There is provided an infusion pump system for delivering a predetermined medical solution at a preset reference infusion speed. The system comprises a medical solution container； an infusion line through which the medical solution is drawn out of the medical solution container； an infusion pump configured to discharge the medical solution via the infusion line. The infusion pump is controlled so that the discharge speed of the infusion pump is computed on the basis of a current discharge speed of the infusion pump and the infusion speed of the medical solution, the resulting discharge speed is corrected by a predefined correction coefficient, and the medical solution is discharged at the corrected discharge speed.
