Patent ID: 8460212

Claim:
A body fluid sampling unit comprising: a puncture mechanism comprising a needle possessing a sharp needle point at a distal end of the needle, and drive means for operating the needle to puncture a living body surface with the needle point; a body fluid sampling implement comprising an introducing section for introducing a body fluid flowing out from a puncture portion of the living body surface punctured with the needle point, a detecting section for detecting a predetermined component in the body fluid introduced through the introducing section, and a mounted section configured to be mounted to a component measuring device for measuring at least one of a quantity and a property of the predetermined component detected by the detecting section; a container comprising a mechanism containing section containing the puncture mechanism so that the needle point of the puncture mechanism is movable by the drive means, and a sampling implement containing section containing the body fluid sampling implement in a manner allowing the body fluid sampling implement to be removed from the sampling implement containing section; and the puncture mechanism is put into a state of being prepared to perform an operation of puncturing the living body surface by removal of the body fluid sampling implement from the sampling implement containing section.
