Abstract: A cap for a fluid line connector having a male luer lock fitting, the cap having a first side and a second side opposite the first side, the cap comprising a barrier and a stopper extending axially from the barrier towards the first side of the cap. The barrier defines a keyway centred on a longitudinal axis. The shape of the keyway is configured to permit a correspondingly-shaped female luer lock fitting to pass axially therethrough to engage the male luer lock fitting of the fluid line connector. The stopper is configured to prevent rotation of the correspondingly-shaped female luer lock fitting in the first circumferential direction when a lug of the correspondingly-shaped female luer lock fitting is circumferentially aligned with the stopper.

Abstract: A one-piece fluid line connector for connecting a fluid feed line to a fluid container includes a main body having a male luer lock fitting, and a cap coupled to the main body by a living hinge. The living hinge is configured such that the cap is moveable to an aligned position in which the cap is aligned with a central axis of the male luer lock fitting of the main body. The cap includes a through-hole configured such that, in the aligned position, the shape of the through-hole permits a correspondingly-shaped female luer lock fitting to pass therethrough and engage the male luer lock fitting.

Abstract: Inside a connector body (112, 114; 300) of a medical connector providing a fluid flow conduit, a one-way valve (118) is fitted directly into one end of a stop valve (116) in a manner providing a fluid tight seal between these valves. The stop valve (116) prevents fluid flowing out of the end (111; 311) of the connector body (112, 114; 300) unless a complementary end of a separate device (not shown), typically a Luer lock connector, engages the end of the connector body and opens the stop valve (116). To facilitate manufacture and assembly, the one-way valve (118) and the stop valve (116) can be formed as parts of a single piece of elastomeric material, the parts being hingedly connected so that the one-way valve part (118) can be folded over to be fitted directly into the end of the stop valve part (116). A further possibility, also applicable when only a stop valve (116) is provided, is that the connector body (300) may be formed in one piece with a folding, snap fit closure (312).

Abstract: To eliminate needle-stick risk by encapsulating the needle of a syringe immediately after discharge of syringe contents, the entire syringe is housed in a device comprising a hollow body, a spring and a plunger. The barrel of the syringe is held in the body interior against the force of the spring by latching formations internal to the body. The plunger is hollow to provide a chamber to receive the syringe piston and at least part of the barrel. The plunger has deflectable engagement elements at its forward end so it is pushed into the body, it reliably displaces the syringe piston/rod to discharge the syringe contents via a hollow needle, the elements ultimately being deflected outwards as the contents are fully discharged so as not to impede syringe retraction into the hollow plunger. The plunger also has latch opening projections at its forward end.

Abstract: A fluid filled cartridge having a fixed needle and a piston assembly for expression of its contents is mounted inside an applicator. In order to extend the needle from the body prior to cartridge contents expression and without premature leakage of fluid therefrom, an actuator is mounted in the body to drive the cartridge forwards. This is accomplished by co-operating driving and driven parts of the actuator and the cartridge (or any carrier it may have) which are decoupled by release formations in the applicator body after the cartridge has been moved sufficiently to extend the needle. The applicator also includes provision for automatic needle retraction after cartridge contents expression. A separate inventive feature is the deformability of the piston so that force transmission to the trigger means to initiate needle retraction only occurs upon full content expression when the piston has “bottomed out” within the cartridge.

Abstract: First and second hollow needles extend from opposing sides of a common hub which is formed in one piece of transparent material. Proximal ends of the respective needles are in communication with each other by a narrow passageway through the hub. The projecting portion of the second needle is covered by an elastomeric sheath. The hub preferably includes a magnifying formation overlying the passageway portion between the proximal ends of the needles. In use, once the point of the first needle penetrates a vein, the patient's blood pressure is sufficient to displace air from the entire first needle and at least part of the passageway through the hub. The sheath over the second needle is sufficiently elastic to allow this and expand accordingly. The blood flows into the piercing needle and the passageway between the needles, thus being viewable through the surrounding transparent material and the magnifying portion, if present.

Abstract: To eliminate needle-stick risk by encapsulating the needle of a syringe immediately after discharge of syringe contents (43), the entire syringe, such as a pre-filled miniature glass syringe (40), is housed in a device comprising a hollow body (10), a spring (20) and a plunger (30). The barrel (41) of the syringe (40) is held in the body interior against the force of the spring (20) by latching formations (IS) internal to the body (10). The plunger (30) itself is hollow so as to provide a chamber (36) to receive the syringe piston means (45, 46) and at least part of the barrel (41) upon retraction of the syringe. The plunger (30) has deflectable engagement elements (33) at its forward end so that as it is pushed in to the body (10), it reliably displaces the syringe piston/rod (45, 46) to discharge the syringe contents (43) via a hollow needle (42), the elements (33) ultimately being deflected outwards as the contents are fully discharged so as not to impede syringe retraction into the hollow plunger (30).
