Abstract
A system for the intravenous infusion of pharmaceuticals uses a syringe assembly, and a flexible tube for connection to a Y-connector in an intravenous drip assembly through which tube diluent fluid may flow from the drip assembly through the connector assembly to the syringe body, and through which diluted, dissolved or suspended pharmaceutical may pass from the syringe body to the Y-connector. The syringe assembly has an elongated body, a piston movable longitudinally within and in sealing engagement with the body, a plunger for insertion into one end of the body to move the piston, a penetrable closure at the other end of the body, and a connector assembly for establishing a passage for liquid between the interior of the body and the tube, the connector assembly comprising first and second cannulas projectable through said penetrable closure, a coupling for establishing connection between the first cannula and the tube, an air valve establishing a controlled connection to the exterior of the connector assembly, and a connection between the second cannula and the air valve.
