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 intravenous (IV) catheter system may include a catheter adapter having a proximal end and a distal end. The IV catheter system may also include a cannula extending through the catheter adapter. A proximal end of the cannula may include a notch. The IV catheter system may also include a needle hub, which may be coupled to the proximal end of the catheter adapter. The needle hub may include a flashback chamber, which may be in fluid communication with the notch when the IV catheter system is in an insertion configuration.

Abstract: Pinch clamps are provided which generate positive displacement while also preventing rebound. To prevent rebound while providing positive displacement, the upper and lower clamping surfaces may be configured to form a pinch profile along which the tubing is compressed with the pinch point being formed at the distal end of the pinch profile. To further prevent rebound, the lower arm of the pinch clamp can include blocking ribs that interface with the upper clamping surface to prevent distal travelling of the pinch point even if the upper arm is forced into an over-engaged position.

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: 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 have a weld surface secured to a seat of the exterior wall via application of compression to press the weld surface against the seat, and application of coherent light or vibration. In response to application of the coherent light or vibration, localized melting may occur, causing the weld surface to adhere to the seat. The anti-run-dry membrane may be modified to have a melting point close to that of the seat. Ultrasonic or laser welding may be applied in a manner that causes portions of the seat to melt and flow into pores of the weld surface.

Abstract: An extension for a catheter assembly may include a distal end and a proximal end. The distal end may include one or more cantilever arms and an insertion feature spaced apart from the cantilever arms. The insertion feature may be configured to insert into a lumen of a catheter adapter 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.

Abstract: An intravenous delivery system may have a liquid source containing a liquid, tubing, and a vent cap. The tubing may be connected to the liquid source and the vent cap to convey liquid from the liquid source to the vent cap. The vent cap may have a vent that is substantially impermeable to the liquid and permeable to air, and therefore releases air from the liquid from the vent cap. The vent cap may also have a chamber in communication with the vent. The chamber may have a volume selected to enable the chamber to receive a quantity of liquid from the tubing in which the air, if entrained in the liquid, is likely to reside after the tubing has been primed with the liquid.
Abstract translation: 静脉内输送系统可以具有液体源，其包含液体，管道和通气盖。 管道可以连接到液体源和通气帽以将液体从液体源传送到通气盖。 通气盖可以具有基本上不透液体并且可渗透空气的通气口，并且因此从通气盖排出液体中的空气。 排气盖还可具有与排气口连通的室。 腔室可以具有选择的体积，以使腔室能够从管道接收一定量的液体，其中如果夹带在液体中的空气在管道已经被液体灌注之后可能驻留。

Abstract: A catheter assembly (10) comprises a catheter (20), a needle (22) having a sharp distal tip and disposed within the catheter (20), a catheter hub (30) connected to the catheter (20) having the needle (22) passing therethrough, and a housing (70) that encloses the sharp distal tip of the needle (22). An external surface of the catheter hub (30) and an internal surface of the housing (70) each include at least one of a channel member (34) and a raised portion (72) that interfit to restrict motion between the catheter hub (30) and the housing (70).

Abstract: A vascular access device to passively open a fluid path within a vasculature. The vascular access device may include a catheter and a guidewire. The catheter may have a proximal end, a tip, and a length of tubing therebetween. The guidewire may extend along the length of tubing and may include a bent portion. At least a portion of the length of tubing may substantially conform to the bent portion such that the tip of the catheter avoids an obstruction within the vasculature.
