The working principle of the blood glucose meter is as follows: after the test paper containing blood is inserted into a glucometer, the blood glucose concentration is converted into an analog electric signal, and the blood glucose value is obtained after the test by the blood glucose test module.
During the working process of the blood glucose test module, certain heat can be generated, so that the temperature inside the blood glucose meter is increased. And the test result of the thermistor 1 at the excessively high temperature has errors, so that the environmental temperature measured by the thermistor 1 is inconsistent with the actual environmental temperature, and the blood glucose meter cannot measure the accurate blood glucose value. In order to reduce the influence of the thermistor 1 due to the temperature of the blood glucose test module, a first heat insulating sheet 3 is provided on one side of the blood glucose test module. Through first heat insulating sheet 3, insulate against heat to the heat that blood sugar test module produced, avoid the heat to conduct for thermistor 1 because of the heat transfer, increase thermistor 1's measurement accuracy.
