Abstract

A dynamic identification system for a multi-dose injection device includes a dose dial sleeve containing indicia of the medicament contained within the device becomes visible or available to the olfactory or gustation senses only during dose setting as the dial sleeve is translated proximally out of the outer housing of the device. A user can readily identify the medicament contained within the device as the dose is being set. A static identifier located on the device that matches the dynamic identifier on the dial sleeve can also be used as a medicament identifier.

Claims

1. A dose setting mechanism for a drug delivery device, the mechanism comprising:

an outer body;

an inner body having a helical groove along an external surface of the inner body; and

a dial sleeve that is disposed between the outer body and the inner body, where the dial sleeve has an inner surface that is,

rotatably engaged with the helical groove of the inner body; and

contains an indicia on the outer surface to identify a medicament in the drug delivery device, where the indicia is hidden from view when a zero dose is set, wherein when a dose is set, the dial sleeve is rotated with respect to both the outer body and the inner body causing the dial sleeve to translate away from the outer housing exposing the indicia on the outer surface of the dial sleeve.

2. The dose setting mechanism of claim 1 wherein the indicia is selected from the group consisting of text, numbers, labels, tags, geometric designs, Braille figures, colors, tactile shapes and combinations of these.

3. The dose setting mechanism of claim 1 wherein the outer surface of the dial sleeve is pigmented to allow a user of the drug delivery device to visually identify and distinguish the device as containing a specific type of medicament during setting of a dose.

4. The dose setting mechanism of claim 1 wherein said dial sleeve has a generally smooth outer surface and contains printed letters, numbers, color, geometric designs or a combination of these indicia forms.

5. The dose setting mechanism of claim 1 wherein the outer surface of the dial sleeve is textured to allow a user of the drug delivery device to tactilely identify and distinguish the device as containing a specific type of medicament.

6. The dose setting mechanism of claim 1 where the dial sleeve comprises two or more sections that are connected together during assembly so that the connected sections move together in unison.

7. The dose setting mechanism of claim 6 where a first section of the dial sleeve provides a surface onto which the dose numbers are printed and a second section is pigmented to provide the required indication of drug type.

8. A method of providing a dynamic indicia of medication to a drug delivery device comprising adding a scent, flavor or a combination of scent and flavor to a dose setting member or dose delivery member of an injection device accessible to the user before dose delivery.

9. A dose setting mechanism for a drug delivery device, the mechanism comprising:

a body; and

a dial sleeve that is operably connected with the body, where the dial sleeve has an outer surface that contains an indicia to identify a medicament and where the indicia is hidden from view when a zero dose is set;

wherein at least part of the indicia on the outer surface of the dial sleeve is exposed when a dose greater than zero is set.
