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 syringe assembly including: (1) a syringe barrel defining a chamber; (2) a plunger mounted in the chamber and moveable with respect to the barrel; and (3) a cap holder assembly containing a cap and an absorbent material removably attached to the syringe.

A cap is described for connection to a needleless connector having an open lumen, the cap includes a housing having a top wall and sidewall forming a first cavity, a flexible container, an porous absorbent material and a sealing rubber. The flexible container includes an inner thread on an inner surface, the inner thread being sufficient to interlock with a mating feature of a female needleless connector. The inner surface of the flexible container defines a second cavity. The sidewall of the housing having a split-thread protrusion integrally formed with the distal wall, an outer thread disposed on an outer surface of the split-thread protrusion, the outer thread being sufficient to interlock with a mating feature of a male needleless connector. The second cavity configured to define a chamber to contain an absorbent reservoir material, a sealing rubber and disinfectant or antimicrobial agent.

Aspects of the present disclosure relate to systems and methods for injection and retraction of a fluid. The system includes a switch configured to be activated, wherein activation of the switch activates an electrical control system. The system further includes a linear actuator that interfaces with the electrical control system. The electrical control system causes the linear actuator to depress a plunger, keep the plunger depressed for a predetermined time, and retract the plunger after the predetermined time. The system further includes a fluid reservoir engageable with the plunger, wherein the depression of the plunger causes fluid to be injected from the fluid reservoir into a connector and the retraction of the plunger causes fluid to be retracted into the fluid reservoir and out of the connector.

A device for connection to a female medical connector is disclosed, the device includes a cap, a scrubbing foam, an elastic sealing lip, and an absorbent material. The cap is configured to define a chamber to contain an absorbent material and disinfectant or antimicrobial agent. The cap may include one or more threads adapted to engage with a female luer connector. The device may also include a peelable seal to maintain sterility prior to use and to prevent the disinfectant or the antimicrobial agent from exiting the chamber prior to use. Also described are methods of disinfecting a medical connector.

A cap for a medical connector, the cap including a body having a closed proximal end and an open distal end, an interior volume within the body, an elongate member comprising an antimicrobial extending from the proximal end of body axially through at least a portion of the interior volume, the elongate member, threads for securing the cap to a medical connector, and a radially inwardly facing sealing surface on the cap, the inwardly facing sealing surface located distal to the threads and providing a liquid-tight seal between the cap and the medical connector when the cap is installed on the medical connector.

A cap is configured to provide antimicrobial protection to a female luer port of an intravenous device. The cap distributes an antimicrobial solution within the intraluminal surfaces of the port when the cap is connected to the port. A cap may also be designed to distribute an antimicrobial solution around the exterior surfaces of the port. Once connected to a port, the cap can form a seal that minimizes the evaporation of the antimicrobial solution from within the lumen of a port. The cap can therefore provide antimicrobial protection against another device that is connected to the port once the cap is removed.

Medical devices including a cap for a medical connector are disclosed. In some embodiments, the cap comprises a disinfectant, such as an antiseptic fluid and an insert configured to seal or partially seal the medical connector as it is engaged with the cap. In some embodiments the cap insert has a segment which is deformable under axially applied pressure as an end-user attaches the cap to the medical connector. In some embodiments this insert is configured to improve the exposure of antiseptic to the outer surface of the medical connector while minimizing exposure of the antiseptic inside the medical connector open lumen.

This invention pertains to systems and components useful for infusing medications such as insulin. Typically, the components are used to deliver insulin to a diabetic patient at a site of infusion over a period of time greater than 4 days. The system components typically comprise a cannula adapted for subcutaneous insertion into a diabetic patient. The system further comprises a fluid conduit adapted to deliver the insulin solution from a medication reservoir to the site of infusion and a depot in operable contact with the fluid conduit. The depot comprises selected materials including a site-loss mitigating agent (such as heparin) which inhibits inflammation at the site of infusion, and encapsulation of the cannula at the site of infusion. The site-loss mitigating agent is not premixed with the insulin, and instead is adapted to contact the insulin solution in the depot as the insulin solution flows from the medication reservoir to the site of infusion.

PIVCs with extension sets can include one or more flow diverting features for maximizing the amount of flushing that occurs within the interior of the catheter adapter. These flow diverting features can therefore minimize the amount of residual blood, medicament, or other fluid that may exist within the catheter adapter after the PIVC has been flushed via the extension set. The flow diverting features may be in the form of structural modifications to the side port of the extension set, separate components that are contained within the side port or catheter adapter, integrated components within the side port or catheter adapter, other features or some combination of any of these features.
