Body attachable unit for continuous blood glucose measurement
The present invention relates to a body attachment unit for continuous blood glucose monitoring, in which a body attachment unit is manufactured so as to be assembled in an applicator, thereby minimizing additional work and allowing attachment of the body attachment unit to a body simply by operation of the applicator. In particular, a wireless communication chip is provided in the body attachment unit to enable communication with an external terminal, thereby enabling simple and convenient use without additional work of connecting a separate transmitter, and allowing easier maintenance. In addition, activation occurs by a user's operation after the body attachment unit is attached to the body, such that an activation start time can be adjusted to a time appropriate to the user's needs, and activation occurs in a stabilized state, thereby allowing more accurate blood glucose monitoring.
1. A body attachable unit for continuous glucose measurement, the body attachable unit configured to be insertedly attachable to a body by an applicator for the continuous glucose measurement, the body attachable unit comprising:
a housing, wherein a bottom surface of the housing is to contact a skin;
a printed circuit board (PCB) disposed inside the housing;
a sensor unit installed to the housing, wherein one end portion of the sensor unit outwardly protrudes from the bottom surface of the housing to be inserted into the body when the housing contacts the skin, and an other end portion of the sensor unit is configured to be contactable with a plurality of electric contact points of the PCB protruding toward the other end portion of the sensor unit and disposed away from the other end portion of the sensor unit; and
a pressurizing operation module configured to operate according to manipulation of a user so that the pressurizing operation module applies pressure to the other end portion of the sensor unit to be contacted to the electric contact points of the PCB,
wherein the electric contact points of the PCB protruding toward the other end portion of the sensor unit and disposed away from the other end portion of the sensor unit are configured to be contactable with the other end portion of the sensor unit by the manipulation of the user to the pressurizing operation module applying the pressure to the other end portion of the sensor unit, and at least one of the electric contact points has a higher protruding height than another or others of the electric contact points, and
wherein the pressurizing operation module is configured to pressurize the other end portion of the sensor unit to move more than a distance between the other end portion of the sensor unit and one of the electric contact points having a lowest protruding height.
2. The body attachable unit for the continuous glucose measurement of claim 1 , wherein the sensor unit is configured to initiate operation when all of the electric contact points of the PCB contact the other end portion of the sensor unit.
3. The body attachable unit for the continuous glucose measurement of claim 2 , wherein a sensor support configured to support the other end portion of the sensor unit to be spaced apart from the electric contact points of the PCB is disposed in the housing.
4. The body attachable unit for the continuous glucose measurement of claim 3 , wherein a board support configured to support the PCB to fix a position of the PCB is disposed inside the housing.
5. The body attachable unit for the continuous glucose measurement of claim 3 , wherein the electric contact points of the PCB elastically protrude from the PCB and are configured to be elastically transformable.
6. The body attachable unit for the continuous glucose measurement of claim 1 , wherein the other end portion of the sensor unit has at least one cut section configured to be transformable by being pressurized by the pressurizing operation module to be contacted to the electric contact points of the PCB.
