DEVICE FOR DELIVERING A MEDICAMENT
First Claim
1. A device for delivery of medicament, comprising:
- a) an elongated housing a proximal end and a distal end;
b) a container mounted within the housing containing a liquid medicament and a stopper slidably arranged within the container;
c) a tubular member slidably arranged within the housing;
d) an actuator comprising, a resilient member;
a plunger rod having a proximal end in contact with the stopper and a distal end being operably connected to the resilient member, where the plunger rod has longitudinally stepped dose grooves corresponding to a plurality of fixed doses; and
a carrier fixedly arranged to an inner surface of the housing and configured not to move axially relative to the housing; and
e) a dose setting mechanism comprising a selector ring axially fixed relative to the housing, the ring rotatable relative to the housing to select one of the plurality of predetermined fixed doses through engagement of the selector ring with the stepped dose grooves.

Abstract
A device for delivery of medicament, which device comprises an elongated housing; a container mounted within said housing and adapted to contain liquid medicament; a stopper slidably arranged within said container; and actuating means comprising a resilient member, a driving means having one end connected to the stopper and a second end being operably connected to the resilient member, retaining means for releasably retaining said driving means in a first position where said resilient member has an accumulated energy, and activating means operably connected to said retaining means for releasing said driving means to a second position, upon actively operation by an user, such that said accumulated energy is transferred to the driving means for driving the stopper a predetermined distance within the container whereby the medicament within said container is delivered characterized in that the resilient member is a variable force spring adapted for generating a predetermined sequence of at least two different force profiles during the medicament delivery.
