< Topic > Bias of the expansion tonnage in the suffering operation body which it occurs with the difference of the region which receives the operation from the subject is lost, by the fact that the expansion tonnage of the suffering operation body is made to equalize, the living body information which is stabilized the collection possible living body data gathering device is offered. Solutions The living body data gathering device 1 collecting the living body information of the subject, the specified fluid to possess the containment possible internal space, receiving the external operation from the subject and the suffering operation body the pressure detection section 3 where detects the fluctuation of 2 where the internal pressure fluctuates and the internal pressure and, have, suffering operation body 2 run facilities to be done in rectilinear condition, the multiple electrolysis cells the concatenated section 22a which makes the electrolysis cell concatenate which it adjoins 21a which possess the containment possible internal space - 21e, - 22d and, to have the respective fluid, as for concatenated section 22a - 22d, the electrolysis cell 21a - 21eThe fluid inside the electrolysis cell where the cross section area is narrower than the cross section area which parallels to aforementioned rectilinear, is adjacent the converging section which is circulation possible (the part where seal section 221 is excluded) is made the configuration which it possesses. < Choice figure > Drawing 1【課題】 被験者からの作用を受ける部位の違いによって生じる被作用体における膨張量の片寄りをなくし、被作用体の膨張量を均一化させることで、安定した生体情報を収集可能な生体情報収集装置を提供する。【解決手段】 被験者の生体情報を収集する生体情報収集装置1であって、所定の流体を保持可能な内部空間を有し、被験者からの外的な作用を受けて内圧が変動する被作用体2と、内圧の変動を検知する圧力検知部3と、を備え、被作用体2は、直線状に連設され、それぞれ流体を保持可能な内部空間を有する複数のセル21a~21eと、隣接するセル同士を連結させる連結部22a~22dと、を備え、連結部22a~22dは、セル21a~21eの前記直線方向に沿った断面積よりも断面積が狭く、隣り合うセル内の流体が流通可能な絞り部(シール部221を除く部分)を有する構成としてある。【選択図】 図1
