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.

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.

An injection device for administering a liquid is presented that comprises a pre-filled syringe and a safety mechanism for providing needle safety for an injection needle of the pre-filled syringe. The pre-filled syringe comprises a barrel containing the liquid and a stopper translatably disposed within the barrel, where the injection needle attached to a distal end of the barrel. The safety mechanism comprises a substantially cylindrical housing adapted to contain the pre-filled syringe, a plunger connectable to the stopper of the pre-filled syringe and adapted to be translated in a distal direction (D) to expel the liquid through the injection needle, an energizable biasing means arranged between the housing and the pre-filled syringe, wherein the energized biasing means is capable of biasing the pre-filled syringe with respect to the housing in a proximal direction (P) and a retaining mechanism for retaining the pre-filled syringe with respect to the housing in a first retracted position (R1), in an advanced position (A) and in a second retracted position (R2).

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.

Described is a device for intraocular injection comprising a drug delivery device, a foot at a distal end of the drug delivery device for positioning the drug delivery device with respect to an injection site, and a magnifying device coupled to one of the drug delivery device and the foot for magnifying a view of the injection site.
摘要:
A resettable drug delivery device is provided comprising a body, a cartridge holder for receiving a cartridge, and means for releasably coupling the cartridge holder to the body or the dose setting mechanism. During an initial rotational coupling movement of the cartridge holder relative to the body or the dose setting mechanism the cartridge holder is caused to move in a first axial direction relative to the body or the dose setting mechanism and during a continued rotational coupling movement of the cartridge holder relative to the body or the dose setting mechanism the cartridge holder is caused to move in a second, contrary axial direction.
摘要:
A dose setting mechanism for a drug delivery device is provided comprising first maximum dose stop features (1) on a first component part (2) of the drug delivery device and corresponding second maximum dose stop features (3) on a second component part (4) of the drug delivery device, with the first and second maximum dose stop features (1, 3) being designed to limit a relative movement between the first and second component parts (2, 4). To limit the maximum dose which can be chosen, a maximum dose limiting device (5, 10, 10′, 10″, 10″′) is provided interposed on the first component part (2) between the first and second maximum dose stop features (1, 3).
摘要:
A semi-automatic injection device (12) is disclosed containing two reservoirs (6) of medicament, where a trigger (11) controls the unwinding of two torsional springs (18) to cause simultaneous injection of medicament from each reservoir through a needle adaptor configured with a 2 to 1 needle cannula arrangement.
