Blood glucose control system and method

A blood glucose control system comprising:

• a continuous blood glucose meter configured to continuously measure blood glucose of a patient;
• a bio-signal sensor configured to acquire a bio-signal of the patient;
• a lifelog data collector configured to collect lifelog data of the patient;
• an insulin injection controller configured to,
• obtain an insulin activation curve from insulin activation peak time information of the patient;
• obtain a time-based blood glucose change amount from blood glucose measurement information of the patient;
• calculate, based on the insulin activation curve and treatment history information of the patient, an amount of remaining insulin that is not activated in the patient's body;
• determine, based on the patient's treatment history information, a variability of an insulin injection amount;
• predict an amount of blood glucose consumption from the lifelog data of the patient by considering an amount of physical activation of the patient;
• predict an amount of change in blood glucose by considering one or more of an amount of food and an amount of sleep of the patient;
• learn information on the time-based blood glucose change amount, the amount of remaining insulin, and the variability of the insulin injection amount, based on the insulin activation curve;
• learn information on the predicted amount of blood glucose consumption and the predicted amount of change in blood glucose, based on the lifelog data;
• learn information on the bio-signal of the patient or a stress level of the patient indexed based on the bio-signal, and
• determine the insulin injection amount and an injection rate based on a learned model;
• and
• an insulin pump configured to inject insulin into a body of the patient according to the insulin injection amount and the injection rate determined by the insulin injection controller.
