Abstract
The invention relates to an injection supporting device for a syringe. The syringe comprises a cartridge for a medicament and may comprise an injection needle extending in a z-direction from the cartridge to dispense the contents of the cartridge. Alternatively the injection needle may be part of the injection supporting device itself. The injection supporting device comprises a housing to receive at least a part of the cartridge, a needle shield and a resilient member coupled to the needle shield and the housing. The needle shield comprises a distal portion and a proximal portion, a distal opening in a front end of the distal portion and a needle guide for guiding the injection needle towards the distal opening. The needle shield is slidably attached to the housing and slidable relative to the housing along the z-direction between a guarding position covering a tip of the injection needle and an injection position in which a front end portion of the injection needle extends through the distal opening of the needle shield. The resilient member urges the needle shield towards the guarding position.
