Method for controlling the delivery of insulin and the related system

Method for controlling the delivery of insulin in a diabetic patient comprising steps of:

• providing data representative of at least a fraction of a meal that the patient will consume;
• providing, from a block representative of conventional therapy or open loop rule that the patient is subject to, based on the data representative of at least a fraction of the foreseen meal that the patient will consume, a reference insulin value;
• providing data representative of the difference between input data, representative of a reference glycemic level, and feedback data representative of the glycemic level detected in the patient;
• providing, from a control module, based on the data representative of the difference between the input data, representative of the reference glycemic level, and the feedback data, representative of the glycemic level detected in the patient and the data representative of at least a fraction of the foreseen meal that the patient will consume, data representative of a first insulin variation value;
• providing, based on the data, representative of the first insulin variation value, and data, representative of a basal insulin value, a value of insulin to be delivered to the patient.
