Patent ID: 8529507

Claim:
A combination of a cannula protector for covering a cannula attached to a syringe and the syringe, the combination comprising: a single tubular sleeve for axially moveable accommodation of the syringe having a syringe cylinder with a base at one of its ends, the base having an opening for the passage of a cannula; a spring element formed on another end of the sleeve, the spring element which, by application of a compression force against an elastic resetting force that is intrinsic to the spring element, can be compressed axially by a predetermined compression length, and which automatically resets when the compression force is removed, wherein a free end of the spring element abuts against a stop ring of the syringe cylinder of the syringe, when it is moved into the sleeve, in order to move the cannula outwards through the opening; wherein the spring element is a bellows, and wherein at least one radially acting clamp spring is arranged on the sleeve, in order to push, as a result of a radially applied force, against the syringe which is moveable in the sleeve, and to clamp it, and wherein the cannula protector is divided into two in the axial direction and the cannula protector can be assembled by means of an engagement mechanism, after the syringe has been inserted.
