摘要：
A method for determining an injection process of an injection appliance includes injecting a fluid with the injection appliance and applying an electrical signal to at least one helical spring of the injection appliance coupled to a dosing wheel of the injection appliance. The method also comprises detecting an inductance value of the at least one helical spring. A number of windings of the at least one helical spring is dependent on a set rotation angle of the dosing wheel. The set rotation angle corresponds to a dose quantity of the fluid that is preselected for the injection process. The method moreover includes making available a determination signal representing the determined injection process, using the detected inductance value.
