Abstract: A catheter access system includes a syringe body having at least two barrels. The syringe body includes an axle integrally formed thereof. Such also includes an independent fluid conduit associated with each of the two barrels. The fluid conduits extending toward a base end of the syringe body at spaced locations. An independent plunger is associated with each of the two barrels. An associated valve body has a bore provided therethrough, with the syringe body axle being received in such bore to support the valve body and syringe body relative to one another for rotation about the syringe body longitudinal axis. The valve body has a first fluid passageway positioned to align with either selected one of the syringe body fluid conduits when the valve body and syringe body are selectively rotated relative to one another. A second fluid passageway isolated from the first fluid passageway is provided in the valve body to enable air or other fluid to be discharged separately relative to the catheter.
