  • Patent number: 11782042
    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.

    Abstract: A fluid transfer device including a housing, a distal introducer portion configured to penetrate a needleless access connector of a vascular access device, and a wheel member rotatable with respect to the housing and operably coupled to a probe to advance and retract the probe through the distal introducer portion. The fluid transfer device also includes a connector member positioned proximate the distal introducer portion, wherein the connector member includes a pair of opposing distal clip portions, a pair of opposing proximal clip portions, and a locking member. The locking member is operably coupled to the wheel member and is configured to prevent actuation of at least a portion of the connector member when the wheel member is rotated to a first position and to allow actuation at least a portion of the connector member when the wheel member is rotated to a second position.

  • Patent number: 11744997
    Abstract: A catheter system may include a catheter adapter, a catheter extending distally from the catheter adapter, an introducer needle extending through the catheter, a flash chamber in fluid communication with a needle lumen of the introducer needle, and a seal element. 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. The seal element may be proximal to the first notch and the second notch and within the catheter between an outer surface of the introducer needle and an inner surface of the catheter. The seal element may prevent priming fluid from travelling distal to the seal element. The seal element in conjunction with the first notch, the second notch, and the flash chamber may facilitate pressure-driven blood flow into the catheter for detection of flashback and transfixing when priming occurs prior to insertion into vasculature.

  • Patent number: 11724088
    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.

  • Patent number: 11724072
    Abstract: A catheter system may include a catheter assembly, which may include a catheter adapter and a catheter extending from a distal end of the catheter adapter. The catheter system may include a needle assembly, which may include a barrel, a needle hub slidably disposed within the barrel, and an introducer needle secured within the needle hub and extending through the catheter. The needle assembly may also include a stop surface coupled to the barrel and an activation latch. The activation latch may be slidable from a first position to a second position with respect to the barrel. In response to the activation latch being in the first position, the stop surface may contact the activation latch and depression of the activation latch may be prevented. In response to sliding of the activation latch from the first position to the second position, the stop surface may not contact the activation latch, which may depress.

  • Publication number: 20230248959
    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.

  • Publication number: 20230237931
    Abstract: A vein simulator can enable a clinician to perform a PIVC workflow. This workflow can include preparation of simulated skin, insertion of a PIVC into a simulated vein, flushing a line of the PIVC and dressing and securing the PIVC to the simulated skin. The vein simulator may be formed of simulated tissue, simulated skin that is integrated into the simulated tissue and an embedded simulated vein that may be positioned within a protruding vein channel. Because the simulated skin is integrated into the simulated tissue, the vein simulator will provide a more realistic experience while practicing the workflow. A vein simulator may include one or more sensors to provide real-time feedback to a clinician while practicing the workflow.

  • Publication number: 20230211079
    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.
