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. 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.

摘要： A needleless injection site comprising a housing defining proximal and distal ends and including a reseal member disposed therein. The reseal member has an elastically openable and closable aperture formed therein, and normally resides within the housing in a closed position wherein the aperture is in a closed configuration. The reseal member is deformable such that the application of distally directed pressure thereto will cause the reseal member to distally advance within the housing to an open position wherein the aperture assumes an open configuration. The removal of the distally directed pressure from the reseal member will cause it to resiliently return to the closed position wherein the aperture assumes the closed configuration.

摘要： A diaphragm fluid flow control assembly serving to provide a leak-proof seal for fluid-containing structures and serving to provide a leak-proof seal while fluid is extracted from the structures via a blunt tipped tube or needle. A perforation in the diaphragm is sealed closed by compressive forces within the diaphragm prior to insertion of a needle through the diaphragm into a fluid containing structure such as an intravenous bag, a syringe or medicament bottle. The diaphragm is also sealed after removal of the blunt tipped needle from the diaphragm. While the blunt tipped needle is inserted through the diaphragm and fluid is extracted from a fluid-containing structure, the diaphragm is in sealing engagement with the external surface of the inserted needle thereby allowing fluid to be removed from the container through the needle and preserving the sterility of the fluid. The assembly serves as a sterilization preserving transmission valve and cap for fluids stored in containers commonly used in the medical and health care field.

摘要： Small compression type injection site in the form of a self-sealing septum-like member that is self-sealing for hypodermic needle punctures and the like and a method of manufacture. Compressive stresses are introduced into a stretched elastomeric rod, whereby the decreased diameter cross section is maintained by placing a wrapping around and about the stretched rod and adhesively sealing it thereto. Sliced cross-sectional pieces of the rod then provide injection sites to be incorporated into the wall of an implantable prosthesis as by bonding or the like.

摘要： A closed system, needleless valve device includes a generally tubular body defining an internal cavity. On the proximal end of the body there is an opening which is preferably sufficiently large to receive an ANSI standard tip of a medical implement. The distal end of the body has a generally tubular skirt. The valve also includes a hollow spike having a closed tip. The spike includes at least one longitudinal 18-gauge hole located distal the tip, and is seated inside the cavity such that the tip is below the proximal end of the body. An annular support cuff is connected to the spike which seals off a portion of the cavity of the body such that an upper cavity containing the tip is defined. The valve also includes a plastic, resilient silicone seal which fills the upper cavity and opening and covers the tip of the spike so as to present a flush surface. An adaptor enables the valve to be attached to a resealable container. The valve is created by placing the spike with the seal thereon within the body. The spike and seal are preferably prevented from being removed from the body by at least one retaining tab that is created during assembly of the valve by gouging material from an inner surface of the body with a gouging bit as the valve is assembled.

摘要： A medication delivery and monitoring system and methods whereby drugs are safely delivered to a patient, monitored in real-time during delivery and crucial events are recorded during delivery to provide real-time, on-line information and detail for an audit trail. A novel safety label cradle unit is disclosed. Safety label cradles (SLC's) are provided in a plurality of sizes to match varying sizes of syringes which are disposed on a cradle of the SLC to provide a constant needle height on the SLC unit independent of syringe volume (barrel diameter). A selected SLC is securely affixed to a syringe by an adhesively backed label wrapping. The label is preprinted to provide drug identification indicia and drug preparation information. The information is automatically read into the system from the label. A novel delivery station of the system monitors drug delivery as a plunger of the syringe is pushed to deliver a drug to a patient. A smart tray in cooperation with a slider portion of the SLC is used to selectively deliver drugs to a port in the IV set. The smart tray comprises a first portion for carrying SLC units, an attachable second portion having a control panel for operating the system and a cover for lockably affixing the SLC units to the tray.

摘要： A needle connector assembly for attachment to an IV receptacle which includes a needle hub with a cannula or needle attached thereto and a housing to which the needle hub is mounted. The hub has a plurality of equi-spaced splines thereon and the housing has an aperture in the rear portion thereof defining a plurality of equi-spaced slots therein which mate with the splines when the hub and the housing are secured together. Along the length of the interchangeable splines and slots, an inwardly projecting, one-way barb is provided which has an inclined or cam surface at its leading edge. When the hub is inserted into the housing, the needle is completely surrounded by the housing and the barbs bite into the adjacent material to preclude withdrawal of the hub from the housing. The housing and the receptacle may interlock with each other at a patient IV site to secure the housing to the receptacle.

摘要： A female luer connector for intravascular or urological use is provided with a needle having a closed distal end with an opening in the side of the needle. In addition, the needle is sealingly received within a recess of a rubber septum with an interference fit between the distal end of the needle and the septum. A slit may be formed in the septum to facilitate penetration of the needle through the septum when in use. In one embodiment, the septum has an elongated recess so that the needle may be received under compression in one portion for storage purposes and in a second portion when in use.
