摘要： According to the invention, a safety device for a pre-filled syringe comprises a hollow support body to retain the pre-filled syringe therein, a hollow needle shield that is slidable relative to the support body and guiding means for guiding the movement of the needle shield relative to the support body. The guiding means comprise a guide pin, a guide track and a cut-out adjacent to the guide track. The guide pin protrudes into the guide track and moves within and along the guide track when the needle shield is slid relative to the support body. The cut-out allows a side wall of the guide track to be deflected in a lateral direction perpendicular to a central axis of the safety device.

摘要： An injection device comprises a pre-filled syringe and a safety mechanism for providing needle safety for an injection needle of the syringe. The syringe comprises a barrel containing the liquid and a stopper disposed within the barrel. The needle is attached to a distal end of the barrel. The safety mechanism comprises a substantially cylindrical housing adapted to contain the syringe, a plunger to expel the liquid through the injection needle, and an energizable biasing member arranged between the housing and the syringe. The energized biasing member is capable of biasing the syringe with respect to the housing in a proximal direction and a retaining mechanism for retaining the syringe with respect to the housing in a first retracted position in an advanced position and in a second retracted position.

摘要： A safety device suitable for a pre-filled syringe containing a medicament includes a chassis adapted to be affixed to the pre-filled syringe, a deformable flexible outer structure made from a material with a shape memory, and a substantially cylindrical needle shield affixed or integral to the outer structure. The deformed flexible outer structure is capable of advancing the needle shield with respect to the chassis in a distal direction into a position in which the needle shield projects from the chassis in the distal direction. A biasing force for advancing the needle shield originates from a shape memory effect that causes the deformed flexible outer structure to substantially return to its unstressed shape.

摘要： According to the invention, a safety device for a pre-filled syringe comprises of a needle shield adapted to cover an injection needle of the pre-filled syringe before and after an injection, a support body with at least one pivoting arm adapted to engage a barrel collar of the pre-filled syringe and an outer body with a first inner sleeve comprising a bevelled section. The needle shield, the support body and the outer body are telescopically arranged. The needle shield, the support body and the outer body may telescope with respect to each other to cover and to expose the injection needle of the pre-filled syringe. The bevelled section is arranged to abut against the pivoting arm connected to the support body by a living hinge to deflect the pivoting arm radially inwards, so that the pivoting arm may engage the barrel collar after a dose of a medicament contained in the pre-filled syringe has been disposed beneath the skin of a patient receiving the injection.
