INJECTION DEVICE WITH DOSE INDICATOR AND SPRING DRIVE

摘要

A driving and dosing device for an injection device for administering a liquid product, in particular a medication, wherein a product dose to be administered can be set by means of the driving and dosing device, comprising: a) a housing, b) a dose indicating element, around the circumference of which a dose scale is arranged, c) a pointing device and a (d) dosing element that can be gripped in particular by the user of the driving and dosing device, wherein the dose indicating element can be rotated, in particular screwed, relative to the pointing device and about an axis of rotation (L) and a value of the dose scale that corresponds to the set dose can be read by means of the pointing device, in order to set the dose to be administered by rotating the dosing element relative to the pointing device, and e); a discharge spring, which stores the energy required for discharging the product, wherein the discharge spring is loaded by means of rotation of the dosing element.
