Abstract
A pharmaceutical delivery device includes a cartridge containing a fluid. The cartridge includes a light pipe section having an input location and a light diffusing section optically coupled to the light pipe. A light source is optically coupled to the cartridge at the input location to the light pipe, such that at least some light from the light source entering at the input location is diffused at the light diffusing section.
Claims11
A method for indicating a state of a pharmaceutical delivery device to a user, the method comprising:
- optically coupling a light source to a cartridge, the cartridge comprising:
- a reservoir containing a fluid;
- a light pipe with a light input location;
- and
- a light diffusing section optically coupled to the light input location;
- positioning the light source and the cartridge in a housing of the pharmaceutical delivery device, the housing comprising a window;
- aligning the light diffusing section with the window of the housing to provide an optical pathway between at least part of the light diffusing section and an outside of the housing;
- and
- operating the light source to indicate a state of the pharmaceutical delivery device via diffusion of light from the light source through the light diffusing section and to the outside of the housing through the window.

A method of manufacturing a pharmaceutical delivery device, the method comprising:
- forming a cartridge, the cartridge comprising:
- a reservoir;
- a light pipe comprising an input location;
- and
- a light diffusing section optically coupled to the light pipe;
- filling the reservoir of the cartridge with a fluid;
- providing a housing defining a void and comprising a window that overlaps with the void;
- positioning the cartridge within the void of the housing such that the light diffusing section is aligned with the window of the housing to provide an optical pathway between at least part of the light diffusing section and an outside of the housing;
- positioning a light source within the housing;
- and
- optically coupling the light source to the light pipe through the input location such that when light from the light source enters the input location the light is diffused at the light diffusing section and exits to the outside of the housing through the window.
