Abstract: The present disclosure relates to a method for providing guidance on a use period of a sensor and, more specifically, to a method for providing guidance on a use period of a sensor, which accurately provides guidance to a user about a use period of a sensor by calculating the number of sensors possessed by the user and the total use period from the use period of each sensor so as to determine whether the remaining use period has arrived at an order guidance period or to determine whether the remaining use period of the last sensor has arrived at the order guidance period, on the basis of a sensor usage history of the user, and enable the user to order sensors on the basis of the guidance.

Abstract: The present disclosure relates to a notification method of a continuous glucose monitoring system. A notification method of a continuous glucose monitoring system, according to one embodiment of the present invention, may comprise the steps of: performing a communication connection between a body attachment unit and a communication terminal for the communication terminal to receive blood glucose data measured from the body attachment unit which is attached to a human body and continuously measures blood glucose; transmitting information on the body attachment unit from the body attachment unit to the communication terminal and calculating a remaining use period of the body attachment unit; and generating, in the communication terminal, a notification on the remaining use period of the body attachment unit.

Abstract: The present disclosure relates to a communication connection method for a continuous glucose monitoring system. A communication connection method for a continuous glucose monitoring system according to an embodiment of the present disclosure may comprise: a step in which, in order to connect communication between a communication terminal and a sensor transmitter attached to a human body so as to continuously monitor biometric information of the human body, the communication terminal receives information of the sensor transmitter from the sensor transmitter; a step of determining, on the basis of the received information, whether the sensor transmitter is a new sensor transmitter or an already used sensor transmitter; and a step in which, when the sensor transmitter is an already used transmitter, communication connection is controlled on the basis of use information of the already used sensor transmitter.
