Abstract: The invention includes a device having a chamber within a syringe. A fluid passageway extends through a syringe piston. A valve is associated with the passageway controlling fluid passage through the piston. The invention includes a piercing structure having a head segment and a body portion, with a channel through the body portion and through at least one surface of the head without passing through the tip. In another aspect the invention encompasses a method of preparing an agent for administration to an individual. A first component is provided within a syringe and a second component is provided within a vial. A closed valve is associated with a fluid passageway between the vial and the syringe barrel through a piston. Valve repositioning allows fluid passage and sliding of the piston joins the first and second components. Repeated sliding of the piston mixes the components to produce the medication agent.

Abstract: A syringe device includes a syringe barrel and piston having a fluid passageway extending from a vial port. Another syringe device includes a syringe barrel, a piston sleeve and an insert. A channel extends along a side of the insert. A valve controls fluid communication between the channel and the syringe barrel. Another syringe device has a syringe barrel, a piston sleeve and an insert. A valve controls fluid communication between a compartment within the insert and the syringe barrel. A method of preparing a medication includes providing a component within a syringe barrel and another component within a compartment of a piston insert. A seal is over-molded onto a tip of the insert and an end of a piston sleeve. The sleeve is rotated relative to the insert to establish fluid communication between the compartment and the barrel chamber.

Abstract: A catheter access system includes upper and lower laminated sheets. The upper sheet is integrally molded to form a plurality of longitudinally-extending syringe channels. The second sheet extends along the syringe channels to enclose them from beneath and to form a plurality of syringe barrels. An independently operable syringe plunger is slidably received within each syringe barrel. A syringe barrel selection valve is formed between the upper and lower sheets. It has a plurality of individually-selectable valve inlets, as well as a single valve outlet for fluid connection to a catheter access line in a patient. The laminated upper and lower sheets define individual fluid passages connecting individual syringe barrels to corresponding individual valve inlets. The syringe barrel selection valve can be turned to provide fluid communication between the valve outlet and any one of the syringe barrels.

Abstract: A central venous catheter initialization and access system is disclosed for initially flushing and establishing a heparin lock in multiple lumens of a central venous catheter (CVC). The system comprises a plurality of syringes integrally mounted atop a generally planar underlying support sheet in discrete and spaced groups corresponding to individual lumens of a multi-lumen CVC. Each discrete syringe group comprises at least a flush syringe and an anti-coagulant syringe. The flush syringes are pre-filled with saline, and the anti-coagulant syringes are pre-filled with heparin. A multi-position valve assembly is also mounted atop the support sheet. The multi-position valve assembly has a plurality of individual valve inlet ports in fluid communication with the respective individual syringes, and a separate valve outlet port for each discrete syringe group. The valve outlet ports have connectors which mate with the lumens of a CVC.
