Blister advancement mechanism comprising an actuator plate

A dry powder inhaler device (11) comprising a body (1) and a trigger (2) moving on an axial/linear direction in the body, a main drum (5) into which a blister (4) strip having drug-carrying cavities (3) is placed, a gear set (6, 7, 8) which enables to release a drug in the next cavity of the blister strip to be administered with rotating the main drum and around which a protective layer or cover of the blister strip is wound, and additional gears (9, 10) which are in connection with the main drum (5) and around which a main layer of the blister (4) strip is wound, said device being characterized by comprising

• an actuator plate (15) having a first end (12) connected to the trigger and a second end (13) comprising a socket (14) with a size sufficiently large to receive a transmission wheel therein,
• a series of teeth (16) which are aligned in the socket (14) of the actuator plate (15) on the axial/linear direction in which the trigger is moved, and
• a transmission wheel (17) connected to the teeth (16) provided in the socket (14) for converting the axial/linear motion of the trigger (2) into a rotational motion and transferring this motion to main drum (5).
