ABSTRACT:
Intravenous fluid is supplied under the control of a microprocessor from a reservoir to a cannula through a flow member and a flow control device which responds, via the microprocessor, to the line pressures upstream and downstream of the control device. First and second transducers and first and second check valves are connected respectively upstream and downstream of the control device, and a constant flow resistance device is connected in series with the flow-control device to enhance the accuracy of the system.
