Abstract
An automated system for controlling a patient's blood glucose, including a blood glucose sensor and a processing and control unit, wherein the processing and control unit is configured to calculate, from a first mathematical model fCR specific to the patient and taking into account a single blood glucose value Gr measured by the sensor, a factor CR representative of the patient's insulin sensitivity.
Claims10
An automated system for controlling a patient's blood glucose, comprising a blood glucose sensor and a processing and control unit, wherein the blood glucose sensor is configured to measure a blood glucose value (Gr) of the patient, and wherein the processing and control unit is configured to:
- determine, based on a history of blood glucose values measured by the blood glucose sensor, a history of insulin injected to the patient, and a history of carbohydrate ingestion by the patient, a plurality of real insulin sensitivity factor (CRr) values for a plurality of events identified for the patient over a past observation period, wherein each event of the plurality of events corresponds to a continuous time range from an initial time (tinit) to a final time (tfinal) during which the insulin sensitivity factor (CRr) is isolated,
- calibrate a first mathematical model (fCR) based on the plurality of real insulin sensitivity factor (CRr) values, the calibrating comprising determining the first mathematical model (fCR) by regression from the plurality of real insulin sensitivity factor (CRr) values;
- and
- calculate, from the first mathematical model (fCR) and taking into account the blood glucose value (Gr) measured by the blood glucose sensor, a factor (CR) representative of an insulin sensitivity of the patient.
