Abstract
The disclosure further relates to an autoinjector and a method of assembling the autoinjector. A syringe carrier is disclosed comprising a housing adapted to receive a syringe. They syringe includes a needle encapsulated by a removable protective needle sheath. The syringe carrier further includes two or more flexible arms protruding outwards in a relaxed state and adapted to couple with the syringe in a mounted position. In the mounted position, the flexible arms deflect radially inwards due, in part, to an axial force operating on the syringe carrier.

An autoinjector comprising:
- a syringe carrier comprising
- a housing adapted to receive a syringe having a needle encapsulated by a distal removable protective needle sheath, and
- two or more flexible arms adapted to couple with the syringe in a mounted position;
- and
- a case adapted to receive the syringe carrier.
Method of assembling an autoinjector, the method comprising:
- inserting and pre-positioning a syringe axially into a syringe carrier mounted in a case, the syringe having a needle encapsulated by a removable protective needle sheath;
- inserting a front-assembly tool at a distal end of the case and a back-assembly tool at a proximal end of the case;
- and
- mounting the syringe into the syringe carrier by releasing the syringe carrier from the case using the back-assembly tool and moving the syringe carrier forward within the case using the back-assembly tool.
