FIELD: medicine.SUBSTANCE: group of inventions refers to medicine, namely to organising and conducting insulin therapy for a patient. Determining a users dose of basal insulin is ensured by using a device for insulin administration and a portable device for diabetic data control. The method involves measuring the number of the users blood glucose concentrations over the number of time intervals. The collected data are used to state if the user has performed the minimum number of measurements of the fasting blood glucose concentration over at least one of the four time intervals prescribed. That is followed by stating if the collected data indicate one of the first schedule showing the low blood glucose concentration, and the second schedule showing the lower blood glucose concentration than in the first schedule showing the low glucose concentration. Thereafter, the method provides considering if the basal insulin dose correction in the portable device for the first and second schedules correspond to each other the user is warned, and the basal insulin dose correction is prohibited in any of the devices. Taking preventive measures aiming at measuring the basal insulin dose by means of the devices involves collecting the data, and the preventive measures are taken to avoid the users hypoglycaemic state.EFFECT: group of inventions enables rendering aid in the patients suffering from diabetes by means of the devices for determining the basal insulin dose and controlling the blood dose level in an insulin dose and taking the preventive measures.27 cl, 11 dwgГруппа изобретений относится к области медицины, а именно к организации и проведению инсулинотерапии для пациента. Для определения дозы базального инсулина пользователя используют устройство для ввода инсулина и портативное устройство управления диабетическими данными. Измеряют множество значений концентрации глюкозы в крови пользователя за множество временных интервалов. Устанавливают на основании собранных данных,
