Abstract: An injection site usable with a blunt cannula, comprises an injection site (812) having a pre-slit sealing member, the injection site being integrally formed with a spike connector (814) for insertion through the stopper of a vial, for connecting a cannula, through the injection site and spike connector, with the vial. The spike connector has a barb (818) which holds the connector in place in the vial and preferably has a solid centre point.

Abstract: A protective shield for a blood sampling unit that is movably engaged to an adapter having a needle attached. The shield attaches to a tube holder when the needle is covered by the shield. Longitudinal grooves on the adapter guide the shield between a first position, covering the needle, and a second, position, exposing the needle. The shield can be locked in either the first position or the second position. The blood sampling unit is safely disassembled or reassembled when the needle is covered by the shield. In an embodiment of the invention, a tip protector, removably attached to the adapter, extends through the length of the tube holder to prevent needlesticks. The blood sampling unit and the tube holder can be assembled and disassembled when the tip protector is attached to the adapter, covering the needle. The tip protector is removed during a clinical procedure and then replaced after the clinical procedure is finished.

Abstract: A cannula (82) and injection site (36) coupling system comprising a cannula assembly having a blunt cannula or piercing member (98) partially surrounded by a protective shield (80). The protective shield (80) is spaced apart from theblunt cannula (98) and includes a bayonet arm (170), a bayonet barb (172), bay-onet lock (174) and an opening or gap (176). The injection site (36) has a septum (52) with a pre-slit opening (66) and an arm (76). When the cannula assembly (82) and injection site (36) are coupled, the injection site arm (76) is lodged with-in the cannula assembly lock (174).

Abstract: A pre-slit injection site (436) includes a housing with an axial flow path (444) therethrough. A first end portion (438) has the form of a male Luer connector. The other end includes a pre-slit septum (442). The tapered exterior surface of the male Luer is substantially surrounded by a generally cylindrical gripping collar (446). The second end is provided on its outer surface with threads (452) and also with a radially-extending shoulder (454). These two distinct locking means allow connection with blunt cannula devices having either an interiorly threaded sleeve (476) or resilient gripping fingers (460).

Abstract: A blunt-ended cannula insertion member (318,324) comprises a tubular member having a cylindrical region (318) and a frusto-conical portion (328) between the blunt end and the cylindrical portion. The blunt end is convex and radial apertures, spaced from the end, open from a fluid flow path in the tubular member. Longitudinal slots (338) are spaced around the tubular member, each open to a respective aperture and each having end openings at the distal end of the tapered portion.

Abstract: A cannula assembly adapted to pierce a solid or unslit closure is disclosed and includes a blunt cannula and a piercing member held in cooperation with or contained within the flow channel of the cannula. Generally, the piercing member includes a tip capable of piercing an unslit stopper or closure and a means to temporarily retain the piercing member from the cannula and prevent inadvertent disengagement of the piercing member from the blunt cannula.
