Abstract: A method for interactive definition and management of a treatment for monitoring blood glucose of a diabetic patient includes performing two distinct, asynchronous and simultaneous, work cycles, having different length: a first local cycle, shorter, includes the steps of acquiring at least one value of said patient's blood glucose by means of a glucometer integrated in a monitoring device, calculating an insulin dosage value to be administered to the patient, by means of a computing algorithm, provided by a specialist doctor, displaying the insulin dosage on a monitoring device display, and defining a date and time for subsequent acquisition of blood glucose level. Furthermore, the system automatically sends glycemic information to the doctor, if they are beyond mean value parameters, time passed from a last contact and number of hypoglycemic value measurements, that the specialist himself can set for each patient and modify over time.
