ABSTRACT:
Metering apparatus for metering the flow of fluid through an administration set includes a peristaltic-type metering pump which repeatedly and progressively compresses a section of vinyl tubing of the administration set to provide a desired flow rate. For improved metering accuracy the fluid is maintained under pressure downline of the metering pump by a downline occlusion station. A protective circuit responsive to the pressure in the tubing downline of the occlusion station stops the metering apparatus and sounds an alarm in the event the pressure in the tubing exceeds a predetermined level, as in the event of an occlusion, downline of the metering apparatus and upline of the patent.
