Abstract

A method and system for proving a drug delivery device. The device comprises a drug delivery device housing and a medicament contained in the drug delivery device housing. A dose dial sleeve is positioned in the housing and is rotatable to set a non-inverted dose of the medicament contained in the medical delivery device. The non-inverted dose may be increased by turning the dose dial sleeve in a direction towards a user of the drug delivery device. The dose medicament may be decreased by rotating the dose dial sleeve in a direction away from the user.

Claims

1. A drug delivery device, said device comprising:

a drug delivery device housing;

a medicament contained in said drug delivery device housing; and

a dose dial sleeve positioned in said housing,

said dose dial sleeve rotatable to set a non-inverted dose of said medicament contained in said medical delivery device;

wherein said non-inverted dose may be increased by turning said dose dial sleeve in a direction towards a user of said drug delivery device.

2. The invention of claim 1 wherein said dose of said medicament may be decreased by rotating said dose dial sleeve in a direction away from said user.

3. The invention of claim 1 wherein said housing further comprises a label, said label representative of said medicament contained in said drug delivery device, said label comprising non-inverted text and readable by said user as said user sets said dose of medication.

4. The invention of claim 1 wherein said housing further includes a viewing window such that during said dose setting operation, a scale representative of said dose is viewable through said viewing window.

5. The invention of claim 1 wherein said dose dial sleeve comprises a scale arrangement, such that as said user sets said dose by turning said dose dial sleeve towards said user, said scale arrangement is viewable in a non-inverted orientation.

6. The invention of claim 1 wherein said drug delivery device is a disposable drug delivery device.

7. The invention of claim 1 wherein said drug delivery device is a reusable drug delivery device.

8. The invention of claim 1 wherein when said user injects said dose, said dose setting element rotates back into said housing and in a direction away from said user.

9. The invention of claim 1 wherein said medicament contained in said medical delivery device is insulin.

10. The invention of claim 1 wherein said insulin comprises a long acting insulin.

11. The invention of claim 1 wherein said medicament contained in said medical delivery device is contained in a cartridge.

12. The invention of claim 11 wherein said cartridge is a removable cartridge.

13. The invention of claim 1 further comprising a colored portion, said color portion indicating that said user sets said dose of medication of said drug delivery device by rotating said dose dial sleeve in a direction towards said user.

14. The invention of claim 13 wherein said color portion is provided on a label.

15. The invention of claim 13 wherein said color portion is provided on said housing.

16. A pen type drug delivery device, said device comprising:

a drug delivery device housing, said housing having a distal end for mounting a needle assembly and a proximal end comprising a dose dial grip;

a cartridge contained in said housing, said cartridge containing a medication;

a dose dial sleeve rotatably mounted in said drug delivery housing and operatively coupled to said dose dial grip,

such that said dose dial grip may be rotated in a direction towards a user of said pen type drug delivery device to set a dose of said medication such that, as said dose dial grip is rotated, both said dose dial grip and said dose dial sleeve translate away from said proximal end of said drug delivery housing, and a non-inverted scale viewable in a window of said housing, said non-inverted scale representative of said dose set by said user.

17. The invention of claim 16 wherein said dose may be increased by turning said dose dial grip in a direction towards said user.

18. The invention of claim 16 wherein said dose may be decreased by turning said dose dial grip in a direction away from said user.

19. The invention of claim 16 wherein during an injection of said set dose, said dose dial sleeve rotates back into said proximal end of said delivery device and rotates in a direction away from said user.

20. The invention of claim 16 wherein during said injection of said set dose, said non-inverted scale is viewable in a window of said housing.

21. The invention of claim 16 wherein said housing further comprises a label, said label comprising text that is viewable by said user in a non-inverted orientation as said user sets said dose of medication.

22. A method of setting a dose for a medical delivery device, said method comprising the steps of

holding said medical delivery device in a right hand of a user,

utilizing a left hand of said user to turn a dose setting member in a direction towards said user to set a dose;

and

providing a non-inverted scale representative of said set dose on said dose setting member representative of said set dose.

23. The invention of claim 22 further comprising the step of

viewing said non-inverted scale as said user sets said dose with said left hand of said user.

24. The invention of claim 22 further comprising the step of

viewing said non-inverted scale as said user injects said dose.

25. The invention of claim 22 further comprising the step of

providing a label on said housing, said label comprising non-inverted text and may be readable by said user as said user sets said dose of medication by turning said dose setting sleeve in a direction towards said user with said left hand of said user.

26. A method of providing a scale on a dose dial sleeve of a drug delivery device, said method comprising the steps of:

determining a maximum dose of said drug delivery device;

determining a minimum dose of said drug delivery device;

determining a scale arrangement that extends from said maximum dose to said minimum dose;

providing said scale arrangement on said dose dial sleeve;

turning said dose dial sleeve in a direction towards said user; and

viewing said scale arrangement in a non-inverted orientation.

27. The invention of claim 26 further comprising the step of providing said minimum dose along a left hand side of said scale arrangement.

28. The invention of claim 26 further comprising the step of providing said maximum dose along a right hand side of said scale arrangement.

29. The method of claim 26 further comprising the step of providing said scale arrangement along a surface of said dose dial sleeve.

30. The method of claim 26 further comprising the step of

providing a label on said drug delivery device so that when said user sets a dose by rotating said dose dial sleeve in a direction towards said user, said label maintains a non-inverted orientation.
