Abstract
Injection device ( ) for injecting fluid from a fluid container ( ) equipped with a piston ( ), comprising an actuating device ( ) having a rod-shaped driven member ( ) having a structured surface, a control button ( ) being movable in axial direction, and a hollow cylindrical counter component ( ) having a structured internal sleeve and said counter component matching the rod-shaped driven member ( ). When twisting the counter component ( ) in relation to the driven member ( ), the driven member ( ) can be shifted freely in axial direction. This allows the free return of the driving member—without the need for additional control elements—only when the patient releases the driven member ( ) by turning it, i.e. by a conscious additional operation.
