摘要：
The syringe assembly for use in medication delivery comprises:
- a syringe barrel (12) having a needle (11) at a distal end (122) of the barrel (12);
- a tubular body (2) defining an enclosure, said barrel (12) extending at least partially within said enclosure;
- a safety shield (3) for the needle (11), longitudinally movable with respect to the tubular body (2) between a retracted position and an activated position;
- a spring (4) urging said safety shield (3) towards said activated position;
- a first locking mechanism (31) for locking the safety shield (3) in the retracted position, wherein the first locking mechanism (31) is manually releasable by a user so as to let the safety shield (3) reach the activated position.
- the tubular body (2) including at least one longitudinal slot (21), and the safety shield (3) including at least radial pin (30) engaging the longitudinal slot (21) such that the radial pin (30) moves from a proximal part (211) of the longitudinal slot (12) to a distal part (212) of the longitudinal slot (21) when the safety shield (3) moves from the retracted position towards the activated position;
- the first locking mechanism (31) being configured to hold the radial pin (30) at the proximal part (211) of the longitudinal slot (21).
