Handheld Diabetes Management Device With Bolus Calculator

A method for determining a correction meal rise value, the correction meal rise value being indicative of an amount the bG level of the patient can increase with respect to a target bG value without requiring a correction bolus, the method comprising:

• maintaining a plurality of active advice history records, each of the plurality of active advice history records having been generated during a predetermined time period relative to a current time, and each of the plurality of active advice history records identifying data relating to a bG influencing event and including a time corresponding to the bG influencing event;
• identifying, at one or more processors, a specific active advice history record of the plurality of active advice history records, wherein the events defined in the specific active advice history record include a bolus being associated with a carbohydrate intake event where the carbohydrate intake is greater than a predetermined threshold and further including an indication that insulin was administered to the patient in response to the bolus and correspond to a time that is more recent to a current time than other active advice history records in the plurality of active advice history records defining events that include a meal bolus and a confirmation of insulin;
• determining, at the one or more processors, an amount of time that has lapsed since the time corresponding to the specific active advice history record;
• comparing, at the one or more processors, the amount of time to a predetermined time threshold;
• setting, at the one or more processors, the correction meal rise value equal to a full meal rise value as defined in the specific active advice history record when the amount of time is less than the predetermined time threshold;
• and
• setting, at the one or more processors, the correction meal rise value equal to an adjusted meal rise value based on the amount of time and the full meal rise value when the amount of time is greater than the predetermined time threshold.

A diabetes management device configured to determine an allowable amount of blood glucose (bG) of a patient, the allowable amount of blood glucose being used to calculate a bolus recommendation for a patient, the device comprising:

• an advice history records database that stores a plurality of active advice history records, each of the plurality of active advice history records having been generated during a predetermined time period relative to a current time, and each of the plurality of active advice history records identifying data relating to one or more bG influencing events and including a time corresponding to the one or more bG influencing events;
• a computer-readable medium storing computer-readable instructions;
• one or more processors configured to execute the computer-readable instructions, the computer-readable instructions, when executed by the one or more processors, causing the one or more processors to:
• identifying a specific active advice history record of the plurality of active advice history records, wherein the events defined in the specific active advice history record include a bolus being associated with a carbohydrate intake event where the carbohydrate intake is greater than a predetermined threshold and further including an indication that insulin was administered to the patient in response to the bolus and correspond to a time that is more recent to a current time than other active advice history records in the plurality of active advice history records defining events that include a meal bolus and a confirmation of insulin;
• determining an amount of time that has lapsed since the time corresponding to the specific active advice history record;
• comparing the amount of time to a predetermined time threshold;
• setting the correction meal rise value equal to a full meal rise value as defined in the specific active advice history record when the amount of time is less than the predetermined time threshold;
• and
• setting the correction meal rise value equal to an adjusted meal rise value based on the amount of time and the full meal rise value when the amount of time is greater than the predetermined time threshold.
