As shown in FIG. 11, when the pull knob 422 is pulled backwards to the end, the inner slider 420 that slides inside the outer slider 410 also moves backward, and the second spring 421 is compressed to the maximum. In the closed state, the outer slider 410 moves rearward to further compress the first spring 414. At this time, the uppermost lancet 100 of the magazine 200 is pushed backward to the front end of the lancet input hole 411 of the outer slider 410 to prepare to be separated upward from the magazine 200, the coil of the magazine 200 It is separated upward by the spring force of the spring 210. The lancet 100 separated above the magazine 200 is introduced into the lancet input hole 411 of the external slider 410, and is then positioned inside the external slider 410 by the magnetic force of the magnet 412.

As shown in FIG. 12, when the loading knob 422 is pushed forward to closely contact the rear end of the main body 300, the inner slider 420 also slides toward the inner front of the outer slider 410 while the outer slider 410 is moved. The lancet 100 attached to the magnet 412 of the external slider 410 is pushed forward. At this time, the protective member 130 of the lancet 100 to move in the front of the outer slider 410 is caught by the ring spring 430 installed in front of the outer slider 410, the protective member 130 is a ring spring ( The attachment of the needle 120 protrudes forward from the protection member 130 while being slid to the rear of the needle 120 by the hook 430. When the inner slider 420 continues to move forward, the lancet 100 also moves forward, and overcomes the spring force of the ring spring 430 to open the ring spring 430 in the circumferential direction so that the slide moves forward. do. When the ring spring 430 encounters the fixing groove 140 of the lancet 100 moving forward, the ring spring 430 is fixed to the fixing groove 140 of the lancet 100 by the restoring force of the ring spring 430. As a result, the lancet 100 is fixed to the ring spring 430 installed at the front end of the outer slider 410.

At this time, the lancet 100 fixed to the ring spring 430 in front of the outer slider 410 is also fired toward the front of the main body 300, that is, the end cap 330, the protection member 130 of the lancet 100 At the same time the lancet 100 is stopped at the smaller end cap 330, the needle 120 protrudes forward of the end cap 330. In this case, the protruding length of the needle 120 may be adjusted by sliding back and forth from the front end of the main body 300 according to the rotation of the end cap 330. Since the needle 120 of the lancet 100 protrudes toward the front of the end cap 330, the blood is pierced by puncturing a body part such as a user's finger.

As shown in FIG. 14, the outer slider 410 and the lancet 100 moved forward by the pressing operation of the button 320 of the main body 300 are the restoring force of the first spring 414 of the outer slider 410. As you move backwards a little bit backwards. Accordingly, the needle 120 of the lancet 100 is maintained in a state that does not protrude forward of the end cap 330. At this time, since the blood collection is completed in the needle 120 of the lancet 100, the lancet 100 needs to be discharged from the lancing device 1 so as to bury blood in a strip or the like.

As shown in FIG. 15, when the loading knob 422 is pulled rearward in order to discharge the lancet 100 from which blood collection is completed, the inner slider 420 slides backward, and the outer slider 410 is moved. Move backward At this time, the discharge link 520 of the lancet discharge portion 500 is inserted into the lancet input hole 411 of the outer slider 410 in a state rising upward by the spring force of the discharge spring 510 is inserted into the lancet 100 To the rear end. When the outer slider 410 continues to move backward, the lancet 100 whose rear end is in contact with the discharge link 520 is peeled off from the ring spring 430 in front of the outer slider 410, and the fixing is released. Is discharged toward the lancet discharge groove 515. Meanwhile, as shown in FIG. 17, when the lancet locking unit 600 is locked, the uppermost lancet 100 of the magazine 200 is moved according to the rearward movement of the inner slider 420 and the outer slider 410. It may be continuously loaded into the outer slider 410. However, as shown in FIG. 18, when the lancet locking unit 600 is in the locked on state, the loading link of the lancet 100 is transferred because the locking link 620 fixes the uppermost lancet 100 of the magazine 200. Not done.

As shown in FIG. 16, when the lancet locking unit 600 is locked and the lancet 100 is continuously loaded and the inner slider 420 is moved forward, the lancet 100 is moved to the outer slider 430. It is kept fixed to the ring spring 430 installed at the front end. After that, the firing process may repeat the above process to continuously collect blood of the user.
