Abstract

The present invention is made to provide a safe and efficient blood glucose measuring device capable of collectively performing blood glucose measurement process and collectively performing insulin administration process on many patients, while ruling out the risk of misidentification and misprescription among the patients. When having read a patient ID with a patient ID reading section, a control section identifies a record of the patient of a measurement/administration results table. The control section does not perform blood glucose measurement on the patient of the identified record which shows that a blood glucose measurement flag is “true” and an insulin administration confirmation flag is “false”, and displays an insulin dosage on a display unit with respect to the patient by referring to a prescription information table based on the blood glucose level has been measured. The control section does not display the insulin dosage on the display unit again for the patient whose record is identified which shows that the insulin administration confirmation flag is “true”.
