VERFAHREN ZUR BESTIMMUNG EINES BOLUS, DAS DURCH EINE INSULINABGABEVORRICHTUNG VERABREICHT WIRD, COMPUTERPROGRAMMPRODUKT UND DATENVERARBEITUNGSVORRICHTUNG

The present disclosure refers to a method of determining a bolus to be administered by an insulin delivering device is disclosed. The method comprises, in a data processing device having one or more processors, receiving glucose measurement data indicative of glucose level measurement signals detected by a continuous glucose sensor for a person; and determining by the one or more processors at a point in time, for the person, an insulin bolus to be administered by the insulin delivering device, the insulin bolus determined based on a functional relationship provided by a formula comprising formula expressions indicative of a glucose level derived from the glucose measurement data; a carbohydrate-to-insulin ratio (CIR); and an insulin sensitivity factor (ISF).The determining further comprises at least one of: for the carbohydrate-to-insulin ratio, determining a present CIR value based on CIR data indicative of the carbohydrate-to-insulin ratio for at least one of a time period from the start of a previous meal until before the start of a current meal on a present day comprising the point in time, the current meal, and the previous meal; and for the insulin sensitivity factor, determining a present ISF value based on ISF data indicative of the insulin sensitivity factor for at least one of the time period from the start of the previous meal until before the start of the current meal on a present day comprising the point in time, the current meal, and the previous meal. The determining of the insulin bolus is conducted by a data processing device provided in a system selected from the following group: an insulin pen; an insulin pump; a remote control device configured to remotely control an insulin pump or an insulin pen; a continuous glucose meter; a controller of a continuous glucose meter; a blood glucose meter; and a portable device such as mobile phone, tablet computer or smart watch. Further, a computer program product and a data processing device are disclosed.
