Methods, Devices, and Systems for Coupling Fluid Lines
Fluid couplings prevent or discourage misconnection of fluid lines. In embodiments, a coupling device includes multiple male and female connectors that are joined to a common line. The coupling device is mated to a matching coupling device only when all the multiple male and female connectors are properly joined. If any of the connectors is not properly mated to a corresponding one, the coupling will leak, since the connectors on each side are joined to a furcating channel. In embodiments, the coupling devices are made unique by providing an arrangement of the connectors, number of connectors, shape of connectors or arrangement of interfering connector parts that ensure that any attempt to improperly couple two fluid lines will result in the incomplete mating and thereby cause leakage of the fluid, failure of the coupling to engage, or otherwise cause the attempt to connect to fail.
Infusion system and components thereof
Certain embodiments provide multi-medicament infusion systems for preventing the cross-channeling of medicaments. The system may include one or more of an infusion pump, medicament reservoirs, collars, a multi-channel fluid conduit, and an infusion set. The medicament reservoirs and/or collars may be sized and shaped differently such that the medicament reservoirs can only be inserted into the system selected configurations.
System and method for effecting non-standard fluid line connections
A Luer-like non-standard quick disconnect medical fluid connector that cannot be engaged with a standard Luer fitting.
Enteral feeding systems and methods
The present specification is directed to systems, devices, and methods of portable enteral pump systems for feeding and/or flushing an ambulatory patient. Embodiments provide an enteral pumping device that may be loaded by a patient from a front and a top side of the pumping device and is therefore more convenient to use. Further, embodiments incorporate a single rotor pump for dual-use purposes of feeding nutrients and flushing fluids to the patient. A pinch valve is placed between the parallel sides of the two tubes to cut off fluid flow when required. At least one sensor is also placed between the rotor pump and an outlet. The sensors are used to detect occlusions and the type of disposables used, among other purposes.
Smart connection interface
A method and apparatus for a connection interface between a reservoir or syringe, infusion set tubing, and an infusion pump is provided. The reservoir, a base and a cap are connected to form an integrated unit that is capable of being inserted and secured in an infusion pump housing. The cap and the infusion pump are each provided with at least one sensor or at least one detectable feature, arranged to interact with at least one corresponding detectable feature or sensor on the other of the cap and infusion pump device, to detect one or more of the presence, position or other characteristic of the cap when the cap is aligned or coupled with the infusion pump housing. The detectable feature and sensor may be magnetic, RF, mechanical, optical or any combination.
LOCKING ENTERAL FEEDING SYSTEM
A fluid delivery device and system is operable to fluidly couple a pair of fluid delivery conduits. One embodiment includes a fluid delivery device sized to meet ANSI/AAMI ID54:1996(R) 2005 and not mate with ANSI/HIMA MD70.1 or ISO 594/1 and ISO 594/2 standards for intravenous ports and connectors to prevent accidental intravenous delivery of fluids intended for enteral delivery. The system includes at least one of a locking tab and a stop flange configured to not mate with matching connectors not configured to satisfy the enteral feeding standards and not specifically configured to mate with the fluid delivery device.
NON-LUER CONNECTORS
Drug delivery devices having integrated non-luer connectors are described. An exemplary drug delivery device includes a container with a non-luer connector that prevents connection of a standard female luer connector to the container. One or more embodiments pertain to a container with a non-luer connector that prevents the formation of a fluid-tight seal between a standard female luer connector and the container. A non-luer connector for attachment to a container having a non-luer element is also described.
Flush enhancing male luer tip design for syringes and any luer connector
A luer connection device is disclosed having a housing including a side wall having an inside surface defining a lumen with a central axis, an proximal end, and a distal end including a male luer tip within the lumen having a central flow diverter extending outwardly from the central axis to direct a fluid to a circumferential dead space distal to the male luer tip. A luer connection device is also disclosed having a flow expansion channel disposed in the lumen tapering outward from the wall of tubular housing and partially extending along a longitudinal axis from the tip opening toward the base opening for increasing mixing and flow through a circumferential dead space in the fluid path distal to the male luer tip.
Fluid line connector device
A cap for a fluid line connector having a male luer lock fitting, the cap having a first side and a second side opposite the first side, the cap comprising a barrier and a stopper extending axially from the barrier towards the first side of the cap. The barrier defines a keyway centred on a longitudinal axis. The shape of the keyway is configured to permit a correspondingly-shaped female luer lock fitting to pass axially therethrough to engage the male luer lock fitting of the fluid line connector. The stopper is configured to prevent rotation of the correspondingly-shaped female luer lock fitting in the first circumferential direction when a lug of the correspondingly-shaped female luer lock fitting is circumferentially aligned with the stopper.
Fluid fitting for dilation instrument
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.
