Abstract: A body fluid collecting device includes a tip with a puncture needle and a front end opening at the front end portion thereof for allowing the puncture needle to pass therethrough. The device additionally includes a device body, having a contact part for fitting skin thereto, a tip mounting part having a storage space formed therein capable of storing the tip, a pump for depressurizing the inside of the storage space, and a movable means. The movable means is capable of moving the front end portion of the tip mounting part along a longitudinal direction of the puncture needle, and within a specified range, when the storage space is depressurized by the pump under a condition in which the tip is stored in the storage space, the skin is fitted to the contact part, and the front end opening is sealed.

Abstract: A specimen collection tip for collecting a specimen includes a base portion, a slender tube extending from one face of the base portion, a plurality of elastically deformable mounting claws extending from the opposite face of the base portion, and a test paper is set in place on the opposite face of the base portion. The base portion is generally in the shape of a flat disc and has a pedestal part for supporting and fixing the test paper. The opposite face of the base portion also includes a flange part formed at the outer peripheral side of the base portion. The lower face of the flange part is formed in a generally flat plane. When the tip is inserted into a tip receiving part of an analyte measuring device, the lower face of the flange part contacts the leading end of the tip receiving part to fix the position of the tip with respect to the tip receiving part.
