Abstract
A control process and device for a pump is described, comprising a pump equipped with a flexible tube used in a drop-by-drop infusion systems. The infusion tube can be blocked downstream of the pump when the pump is started. The pressure created in the section of the tube located between the pump and the blockage is measured. If there is a fault in the infusion system, such as a defective pump, poor positioning of the tube in the pump, blockage or rupture of the tube upstream of the pump, the increased pressure will result in anomalies that are detected.
