ABSTRACT:
A needle-protection device (2) for a syringe (1) having a needle (6), a tubular body (4) and an injection plunger (8). The device includes: a needle protector (22); a protector support (20); a spring (24) which presses against the support (20) and the protector (22), the support and protector being movable relative to one another between a retracted protector position, in which the needle of the syringe is exposed and the spring is locked in compression, and a deployed protector position in which the needle is disposed inside the protector and the spring is at least partially decompressed; and a mechanism for unlocking the spring. When locked, the spring (24) exhibits a predetermined force which is greater than the push force required to move the plunger (8) along essentially all of the injection stroke thereof. The mechanism has a digital support flange (50) which (i) transmits to the spring a compression force, which is less than the predetermined force, as the plunger slides along the injection stroke, and (ii) transmits to the spring a compression force, which is greater than the predetermined force, when the plunger reaches the end of the injection stroke.
