An apparatus for destroying syringes-needle assemblies is disclosed, the invention comprising a cradle for holding the syringe and a hub grip for gripping the hub of a needle affixed to the syringe. The apparatus comprises means for destroying the needle for example, by passing a current through it to soften/melt it, whilst at the same time, applying an axial compressive force to blunt and compress the needle. The hub grip is moveable relative to the cradle so that the needle can be pulled, unscrewed or otherwise detached from the syringe. The apparatus is preferably automated, and thus enables the destroyed needle and syringe to be separated, and therefore disposed of in separate waste streams without manual intervention.

The injection needle removal device has: a cylindrical outer cylinder on an upper opening of an injection needle case; a helical track on an inner peripheral surface of the outer cylinder in a helical shape from an upper locking point to a lower locking point; a syringe holding cylinder helically advances in the outer cylinder along the helical track; an injection needle tightening ring on a lower end portion of the syringe holding cylinder, the injection needle tightening ring holds an injection needle base portion of a syringe in the syringe holding cylinder to clamp the injection needle base portion; and a locking mechanism that stops the syringe holding cylinder where the injection needle tightening ring is exposed from a lower side of the outer cylinder at the lower locking point. The injection needle tightening ring turns to remove the syringe needle base portion from the syringe body and to expand in a distal-end divided manner by a turning generated by a descending movement of the syringe holding cylinder proximate the lower locking point to discard the injection needle base portion into the injection needle accommodation case with the injection needle.

A casing is described for shielding a hypodermic needle. The casing has a protective rigid housing comprised of a first open end, rigid side walls and a second closed end distal from the first open end.
