Abstract

The present disclosure relates to a continuous glucose monitoring device, in which a body attachment unit is manufactured so as to be assembled in an applicator, thereby minimizing additional work for a user in attaching the body attachment unit to a body, and allowing attachment of the body attachment unit to the 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, the continuous glucose monitoring device is activated 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 the continuous glucose monitoring device can be activated in a stabilized state, and thereby can monitor blood glucose more accurately.

Claims (42)

1. A continuous glucose measurement apparatus, comprising:

a body attachable unit configured to be insertedly attachable to a body; and

an applicator in which the body attachable unit is coupled,

wherein the body attachable unit is inserted to an inside of the applicator so that the body attachable unit and the applicator are assembled,

wherein the body attachable unit comprises a sensor unit, wherein one end portion of the sensor unit is insertable into the body, and a wireless communication chip configured to wireless communicate with an external terminal,

wherein the applicator comprises:

a main case, wherein a pressure button is installed at one side of the main case;

a plunger body configured to be fixed at a first location inside the main case, and be released from fixation at the first location and linearly move to a second location in an outward discharge direction according to manipulation of the pressure button; and

a plunger elastic spring configured to apply an elastic force to the plunger body so that the plunger body linearly moves from the first location to the second location,

wherein the body attachable unit is coupled with one end of the plunger body and the body attachable unit is configured to be movable together with the plunger body from the first location to the second location, and

wherein a protection cap is separably coupled to the applicator to block exposure of the body attachable unit from an outside of the applicator in a state that the body attachable unit is inserted into the inside of the applicator.

2. The continuous glucose measurement apparatus of claim 1 , wherein the body attachable unit is configured to initiate operation of the sensor unit and the wireless communication chip by a switch configured to be manipulated by a user.

3. The continuous glucose measurement apparatus of claim 1 , wherein a shooting plate configured to be movable according to the manipulation of the pressure button is coupled in the main case, and the plunger body is configured to be fixed at the first location by being interlocked with the shooting plate, and be released from interlock with the shooting plate according to movement of the shooting plate.

4. The continuous glucose measurement apparatus of claim 3 , wherein the main case comprises;

an outer case, wherein the pressure button is installed to one side of the outer case;

an inner case coupled to an inside of the outer case, the inner case configured to guide a linear movement path of the plunger body; and

the shooting plate is configured to move by being supported by the inner case.

5. The continuous glucose measurement apparatus of claim 4 , wherein the outer case comprises a hanging raised part positioned at a portion of the outer case where the pressure button is disposed, and

the pressure button is slidably mounted along an outer surface of the outer case so that a mode is changeable between a safe mode, in which the pressure button is interlocked with the hanging raised part to prevent pressurizing movement caused by pressurizing manipulation of a user, and a pressure standby mode, in which interlock with the hanging raised part is released to be capable of performing the pressurizing movement caused by the pressurizing manipulation of the user.

6. The continuous glucose measurement apparatus of claim 1 , wherein the body attachable unit comprises:

a housing configured to be outwardly discharged by the applicator so that a bottom surface of the housing is attachable to the body, wherein the sensor unit is included in the housing in a structure that the one end portion of the sensor unit outwardly protrudes from the housing, and the wireless communication chip is included in the housing; and

a needle unit configured to be separably coupled to the housing, covering the one end portion of the sensor unit so that the needle unit is movable together with the sensor unit and the one end portion of the sensor unit is inserted into the body according to outwardly discharging movement of the housing, and

wherein the applicator comprises a needle extracting unit configured to extract and remove the needle unit from the body by moving the needle unit toward the first location when movement of the plunger body from the first location to the second location is completed.

7. The continuous glucose measurement apparatus of claim 1 , wherein

an adhesive tape and a release paper are attached to a surface of the body attachable unit which is to be contacted with the body so that the body attachable unit is attachable to the body, and

the release paper is configured to be separated and removed from the adhesive tape together with the protection cap when the protection cap is separated from the applicator.

8. The continuous glucose measurement apparatus of claim 1 , wherein the main case comprises a return prevention unit configured to block returning movement of the plunger body returning toward the first location after the plunger body is moved to the second location.

9. The continuous glucose measurement apparatus of claim 8 , wherein the return prevention unit comprises:

an interlocking body formed at one side of the plunger body; and

a return prevention hook formed at the inner case to prevent the returning movement of the plunger body by being interlocked with the interlocking body when movement of the plunger body from the first location to the second location is completed, wherein an elastic restoration force causes the return prevention hook to be interlocked with the interlocking body.

10. The continuous glucose measurement apparatus of claim 1 , wherein the plunger body is configured so that an end of the plunger body further protrudes than an end of the main case in a state that the plunger body is moved from the first location to the second location according to the manipulation of the pressure button.

11. A continuous glucose measurement apparatus, comprising:

a body attachable unit configured to be insertedly attachable to a body; and

an applicator in which the body attachable unit is coupled,

wherein the body attachable unit is inserted to an inside of the applicator so that the body attachable unit and the applicator are assembled,

wherein the body attachable unit comprises a sensor unit, wherein one end portion of the sensor unit is insertable into the body, and a wireless communication chip configured to wireless communicate with an external terminal,

wherein the applicator comprises:

a main case;

a plunger body configured to be fixed at a first location inside the main case, and be released from fixation at the first location and linearly move to a second location in an outward discharge direction,

wherein the body attachable unit is coupled with one end of the plunger body and the body attachable unit is configured to be movable together with the plunger body from the first location to the second location,

wherein the body attachable unit is configured so that an end of the body attachable unit further protrudes than the end of the main case in a state that the body attachable unit is moved to the second location together with the plunger body, and

wherein a protection cap is separably coupled to the applicator to block exposure of the body attachable unit from an outside of the applicator in a state that the body attachable unit is inserted into the inside of the applicator.
