  • Publication number: 20200164200
    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: 20200155809
    Abstract: A compliant catheter adapter may include a catheter adapter body formed of a compliant material. The catheter adapter body may have a generally elongate shape and an inner chamber. The catheter adapter body may include a compression resistant septum disposed toward the proximal end of the catheter adapter body. The compression resistant septum may have a lumen configured to receive an elongate object. The compression resistant septum may also be coupled to a compression cap that imparts a compression force on the compression resistant septum such that the lumen narrows and seals when the elongate object is removed from the lumen.

  • Publication number: 20200155808
    Abstract: Catheter systems comprising independent fluid paths are disclosed. The catheter systems can include a catheter adapter that has a catheter hub with a chamber. A catheter extends from a distal end of the catheter hub and is in fluid communication with the chamber. A stabilization platform with a first wing and a soft push tab are also part of the catheter hub. The catheter system includes a needle hub with a needle that slidably fits within the catheter. In an insertion configuration, a proximal extension of the catheter hub is removably coupled within a distal opening of the needle hub. After the catheter is placed, the needle hub is retracted from the catheter adapter to slidably remove the needle from the catheter.

  • Patent number: 10639455
    Abstract: An IV access device can include a needle hub that incorporates a flash chamber. The flash chamber can be used to provide visual confirmation of proper catheter placement within a vein. The flash chamber can include a path-defining structure to facilitate identifying whether blood is continually flowing into the flash chamber. The flash chamber may also be removable from the needle hub. In some cases, the needle hub may include a paddle grip that facilitates insertion of the catheter and separation of the needle hub from the catheter adapter.

  • Publication number: 20200121911
    Abstract: PIVCs with extension sets can include one or more flow diverting features for maximizing the amount of flushing that occurs within the interior of the catheter adapter. These flow diverting features can therefore minimize the amount of residual blood, medicament, or other fluid that may exist within the catheter adapter after the PIVC has been flushed via the extension set. The flow diverting features may be in the form of structural modifications to the side port of the extension set, separate components that are contained within the side port or catheter adapter, integrated components within the side port or catheter adapter, other features or some combination of any of these features.

  • Publication number: 20200101265
    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 adjacent to 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.

  • Patent number: 10589063
    Abstract: An obturator can include antimicrobial features which assist in sterilizing or maintaining the sterility of fluid contained within a vascular access device while the device is not being used for infusion or other access to the patient's vasculature. These antimicrobial features include antimicrobial coatings applied to various surfaces of an obturator and antimicrobial components bonded or otherwise secured to an obturator. Various combinations of antimicrobial coatings and/or components can be used on an obturator as necessary to provide a desired amount of antimicrobial agents within a particular enclosed volume of a vascular access device.

  • Publication number: 20200078515
    Abstract: A cannula capture mechanism is described herein. The capture mechanism may include an inner housing, outer housing, and a cannula. The outer housing may be configured to move between a compressed and a decompressed state. An outer surface of the inner housing may include one or more interlock components. When the cannula is exposed from a distal end of the inner housing, the one or more interlock components may interact with one or more interlock surfaces formed in another surface of the catheter device. When the cannula is retracted proximally within the inner housing, the inner housing may contract radially inward causing the one or more interlock components to be separated from the one or more interlock surfaces and the outer housing to move to the decompressed state and extend distally over a distal portion of the inner housing.

  • Publication number: 20200078579
    Abstract: A catheter adapter may include a distal end, a proximal end, a lumen extending between the distal end and the proximal end, and a side port. A central axis of a fluid path extending through the side port may be disposed at an angle with respect to a longitudinal axis of the catheter adapter. The angle may be less than 45°. Additionally or alternatively to the angle being less than 45°, the catheter adapter may include a wedge and/or an insert configured to facilitate instrument delivery to the catheter assembly via the side port.

  • Publication number: 20200061345
    Abstract: An integrated vascular access device can include strain relief features to minimize the likelihood of the extension tubing becoming kinked during use. These strain relief features can be configured at both ends of the extension tubing to minimize the likelihood of kinking at the interfaces to the catheter adapter and luer adapter. To provide strain relief at the catheter adapter end of the extension tubing, an interface formed of a flexible material can be aligned with an extension of the catheter adapter into which the extension tubing inserts. The interface can be integrated into a stabilization platform or formed separately from a stabilization platform. To provide strain relief at the luer adapter end of the extension tubing, a flexible spacer can be coupled to a distal end of the adapter and have a distal portion that is positioned around the extension tube.
