Abstract

Claims (27)

1. A cartridge configured to be received in a pharmaceutical delivery device comprising a housing, the cartridge comprising:

a light pipe section that acts as a light pipe and that has an input location; and

a light diffusing section optically coupled to the light pipe, wherein at least a portion of the light diffusing section extends outside of at least a portion of an outer surface of the housing.

2. The cartridge of claim 1 , wherein when the input location is optically coupled to a light source, at least some light from the light source that enters the input location and is diffused at the light diffusing section.

3. The cartridge of claim 1 , wherein a wall of the cartridge includes the light diffusing section.

4. The cartridge of claim 1 , further comprising a flange at a distal end of the cartridge, wherein the light diffusing section comprises the flange.

5. The cartridge of claim 1 , wherein at least a portion of the light diffusing section has a surface roughness to diffuse light.

6. The cartridge of claim 1 , further comprising at least one protruding element, wherein the light diffusing section comprises the at least one protruding element.

7. The cartridge of claim 6 , wherein the at least one protruding element at least partially surrounds an outer surface of the cartridge.

8. The cartridge of claim 6 , wherein the at least one protruding element comprises a plurality of protruding elements equidistantly spaced apart along a longitudinal axis of the cartridge.

9. The cartridge of claim 1 , wherein the light diffusing section comprises at least one circular bulge.

10. The cartridge of claim 1 , wherein the light diffusing section comprises at least one light diffusing slot.

11. A cartridge configured to be received in a pharmaceutical delivery device comprising a housing, the cartridge comprising:

a light pipe section that acts as a light pipe and that has an input location; and

a layer at least partially lining a surface of the cartridge, the layer optically coupled to the light pipe, and the layer being at least partially transparent.

12. The cartridge of claim 11 , wherein at least a portion of the layer includes an adhesive for attaching the layer onto the surface of the cartridge.

13. The cartridge of claim 11 , wherein the layer includes an indicia.

14. The cartridge of claim 11 , wherein the layer is configured to diffuse light having a wavelength associated with at least one visual perceptive property of the pharmaceutical.

15. The cartridge of claim 11 , wherein the layer is on an inner surface of the cartridge.

16. The cartridge of claim 11 , wherein the layer is on an outer surface of the cartridge.

17. The cartridge of claim 1 , wherein the housing defines a window, and the portion of the light diffusing section extends outside of window.

18. The cartridge of claim 17 , further comprising a dome that covers the portion of the light diffusing section that extends outside of the window.

19. A cartridge configured to be received in a pharmaceutical delivery device comprising a housing, the cartridge comprising:

a light pipe section that acts as a light pipe and that has an input location; and

a light diffusing section optically coupled to the light pipe,

wherein the light diffusing section is made from the same material as the cartridge.

20. The cartridge of claim 19 , wherein at least a portion of the light diffusing section extends outside of at least a portion of an outer surface of the housing.
