PROBLEM TO BE SOLVED: To provide a method for obtaining a body fluid sample through a minimally invasive skin without actual pain by piercing an area especially having less sensitivity of the skin. SOLUTION: A body sample such as blood or an interstitial fluid is obtained from a body by suitably incising a part of the user's skin in the area except a fingertip to form an incised part. After a needle 42 is removed from the incised part, force is applied to press down the skin by a way for forming a ring of a pressed-down body tissue in relation to the surrounding of the incised part, the incised part is swelled to open a side part of the incised part, so that the body fluid is pressed out through an opening of the incised part. A stimulator member 64 is installed to an end part of a lancet carrying a housing 40 to apply the force. The stimulator member 64 is movable relatively to the housing 40, and is heated or vibrated to promote movement of the body fluid. |
