  • Publication number: 20190314602
    Abstract: The present invention related to a catheter device having a side port in which is contained an actuator, the actuator being configured to compress a tubing of the catheter device inwardly when a separated device is inserted into the side port, thereby opening a flowpath from the side port to the inner lumen of the catheter device. In some instances, the side port actuator further comprises an antimicrobial agent or is formed from an antimicrobial material whereby the actuator prevents antimicrobial growth or colonization within fluid that remains in the side port following use thereof.

  • Patent number: 10441773
    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.

  • Publication number: 20190307989
    Abstract: An introducer needle may include a proximal end, a distal tip, and a needle lumen extending therebetween. The introducer needle may include a wall defining the needle lumen, a first notch formed through the wall, and a second notch formed through the wall. A catheter system may include a catheter adapter, a catheter extending distally from the distal end of the catheter adapter, a flash chamber coupled to the introducer needle, and the introducer needle, which may extend through the catheter. The first and second notches and the flash chamber may facilitate pressure-driven blood flow into the catheter for improved flashback and detection of transfixation when the catheter is primed prior to insertion into vasculature of a patient or otherwise.

  • Publication number: 20190120727
    Abstract: Contamination detection systems, kits, and techniques are described for testing surfaces for the presence of hazardous contaminants, while minimizing user exposure to these contaminants. Even trace amounts of contaminants can be detected. A collection kit provides a swab that is simple to use, easy to hold and grip, allows the user to swab large areas of a surface, and keeps the user's hands away from the surface being tested. The kit also provides open and closed fluid transfer mechanism to transfer the collected fluid to a detection device while minimizing user exposure to hazardous contaminants in the collected fluid. Contamination detection kits can rapidly collect and detect hazardous drugs, including trace amounts of antineoplastic agents, in healthcare settings at the site of contamination.

  • Publication number: 20190086305
    Abstract: Sampling systems and techniques that increase pickup efficiency and shedding efficiency of an analyst of interest collected from a surface are provided. In one aspect, an absorbent swab collects an analyte of interest, such as a hazardous contaminant, from a test area demarcated by a template. The sampling techniques can include swab speed and force protocols specifying how fast and how hard the user should apply the swab across the surface to improve pickup efficiency. The sampling techniques can include instructions for inverting a container enclosing the swab and collected contaminant to improve shedding efficiency from the swab.

  • Patent number: 10149937
    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.

  • Publication number: 20180280626
    Abstract: Catheter and needle assemblies with spring-powered retractable needles are described. The assemblies can include a hollow handle, a grip portion, a catheter hub with a catheter, and a needle. The needle can have a first position in which the needle is slidably disposed within the catheter and a second position in which the needle is slidably removed from the catheter and retracted at least in part into the hollow handle. The grip portion can include a trigger portion that activates a spring to move the needle from the first position into the second position. In the second position, a sharp distal point of the needle is shielded by the grip portion to prevent accidental needle sticks.

  • 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.
