1. A flow rate device for fluid control along a flow path between an infusion device and a patient comprising:
an inlet handle comprising an inlet port configured to receive fluid originating from the infusion device at a pressure within a range of 5 pounds per square inch (PSI) to 40 PSI;
an outlet handle comprising an outlet port configured to deliver fluid to the patient, the inlet handle being rotatable relative to the outlet handle; and
a fluid path disposed between the inlet handle and the outlet handle, the fluid path having at least one manually adjustable dimension which, when adjusted due to rotation of the inlet handle relative to the outlet handle during infusion, changes a flow rate of fluid exiting the outlet port, the at least one manually adjustable dimension including at least one of a width and a length of the fluid path.
