Abstract

The present disclosure relates to a body attachment device for continuous glucose monitoring and, more particularly, to a body attachment device for continuous glucose monitoring characterized in that as a user command for applying operating power of the body attachment device is inputted by an optical method or a touch method, operation of the body attachment device can be controlled by easily initiating application of battery power not only before the body attachment device is attached to the body but also after the body attachment device has been attached to the body. In addition, as the operation of the body attachment device is controlled by light or touch, it is possible to prevent erroneous operation of the body attachment device that occurs when a user touches, by mistake, a physical operation button formed in the body attachment device while using the body attachment device. Furthermore, the operating power can be stably provided.

First claim

1 . A body attachable apparatus for continuous blood glucose measurement continuously measuring a blood glucose value by being attached to a body of a user, the body attachable apparatus comprising:
a housing; a sensor unit, wherein a portion of the sensor unit is inserted to a body of the user to continuously measure a blood glucose of a user; a printed circuit board (PCB) disposed inside the housing and configured to be electrically connected to the sensor unit; a battery disposed inside the housing and configured to supply operation power needed for the PCB or the sensor unit; and a connection control unit configured to control electric connection of the battery and the PCB.

2 . The body attachable apparatus for continuous blood glucose measurement according to claim 1 , wherein the connection control unit comprises:
a control command input unit to which a connection command is inputted; a signal generating unit configured to generate a connection control signal based on the inputted connection command; and a switch unit electrically connecting between the battery and the PCB according the connection control signal.

3 . The body attachable apparatus for continuous blood glucose measurement according to claim 2 , wherein:
the control command input unit comprises a touch panel, and the signal generating unit is configured to, when the connection command of the user is inputted through the touch panel, generate the connection control signal.

4 . The body attachable apparatus for continuous blood glucose measurement according to claim 3 , wherein the signal generating unit is configured to compare a pattern of the connection command inputted through the touch panel with a reference set pattern, and when the pattern of the connection command is identical to the reference set pattern, generate the connection control signal.

5 . The body attachable apparatus for continuous blood glucose measurement according to claim 3 , wherein the connection control unit is configured to receive the connection control signal, and further comprises a second switch unit configured to block power of the battery supplied to the touch panel and the signal generating unit based on the connection control signal.

6 . The body attachable apparatus for continuous blood glucose measurement according to claim 2 , wherein:
the control command input unit comprises an optical receiver, and the signal generating unit is configured to, when the connection command of the user is inputted through the optical receiver, generate the connection control signal.

7 . The body attachable apparatus for continuous blood glucose measurement according to claim 6 , wherein the signal generating unit is configured to compare a pattern of the connection command inputted through the optical receiver with a reference set pattern, and when the pattern of the connection command is identical to the reference set pattern, generate the connection control signal.

8 . The body attachable apparatus for continuous blood glucose measurement according to claim 7 , wherein the signal generating unit is configured to generate the connection control signal by comparing a light frequency and pattern of the connection command inputted through the optical receiver with a light frequency and pattern of the reference set pattern.

9 . The body attachable apparatus for continuous blood glucose measurement according to claim 7 , wherein the connection control unit is configured to receive the connection control signal, and further comprises a second switch unit configured to block power of the battery supplied to the optical receiver and the signal generating unit based on the connection control signal.

10 . The body attachable apparatus for continuous blood glucose measurement according to claim 3 , wherein the signal generating unit is configured to search for a reference set pattern identical to a pattern of the inputted connection command, and generate the connection control signal corresponding to the searched reference set pattern.

11 . The body attachable apparatus for continuous blood glucose measurement according to claim 10 , wherein the connection control signal generated by the signal generating unit is a connection signal for electrically connecting between the battery and the PCB through the switch unit or a block signal for blocking electric connection between the battery and the PCB.

12 . The body attachable apparatus for continuous blood glucose measurement according to claim 3 , further comprising a blocking film blocking inputting the connection command to the control command input unit, wherein the blocking film is removably mounted to the control command input unit.

13 . The body attachable apparatus for continuous blood glucose measurement according to claim 6 , wherein the signal generating unit is configured to search for a reference set pattern identical to a pattern of the inputted connection command, and generate the connection control signal corresponding to the searched reference set pattern.

14 . The body attachable apparatus for continuous blood glucose measurement according to claim 6 , further comprising a blocking film blocking inputting the connection command to the control command input unit, wherein the blocking film is removably mounted to the control command input unit.
