摘要：
Autoinjector The present invention relates to an autoinjector (1) for administering a dose of a liquid medicament (m) which comprises: - a tubular chassis (2) fitable to an elongated chassis (12), - a conducting subassembly comprising a tubular conductor (7) slidably disposed within the chassis (2) and within the housing (12), wherein the conductor (7) is adapted to contain a syringe (3) with an injection needle hollow (4), a thrust spring (8) and a plunger (9) to push the load of the thrust spring (8) to a retainer (6) of the syringe (3), wherein the syringe (3) is lockable for axial translation in conjunction with the conductor (7), - a control spring (19) arranged around the conductor (7), - a needle insertion control mechanism (24) to engage a proximal end of the control spring (19) to the driver (7) to advance the needle insertion or chassis (2), - wherein the The needle (24) comprises a first rim (20) hindered by the control spring in a proximal direction (p), wherein at least a fifth clamp (2.10) is disposed in one of the chassis (2) or the first rim (20). ) initially abutting a block (20.7) on the other between the chassis (2) or the first rim (20), wherein the inclined coupling between the fifth clamp (2.10) and the conductor (7) is provided to deflect the fifth clamp (2.10) in the conductor translation (7) in the proximal direction (p), wherein the external deflection of the fifth clamp (2.10) and the translation of the conductor (7) in the proximal direction (p) are initially prevented by external confinement of the case (12) with the fifth clamp (2.10), wherein the case (12) is at least initially propelled in the distal direction (d), wherein the case (12) is arranged to translate against the proximal thrust ( p) relative to the chassis (2) to an advanced position, thereby translating a second window (12.8) into the case (12) outwardly behind the fifth clamp (2.10), thereby allowing deflection to decouple the fifth clamp (2.10) from the block (20.7) and
