A needle guard for a syringe, includes a base portion having a syringe connection for connecting a syringe and a cover portion and a base portion. The base portion and cover portion are engaged to expose the needle in a use position for administering the syringe to a patient, and after use, the cover portion is configured to slide on the base portion to an extended position on the base portion to cover the otherwise exposed point of the needle in a deployed position. A spring is arranged between the base portion and the cover portion to urge the cover portion to the deployed position on the base portion. An engagement arrangement between the base portion and the cover portion latches the base portion and the cover portion in the use position, and after use, in the deployed position.

The invention relates to an injection device comprising an elongate housing and a cap removably mounted over a forward end of the housing. The cap comprising at least one slot extending forwardly from its rear edge; the at least one slot being configured to engage with an outwardly projecting protrusion on an outer surface of the housing when the cap is mounted on the housing. A rearward portion of the cap includes rearwardly extending engagement features provided on each side of the at least one slot, the engagement features being configured to locate within a cavity in the housing when the cap is mounted on the housing. The cavity is provided with corresponding surfaces which align with the cap engagement features so as to hold the outwardly projecting protrusion within the cut-out.

An autoinjector device is disclosed which comprises a body portion and a syringe carrier, for supporting a syringe with a needle at its forward end. The syringe carrier is moveably mounted within the housing such that forward movement relative to the housing may extend the needle from a forward end of the body. The syringe carrier has a latch element arranged to cooperate with a corresponding retention feature of the body portion to releasably hold the syringe carrier in a rearward position within the body potion. A delivery mechanism is arranged to forwardly displace the syringe carrier relative to the housing and to deliver a dose of medicament from the syringe. A shroud assembly is provided at a forward end of the device. The shroud further comprises a locking arrangement which blocks releasing movement of the latch element from the retention feature when the shroud is in a first, forward position and is unlocked when the shroud is in a second, rearward position.

A fluid injection device including a syringe with a body (1), a piston (3), and a needle (2) with an injection tip (20); a piston rod (5); and a sleeve (10) around the syringe and axially movable between a non-projecting position in which said sleeve (10) does not cover the injection tip (20) and a projecting position. The sleeve (10) urged, while in said non-projecting position, towards its projecting position by a spring (30). The sleeve (10) has an inner portion (11) extending inside the body, and an outer portion (12) extending outside the body (1), the inner portion (11) including a radially-deformable tab (110) snap-fastened in a window (6) of the body (1), blocking the sleeve in its non-projecting position. A hollow member (40) co-operates, after injection, with the radially-deformable tab (110), so that after the fluid is injected, the sleeve is moved automatically towards its projecting position.

A safety needle assembly, including a hub; a needle fixed to the hub, the needle having a distal end and a proximal end; first and second shields, each having a tubular body at least partially encircling a portion of the needle, wherein in an initial state, the first shield extends from the hub; a biasing element disposed to urge the second shield distally toward the distal end of the needle; and a releasable retaining arrangement for releasably retaining the second shield in a first state. Upon a predetermined extent of proximal movement of the first shield relative to the hub, the second shield is released, thereby allowing the biasing element to urge the second shield to a second state in which the distal end of the needle is covered.

A safety needle assembly is provided herein which includes a hub; a needle fixed to the hub; a first shield having a tubular body at least partially encircling a portion of the needle, wherein in an initial state, the first shield extends from the hub; a second shield having a tubular body at least partially encircling a portion of the needle; a biasing element disposed to urge the second shield distally towards a distal end of the needle; and, a releasable retaining arrangement for releasably retaining the second shield in a first state. Upon a predetermined extent of proximal movement of the first shield relative to the hub, the second shield is released to a second state in which the distal end of the needle is covered. Advantageously, two shields are provided for at least partially covering a needle with one of the shields acting as a trigger.

A syringe (1B) comprises: a syringe body (1C) including a plunger (32) to be operated for injection of a drug solution; a cylindrical needle cover (11B) housing an injection needle (100A); and a spring (18) held in a compressed state by the needle cover (11B). The needle cover (11B) has seats (153A) and (155B) in a pair that abut on corresponding opposite ends of the spring (18) to restrict the position of the spring (18). Pushing in the plunger (32) further after injection deforms the seat (155A) to release restriction on the spring (18). The spring (18) free from the restriction abuts on the syringe body (1C). This biases the needle cover (11B) to move the needle cover (11B) to a position where the injection needle (100A) is housed.

A drug injection device (10) including a housing (12) for holding a container (20) having a needle (24) for penetrating skin and a plunger (42) for expelling a drug stored in the container. The device includes visual and/or audible indicators for indicating that the correct depth of needle penetration has been achieved and that drug injection/extrusion has been started and/or completed. The device may further include a label (140) for visually confirming the quality of the drug contained therein. Alternatively, a tray (110) may be provided for receiving the drug injection device, which allows the quality of the drug contained therein to be visually confirmed.

A safety mechanism for a drug delivery device for dispensing a liquid drug from a reservoir through a needle includes a housing defining a longitudinal axis, a needle cover movable along the longitudinal axis between a needle covering position and a retracted position, a movable lock element with a locking position to prevent the needle cover from being moved out of the needle covering position, and a trigger member movable along the longitudinal axis relative to the housing. The trigger member is operatively coupled to the lock element and a movement of the trigger member along the longitudinal axis causes the lock element to move out of the locking position allowing the needle cover to be moved out of the needle covering position.
