A connector for medical fluid vessels includes a fluid-seal fitting such as a male plug defining a lumen and mating with a cooperating connector, a mechanical fastener such as a screw thread for mating with the cooperating connector, and an outer housing positioned around the plug to form an annular space. A cap can be provided with a fluid-seal fitting such as a male plug for mating with the lumen of the connector. In example embodiments, the male plug is tapered and can comprise one or more projections for sealingly engaging with the lumen of the connector. According to some example embodiments, the cap can be tethered to the connector.

A self activating vent cap configured to be operably coupled to a needleless connector and automatically shifted relative to the needleless connector from the first, storage position to a second, activated position upon rotation of the vent cap relative to the needleless connector. The self activating vent cap including a threaded portion, an activation portion and a biasing mechanism, wherein shifting of the activation portion to the second, activated position is selectively precluded by the interference of at least one ridge of the threaded portion with a ledge of the activation portion.

A catheter system may include a needleless connector, which may include a distal end, a proximal end, and a valve disposed between the distal end of the needleless connector and the proximal end of the needleless connector. The catheter system may include a vent assembly, which may include a proximal component and a distal component. The proximal component may include a male luer adapter, which may include a male luer. The distal component may include a distal end coupled to the proximal end of the needleless connector, and a proximal end coupled to the male luer adapter. In response to movement of the proximal component from a proximal position to a distal position with respect to the distal component, the male luer of the male luer adapter may open the valve to vent air inside the catheter system.

A catheter system may a catheter assembly, which may include a catheter adapter and a catheter. The catheter system may also include a needle assembly, which may include a needle hub and an introducer needle. A proximal end of the introducer needle may be secured within the needle hub, and a distal end of the introducer needle may extend beyond a distal end of the catheter. The catheter system may include a vent plug. A distal end of the vent plug may include a male luer adapter, which may include a cannula and a collar surrounding the cannula. The cannula may include a cavity to receive blood flowing proximally through the introducer needle. A proximal end of the cavity may be formed by a wall extending across the cannula and disposed within the needle hub. The cannula may be inserted into proximal end of the needle hub.

An infusion tube system and a method for manufacture are provided. An infusion tube system including an infusion tube and a connector attached to the infusion tube at an end of the infusion tube is disclosed. The connector has a proximal end and includes a connector body extending from a distal end to a proximal end along a center axis and defining a cavity. The connector body includes an end wall with an inner surface, and at least one vent opening, and a sidewall extending from the end wall along the center axis with an inner and outer surface. The connector includes a membrane covering the at least one vent opening, the membrane being welded to the inner surface of the end wall along at least one welding seam including a first welding seam such that the membrane covers and seals the at least one vent opening.

An air venting device may include an adapter comprising a tubular body having a hollow interior defining a fluid flow path, and a vent plug detachably coupled to at least a portion of the tubular body. The vent plug may include an inner circumferential surface defining an internal chamber of the vent plug, and the fluid flow path of the adapter may fluidly communicate the adapter with the internal chamber of the vent plug. The vent plug may further include a superabsorbent polymer material disposed in the internal chamber. The superabsorbent polymer material may be configured to (i) absorb a liquid entering the internal chamber from the fluid flow path, and (ii) expand in volume as the liquid is absorbed into the superabsorbent polymer material. Air entrained in the liquid entering the internal chamber may be vented to an exterior of the air venting device via the vent plug.

Provided is a fluid wicking tip. The fluid wicking tip includes a plurality of drip flanges arranged to wick fluid between narrow spaces defined between any two drip flanges. The narrow spaces are dimensioned to facilitate wicking by capillary action. Also provided is a syringe that includes the fluid wicking tip. Also provided is a spike tip including a series of tiered drip flanges for retaining fluid spilled from a bulk fluid container during a syringe filling operation.

A catheter system may include a luer adapter, which may include an outer surface having threading or a recess. The catheter system may also include a flow control plug, which may include a proximal end and a distal end. The proximal end of the flow control plug may include a filter element permeable to air and not to blood. The distal end of the flow control plug may include a cylinder and a taper-shaped luer tip spaced apart from the cylinder. An inner surface of the cylinder may include a protrusion engaged in a snap-fit with the recess or corresponding threading mated with the threading.

A multi-tubing intravenous (IV) extension set may include an outlet tubing fluidly coupled to a primary multi-tubing connector at one end and fluidly coupled to a vascular device at an opposite end, and a primary inlet tubing having a proximal end with an adapter for connection to a syringe containing a priming or a medicinal fluid, and a distal end coupled to the primary multi-tubing connector. The IV extension set may further include at least one secondary inlet tubing with a proximal end having an adapter for receiving a medicinal fluid and a distal end selectively fluidly coupled to the primary multi-tubing connector. A slide clamp may be positioned on the outlet tubing to restrict flow between the proximal and distal ends of the outlet tubing and cause priming fluid flowing into the outlet tubing via the multi-tubing connector to reverse direction into the at least one secondary inlet tubing.
