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 pre-slit injection site includes a housing with a flow path therethrough. A first end of the housing carries a pre-slit septum. One form of a blunt cannula, usable with the injection site, carries a locking member. When the pre-slit injection site slidably receives the blunt cannula, the locking member latches to the injection site and creates a mechanically coupled unit. Another form of the cannula includes a tube having a tapered distal end region and having elongate discharge slots for reducing contact surface area and for directing the flow laterally out of the cannula. The cannula may also include a rounded lead post, an annular barb, and axially oriented grooves.

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 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.

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.
