1. A variable flow rate infusion system, comprising:
an infusion device that dispenses fluid pressurized to between 5 PSI and 40 PSI; and
a manually-adjustable flow control device in fluid communication with the infusion device by way of tubing and configured to receive fluid dispensed by the infusion device, the flow control device comprising:
a circular inlet handle including an inlet port, the inlet port being positioned offset a first distance from a center of the inlet handle;
a circular outlet handle including an outlet port, the outlet port being positioned offset a second distance from a center of the outlet handle, the first distance being smaller than the second distance; and
a seal sealingly engaged between the inlet handle and the outlet handle;
wherein:
manual rotation of at least a portion of the inlet handle relative to the outlet handle changes a width of a fluid path in the outlet handle which results in a change of a rate of fluid flow passing through the flow control device.
