Abstract

See full text

Sequential, continuous delivery of separate intravenous fluid mixtures is facilitated by a float operated valve which automatically re-starts flow from a primary solution when the selected volume of secondary fluid has been infused. The float is contained in a calibrated volumetric chamber with a drug injection port, and valved connections to primary and secondary solutions. Selected volumes of primary or secondary solution can be added to the chamber and mixed with drugs inserted through the injection port. Fluid in the calibrated chamber raises a float which closes a valve and stops fluid flow from the primary solution source. Fluid from within the chamber flows to the patient until very little fluid remains in the chamber and the float moves downward causing the valve to the primary solution to open allowing a continuous flow of intravenous fluid to the patient.
