Abstract
A prefilled ready-to-use syringe, including a tubular body having, at its distal end, a tip to take a needle and, at its proximal end, a flange, a piston able to slide inside the tubular body and defining, with the tubular body, an internal working volume at least partially filled with a liquid, a rod for actuating the piston extending beyond the proximal end of the tubular body, characterized in that a rigid cover is attached and fixed in a definitive way to the flange and has a central opening for the free translational passage of the actuating rod, and the said cover forms a stop for the actuating rod in the proximal direction, and a plug is arranged to translate freely in the tubular body between the piston and the proximal end of the body, the plug being resistant to puncturing with a needle.
