Abstract

A device for displaying a dosage setting on an injection device includes a reading area in a casing of the injection device and a scale band arranged in the interior of the casing. The scale band is at least partially guided past the reading area by a guiding device, and can be set in accordance with a dosage setting of the injection device, and the dosage setting can be read from the reading area. A transport device, coupled to a dosage setting device of the injection device, is provided for transporting said scale band past the reading area.

Claims

1. A device for displaying a dosage setting of an injectable product on an injection device, comprising a reading area on a casing of the injection device and a scale element arranged at least partially in the interior of the casing, wherein the scale element can be moved in accordance with setting a dosage, and a scale unit of the scale element corresponding to the dosage setting can be read from the reading area, wherein:

the scale element is provided by a scale strip which is at least partially guided past the reading area by a guiding device; and

a transport device for transporting the scale strip is provided adjacent to the reading area and is coupled to a dosage setting device of the injection device.

2. The dosage displaying device as set forth in claim 1, wherein the scale strip is flexible.

3. The dosage displaying device as set forth in claim 1, wherein the scale strip is guided at least partially along the inner circumferential surface of the casing.

4. The dosage displaying device as set forth in claim 1, wherein the scale strip is guided at least partially through the interior of the casing in the form of a loop.

5. The dosage displaying device as set forth in claim 1, wherein the scale strip is a closed band.

6. The dosage displaying device as set forth in claim 1, wherein the scale strip is made of metal or plastic.

7. The dosage displaying device as set forth in claim 1, wherein the transport device is detachably coupled to the dosage setting device of the injection device.

8. The dosage displaying device as set forth in claim 1, wherein the transport device comprises a toothed ring on a rotational button for setting the dosage and a toothed ring on a rotatable transport pin which acts on the scale strip.

9. The dosage displaying device as set forth in claim 8, wherein the transport device further comprises at least one diverting gear.

10. The dosage displaying device as set forth in claim 9, wherein a transfer is provided between the toothed rings.

11. The dosage displaying device as set forth in claim 10, further comprising slaving cams arranged on the circumference of the rotatable transport pin and holes are arranged along the scale strip, wherein at least one of the slaving cams engages with at least one of the holes.

12. The dosage displaying device as set forth in claim 1, wherein a lens is provided in the reading area of the casing.

13. A device for displaying a dosage setting of an injection device comprising:

a reading area associated with the injection device;

a scale band arranged in the injection device generally adjacent to the reading area;

transport means operably coupled to dosage setting means associated with the injection device for setting a dosage, said transport means for transporting said scale band past a portion of the reading area; and

guiding means for at least partially guiding the scale band past the reading area.

14. The device according to claim 13, wherein the scale band is positioned in accordance with a dosage setting of the injection device.

15. The device according to claim 14, wherein the dosage setting can be read from the reading area.
