摘要：
The invention relates to an injection supporting device (1) for a syringe (5). The syringe (5) comprises a cartridge (51) for a medicament and may comprise an injection needle (6) extending in a z-direction from the cartridge (51) to dispense the contents of the cartridge (51). Alternatively the injection needle (6) may be part of the injection supporting device (1) itself. The injection supporting device (1) comprises a housing (2) to receive at least a part of the cartridge (51), a needle shield (3) and a resilient member coupled to the needle shield (3) and the housing (2). The needle shield (3) comprises a distal portion (31) and a proximal portion (33), a distal opening (311) in a front end of the distal portion (31) and a needle guide for guiding the injection needle (6) towards the distal opening (311). The needle shield (3) is slidably attached to the housing (2) and slidable relative to the housing (2) along the z-direction between a guarding position covering a tip (61) of the injection needle (6) and an injection position in which a front end portion (62) of the injection needle (6) extends through the distal opening (311) of the needle shield (3). The resilient member urges the needle shield (3) towards the guarding position.
