Abstract: The syringe comprises a body containing the liquid and having fitted thereto an endpiece for fastening a needle carrier. The safety device comprises a protective sheath and a syringe support that is received inside the sheath. The sheath and the support are axially movable relative to each other between two positions, namely a disengaged position of the needle, and a retracted position of said needle. The support includes anti-rotation means for constraining it in rotation about its axis and comprising at least one pawl urged resiliently into a position in which the pawl is designed to co-operate with complementary anti-rotation means of the fastener endpiece. The sheath and the support include complementary anti-rotation means for constraining them in rotation relative to each other about their axes and activated at least when the sheath and the support are in their disengaged position of the needle.

Abstract: The security assembly is designed to be fitted to a syringe comprising a body provided with one end for connection to an injection needle and one end for inserting a piston. The security assembly comprises a member for fitting to the body of the syringe so as to be constrained axially relative to the body, and a security cap for covering the injection end of the body, the cap being provided with a proximal portion for connection to the fitted member and a distal portion for releasing the injection end and connected to the connection portion by frangible means. The fitted member forms a member that is designed to retain the piston inside the body.

Abstract: A sheathed control cable includes an inner cable, a cable-guide duct of a material having a low coefficient of friction surrounding said cable with clearance, armoring surrounding the cable-guide duct, and an outer sheath providing mechanical protection, wherein the cable-guide duct is a duct of microporous PTFE obtained by lubricated extrusion and that has been subjected, on leaving the extruder die, to simultaneous drawing and heating to a temperature above the sintering temperature of PTFE.
