electronic infusion device. A device for monitoring intravenous infusions. The device may have an alarm in case the flow is restricted because of an occlusion of the line. In that case, the alarm will sound when a preset pressure limit is sensed. The device can also signal that an infusion is close to completion. The pressure is regulated by the height at which the container is positioned above the level of the heart when the patient is lying flat. A height of 36 in (91 cm) provides a pressure of 1.3 lb/sq in (70 mm Hg).
