1. A method comprising:

  • receiving a blood glucose measurement of a patient at a data processing device from a glucometer in communication with the data processing device;

    obtaining, by the data processing device, a blood glucose time associated with measuring the blood glucose measurement;

    receiving patient information at the data processing device from a non-transitory computer-readable medium in communication with the data processing device, the patient information comprising recommended equal-boluses of insulin for administration to the patient at sequential time intervals throughout a day, the number of sequential time intervals comprising;

    six sequential time intervals, each spaced four hours apart;

    orfour sequential time intervals, each spaced six hours apart;

    determining, by the data processing device, which of the sequential time intervals includes the blood glucose time for the blood glucose measurement of the patient;

    determining, by the data processing device, for a given blood glucose time within a first sequential time interval of the four sequential time intervals or a second sequential time interval of the six sequential time intervals, a given blood glucose measurement that is within one of a plurality of target ranges of values, the plurality of target ranges of values comprising;

    a first target range of values including blood glucose values less than a first configurable constant;

    a second target range of values including blood glucose values greater than or equal to the first configurable constant and less than a low target blood glucose value of a target blood glucose range for the patient;

    a third target range of values including blood glucose values greater than or equal to the low target blood glucose value and less than a high target blood glucose value of the target blood glucose range;

    a fourth target range of values including blood glucose values greater than or equal to the high target blood glucose value and less than a second configurable constant;

    a fifth target range of values including blood glucose values greater than or equal to the second configurable constant and less than a third configurable constant; and

    a sixth target range of values including blood glucose values greater than or equal to the third configurable constant;

    determining, by the data processing device, an adjustment factor for adjusting a value of recommended equal-boluses to the patient based on the corresponding target range of values and the given blood glucose measurement; and

    retrieving, by the data processing device, a previous day'"'"'s value of recommended equal-boluses;

    determining, by the data processing device, a new value of recommended equal-boluses by multiplying the adjustment factor times the previous day'"'"'s value of recommended equal-boluses, wherein the new value of recommended equal-boluses corresponds to an insulin dose of rapid-acting insulin or regular insulin to be administered to the patient at scheduled blood glucose measurements;

    setting, by the data processing device, a timer for a next blood glucose measurement based on the sequential time intervals;

    determining, by the data processing device, a correction bolus based on the blood glucose time by calculating;


    CBx=(BG−

    BGTarget)/CF;

    wherein CB is the correction bolus, BG is the blood glucose measurement, BGTarget is a target blood glucose value of the patient, and CF is a correction factor; and

    administering the new value of recommended equal-boluses and the correction bolus to the patient by transmitting the new value of recommended equal-boluses and the correction insulin dose from the data processing device to a remote administration device comprising a doser configured to;

    automatically set or dial in and administer a first number of units of insulin corresponding to the new value of the recommended equal-boluses to the patient at each of the sequential time intervals; and

    automatically set or dial in and administer a second number of units of insulin corresponding to the correction bolus to the patient.
