Systems, devices and method to establish fluid communication between vessels. A vessel having at least two entry ports and at least one exit port, and at least one container containing a dosing regimen, the at least one container configured to be received by one of the at least two entry ports of the vessel, whereby upon connection of the at least one container to the one of the at least two entry ports of the vessel, the dosing regimen in the at least one container is transferred into the vessel. Modular dosing system for adding at least one amount of a medicament to a preparation in a modular construction. System for displaying a dosing regimen or single amount of a medicament, so that the administrator of the amount is able to precisely ascertain the amount administered to a patient.

A syringe containing a high water content product and for use in a drug infusion system is provided. The syringe includes a plunger carrying front and rear o-rings made of a diene rubber compound such as chlorobutyl rubber or bromobutyl rubber to impart very low gas permeability characteristics to the o-rings. The plunger may be molded as a single part or in two parts. If molded as one part with radially-engaging mold portions, the seal glands in the plunger may include parting lines from the mold. If molded as two parts with axially-engaging mold portions, the front seal gland may include a sealing surface and under cut that has no parting line. The o-rings may be surface treated with a lubricant to improve sealing where the molding process gives rise to parting lines in the seal glands.

Described is a catheter patency maintenance device comprising of a flush syringe, an elongate plunger rod with a stopper slidably positioned within the barrel, a cap, disinfectant and a valve movable between an open position and a closed position. The valve may include a valve stem and/or openings in the valve to permit fluid flow. Methods of using the flush syringe assemblies are also described.

A disinfecting cap accepts a needleless injection site to apply an antiseptic agent. The cap includes a breakable seal located in a chamber between the proximal and distal portions so as to be spaced away from the opening. The cap body may include a compliant wall that deforms when a needleless injection site is inserted into the opening to removably hold the cap on the needleless injection site. In lieu of a compliant wall, a flexible skirt may extend from the cap body into the proximal portion, so that when a needleless injection site is inserted into the opening, the flexible skirt engages the outer diameter of the needleless injection site to removably hold the cap on the needleless injection site. A carrier strip may be used, wherein each of the plurality of disinfecting caps is removably attached at its proximal end to the carrier strip.

A medicament injection device comprising a main body configured to receive a medicament cartridge sealed by a penetrable barrier; a cap assembly having an inner needle part and an outer needle part, wherein the inner needle part is movable in a proximal direction with respect to the outer needle part, a needle carrier carrying a needle, the needle carrier being releasably coupled to the inner needle part, wherein, when the inner needle part is displaced in the proximal direction, the inner needle part causes the needle carrier to be displaced axially in the proximal direction; and wherein, subsequent to the axial displacement of the inner needle part, the cap assembly is separable from the main body by movement of the cap assembly in a distal direction.

The invention is related to a dispense interface for a drug delivery device for delivering at least two drug agents, comprising at least two two-ended flow regulation structures and a confluence, wherein each flow regulation structure comprises a fluid inlet opening at a first end, wherein each flow regulation structure comprises a fluid outlet opening connected to the confluence at a second end of the respective flow regulation structure and wherein at least one of the two-ended flow regulation structures comprises a capillary fluid channel. The invention is further related to a drug delivery device for delivering at least two drug agents comprising a dispense interface of the aforementioned kind, to a method for delivering at least two drug agents through an injection means of a drug delivery device and to a method for manufacturing a dispense interface of the aforementioned kind.

A combination plunger, a mixing device and a mixing syringe including the same are provided. The mixing syringe includes concentric outer and inner barrels that form an outer chamber, the inner barrel having an inner chamber. The combination plunger includes a mixing plunger and a delivery plunger and a biasing means. The mixing plunger is slidably located in the outer chamber and translated by coordinated depression of the delivery plunger to transfer a first substance from the outer chamber to mix with a second substance in the inner chamber. After the mixing stage is complete, the delivery plunger is disengaged from the mixing plunger and permitted, such as by rotation, to be further depressed in the axial direction to deliver fluid contents of the mixing syringe to a recipient. The mixing syringe needle is then retracted as result of engagement by the delivery plunger and activation of the biasing means.
