  • Publication number: 20230158275
    Abstract: A catheter insertion device is provided for positioning and inserting a catheter, particularly a midline catheter into a patient. The insertion device includes an actuator assembly movable with respect to a housing for deploying the catheter over a needle. A step-wise movement of the actuator advances a catheter assembly, including the catheter, in stages over the introducer needle. An indexing finger of the catheter assembly engages the actuator body during distal advancement of the actuator, and deflects as the actuator is moved proximally. The device further includes a lockout device such as a button, collar, slider, or tab, which allows movement of the catheter relative to the needle but prevents advancement of the catheter to the first stage of the step-wise movement.

  • Publication number: 20230137347
    Abstract: A fluid transfer device including a catheter, an introducer adapted to attach the device to a peripheral intravenous line (PIV), an actuator movably coupled to the introducer, and a catheter support movably coupled to the introducer. The catheter support is positioned between the actuator and the distal end of the introducer. The actuator moves the catheter between a first position disposed within the introducer and a second position where the end of the catheter extends beyond the end of the introducer and into the PIV. The catheter support includes a rigid or collapsible tether and a hub attached to the tether and defining a passageway. The catheter extends from the actuator through the passageway of the catheter support to the distal end of the introducer. As the actuator moves the catheter, the actuator contacts the catheter support and moves the catheter support with respect to the introducer.

  • Patent number: 11628290
    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.

  • Patent number: 11617831
    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.

  • Patent number: 11585733
    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.
