Patent ID: 7758547

Claim:
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.
