The visual identification coding includes a cartridge containing a drug and a light source located on the cartridge to visually indicate that the correct cartridge has been inserted into the drug delivery device. The light source may be a light emitting diode (LED), a surface mount diode (SMD), or an organic light emitting diode (OLED). A cartridge holder may also be included to receive the cartridge. In another embodiment, the light source may be located on the cartridge holder or a dose setting member. ## Claims ### Claim 1 A drug delivery device comprising: a cartridge containing a drug; a cartridge holder to receive the cartridge; and a light source configured to illuminate and provide visual indication when the correct type of cartridge has been correctly paired with the cartridge holder or that the correct type of cartridge holder has been correctly paired with and inserted into the drug delivery device. ### Claim 2 (depends on 1) The drug delivery device of claim 1, wherein the correct cartridge or the correct cartridge holder contain the correct type of medicament. ### Claim 3 (depends on 1) The drug delivery device of claim 1, wherein the light source is located on the cartridge to visually indicate that the correct cartridge has been inserted into the drug delivery device. ### Claim 4 (depends on 1) The drug delivery device of claim 1, wherein the cartridge holder includes the light source to visually indicate that the correct cartridge holder has been inserted into the drug delivery device. ### Claim 5 (depends on 1) The drug delivery device of any of claim 1 further comprising a dose setting member which includes the light source. ### Claim 6 (depends on 1) The drug delivery device of claim 1 wherein the light source comprises one or more of a light emitting diode (LED), a surface mount diode (SMD), or an organic light emitting diode (OLED). ### Claim 7 (depends on 1) The drug delivery device of claim 1 wherein the light source is activated by a trigger upon insertion of the correct cartridge or the correct cartridge holder into the drug delivery device. ### Claim 8 (depends on 1) The drug delivery device of claim 1 wherein the light source comprises a blue light source to indicate that the inserted cartridge is correct for the drug delivery device. ### Claim 9 (depends on 1) The drug delivery device of claim 1 wherein the cartridge holder is removably secured to the cartridge. ### Claim 10 (depends on 1) The drug delivery device of claim 1 wherein the light source includes one or more colored lights that indicates that a specific drug is contained in the cartridge. ### Claim 11 (depends on 10) The drug delivery device of claim 10 wherein the light source includes at least two lights of different colors to indicate that a specific drug is contained in the cartridge. ### Claim 12 (depends on 1) The drug delivery device of claim 1 wherein the light source comprises only one light. ### Claim 13 (depends on 1) The drug delivery device claim 1 wherein the light source comprises a plurality of lights. ### Claim 14 (depends on 1) The drug delivery device of claim 1 further including a cartridge sleeve secured to the cartridge. ### Claim 15 A drug delivery device comprising: a cartridge containing a drug; a cartridge holder to receive the cartridge; and a light source to visually indicate that the correct cartridge or the correct cartridge holder has been inserted into the drug delivery device and contains the correct type of medicament. ### Claim 16 A drug delivery device comprising: a cartridge containing a drug; a cartridge holder to receive the cartridge; and a light source to visually indicate that the correct cartridge or the correct cartridge holder has been inserted into the drug delivery device, wherein the light source is located on the cartridge to visually indicate that the correct cartridge has been inserted into the drug delivery device or is located on the cartridge holder to visually indicate that the correct cartridge holder has been inserted into the drug delivery device. ### Claim 17 A drug delivery device comprising: a cartridge containing a drug; a cartridge holder to receive the cartridge; a cartridge sleeve secured to the cartridge; and a light source to visually indicate that the correct cartridge or the correct cartridge holder has been inserted into the drug delivery device.
