Abstract: A catheter assembly (10) may include a catheter adapter (12), which may include a body (14) and a side port (16) extending outwardly from the body. The body may include a distal end (18), a proximal end (20), and an inner surface (22) extending through the distal end and the proximal end and forming a lumen (24). The catheter assembly may include one or more components to facilitate flushing of the catheter assembly. For example, an angle of the side port with respect to a longitudinal axis of the body may be adjustable. The catheter assembly may include a catheter (26) extending distally from the distal end of the catheter adapter. The catheter assembly may include a septum (30) disposed within the lumen proximal to a side port pathway extending through the side port and in fluid communication with the lumen.

Abstract: An air stop membrane can be used within an IV set to maintain a fluid column within the IV set downstream of the membrane even after a fluid bag has emptied. By maintaining a fluid column downstream of the membrane, air is prevented from entering into the tubing that couples the IV set to a vascular access device. For this reason, once a fluid bag has emptied, a new fluid bag can be coupled to the IV set without needing to re-prime the IV set. Therefore, a clinician need not be present as a fluid bag is emptying to ensure that air does not enter the tubing.
Abstract translation: 即使在流体袋已经排空之后，也可以在IV集中使用挡风膜以将流体柱保持在膜下游的IV集合体内。 通过在膜的下游保持流体柱，防止空气进入将IV组耦合到血管进入装置的管中。 因此，一旦流体袋已经排空，新的流体袋可以连接到IV套件，而不需要重新填充IV套件。 因此，当液体袋排空以确保空气不进入管道时，临床医生不需要存在。

Abstract: A catheter assembly and/or an introducer may include one or more features configured to guide a probe and/or a catheter distally through a septum. The catheter assembly may include a catheter adapter, which may include a distal end, a proximal end, and a lumen extending there between, and a septum disposed within the lumen. The septum may include a proximal surface that is tapered inwardly in a distal direction such that the proximal surface of the septum is configured to guide the probe and/or the catheter distally through the septum. The catheter assembly may be configured to receive an introducer, which may include an introducer element. A proximal end of the introducer element may include another proximal surface that is tapered inwardly in the distal direction such that the other proximal surface is configured to guide the probe or the catheter distally through the septum.

Abstract: An intravenous delivery system may have a liquid source containing a liquid, tubing, and an anti-run-dry membrane positioned such that the liquid, flowing form the liquid source to the tubing, passes through the anti-run-dry membrane. The anti-run-dry membrane may be positioned within an exterior wall of a drip unit, and may be secured to a seat of the exterior wall by an attachment component. The attachment component may have various forms, such as a secondary exterior wall that cooperates with the exterior wall to define a drip chamber, a washer positioned such that the anti-run-dry membrane is between the washer and the seat, and an adhesive ring formed of a pressure sensitive adhesive and secured to the anti-run-dry membrane and the seat via compression. Interference features may protrude inward from the exterior wall or outward from the anti-run-dry membrane to help keep the anti-run-dry membrane in place.

Abstract: A catheter system 10 including a catheter adapter and a wing 24 extending outwardly from the catheter adapter. The wing includes a groove or slot 40. The system includes a needle hub 12 and a paddle 14 extending outwardly from the needle hub. The paddle includes an extension 42 disposed within the groove or the slot to reduce axial movement between the catheter adapter and the needle hub. The extension may be removable from the groove or the slot to allow axial movement between the catheter adapter and the needle hub during removal of the needle hub from the catheter adapter, for example. The paddle and/or the wing may include a shape to reduce axial movement between the catheter adapter and the needle hub, which may also be advantageous during insertion of the catheter system.

Abstract: An intravenous delivery system (100) may have a liquid source (102) containing a liquid (122), tubing (106), and an anti-run-dry membrane (136, 320, 420, 720) positioned such that the liquid (122), flowing form the liquid source (102) to the tubing (106), passes through the anti-run-dry membrane (136, 320, 420, 720). The anti-run-dry membrane (136, 320, 420, 720) may be positioned within an exterior wall (133, 310, 410, 710, 1110) of a drip unit (134, 300, 400, 700, 1100), and may have a weld surface (346, 446, 746) secured to a seat (334, 434, 734, 1134) of the exterior wall (133, 310, 410, 710, 1110) via application of compression to press the weld surface (346, 446, 746) against the seat (334, 434, 734, 1134), and application of coherent light (352) or vibration. In response to application of the coherent light (352) or vibration, localized melting may occur, causing the weld surface (346, 446, 746) to adhere to the seat (334, 434, 734, 1134). The anti-run-dry membrane (136, 320, 420, 720) may be modified to have a melting point close to that of the seat (334, 434, 734, 1134). Ultrasonic or laser welding may be applied in a manner that causes portions of the seat (334, 434, 734, 1134) to melt and flow into pores (138) of the weld surface (346, 446, 746).

Abstract: An intravenous delivery system may have a liquid source containing a liquid, tubing, and an anti-run-dry membrane positioned such that the liquid, flowing form the liquid source to the tubing, passes through the anti-run-dry membrane. The anti-run-dry membrane may have a plurality of pores through which the liquid flows, and may be formed of a hydrophilic material that resists passage of air through the pores. The intravenous delivery system may further have a bubble point raising component that raises the bubble point of the anti-run-dry membrane. The bubble point raising component may, in some embodiments, be a high surface energy coating or additive.

Abstract: An extension (20) for a catheter assembly (10) may include a distal end and a proximal end. The distal end may include one or more cantilever arms (= 26) and an insertion feature (24) spaced apart from the cantilever arms. The insertion feature may be configured to insert into a lumen of a catheter adapter (12) to provide a fluid connection between the catheter adapter and the extension. The one or more cantilever arms may be configured to engage in a snap-fit with the catheter adapter. The proximal end of the extension may include a female luer fitting (30).
