    摘要: 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.

    摘要: A pre-slit injection site (34) includes a housing (40) with a flow path therethrough. A first end (42) of the housing (40) carries a pre-slit septum (52). One form of a blunt cannula (98), usable with the injection site (34), carries a locking member (100). When the pre-slit injection site (34) slidably receives the blunt cannula (98), the locking member (100) latches to the injection site (34) and creates a mechanically coupled unit. Another form of the cannula (280) includes a tube having a tapered distal end region (298) and having elongate discharge slots (294) for reducing contact surface area and for directing the flow laterally out of the cannula. The cannula may also include a rounded lead post (330), an annular barb (394), and axially oriented grooves (268).
