    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: This invention is a protective shield (18) for a blood sampling unit that is movably engaged to an adapter (10) having a needle (12) attached. The shield attaches to a tube holder when the needle is covered by the shield. Longitudinal grooves (56) on the adapter (52) 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 re-assembled when the needle is covered by the shield. In an embodiment of the invention, a tip protector (42), removably attached to the adapter, extends through the length of the tube holder (44) 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 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.
