Autoinjector with a signaling device

An autoinjector for dispensing a liquid product, comprising:

• a housing;
• a product container of a syringe non-slidably arranged in the housing, the product container comprising a displaceable piston for dispensing the product contained in the product container;
• a drive member for displacing the piston during the product dispensing;
• a first spring for displacing the drive member, wherein the first spring is pretensioned such that the first spring can dispense the product from the product container by displacing the drive member and the piston by a dispensing stroke in a dispensing direction;
• a syringe holding means accommodated in an axially fixed manner in the housing for accommodating the syringe in such a way that the syringe is secured against a movement in a distal direction relative to the syringe holding means, the syringe holding means comprising at least one inward projecting engagement element formed elastically as a shoulder adapted to support a tapering section of the syringe which is distal to a cylindrical syringe body that guides the piston, and adapted to be deflected by a needle protective cap of the syringe and snap into a gap between the tapering section of the syringe and a proximal end of the needle protective cap thereby securing the syringe against movement in the distal direction relative to the syringe holding means;
• a holder acting on the cylindrical syringe body by pressing a proximal end of the syringe into engagement with the at least one inward projecting engagement element, wherein the syringe holding means and the holder are configured to act on the syringe body such that the syringe body is non-slidable relative to a longitudinal axis of the housing during dispensing of the liquid product;
• and
• a holding section of the housing to hold the at least one inward projecting engagement element in engagement with the tapering section of the syringe in a force- or form-locking manner.

An autoinjector for dispensing a liquid product, comprising:

• a housing;
• a product container of a syringe arranged in the housing, the product container comprising a displaceable piston for dispensing the product contained in the product container, the syringe comprising a non-detachably connected injection needle covered by a needle protective cap;
• a drive member for displacing the piston during the product dispensing;
• a first spring for displacing the drive member, wherein the first spring is pretensioned such that the first spring can dispense the product from the product container by displacing the drive member and the piston by a dispensing stroke in a dispensing direction;
• a syringe holder for accommodating the syringe in such a way that the syringe is secured against a movement in a distal direction relative to the syringe holder, comprising at least one inward projecting engagement element formed elastically as a shoulder adapted to support a tapering section of the syringe which is distal to a cylindrical syringe body that guides the piston, and adapted to be deflected by the needle protective cap of the syringe and to snap into a gap between the tapering section of the syringe and a proximal end of the needle protective cap thereby securing the syringe against movement in the distal direction relative to the syringe holder;
• a holder acting on the cylindrical syringe body by pressing a proximal end of the syringe into engagement with the at least one inward projecting engagement element;
• a holding section of the housing to hold the at least one inward projecting engagement element in engagement with the tapering section of the syringe in a force- or form-locking manner;
• and
• a needle protective sleeve displaceable relative to the housing in a proximal direction into an actuated position in order to trigger the dispensing of the product.
