摘要： According to the invention a safety device for a pre-filled syringe comprises a substantially cylindrical and hollow support body and a hollow needle shield slideably arranged relative to the support body. The support body comprises at least one resilient arm and the hollow needle shield or a needle shield assembly comprises at least one curved actuation ramp. The curved actuation ramp protrudes in a lateral direction (L) perpendicular to a central axis (A) of the safety device. The curved actuation ramp comprises a first lateral dimension (L1) at a proximal end of the needle shield and a second lateral dimension (L2) exceeding the first lateral dimension (L1) at a distal end of the needle shield. The resilient arm engages the curved actuation ramp when the needle shield is slid relative to the support body.

摘要： According to the invention, an injection device (D) comprises a pre-filled syringe and a safety device. The pre-filled syringe comprises a barrel with an inner cavity in fluid communication with a hypodermic needle attached to a distal end of the pre-filled syringe and a piston fluid-tightly sealing a proximal end of the inner cavity. The safety device comprises a support body for retaining the pre-filled syringe therein, an outer body operably connected to the piston, a needle shield and a releasable retaining means (R). The retaining means comprises a radial projection and a longitudinal recess adapted to receive the radial projection. The radial projection is connected to or integral part of one of the support body or the outer body and a longitudinal recess formed into the other of the support body or the outer body. The needle shield, the support body and the outer body are telescopable relative to each other. The piston is movable in a distal direction to expel a medicament contained in the inner cavity through the hypodermic needle by a manual actuation of the outer body. A telescoping movement of the outer body with respect to the support body is restricted by the retaining means (R) when the needle shield is moved with respect to the support body in a proximal direction from an initial position (I) towards a retracted position (II). The retaining means (R) is released when the needle shield reaches the retracted position (II) allowing for a telescoping movement of the outer body with respect to the support body to expel the medicament contained in the pre-filled syringe through the hypodermic needle.

摘要： According to the invention, a safety device for a pre-filled syringe comprises a hollow support body for mounting 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 flexible arm with a guide pin, a guide track and a separating wall. The guide pin extends from the flexible arm in a radial direction, and protrudes into the guide track. The separating wall extends into the guide track in a direction parallel to a central axis of the safety device. When the needle shield is slid relative to the support body the guide pin moves along the guide track to deflect the flexible arm in a lateral direction perpendicular to the central axis and the movement of the guide pin along the guide track is guided by the interplay of the flexible arm and the separating wall.

摘要： According to the invention, a safety device for a pre-filled syringe comprises a hollow support body for retaining the pre-filled syringe, a hollow needle shield that is movable relative to the support body from a first position to a second position, releasable mounting means to mount the pre-filled syringe within the support body and a spring means arranged within the support body in a non-energized or only slightly energized state. The movement of the needle shield from the first position to the second position fully energizes the spring means.

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.
