5.10.2 MEDRAD VFlow Hand Controller
The VFlow Hand Controller is a sterile device intended for single patient use.
The Hand Controller works in two different modes, Variable Flow Rate and Fixed Flow Rate. When in
the Variable Flow Rate injection mode, the flow rate increases incrementally as the Hand Controller
plunger (A) is depressed, and decreases as the Hand Controller is released. In the Fixed Flow Rate
injection mode, the Hand Controller acts as a start switch, and release of the device ceases all flow.
The Hand Controller button (B) is non-functional and will beep from the Injector head and DCU when
depressed.

NOTE:
The hand controller is required to perform Variable Flow Rate injections. For

Controller" .
