Abstract

A drug delivery device includes a housing. The housing contains a syringe, and the syringe includes a container containing a liquid medicament. The container includes an aperture at a distal end and through which the liquid medicament can be dispensed. The syringe includes a stopper within the container. The stopper is moveable between a first longitudinal position and a second longitudinal position relative to the container, to cause dispensing of the liquid medicament through the aperture. The syringe includes at least one identifying means identifying the liquid medicament.

Claims

1-16. -16. (canceled)

17. A drug delivery device comprising:

a housing; and

a syringe contained in the housing, the syringe comprising;

a container containing a liquid medicament, the container comprising an aperture at a distal end thereof and through which the liquid medicament can be dispensed;

a stopper within the container, the stopper moveable between a first longitudinal position and a second longitudinal position relative to the container to cause dispensing of the liquid medicament through the aperture; and

at least one identifier identifying the liquid medicament.

18. The drug delivery device of claim 17, wherein the at least one identifier is arranged at a distal end of the syringe.

19. The drug delivery device of claim 17, wherein the syringe further comprises a needle shield, wherein the needle shield comprises a hole through which the liquid medicament is to be dispensed, and wherein the at least one identifier is arranged on an outer surface of the needle shield.

20. The drug delivery device of claim 19, wherein the outer surface of the needle shield comprises a front face, wherein the hole is arranged on the front face, and wherein the at least one identifier is arranged on the front face.

21. The drug delivery device of claim 19, wherein the at least one identifier comprises a printed surface.

22. The drug delivery device of claim 19, wherein the at least one identifier comprises a laser marked surface.

23. The drug delivery device of claim 19, wherein the at least one identifier comprises a pin mounted on the needle shield.

24. The drug delivery device of claim 23, wherein the pin is mounted in the hole of the needle shield.

25. The drug delivery device of claim 24, wherein the pin comprises a head and a protrusion arranged on the head, wherein the protrusion is configured to be mounted in the hole of the needle shield.

26. The drug delivery device of claim 17, wherein the at least one identifier comprises a marking printed on the container.

27. The drug delivery device of claim 26, wherein the marking is printed on the container using UV light.

28. The drug delivery device of claim 26, wherein the marking is printed on the container by laser marking.

29. The drug delivery device of claim 26, wherein the marking comprises a barcode.

30. The drug delivery device of claim 26, wherein the marking comprises a ring arranged around an outer surface of the container.

31. A method of manufacturing a drug delivery device that includes a housing and a syringe contained in the housing, wherein the syringe comprises

a container containing a liquid medicament, the container comprising an aperture at a distal end thereof and through which the liquid medicament can be dispensed, and a stopper within the container, the stopper moveable between a first longitudinal position and a second longitudinal position relative to the container to cause dispensing of the liquid medicament through the aperture,

wherein the method comprises providing the syringe with at least one identifier identifying the liquid medicament contained in the container.

32. A method for identifying a liquid medicament contained within a drug delivery device, the method comprising:

detecting, by a sensor, at least one identifier on a syringe contained in a housing of the drug delivery device; and

in response to detecting the at least one identifier, identifying the liquid medicament using the detected at least one identifier.

33. The method of claim 32, wherein identifying the liquid medicament using the detected at least one identifier comprises:

comparing the detected at least one identifier with a database, the database storing one or more identities of liquid medicaments; and

determining that there is a match between the detected at least one identifier and one of the one or more identities of liquid medicaments stored in the database.

34. The method of claim 32, wherein the at least one identifier comprises a printed surface.

35. The method of claim 32, wherein the at least one identifier comprises a laser marked surface.

36. The method of claim 32, wherein the at least one identifier comprises a pin mounted on a needle shield of the syringe.
