A microcatheter system is disclosed which may include a microcatheter, one or more microcatheter extensions, and/or a microcatheter hub. In an embodiment, the microcatheter has a plurality of zones where the outside diameter of each zone from the distal to the proximal end has an outside diameter that is the same as or greater than the previous zone while the inside diameter is constant throughout the microcatheter length. In a further embodiment, a unique joining mechanism is employed for coupling a microcatheter to a microcatheter extension or to a microcatheter hub.

An intravenous (IV) set system comprising a primary IV set defining a primary flow line of the IV set system. The primary flow line can include multiple access points along its length and feeds to a merging fluid pathway proximate to the distal terminus of the primary IV set. At least one secondary IV set with corresponding flow lines can be separably joined to the primary IV set to cause the secondary flow lines to be in fluid communication with the primary flow line. At least one of the IV sets can have a unique set of uniform marking indicia to facilitate rapid identification of the IV sets from other IV sets within the IV set system. Such marked and identified primary and/or secondary IV sets can be allocated to specific medical functions and/or can be for use by specific medical personnel to thereby minimize risk of error in administration of an IV to a patient. The IV set system can further comprise a merging fluid pathway about a primary IV set.

A hemodialysis device is described herein. An exemplary hemodialysis device includes an import tube, a dialysis tube, and an export tube. The dialysis tube includes an inner dialysis tube, a dialysis membrane and an outer dialysis tube. The inner dialysis tube is within the dialysis membrane, which is within the outer dialysis tube. An inlet and an outlet of the inner tube are disposed at a first end of the outer dialysis tube. The inlet of the inner dialysis tube is coupled to the import tube and the outlet of the inner dialysis tube is coupled to the export tube. The dialysis tube is inserted into an artery of a patient, and thereby performs hemodialysis within the body. Since the hemodialysis in performed within the artery instead of drawing blood out of the body, the hemodialysis device will minimally affect blood pressure, which is more economic and safe.

A Luer-like non-standard quick disconnect medical fluid connector that cannot be engaged with a standard Luer fitting.

A releasable connection assembly for connecting tubing sections is disclosed. The assembly includes a dual lumen male bayonet connector and a female latch connector. The dual lumen male bayonet connector includes a first shaft and a second shaft, where each of the first and second shafts includes a distal sealing portion defining a sealing surface, a proximal coupling portion, and an annular channel. The female latch connector includes a proximal end, two sealing members and a distal end. A kit is also disclosed. The kit includes a dual lumen male bayonet connector, a blood pressure cuff, and two sections of medical tubing. The two sections of medical tubing engage each of the proximal coupling portions of the first shaft and the second shaft and the blood pressure cuff.

The invention relates to a dispense interface for an ejection device comprising a first part and a second part, at least a first opening, a second opening and a third opening, a fluidic channel and a connection element for each of the openings, wherein the first part is joined to the second part to form at least a part of the fluidic channel connecting the openings with each other and wherein at least one connection element is configured to accept a needle assembly for a fluid tight connection with the corresponding opening and wherein at least one connection element is configured to provide a releasable push fit connection for a fluid tight connection with an ejection device in order to reduce the complexity and provide an easy usage of the dispense interface and at the same time overcome the problems of material compatibility and cross contamination. The invention also relates to a system with a dispense interface according to the invention. The invention further relates to a method for preparing a dispense interface according to the invention.

A device introduced small volumes of fluid for delivery to a patient through a fluid line. The device includes a first arm adapted to receive a syringe and a second arm fluidly connected to an upstream reservoir that defines an internal volume adapted to receive a volume of fluid. The device includes a fluid obstruction mechanism configured to selectably block flow of fluid from the reservoir toward the patient, wherein the fluid obstruction mechanism transitions between a first state that permits fluid flow from the reservoir toward the patient and a second state that directs fluid flow from the syringe into the reservoir while blocking fluid flow from the reservoir toward the patient.

A connector connection indicator is mounted in a Luer male connector, or in a Luer female connector, to indicate proper mating of the two Luer connectors. The connection indicator may be or include a light source, a sound producing device (e.g., buzzer), a switch, a tactile connection indicator or an electronic chip. The electronic chip may be interposed between two conductive elements that are mounted in the Luer female connector. When the two Luer connectors are properly engaged, the electronic chip is powered via two electrical terminals. While the electronic chip is powered up it communicates with an external system via two electrical terminals. The external system interprets the communication with the electronic chip as an indication to proper engagement of the two Luer connectors. Some of the connection indicators may be mounted on a circuit board that is embedded in a void in the Luer male connector.

Certain exemplary embodiments comprise can comprise an auto-injector, which can comprise: a vial configured to store and/or contain an injectable medicament, the vial defining a vial longitudinal axis, and a housing comprising the vial. In various embodiments, the injectable medicament can be a medicine, medication, drug, pharmaceutical, prescriptive, agent, antidote, anti-venom, hormone, stimulant, vasodilator, anesthetic, and/or nutritional supplement that is substantially ready for injection.

The invention relates to a method of increasing the leak tightness of a mechanical connector of an extracorporeal blood treatment machine, wherein the mechanical connector has a pair of connection parts which have corresponding sealing surfaces, with at least one of the two sealing surfaces being wetted at least sectionally by a viscous fluid before the joining together of the connection parts and/or with the connection gap between the connection parts being covered by a sheath after their joining together. The invention further relates to an extracorporeal blood treatment machine comprising a mechanical connector which has a pair of connection parts which have corresponding sealing surfaces, with the sealing surfaces being at least sectionally wetted with a viscous liquid with a closed connector and/or with the connection gap between the connection parts of the closed connector being covered by a sheath.
