## 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.

## Claims

### Claim 1

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.

### Claim 2 (depends on 1)

The method of claim 1, wherein the state of the pharmaceutical delivery device comprises at least one of an ongoing delivery state, a stop delivery state, an on or off state, or a device malfunction state.

### Claim 3 (depends on 1)

The method of claim 1, wherein the state of the pharmaceutical delivery device comprises an inventory status of the fluid.

### Claim 4 (depends on 1)

The method of claim 1, wherein operating the light source comprises continuously or intermittently emitting light from the light source.

### Claim 5 (depends on 1)

The method of claim 1, wherein operating the light source comprises changing a color of the light source.

### Claim 6

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.

### Claim 7 (depends on 6)

The method of claim 6, wherein forming the cartridge comprises molding the cartridge.

### Claim 8 (depends on 7)

The method of claim 7, wherein molding the cartridge comprises molding the cartridge using a polymer.

### Claim 9 (depends on 6)

The method of claim 6, further comprising operatively coupling the light source with control circuitry and programming to operate the light source according to a state of the pharmaceutical delivery device.

### Claim 10 (depends on 9)

The method of claim 9, further comprising programming the control circuitry to adjust light generated by the light source according to an inventory status of the fluid.

### Claim 11 (depends on 6)

The method of claim 6, wherein the light diffusing section is positioned to provide a view of a physical indicator of an inventory state of the fluid.
