摘要： A cannula and injection site coupling system comprising a cannula assembly having a blunt cannula or piercing member partially surrounded by a protective shield. The protective shield is spaced apart from the blunt cannula and includes a bayonet arm, a bayonet barb, a bayonet lock and an opening or gap. The injection site has a septum with a pre-slit opening and an arm. When the cannula assembly and injection site are coupled, the injection site arm is lodged within the cannula assembly lock opening.

摘要： 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.

摘要： Disclosed is a stopper for use with containers to provide needleless access to the container with a cannula having a blunt penetrating tip. Also disclosed is a system comprising the stopper, container and cannula. The stopper includes a disc having an upper face and a lower face, and a plug extending from the disc into the container. Also included is a diaphragm, defined by a target region in the upper face and a cross channel in the disc for controlling the force needed to penetrate the stopper with the cannula. The plug includes a first inward surface for guiding the cannula and a second inward surface for engaging the cannula to minimize wetting of the outside of the cannula. In a preferred embodiment, the first surface extends down from the cross channel on the lower side of the disc, radially outwardly to a maximum diameter and the second inwardly facing surface extends down from the first surface radially inwardly to a minimum diameter to form the cannula seal. Also shown is a centrally located piercing point positioned to pre-slit the diaphragm. An overcap may be provided to alternatively have an axially aligned boss and bore positioned to pre-slit the diaphragm. In another embodiment, the invention includes an annular pre-slit disc formed of self sealing material and positioned to reduce spray back when inserting or removing the cannula.

摘要： A pre-slit injection site includes a housing with a flow path therethrough. A first end of the housing carries a pre-slit septum. A second end of the housing carries a coupling component to adapt the site to standard vials. The coupling component, a vial adapter, includes an adapter spike with openings allowing for the drainage of fluid in the vial through the spike and into the injection site. The vial adapter is provided with a skirt housing unit which protects the adapter spike in manufacturing and use. The skirt housing unit also provides features to lockingly engage the adapter with injection site to standard vials, despite dimensional variations in vial closures. Another embodiment of the coupling component is a spike having a barb feature capable of insertion into a standard vial or port and resisting disengagement.A blunt cannula is usable with the injection site combined with the coupling components.

摘要： A pre-slit injection site includes a housing with a flow path therethrough. A first end of the housing carries a pre-slit septum. 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 forming a mechanically coupled unit.

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).

摘要： 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.
