A lancet device and a method thereof are provided to inject blood to a blood chamber through an injection hole of a diagnosis and blood analysis apparatus like a DBD(Digital Bio Disc) or a lab of a chip, after extracting the blood from a skin of a mammal, by a vacuum or capillary tube. A handle(1) provides driving by a thumb of an operator. A piston(2) is connected to the handle and proceeds by the pressure of the handle. A cylinder(3) includes a plurality of springs and a plunger inducing trigger operation by being connected to the piston. A needle(7) penetrates into the skin by the trigger operation and then returns. A vacuum cap(4) and a piston ring draw out the skin by the vacuum. A lancet cap(5) has the needle and a lancet chamber or a capillary tube chamber(8) storing the blood temporarily. And a blood exhaustion hole exhausts the blood stored in the lancet chamber or the capillary chamber to the outside by the pressing of the handle. |
