Evaluation of the Arm-A-Flow Intravenous Flow Regulation

Abstract:

The Arm-A-Flow intravenous flow regulator is a gravity-flow infusion device that uses a pressure-sensitive component in addition to a value to control intravenous I.V. flow. When this regulator is placed between the I.V. administration set and the catheter, it is simply a more accurate way of controlling the I.V. flow instead of using the administration set I.V. tube clamp. In contrast to electronic flow controllers which control the flow by counting the drops, the Arm-A-Flow regulator controls flow by monitoring changes in pressure. The Arm-A-Flow regulator has a pressure-sensitive diaphragm in addition to a valve. This diaphragm automatically readjusts the orifice opening when there is a change in flow so that the difference is accommodated for, and the solution continues to be dispensed at the set rate. The Arm-A-Flow regulator was found acceptable for use on board aeromedical evacuation aircraft. This technical paper presents the results of the United States Air Force School of Aerospace MedicineChemical Defense Branch, Aeromedical Research Function evaluation of the Arm-A-Flow regulator.
