FIELD: medical engineering. SUBSTANCE: device has sensory means and controller unit. The sensory means is usable for determining parameter value showing dropper pressure. The controller unit has means for storing and calculating data for determining parameter deviation from some reference value. The deviation indicates failure availability in dropper to enable one to give danger warning to personnel. The failure types are in particular misassembled of pump system or one of its members, connecting to an improper valve, violated dropper integrity and availability of air bubbles in the system. EFFECT: enhanced effectiveness of treatment safety control. 8 cl, 3 dwg
