Abstract: The invention relates to a needle protection device for a pre-filled syringe with staked needle. This device comprises a blocking mechanism, comprising means for fastening to a syringe body, a needle shield, into which the needle can be driven, and an after-use safety system comprising a sleeve defining a central axis along which it is movable and means for resiliently loading the sleeve in a forward position in which it is able to cover the needle. The sleeve comprises an outer tube and a coaxial inner tube that are manufactured in one piece by injection molding, while the outer tube is arranged so as to cooperate with the blocking mechanism, and the inner tube is detachable from the outer tube and axially connected in translation with the needle shield.

Abstract: An after-use safety system for a syringe, including a barrel which defines a central axis along which it can move in translation and which includes a radial opening forming a guidance path for a pin, an immobiliser, which is arranged inside the barrel and which includes the pin interacting with the barrel, and a return spring configured to elastically load the barrel forwards with respect to the immobiliser, the immobiliser including a radial stopping means for immobilising the barrel along one axis radial to the central axis when the barrel is forced towards the rear after use of the syringe.

Abstract: The device allows the connection between a vessel closed off by a perforable stopper and a container. It comprises a base, which is configured to be mounted on the vessel and which comprises a hollow member for perforating the stopper, this hollow member delimiting at least one opening, and a needle holder, which is waiting to be connected with the container, and which includes a needle, one of the ends of which emerges in the inner volume of the hollow member. The device further comprises a collar attached to a needle holder, and a sheath, which is connected around the collar and which defines a central axis along which it is movable against a resilient force exerted by a spring.

Abstract: The housing for mounting an elongate-shaped container on an injection pen comprises an elongate-shaped body which extends along a longitudinal axis (X30) and which defines an interior volume (V32) for fully receiving the container. The body is provided, on the outside of a first axial end, with at least one first mechanical member for attaching a needle. The body is further provided, in the vicinity of a second axial end opposite the first axial end, with at least one second mechanical member for attaching the housing onto an injection pen. The housing further comprises, in the vicinity of the first axial end thereof, at least one third mechanical member for irreversibly locking a container in position, fully contained in the interior volume (V32) of the body of the housing. Said third locking member is formed by an elastically deformable tab intended to ensure locking of the container in position in the interior volume (V32) of the body of the housing, by axially retaining a flange of the container.

Abstract: A syringe having a bonded needle, comprising a syringe body, a needle protector comprising a flexible cap, an outer sleeve, which can move along a longitudinal axis between an extended position, in which it covers the needle, and a retracted position, in which it does not cover the needle, and a collar, which is mounted with a radial clearance around an end part of the syringe body and which comprises at least one pin engaged in a guide opening of the sleeve. A portion of the flexible cap fills the radial clearance between the end part of the syringe body and the collar when the cap is mounted on the syringe, such that the collar cannot rotate around the end part of the syringe body as long as the cap is mounted on the syringe.

Abstract: The invention relates to a method for producing pre-filled cemented needle syringes, comprising the following steps: a device (D) for protecting the needle onto syringe bodies (2), the device comprising an external sleeve which can move along a longitudinal axis between a forward position in which it covers the needle, and a retracted position in which it does not cover the needle, means for returning the sleeve to the forward position, and a needle protector; arranging the syringe bodies (2), which are provided with the protective device, in recesses (O204) provided in a holder (200); placing the holder (200) in a container (100) for transport; removing the holder from the container; filling each syringe body with an active principle; inserting a plunger into each syringe; and removing the syringes (1) from their holder for the purpose of inspection and labelling.

Abstract: An automatic injector includes a cover extending along a longitudinal axis. A syringe for injecting a drug is arranged inside the cover, and includes a needle, a needle protector, a body, a plunger, and a rod for pushing the plunger into the syringe body, which is moved axially forwards by a resilient load force exerted by a first spring during an injection. The syringe also includes a tip for protecting the needle, which is axially movable about the needle and against a resilient load force exerted by a second spring between a forward position in which the tip surrounds the needle and a retracted position in which the needle is uncovered. A mechanism blocks the forward movement of the rod. The mechanism is deactivated as the tip is moved towards the retracted position and is reactivated during the injection when the tip is moved towards the forward position.
