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.
