FIELD: medicine.
SUBSTANCE: group of inventions relates to methods and apparatus for assessing the glucose level in a patient with diabetes and automatically selecting an open or closed mode of the connected device for administering the drug. Glucose control device is used to measure the glucose and the corresponding impedance values from the glucose sensor connected to the person. Using the microcontroller, the said measurement results are analyzed using a probabilistic analysis means tuned to determine the overall quality indicator Qtotal. Quality index is based on smallest value of a set of quality metrics, including the accuracy probability PA glucose sensor based on glucose results set, and probability Qac of measurement quality, based on impedance values. Microcontroller evaluates the human glucose level using a recursive filter tuned to assess the glucose level based on glucose measurement results weighted by the total Qtotal quality measure. Automatically switching connected device for drug introduction by means of microcontroller between modes of open and closed control based on value of total quality index Qtotal. Information related to the estimated value of glucose level and to the selected drug administration mode is transmitted to the display. In the alternative version, a display is displayed on the display indicating that the glucose level is hypoglycemic or hyperglycemic.
EFFECT: improved insulin delivery regimen required to ensure quality control of glucose in the patient with diabetes, due to the probability-based gain factor, taking into account the quality of the input signal from the glucose sensor.
