A combination of a body fluid component measuring apparatus and a chip adapted to be mounted thereto. The chip comprises a chip housing, a puncture needle and a strip of test paper disposed on said chip housing. The chip housing possesses a contact portion at a tip side thereof, and said contact portion internally possesses a tip opening. The body fluid component measuring apparatus comprises a touch portion to which an epidermis to be punctured is touched, a housing space for holding the chip, puncturing means for operating said puncture needle when the chip is mounted to said apparatus so as to puncture the epidermis touched to the touch portion, evacuating means for evacuating a puncture site of the epidermis to be punctured by said puncture needle as well as said housing space, measuring means for measuring an amount of a specific component of a body fluid sampled from the puncture site and diffused in said test paper, body fluid sampling detecting means for detecting the sampling of the body fluid and evacuation releasing means for releasing or relieving the evacuation state of at least said housing space. When the sampling of the body fluid is detected by the body fluid sampling detecting means, the evacuation state of at least said housing space is released or relieved, and then the amount of the specific component in the sampled body fluid is measured by said measuring means. |
