  • RETENTION FEATURE FOR SOFT INTERFACE CONNECTION
    Publication number: 20180264249
    Abstract: A retention feature configured to provide interference between a threaded connection of a Luer access device and a separate device, wherein the Luer access device further comprises a septum that provides a soft interfaced between the two threadedly connected devices. The retention features of the instant invention are designed to provide the user with a tactile sensation of a tightening threaded connection, despite a soft interface between the interconnected devices. The retention features of the instant invention further prevent “spring back” and unintentional disengagement of the interconnected devices.

  • PORTED CATHETER ADAPTER WITH INTEGRATED SEPTUM ACTUATOR RETENTION
    Publication number: 20180140820
    Abstract: A ported catheter adapter and septum actuator having various features to prevent displacement and dislodging of the septum actuator when accessing the patient's vasculature via the inserted infusion device. In particular, the systems and methods of the present invention provide an intravenous infusion device incorporating a septum actuator with a retention tab that interacts with a retention ring that is incorporated into the valve of a side port. This interaction retains the septum actuator within the lumen of the catheter adapter, thereby allowing for subsequent access to the patient's vasculature.

  • PORTED CATHETER ADAPTER HAVING COMBINED PORT AND BLOOD CONTROL VALVE WITH VENTING
    Publication number: 20170348518
    Abstract: A ported catheter adapter having a combined blood control valve and port valve, wherein the combined valve comprises one or more vents that permit the passage of air and prevent the passage of fluids. The one or more vents are located on the outer surface of the valve so as to avoid being overlapped with the pathway of the side port. As such, fluid communication between the side port and the vents is prevented. Various venting configurations are provided. The invention further includes a valve actuator that is advanced through a slit in the membrane of the valve to provide a pathway for fluid to bypass the valve.

  • ERGONOMIC IV SYSTEMS AND METHODS
    Publication number: 20170274182
    Abstract: An IV catheter system may include a catheter component with a catheter hub, a cannula extending distally from the catheter hub, and a securement platform. The securement platform may include a wing, which may extend from the catheter hub. The IV catheter system may also include a needle component with a needle hub, a needle extending distally from the needle hub along an axis, and a grip extending from the needle hub. The grip may be generally parallel to the axis and disposed on a side of the needle hub. The wing and the grip may be positioned to facilitate manipulation with a single hand to move the IV catheter system from an insertion configuration towards a fluid delivery configuration.

  • PINCH CLAMP
    Publication number: 20170232247
    Abstract: A pinch clamp for use in occluding intravenous tubing or other similar tubing can include patient comfort features and/or lateral disengagement prevention features. These features can also be designed in a manner that allows the pinch clamps to be more easily manufactured. A pinch clamp can include a first arm that is coupled to a second arm by hinges. Each of the first and second arms can form a clamping surface that are aligned when the first arm is positioned overtop the second arm. The first arm can include opposing openings and the second arm can include opposing tabs which insert through the openings when the first arm is positioned overtop the second arm. The retaining tabs interface with the openings to prevent the first arm from separating from the second arm.

  • BLOOD CONTROL CATHETER VALVE EMPLOYING ACTUATOR WITH FLEXIBLE RETENTION ARMS
    Publication number: 20170128712
    Abstract: The present invention extends to a blood control catheter valve for use in a catheter adapter. The blood control catheter value employs an actuator for bypassing a septum to open the blood control catheter valve. The actuator includes flexible retention arms positioned on one end which retract into the body of the actuator while the end of the actuator passes through the septum, and then expand outwardly to maintain the actuator positioned within the septum. This design facilitates the manufacturing of catheter adapters (as well as blood control catheter valves and other components that attach to the catheter adapter) because the design can reduce the tolerance requirements of such components. Further, the design provides a reliable blood control catheter valve that does not require the catheter adapter to be increased in size to accommodate the valve.

  • ERGONOMIC IV SYSTEMS AND METHODS
    Publication number: 20170120011
    Abstract: An IV catheter system may have a catheter component with a catheter hub, a cannula extending distally from the catheter hub, and a push feature protruding outwardly from the catheter hub. The IV catheter system may also have a needle component with a needle hub, a needle extending distally from the needle hub along an axis, and a grip extending from the needle hub, generally parallel to the axis, with a pull feature. In the insertion configuration, the needle may be positioned within the cannula and the distal end of the needle hub may be seated in a needle port of the catheter hub. In the fluid delivery configuration, the needle may be positioned outside the catheter hub. The push and pull features may be positioned to facilitate manipulation with a single hand to move the IV catheter system from an insertion configuration to a fluid delivery configuration.

  • PINCH CLAMP DEVICE
    Publication number: 20170120040
    Abstract: Pinch-style clamps can be designed for use in clamping or occluding plastic tubing, such as intravenous tubing. These pinch clamps can include a soft, polymer material applied to various surfaces of the pinch clamp to prevent abrasion or irritation to the patient, increase friction between the pinch clamp and the user operating said pinch clamp, increase friction between engaged surfaces of the pinch clamp to prevent premature or unintended disengagement of the clamp, or increase friction between the outer surfaces of the tubing and the clamping surfaces of the clamp. Various features or components can be employed to prevent lateral disengagement of the pinch clamp. A pinch clamp may also be configured with rounded outer edges to enhance patient comfort.

  • Infusion Adapter for Drug Transfer Assembly
    Publication number: 20170087297
    Abstract: An infusion adapter for connection with an infusion fluid container includes a connection portion including an anchor component for connecting to an injection port of the infusion fluid container, and a first port adapted for connection with a syringe assembly containing a medication fluid. The first port is in fluid communication with the connection portion. The anchor component is configured to securely connect the infusion adapter to the infusion fluid container to substantially prevent disconnection of the infusion adapter from the infusion fluid container once the infusion adapter is connected to the infusion fluid container.

  • Medical access device
    Patent number: 9481118
    Abstract: An access device provides needleless access to patient fluid lines such as intravascular catheters. A septum assembly of the access device is formed from a frame integrally molded with a septum and provides access for a tubular portion, such as a male luer taper of a syringe, of a medical device. The frame of the septum assembly is bonded to the housing of the device, which minimizes axial and rotational movement between the septum and the housing, so that the access device properly operates through multiple uses.

  • IV FLOW MANAGEMENT SYSTEMS AND METHODS
    Publication number: 20160287785
    Abstract: An intravenous delivery system may operate by gravity feed, and may have a liquid source containing a liquid, a drip unit that receives the liquid from the liquid source, and tubing that receives the liquid from the drip unit for delivery to a patient. A flow rate sensor may be used to measure a flow rate of liquid through the intravenous delivery system, and may generate a flow rate signal indicative of the flow rate. A controller may receive the signal, and may compare the flow rate with a desired flow rate. If the flow rate is more or less than the desired flow rate, the controller may transmit a control signal to a flow rate regulator. The flow rate regulator may receive the control signal and, in response, modify the flow rate to bring the flow rate closer to the desired flow rate.
