A battery is built in the sensor module and a separate transmitter is connected to the sensor module so as to receive power supply from the sensor module and be continuously used semi-permanently, thereby making the assembly economical. The sensor module and the applicator are used disposables, thereby allowing accurate and safe use and convenient maintenance. ## Claims ### Claim 1 A sensor applicator assembly for a continuous blood glucose monitor, wherein the sensor applicator assembly is assembled as a single unitary product in a state in which a sensor module configured to measure blood glucose is inserted in an inside of an applicator, and the sensor module is configured to be outwardly ejected to be attached to a body according to operation of the applicator, wherein: a separate protective cap is detachably coupled to the applicator to block the sensor module from being exposed externally in the state in which the sensor module is inserted in the inside of the applicator, a locking member is included in the protective cap to prevent the protective cap from being separated from the applicator in a state that the protective cap is coupled to the applicator, and the locking member is configured to be locked or unlocked according to manipulation of a user, wherein the protective cap comprises: an outer cover covering an outer circumferential surface of the applicator and coupled to an end portion of the applicator; an extension extending from one end portion of the outer cover in a direction of an inner center of the applicator; and an inner support extending upward from one end portion of the extension to be inserted in the inside of the applicator. ### Claim 2 (depends on 1) The sensor applicator assembly for the continuous blood glucose monitor according to claim 1, wherein the locking member comprises: a locking lever rotatably coupled to one side of the protective cap; and a locking catch protrusion formed at one end portion of the locking lever to be engagedly coupled to the applicator. ### Claim 3 (depends on 2) The sensor applicator assembly for the continuous blood glucose monitor according to claim 2, wherein a locking catch recess is formed at one side of an outer circumferential surface of the applicator so that the locking catch protrusion is engagedly coupled to the locking catch recess. ### Claim 4 (depends on 3) The sensor applicator assembly for the continuous blood glucose monitor according to claim 3, wherein the locking lever is elastically supported in a direction in which the locking catch protrusion is engagedly coupled to the locking catch recess. ### Claim 5 (depends on 4) The sensor applicator assembly for the continuous blood glucose monitor according to claim 4, wherein an elastic hinge shaft is formed at a middle portion of the locking lever, and the locking lever is configured to elastically rotate about the elastic hinge shaft so that the locking catch protrusion is engagedly coupled to the locking catch recess. ### Claim 6 (depends on 2) The sensor applicator assembly for the continuous blood glucose monitor according to claim 2, wherein the locking lever is rotatably formed at the outer cover.
