An injection device provides a casing which accommodates or forms a reservoir for a liquid drug; a plunger rod which can move relative to the casing in an axially forward direction to deliver the drug; a dosing means which can move in the forward direction relative to the casing to prime the reservoir and which can rotate relative to the casing for selecting a dose to be injected, wherein rotation of the dosing means relative to the casing is prevented until a priming operation for priming the reservoir is completed; d) wherein the dosing means comprises a dosing control means which is configured to enable rotation of the dosing means at the end of the priming stroke for selecting the dose and to prevent a rotation of the dosing means back into the position which the dosing means had at the end of the priming stroke relative to the casing.

Injection device with dosing control means

An injection device provides a casing which accommodates or forms a reservoir for a liquid drug; a plunger rod which can move relative to the casing in an axially forward direction to deliver the drug; and a dosing means which can move in the forward direction relative to the casing to prime the reservoir and which can rotate relative to the casing for selecting a dose to be injected. Rotation of the dosing means relative to the casing is prevented until a priming operation for priming the reservoir is completed. The dosing means comprises a dosing control means which is configured to enable rotation of the dosing means at the end of the priming stroke for selecting the dose and to prevent a rotation of the dosing means back into the position which the dosing means had at the end of the priming stroke relative to the casing.
