The first inclined surface 240 formed on the bottom surface of the push member 200 and the second inclined surface 331 formed on the blade piece 330 are in contact with each other and the lancet holder 320, As shown in FIG.

When the end cap 122 of the end cap 120 is inserted into the body 110 of the case and the end cap 120 is pressed against the end cap 120, Assembling is completed by being fitted into the coupling groove 113 formed on the inner wall of the casing 110.

The operation of the blood collecting apparatus assembled as described above will be described as follows.

FIG. 4 is an operational view showing a state before the push member of the blood-drawing device is pressed, FIG. 5 is an operation view showing a state in which the lancet is pressed by the pressure of the first inclined surface when the push member of the blood- 6 is an operation diagram showing a state in which the lancet portion is fired at a moment when the second inclined surface of the righthand portion slides on the first inclined surface of the push member and the needle protrudes forward of the push member.

As shown in FIG. 3, the needle protection cap 311 surrounding the needle 310 is cut and removed when the cut-out piece 312 of the needle protection cap 311 protruding from the distal end of the blood vessel is twisted. It becomes the same state. 4, when the tip of the push member 200 protruding outward from the case is pressed against the skin, as shown in FIG. 5, the guide protrusion 220 of the push member is inserted into the guide portion formed on the inner wall of the case 110 The lancet portion 300 is lowered along the both guide bars 112 while pressing the lancet 330 of the lancet portion which is in contact with the lower portion of the guide protrusion 220 of the push member. The descent of the lancet portion 300 compresses the elastic spring 340 that elastically supports the lancet holder 320.
