Syringe with a handle that can be fitted to a barrel

Abstract

A syringe with an arc-shaped plunger handle that can be fitted both inside and outside the barrel. This ensures that the plunger is pushed straight, and, combined with the hinged plunger head, allows the handle to be folded outwards from the barrel, minimizing its volume. A rotating cap attached to the handle covers the dispensing end of the syringe, sealing the tip.
