Patent ID: 7731686

Claim:
An apparatus, comprising: a medicament delivery device configured to deliver a medicament into a body, the medicament delivery device including a housing defining an interior region configured to contain a medicament container; a medicament delivery mechanism disposed within the interior region, the medicament delivery mechanism configured to produce a force acting on the medicament container when actuated; an electronic circuit system including a switch disposed on a printed circuit board, the electronic circuit system configured to output an electronic signal associated with a use of the medicament delivery device when actuated, the electronic circuit system configured to be actuated when the switch is moved from a first state to a second state, the electronic circuit system coupled to an outer surface of the housing such that the electronic circuit system is exterior to the interior region defined by the housing; an actuator configured to be moved between a first position and a second position, a first portion of the actuator disposed outside of the housing, the first portion of the actuator configured to tear a portion of the printed circuit board to irreversibly move the switch from the first state to the second state when the actuator is moved from the first position to the second position, a second portion of the actuator configured to engage a portion of the delivery mechanism to actuate the delivery mechanism when the actuator is moved between the first position and the second position; and a locking member engaged with a portion of the actuator to limit movement of the actuator when the locking member is in a first locking member position.
