- the needle head may be formed in various forms integrally formed.
- the needle may be pressed from the same base material so that the needle body and the needle head are directly connected to each other without a needle neck, and may take a form made integrally.
- the shape, number, or location of the locking part for coupling with the carrier is not limited to the one shown and may be variously changed.
- the drawing shows that the needle body wing of the needle body is bent approximately vertically from the side of the needle body base, the angle between the needle body base and the needle body wing may be variously changed. Similarly, the angle between the needle head base and the needle head wing or the angle between the needle neck base and the needle neck wing may also be variously changed.
- a stopper for restraining the movement of the movable member is provided in the middle frame in a state where the elastic member providing a moving force to the movable member is elastically deformed
- the position of the stopper may be variously changed.
- the stopper may be installed in various positions of the applicator body other than the middle frame.
- the stopper may be provided with a moving unit to be engaged with the applicator body and released by an operating member.
- the base unit may take a configuration that simply supports the sensor unit so as not to be separated from the user's skin.
- a separate electronic unit capable of processing biometric information measured by the sensor unit and transmitting it to an external terminal may be detachably coupled to the base unit.
- a separate electronic unit may be coupled to the base unit to be electrically connected to the sensor unit after the sensor unit is coupled to the base unit.
- a body attachment unit including such a base unit may be used in combination with a separate electronic unit.
