Abstract

A drug injection device ( 10 ) including a housing ( 12 ) for holding a container ( 20 ) having a needle ( 24 ) for penetrating skin and a plunger ( 42 ) for expelling a drug stored in the container. The device includes visual and/or audible indicators for indicating that the correct depth of needle penetration has been achieved and that drug injection/extrusion has been started and/or completed. The device may further include a label ( 140 ) for visually confirming the quality of the drug contained therein. Alternatively, a tray ( 110 ) may be provided for receiving the drug injection device, which allows the quality of the drug contained therein to be visually confirmed.

First claim

What is claimed is:

1. A drug injection device comprising:
a housing for holding a container, the container storing a drug therein, the housing including at least one window that allows viewing of the drug in the container; and
a drug test surface removably disposed over at least a portion of the housing and immediately adjacent to at least a portion of the at least one window in the housing, such that the drug in the container can be compared against the drug test surface to determine at least one of a clarity or a color of the drug by viewing the drug against the drug test surface through the at least one window of the housing.

2. The drug injection device of claim 1 , wherein the at least one window comprises two or more discrete windows that allow viewing of the drug in the container.

3. The drug injection device of claim 1 , wherein the at least one window comprises a transparent 360 degree section of the housing of the container.

4. The drug injection device of claim 1 , wherein the drug test surface is provided by a removable label, the label having first and second sections, the second section of the label that defines the drug test surface.

5. The drug injection device of claim 4 , wherein the drug test surface of the second section includes an area of a first color for testing one of the clarity or the color of the drug.

6. The drug injection device of claim 5 , wherein the drug test surface of the second section includes an area of a second color for testing the other one of the clarity or the color of the drug.

7. The drug injection device of claim 4 , wherein the label covers at least a portion of the at least one window.

8. The drug injection device of claim 7 , wherein the second section of the label includes an inner surface that defines the drug test surface; and removal of the first section of the label from the housing exposes the drug test surface of the second section of the label to be visible through the at least one window.

9. The drug injection device of claim 4 , wherein the first section of the label has a first instruction to remove the first section to check the drug and a second instruction to determine the at least one of the clarity or the color of the drug.

10. The drug injection device of claim 9 , wherein the label further includes a third section having a first instruction to remove the third section of the label if the at least one of the clarity or the color of the drug is determined to be proper and a second instruction to not use the device if the at least one of the clarity or the color of the drug is determined to be improper.

11. The drug injection device of claim 4 , wherein the label includes a pull tab.

12. The drug injection device of claim 4 , wherein the container includes a needle for penetrating skin and dispensing the drug stored in the container, at least a portion of the needle extending out of the housing and further comprising a cap for enclosing the at least portion of the needle.

13. The drug injection device of claim 12 , wherein the label at least partially covers the cap acting as a tamper evident feature.
