in a lumen defined by the cannula and adapted to pass into the subcutaneous tissue, and
a coupling mechanism adapted to couple the injector module to the sensor module, the coupling mechanism comprising a latch,
wherein the injector module is adapted to (i) be coupled to the sensor module during injection of the cannula and the needle into the subcutaneous tissue and during delivery of the medicament and (ii) be removed from the sensor module after the delivery of the medicament.
