INJECTION DEVICE WITH BATTERY COMPARTMENT HAVING ELEMENTS PREVENTING POLARITY REVERSAL AND FACILITATING BATTERY INSERTION/REMOVAL

摘要

A medicament delivery device (1) comprises a battery compartment (3) for receiving a battery (5) through an opening provided in a case (2) of the medicament delivery device (1). The battery (5) has a protruding terminal (5a) with a contact surface (5c) and the medicament delivery device a is characterised in that the battery compartment (3) comprises a wall (13) having a recess (12) for receiving the protruding terminal (5a) to make electrical connection with a contact (15) positioned within or behind the recess (12). Moreover, the recess (12) comprises a recess surface (12a) which is at least partly inclined with respect to the surface of the contact (15) such that the recess angle (12b) between the inclined recess surface (12a) and the surface of the contact (15) of the battery compartment (3) is obtuse.
