Injection device (angled trigger)

摘要

An injection device 110 comprises a housing 112 defining a first axis 101, and adapted to receive a syringe with a needle where the syringe is movable between a retracted position in which the needle is contained within the housing 112 and an extended position in which the needle extends from the housing through an exit aperture 118. A drive 120 acts upon the syringe when released by a trigger 114. The trigger 114 is rotatable from a rest position in which the drive 120 is retained to an active position in which the drive 120 is released. The trigger 114 is mounted on a pivot 115 and has a partially concave surface 201 shaped such that a user can apply a force in a direction substantially parallel to the first axis 101 to rotate the trigger 114 from its rest position to its active position. The force is applied by the movement of the user's hand across the housing 112 and over the trigger 114. Such an injection device provides improved handling and ease of operation.
