Abstract
The invention relates to a drug delivery device for selecting and dispensing a number of user variable doses of a medicament. The device comprises a dosing element (40, 30), which rotates in a first direction during dose selecting and rotates in a second, opposite direction during dose dispensing, and a display (60) for indicating the selected dose. The display (60) comprises at least one belt (61, 62) having symbols for indicating the selected dose and being coupled to the dosing element (40, 130) such that a rotation of the dosing element (40, 130) spools the belt (61, 62).
Claims17
A drug delivery device for selecting and dispensing a number of user variable doses of a medicament, the drug delivery device comprising:
- an outer housing comprising a cylindrical portion;
- a dosing element which rotates in a first direction during dose selecting;
- a display for indicating a selected dose, wherein the display comprises at least one belt having symbols, colors, or texture for indicating the selected dose, the at least one belt being coupled to the dosing element such that a rotation of the dosing element spools the at least one belt, wherein the dosing element rotates in a second, opposite direction during dose dispensing;
- and
- a striker plate having a curvature less than a curvature of the cylindrical portion of the outer housing, wherein a portion of the at least one belt is simultaneously guided on the striker plate and visible through the outer housing.

- a striker plate having a curvature less than a curvature of the cylindrical portion of the outer housing, wherein the at least one belt is guided on the striker plate,
- wherein the at least one belt comprises:
- a belt which is directly coupled to the dosing element, and
- a further belt which is indirectly coupled to the dosing element,
- wherein the belt is coupled to the dosing element such that a first continuous rotation of the dosing element is translated into an intermittent motion of the belt, and wherein the further belt is coupled to the dosing element such that a second continuous rotation of the dosing element is translated into a continuous motion of the further belt.
