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： The invention provides a safe auto-needle device for injection, comprising: a main housing and a syringe-support receiving a disposable prefilled syringe terminating in a needle covered by a needle sheath (NS). The speed of depressing of the syringe plunger is manually controllable by a user. In a first embodiment, a locking mechanism is present, for preventing premature advancement of the needle. A second embodiment comprises an interlock, for preventing depressing of a plunger, prior to advancement of the syringe-support to a needle penetration location. Additional components include a drive mechanism; and a needle shield moveable between: a needle covered position; a partially exposed position, to a fully extended needle safe position. The invention also discloses a needle sheath (NS) remover.
