Abstract
An apparatus for measuring the flow of medical liquids within an intravenous solution administration set comprises a primary tube, a secondary tube and a tertiary tube. A constricter mechanism is postiioned in the primary tube proximate the opening to the tertiary tube in order to restrict the flow of liquid therethrough. As a result, a pressure differential is created between the secondary tube and the tertiary tube when liquid flows through the primary tube. At least a portion of the secondary or tertiary tubes are transparent in order to determine the relative position of liquid in the tube. a series of markings on the tubes represent designated rates of flow. Consequently, the relative position of the liquid is used to display the rate of flow within the system.
