(57) [Summary] [Problem] A puncture, collection of body fluid (blood), and measurement can be continuously performed with a simple operation, and the body fluid is not scattered. A component measuring device includes a main body and a main body. , Puncturing means 3 for puncturing the surface of the living body with puncturing needle 12, and decompression means 5 for setting the puncture site of puncturing needle 12 in a reduced pressure state. A link mechanism 6, a decompression releasing means 7 for releasing the decompressed state by the decompression means 5, an operating means 8, and a measuring means for measuring a predetermined component such as glucose in a sample (blood). I have. When the lid 27 is opened, the depressurizing plunger 50 is pressed in the distal direction by the operation of the link mechanism 6, the second locking portion 54 is locked to the claw 82, and the spaces 262, 2 61 is now ready for decompression. |
