Abstract
An injection device has a housing ( ) and therein a spring for storing energy for an injection operation. The spring ( ) impinges, in the proximal direction, upon an ejection member ( ) for ejecting injection liquid ( ) from a vessel, displaceably arranged in the housing, at whose proximal end an injection needle is attached. Located in the housing is a displacement member ( ), displaceable in the longitudinal direction, for displacing the vessel ( ) in the proximal direction, in order to effect a movement of the injection needle ( ) in the proximal direction and, thus, its insertion. Provided on the ejection member ( ) is a detent lug ( ), associated with which is a corresponding detent opening ( ) in the displacement member ( ). A control member ( ), effective in travel-dependent fashion, serves to disengage the detent lug ( ) from the detent opening ( ) when the displacement member ( ), during the injection operation, has traveled a predefined distance in the proximal direction.
