The invention discloses a method and equipment for calculating the injection
dose of a periinsulin preparation. The method comprises the following steps: acquiring a
single injection pharmacokinetic model of the periinsulin preparation, historical injection information of a patient using the periinsulin preparation, a fasting blood glucose value monitored during the period of using the periinsulin preparation by the patient and a
dose estimated value of the injection; according to the acquired
single injection pharmacokinetic model, the historical injection information, the fasting blood glucose value and the
dose estimation value, predicting fasting blood glucose of the patient in a next week after the patient injects the periinsulin preparation according to the
dose estimation value; according to whether the fasting blood glucose of the next week is within the fasting blood glucose
target range of the patient or not, whether the
dose estimation value needs to be adjusted or not is judged, and the
dose estimation value is adjusted based on the judgment result so that the adjusted injection dose
estimation value can meet the requirement. The injection dosage can enable a patient to reach a
steady state as soon as possible, and the injection dosage can be compatible with occasionally irregular injection
modes.
