Patent number: 11744997Abstract: 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.Type: GrantFiled: April 12, 2022Date of Patent: September 5, 2023Assignee: Becton, Dickinson and CompanyInventor: Weston F.

Patent number: 11724088Abstract: 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.Type: GrantFiled: May 12, 2021Date of Patent: August 15, 2023Assignee: Becton, Dickinson and CompanyInventors: Jonathan Karl Burkholz, Bart D.

Publication number: 20230248959Abstract: 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.Type: ApplicationFiled: April 14, 2023Publication date: August 10, 2023Inventors: Ralph L.

Publication number: 20230237931Abstract: 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.Type: ApplicationFiled: January 9, 2023Publication date: July 27, 2023Inventors: Dorien Butter, John Lackey, Benjamin Parker Hopwood, Ralph L.

Publication number: 20230211079Abstract: 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.Type: ApplicationFiled: March 9, 2023Publication date: July 6, 2023Inventors: S.

Publication number: 20230204464Abstract: 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.Type: ApplicationFiled: February 15, 2023Publication date: June 29, 2023Inventors: Weston F.

Publication number: 20230158275Abstract: 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.Type: ApplicationFiled: January 9, 2023Publication date: May 25, 2023Inventors: Shawn Ray Isaacson, Weston F.

Publication number: 20230137347Abstract: 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.Type: ApplicationFiled: October 25, 2022Publication date: May 4, 2023Inventors: Weston F.
