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.

A safety device for a pre-filled syringe is proposed that comprises a hollow support body with a helical groove formed into an inner surface thereof, a mounting collar for mounting the pre-filled syringe to the support body, a spinning collar with a helical tongue formed to an outer surface thereof and a torsion spring. The helical groove accommodates the helical tongue. Upon release, the torsion spring is capable of exerting a torque upon the spinning collar which causes the spinning collar to rotate within the support body. The engagement of the helical groove and the helical tongue redirects the rotational movement of the spinning collar to a translatory movement that moves the mounting collar in a proximal direction.

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.

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.

A cylinder head for an engine is provided comprising a monolithic structure forming an upper deck, a fire deck, at least one coolant jacket and a cavity to accommodate a fuel injector or an ignitor therein, the cavity defined by a wall connecting the fire deck with the upper deck. The wall connecting the fire deck with the upper deck, as well as other features of the cylinder head, are preferably arranged to support the fire deck against a deflection thereof by transmitting a mechanical load introduced on a flame face of the fire deck to the upper deck. A method of increasing the stiffness of the cylinder head is also provided.

A method and system of monitoring an object (e.g., for change in configuration of a person) includes projecting a radiation pattern onto the object; recording at a first time first image data representing a portion of the projected radiation pattern on the object, the first image data representative of a three dimensional configuration of the object at the first time; recording at a second time second image data representing a portion of the projected pattern of radiation on the object, the second image data representative of a three dimensional configuration of the object at the second time; and processing the first and second image data to generate differential data representative of a change in the configuration of the object between the first and second times.

According to the invention, a safety device for a pre-filled syringe comprises a hollow support body having a releasable mounting means adapted to mount a pre-filled syringe within the support body, a hollow outer body sildably arranged with respect to the support body and adapted to receive the support body and a release collar non-rotatably arranged within the support body. The release collar is movable relative to the support body and adapted to release the mounting means. A guide track is formed into at least one substantially planar side wall of the support body. The release collar comprises at least one flexible arm with a guide pin that extends from the flexible arm and protrudes through the guide track. The guide pin is movable within and along the guide track in a plane defined by the substantially planar side wall. A guide rail is formed into at least one substantially planar inner surface of the outer body. The guide rail is adapted to abut against the guide pin to guide the movement of the guide pin along the guide track when the outer body is slid relative to the support body.

A safety device for a pre-filled syringe comprises a hollow support body to retain the pre-filled syringe, a retaining collar and a rotating collar arranged within the support body. The retaining collar is releasably mounted to the support body. The rotating collar is slidable along an axial length of the support body and rotatable around a central axis of the safety device. The retaining collar is movable with respect to the support body in a proximal direction when the retaining collar is released from being mounted to the support body by the rotating collar.
