Abstract: A connector (10) is provided which utilizes a resealable pre-slit septum valve (28). Septum (28) is resiliently restrained relative to housing (26) with septum (28), and housing (26) configured to accept a standard male luer lock (13) having luer tip (18) which penetrates septum (28) through resealable opening (44) to extend within housing (26), and luer locking flange (20) of luer lock (13) extending about housing (26). The septum (28) includes disk shaped upper portion (38) covering opening (44), lower portion (40) spaced from housing (26) and extending downward from disk shaped portion (38) into passageway (36) defined by housing (26), and annular skirt (52) to attach septum (28) to housing (26). Connector (10) exhibits satisfactory leak pressure after multiple connections and disconnections to luer lock (13) and long periods of indwell of luer tip (18).

Abstract: The present invention provides a piercing member (12) adapted for use with a flow channel. The piercing member (12) has a penetrating member (14) for piercing a solid closure, and is retained to the flow channel, but still allows fluid to flow through the flow channel (72) while retained to the flow channel (72).

Abstract: A spike assembly having an elongate spike defining a hollow cannula that is in fluid communication with the interior of a liter connection portion. The spike assembly provides needleless access to a stopper of a vial to facilitate injection and withdrawal of fluids via a syringe barrel selectively secured to the luer connection portion. The syringe can safely be removed from the spike assembly and then be directly attached to a luer compatible connector. The elongate spike may include a frangible tip portion that can break away from the spike assembly within a vial. The spike assembly may have a neck with a pair of gripping wing members. The spike assembly may have a feature that prevents rotation of the spike in the vial stopper, thereby allowing the syringe to be easily and safely disconnected from the spike assembly without having to grasp the spike assembly.

Abstract: A needless connector is provided which utilizes a resealable preslit septum valve. The valve is resiliently restrained relative to a housing with the valve and housing configured to accept a standard male luer lock having a luer tip which penetrates the valve through the opening to extend within the housing and a luer locking flange of the luer lock extending about the housing. The valve includes a disk shaped upper portion covering the opening, a lower portion spaced from the housing and extending downward from the disk shaped portion into a passageway defined by the housing, and an annular skirt to attach the septum to the housing. The connector exhibits satisfactory leak pressure after multiple connections and disconnects to the luer lock fitting and long periods of indwell of the luer tip.

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 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.
