PROBLEM TO BE SOLVED: To provide a body fluid sampling device satisfying at least the following required performances: (1) allowing a subject to actively and independently control pain in needling by reducing a psychological barrier to the needling and (2) conveying the body fluid sampled from the body by a needling means to a device inside in a simple constitution without providing special suction means and mechanism in the device side.SOLUTION: A body fluid sampling device is constituted by defining a part of a wall of a housing as a pressing part to a body fluid sampling surface of a living body and disposing the needling means in a position corresponding to the pressing part inside the housing and, when the pressing part is pressed by the body fluid sampling surface such as a fingertip, the needling means provided corresponding to the pressing part needles through the pressing part and further the body fluid sampling surface to exude the body fluid such as the blood. As the body fluid sampling surface is then separated from the pressing part, the body fluid is efficiently introduced into the housing due to the negative pressure produced in the internal region of the housing by the elastic movement of the pressing part.COPYRIGHT: (C)2007,JPO&INPIT【課題】少なくとも以下の要求性能を満たす体液採取装置を提供すること。(1)穿刺に対する心理的障壁が低減されており、穿刺に伴う痛みの、被験者による能動的かつ自主的制御が可能である。(2)穿刺手段によって体内から取り出された体液を装置側に特別な吸引手段や吸引機構を設けることなく簡便な構成で装置内に搬送可能である。【解決手段】筺体の壁の一部を生体の体液採取面への押圧部とし、筺体内の押圧部に対応する位置に穿刺手段を配置して体液採取装置を構成し、押圧部を指先などの体液採取面によって押圧した際に、押圧部に対応して設けられた穿刺手段により押圧部を貫通するとともに体液採取面を刺通して血液等の体液を滲出させ、押圧部から体液採取面を離す動作とともの筺体内部領域に発生する負圧により効率よく体液を筺体内へ導入する。【選択図】図1
