A catheter assembly (10) comprises a catheter (22), a needle (12) having a sharp distal tip, a catheter hub (14) housing the catheter (22), the catheter hub (14) having a collar (34) including a notch (36), a needle shield (20) connected to the catheter hub (14) when the needle (12) is in a first position, and a clip (40) disposed in the needle shield (20) that cooperates with the needle (12), wherein the clip (40) engages the catheter hub (14) in the first position of the needle (12), and the clip (40) disengages the catheter hub (14) via the notch (36) when the needle (12) is retracted to a second position to cover at least a portion of the needle (12). The clip (40) is mounted in the outer housing (38) of the needle shield (20) via a spade (66) having an outer wall (70) exposed to the outside of the needle shield (20), in order to reduce the overall width of the needle shield (20).

A needle tip (22) for being connected and disconnected in use from a needle tip support (16), comprises a needle (24) having a forward end and a rearward end and, a connector secured to the needle intermediate its ends. The connector comprises two arms (28) each extending outwardly and rearwardly relative to the needle (16) and configured to be coupled and uncoupled in use from said needle tip support, and the arms are disposed on opposite sides of the needle. Also disclosed are arrangements for storing, dispensing and later disposing such needle tips, as well as coupling interfaces between the needle tip and a needle support cap to which it is fitted in use.

Medical devices such as medical containers can be formed of glass and annealed which produces a clean device having a low bio-burden, or formed by plastic molding which produces a clean device. The clean devices are immediately transferred to a controlled environment such as a clean room or localized area to avoid the need to maintain cleanliness levels in an entire room. Syringe tip closures can be introduced into the housing assembly, where syringe barrels and tip closures are cleaned with filtered ionized air and the tip closures are coupled to the barrels. The syringe barrels can be filled with a substance and a closure member attached. While still in the housing assembly the syringe barrels can be formed into an array and placed in a clean outer container, which is then closed and sealed.

A connector assembly for a fluid delivery system includes a conical body defining an interior cavity and a discharge outlet, the discharge outlet defining an internal passage in fluid communication with the interior cavity; and a connector removably attached to the discharge outlet. The connector includes a central body configured to be at least partially positioned within the internal passage of the discharge outlet, and an annular connector portion connected to the central body and configured to releasably engage an exterior of the discharge outlet, the central body defining an internal channel within the central body that is in fluid communication with the interior cavity of the conical body when the connector is attached to the discharge outlet.

A syringe is provided, including a syringe barrel, a needle set and a push rod. A front end part is provided in the syringe barrel. An end of the needle set has an open area, the open area is transversely provided with a first snap part. The push rod is slidably disposed within the syringe barrel, and an end of the push rod facing the front end part has a second snap part. When the push rod is slidingly moved to the front end part, the second snap part is engaged with the first snap part.

A low deadspace syringe having a pivoting protective needle guard on a fixed needle assembly that is permanently attached to the syringe.

A magazine assembly (1) that stores a plurality of needles (56) configured to engage a medication pen (2) via an adapter (4) for medication delivery, the magazine assembly (1) comprising a magazine housing (20) enclosing a plurality of hub chambers (22) each enclosing one of a plurality of needle hubs (50), a connector (28) in each of the plurality of hub chambers (22), each connector (28) engages one of the plurality of needle hubs (50), and a plurality of enclosures (30) each sealing the plurality of hub chambers (22), wherein a selected enclosure of the plurality of enclosures (30) is removed to expose a selected needle hub (52) of the plurality of needle hubs (50), the adapter (4) attaches to the medication pen (2) to engage the selected needle hub (52) while disengaging the selected needle hub (52) from the hub chamber (22), and the selected needle hub (52) is removed from the magazine housing (20) to prepare the medication pen (2) for medication delivery.

A syringe includes a syringe barrel defining a needle receiving chamber and a plunger receiving chamber, a pull-back member received in the needle receiving chamber, and a plunger received in the plunger receiving chamber and comprising an end defining a first receiving chamber and a second receiving chamber. The pull-back member is configured to mount a needle thereto and comprising an engagement portion. The first receiving chamber has a sectional area that is less than a sectional area of the second receiving chamber, and the first receiving chamber has a closed curved surface. The engagement portion is configured to pass through the first receiving chamber and snap-fit into the second receiving chamber when the plunger is inserted into the pull-back member.

A needle actuator assembly for a drug delivery system includes a needle actuator body having a guide surface, a needle shuttle having a cam surface, with the needle shuttle moveable along a vertical axis between a first position and a second position. The needle shuttle is configured to move between the first and second position through engagement between the guide surface of the needle actuator body and the cam surface of the needle shuttle. The assembly further including a needle received by the needle shuttle.
