Abstract
An indicator/controller for dispensing medical fluids (e.g., intravenously) is disclosed. The device has vented chambers that are movable vertically with respect to one another, thin-plate orifices, capillary chambers, and membrane valves, in addition to other features. The device need be set only once to the desired flow and it will maintain that flow rate regardless of changes in temperature or the height of fluid in the supply.
