1. A process for controlling an infusion device, wherein the infusion device comprises a variable-volume container of the infusion liquid and an actuator for exerting an infusion force able to cause infusion of the liquid, the process comprising stages of:

  • activating the actuator;

    determining at least a first value of a parameter indicating an infusion force;

    verifying whether the first value satisfies a first predetermined relation with a first reference value;

    emitting at least one command signal for generating a variation in the functioning of the actuator if the relation is satisfied, the at least one command signal comprising a first command signal to the actuator and a second command signal to the actuator, a predetermined time interval lapses between the stage of emitting a first signal and the stage of emitting a second signal;

    determining at least a second value of a parameter indicating an infusion force;

    verifying whether the second value satisfies a second predetermined relation with a second reference value; and

    emitting a further signal in consequence of the verification of the at least a second value,wherein the infusion liquid is a blood anticoagulant.
