Injection device with helical or spiral dose scale

摘要

The inducing- and dosing device has a dose display element (10), where a helical dosage scale (10a) is arranged on the periphery of the dose display element. The dosing display element is screwed around a rotary axis relative to a pointing device (4a) by rotating a dosing unit (3) relative to the indicating device for setting the dose to be applied. A value of the dosing scale is read by the pointing device. A bearing element (9) has a threading (9a), which is engaged with the threading (10b) of the dosing display element.
