BLOOD GLUCOSE METER AND BLOOD GLUCOSE LEVEL MEASUREMENT METHOD

摘要

Disclosed are a blood glucose meter and a blood glucose level measurement method which make it possible to measure blood glucose levels in an appropriate environment by reliably detecting changes in the ambient temperature of the blood glucose meter. An internal temperature thermistor for measuring the temperature inside the housing of the blood glucose meter is disposed inside the housing of the blood glucose meter, and an external air temperature thermistor for measuring external air temperature formed from a component having a low thermal capacity is disposed away from the center of the housing of the blood glucose meter. A blood glucose meter microcomputer evaluates whether or not temperature fluctuations are within the permissible range on the basis of the difference between the two temperatures. The blood glucose meter microcomputer temporarily halts glucose level measurement processing until the temperature fluctuations return to within the permissible range if the permissible range is exceeded immediately prior to blood glucose level measurement, and discontinues processing if the permissible range is exceeded during blood glucose level measurement.
