ABSTRACT:
A novel fluid flow regulating device for varying the rate of flow of fluids for infusion to a patient at extremely low but constant flow rates. The regulator device is interposed at a point on a supply tube between a fluid reservoir and a patient. An input port directs fluid to a fluid metering groove of variable cross-sectional area on a metering plate which is formed as a part of the output port. The metering plate is rotated axially, relative to the input port, allowing fluid to enter the fluid metering groove at any point and flow toward the output port through a fluid metering groove which increases in depth or cross-sectional area at an essentially constant rate. Depending on the point at which the fluid enters the fluid metering groove flow path, the flow rate selected can be any rate from full off to full flow.
