Claims

[Scope of Claim for Utility Model Registration] 1. In a blood sampling lancet device in which a lancet is movable forward and backward relative to a casing and a blood sampling operation is performed by moving the lancet forward and backward, an engagement provided integrally with the lancet. a rotating body formed with an engaging portion that is always biased to rotate in one direction by the biasing means and that is always engaged with the engaging portion to move the lancet forward and backward in accordance with the rotating motion; A blood sampling lancet device comprising a state selection means for selecting a state in which the rotating body is prevented from rotating in the biasing direction and a state in which the rotating body is allowed to rotate, and a double-movement lever that moves the rotating body back. . 2. The blood sampling lancet device according to claim 1, wherein the engaging portion provided integrally with the lancet is an engaging pin, and the engaging portion formed on the rotating body is a cam groove. 3. The blood sampling lancet device according to claim 1, wherein the engaging portion provided integrally with the lancet is a cam groove, and the engaging portion formed on the rotating body is an engaging pin. 4. Claim 1 of the above-mentioned utility model registration, in which the cam groove moves the lancet most forward when engaged with the engaging pin at the center, and moves the lancet most backward when engaged with the engaging pin at both ends. The blood sampling lancet device according to any one of Items 1 to 3. 5 The cam grooves are symmetrical to each other with the center as the boundary,
The blood sampling lancet device according to claim 4, wherein the lancet device extends in a straight line. 6 The state selection means includes a rotating lever that engages with an engaging portion formed at a predetermined position of the rotating body to prevent rotation in the biasing direction, and a rotating lever that engages with the engaging portion. The blood sampling lancet device according to claim 1, further comprising a biasing means for biasing the lancet to rotate in a direction of rotation. 5. The blood sampling lancet device according to claim 1, wherein the casing has a mark member located in front of the tip of the lancet in the retracted state. 6. The blood sampling lancet device according to claim 5, wherein the mark member is movable forward and backward, and in the retracted state is located on the rear side of the tip of the lancet in the forward state.
