Abstract

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.
