    摘要: A safe auto-needle device for injection, comprising: a main housing; a syringe-support for receiving a disposable prefilled syringe; said syringe comprises: a piston; a proximal end; and a distal end terminating in a needle covered by a needle sheath (NS); a drive mechanism for advancing said syringe-support distally towards an injection site; a tubular needle shield; moveable from: a needle covering position, to partially exposed, to needle irreversibly concealed; said generally tubular needle shield comprising a distal end for contacting an injection site, and a proximal end; a spring urging distal movement of said needle shield; and said needle shield comprising a spring seat; an NS remover, designed to mate with and irreversibly grip said NS, for removal of said NS prior to injection; a locking mechanism preventing premature advancement of said needle; a plunger rod for engaging said piston, wherein depressing of said plunger is manually controllable; wherein in use of said device, said NS remover is removed; said distal end of said needle shield is pressed upon an injection site, releasing said locking mechanism, and driving said syringe-support and said syringe, distally until needle penetration; and upon depressing of said plunger, a medicament may be injected. The invention additionally provides a novel two-component NS remover.

    摘要: An injection device for injecting a fluid into an object, the injection device including a plunger assembly for operative engagement with a syringe adapted to contain the fluid and permit ejection of the fluid therefrom via a syringe outlet, the plunger assembly being displaceable in a first direction which causes at least some of the fluid contained in the syringe to be ejected from the syringe via the syringe outlet and an inadvertent fluid ejection prevention assembly coupled to the plunger assembly for preventing ejection of fluid from the syringe in situations where the syringe outlet is neither in operative engagement with a vial adaptor suitable for providing fluid communication with the interior of a vial nor in fluid communication with an injection site within the object.
