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 catheter priming apparatus may include a barrier forming a reservoir. Fluid may be disposed within the reservoir. A support structure may be disposed within the barrier. The support structure may include an opening extending through the support structure and a connector configured to couple the catheter priming apparatus to a catheter system. A one-way valve may be coupled to the support structure and configured to allow the fluid to flow out of the reservoir through the connector in response to compression of a portion of the barrier aligned with the opening.

A catheter system may include a catheter assembly, which may include a catheter adapter and a catheter extending from a distal end of the catheter adapter. The catheter system may include a needle assembly, which may include a barrel, a needle hub slidably disposed within the barrel, and an introducer needle secured within the needle hub and extending through the catheter. The needle assembly may also include a stop surface coupled to the barrel and an activation latch. The activation latch may be slidable from a first position to a second position with respect to the barrel. In response to the activation latch being in the first position, the stop surface may contact the activation latch and depression of the activation latch may be prevented. In response to sliding of the activation latch from the first position to the second position, the stop surface may not contact the activation latch, which may depress.

A personal accessory kit (PAS) for a breast pump is provided. The PAS and breast pump together form a complete breast pump system. The PAS has a locking mechanism to lock a diaphragm base of the system to a cap of the diaphragm of the system. The PAS further has an ergonomically-shaped handle. A flattened port adapter plug is provided for reducing single pumping vacuum pressure when a single port of the breast pump is used. The adapter allows for the safe utilization of a single port of a breast pump.

The invention relates to medical technology, and more particularly to a device for the conservative treatment of nasal and paranasal sinus diseases. The present device comprises obturators for the posterior and anterior nasal openings, each obturator being in the form of an expandable sheath made of a resilient material and provided with a feed tube. The distal end of the tube is in communication with the cavity below the sheath, and the proximal end is provided with an adapter having a valve mechanism. The obturator sheath for the posterior nasal opening is hermetically fastened to the distal portion of its feed tube. The obturator sheath for the anterior nasal opening is hermetically fastened to a cuff. The cuff is provided with two channels, one of which holds the feed tube of the obturator sheath for the posterior nasal opening in such a way that the cuff can move along the entire length of the feed tube. The other channel holds a catheter for evacuating a pathological secretion from the paranasal sinuses and/or for introducing solutions of medicinal preparations into same for diagnostic or therapeutic purposes. The catheter is held in said channel in such a way that the distal portion thereof can be moved into the space between the obturator sheaths. The invention is intended to provide more effective treatment of nasal and paranasal sinus disorders.

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.

Described is a medical adapter assembly comprising an end including a neuraxial fitting that is not directly connectable to a standard luer fitting, an opposing end including a fitting connectable to an intravenous medical device, and a check valve that allows fluid flow from the end with the standard luer fitting to the end with the neuraxial fitting, but prevents fluid flow from the end with the neuraxial fitting to the end with the standard luer fitting. Methods of using the medical adapter assembly and kits containing the medical adapter assembly are also described.

A fluid distribution system is configured to distribute fluid from a first vessel to second vessels includes a hub assembly and a frame assembly. The hub assembly has an input cap, a distribution cap, a first clamp, and a second clamp. The input cap defines an inlet and the distribution cap is sealingly secured to the input cap with a plenum being defined between the input and distribution caps. The distribution cap includes conduit connectors that each defines an outlet in fluid communication with the plenum. The first clamp is disposed over the distribution cap and is engaged with the input cap to secure the input cap to the distribution cap and the second clamp is disposed over the input cap and engaged with the distribution cap to secure the distribution cap to the input cap. The frame assembly supports the hub assembly and is configured to secure each of the secondary vessels at a predetermined distance relative to the hub assembly.

A injection site information cap includes a housing, a cover portion, an engagement portion configured to couple to and cover an injection port of an injection site, and at least one information element on the cover portion that is positioned to be automatically sensed by at least one sensor of the injection site when the engagement portion is coupled to or is being coupled to the medication injection port. Related apparatus, systems, and techniques are also described.

A medical connector can include a body having a fluid path with an inlet port, an outlet port, a luer portion, and a post extending through a fluid path. An arm having a latch member is coupled to the body to engage a ridge or thread on an exterior surface of a reciprocal connector. The arm may also include an extension. When the connector is in an open position, the latch member restricts retraction of the reciprocal connector from the outlet port. A seal is coupled to the body and includes a flap extending across the outlet port or a bellows to compress along an axis. In a closed position, the post restricts flow through the luer portion. In an open position, the post permits flow through the luer portion.
