    摘要: A syringe assembly, comprising a syringe barrel having a forward end and a rearward end and being arranged along a longitudinal axis; a restricting element, moveably supported onto a portion of the syringe assembly and positionable in one of an injection disabling position and an injection enabling position in different operative orientations of the syringe assembly; a plunger rod assembly displaceable within the syringe barrel and operatively coupled with the restricting element; the plunger rod assembly having a restricting feature adapted to cooperate with the restricting element, such that when the restricting element in the injection disabling position, the plunger rod assembly is permitted to be displaced axially forwardly only up to a certain longitudinal extent relative to the syringe barrel and when the restricting element is in the injection enabling position, the plunger rod assembly is permitted to be further displaced axially forwardly relative to the syringe barrel.

    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.
