  • Publication number: 20230256205
    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.

  • 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.

  • 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: 20230145227
    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: 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.
