Dynamic glucose meters are generally recommended to be used for 14 days, which is mainly limited by the presence of the enzyme that plays a major role in sensing. During the use of the glucose meter, the enzyme on the glucose meter sensor will be gradually metabolized in the body, which will cause the glucose meter to lose its original sensing effect. The sensing enzyme’s time of action is generally around 14 days, so it is recommended that it be replaced after 14 days of use. For people with long-term high blood glucose or diabetes, the use of dynamic blood glucose meter can accurately monitor the fluctuation of blood glucose, thus providing a more accurate blood glucose curve, to help patients make timely adjustments of hypoglycemic drugs and monitor blood glucose at any time. In the use of dynamic glucose meter, should follow the doctor’s instructions for the correct glucose meter wear operation, and in the use and wear the process at any time to do a good job of local skin cleaning and drying care, can effectively ensure that the body surface clean and healthy, but also can be appropriate to extend the service life of dynamic glucose meter. If there is any discomfort, consult a doctor in time.
