Provided is a system and method for a flared luer connector for medical tubing. More specifically, the flared luer connector includes a tube head adapter formed of a resilient material providing an inlet and opposite thereto an outlet with a longitudinal axis there between. A luer lock fitting is formed proximate to the inlet and structured and arranged to engage a syringe, and at least one flared member disposed between the luer lock fitting and the outlet, the flared member rising from the tube head adapter and angled towards the outlet. The flared member also provides at least one engaging surface between the tube head adapter and a distal edge, the engaging surface acutely angled with respect to the longitudinal axis. The engaging surface is structured and arranged to engage with a corresponding receiving section of a base, the base having a deflector section structured and arranged to deflect a tube head adapter having other than the corresponding flared member. An associated method of use is also provided.

A connector system for medical fluid administration has a female connection member, which can act as an access port for a container of medical fluid, and a male connection member, for accessing the container of medical fluid. The female connection member defines a sheath for receiving a portion of the male connection member and this sheath is spanned at one end by a septum, which acts to close the container of medical fluid. A lumen is defined through the male connection member to allow passage of fluid therethrough. The septum has a central region and a peripheral region, the central region being of substantially greater thickness than the peripheral region. The male connection member comprises means for rupturing the peripheral region of the septum when it is received in the female connection member to form a connection.

A concentrate container for an extracorporeal blood treatment machine with a fluid inlet at a first end of the concentrate container and a fluid outlet at a second end of the concentrate container as well as at least one connector to hold a coupling fitting of a fluid conduit, wherein at least one connector is concave in shape and is positioned inside the container. A system for use with this concentrate container, in which the coupling fittings are convex in shape. A connection piece provides for disinfection of the system.

An enteral feeding connector facilitates an increased flow rate into and through the connector to accommodate feeding fluids requiring higher flow rates for delivery. The connector includes a male connector portion including an inlet, a fluid passage in fluid communication with the inlet, and at least one connector projection at the inlet. The connector projection defines a cross-sectional area of the inlet configured to facilitate delivering feeding fluid requiring higher flow rates through the connector.

An insert for a luer-type catheter connection includes a fluid pathway connecting a female end and a male end. The male end is configured for slidable insertion into a female luer fitting of a catheter, and the female end is configured to receive a male luer nozzle of a fluid delivery device. The insert also includes a threaded collar having internal threading faced for coupling with the female luer fitting and external threading faced for coupling with a locking collar on the fluid delivery device. A cartridge located in the fluid pathway is configured to hold a patency agent and further to release the patency agent into the catheter when fluid is passed through the cartridge.

An enteral dosing control coupling comprising a cylindrical collar defining a hollow internal chamber and a lumen extension tip projecting axially into the internal chamber, the lumen extension tip defining an internal lumen extending therethrough. In example forms, the lumen extension tip is integrally formed with the cylindrical collar. In other example forms, the lumen extension tip is a separate piece and is removably engageable within the cylindrical collar.

A connector system (47, 48, 49, 50) for a medical application including a male single channel fluid connector (X) designed with an outer collar (M2) arranged concentric with an inner tube (3) and extending beyond a center collar (M1), and a female single channel fluid connector (Y) is designed with an outer collar (F1) arranged concentric with a tube (13), wherein the male single channel fluid connector (X) is interconnectable with the female single channel fluid connector (Y) to thereby form a fluid tight single channel connection for passage of fluid, and to a luer type female single channel fluid connector (YS), and wherein the female single channel fluid connector (Y) is interconnectable with a luer type male single channel fluid connector (XS). Also a system including a plurality of the connector systems is disclosed.

A one-piece fluid line connector for connecting a fluid feed line to a fluid container, comprising a main body having a male luer lock fitting, and a cap coupled to the main body by a living hinge. The living hinge is configured such that the cap is moveable to an aligned position in which the cap is aligned with a central axis of the male luer lock fitting of the main body. The cap includes a through-hole configured such that, in the aligned position, the shape of the through-hole permits a correspondingly-shaped female luer lock fitting to pass therethrough and engage the male luer lock fitting.

An apparatus includes an elongate shaft, a dilation balloon, and a fitting member. The elongate shaft includes an inflation lumen, an irrigation lumen, and at least one irrigation opening. The at least one irrigation opening is in fluid communication with the irrigation lumen. The dilation balloon is at the distal portion of the shaft. The dilation balloon is in fluid communication with the inflation lumen. The fitting member is at the proximal end of the shaft. The fitting member includes an inflation fluid port, an irrigation fluid port, and a blocking structure. The inflation fluid port is in fluid communication with the inflation lumen. The irrigation fluid port is in fluid communication with the irrigation lumen. The blocking structure is adjacent to the irrigation fluid port and defines a gap around the irrigation fluid port.

A connector unit for a blood treatment machine connects the blood treatment machine to an external container. The connector unit includes a machine-side line which is designed for being fluid-connected to the blood treatment machine, a container-side line which is designed for being fluid-connected to the container, and an attachment tightly connected to the machine-side line and to the container-side line which is designed for being detachably mounted on a connecting nozzle of the external container so as to fluid-connect the external container to the blood treatment machine. The connector unit can be included on a blood treatment machine.
