PROBLEM TO BE SOLVED: To provide a hemodynamometry device capable of measuring a blood pressure highly accurately for a short time period without troubling the user.SOLUTION: A hemodynamometry device comprises: a pressing face 6b formed with an element row composed of a plurality of pressure sensors 6a and 7a arranged in one direction an air bag 2 for pushing the pressing face 6b onto a living body region containing a radial artery T while having one direction intersecting with the extending direction of a radial artery T an air bag drive part 11 for controlling a pressing force by the air bag 2 a rotating drive part 10 for driving the pressing face 6b on at least one of an axis X and an axis Y orthogonal in the pressing direction by the air bag 2 and a control part 12 for performing the rotational control of the pressing face 6b on the basis of pressure pulse wave which is detected by the pressure sensors 6a and 7a in the process where the pressing force increases, to detect a blood pressure value in the radial artery T on the basis of the pressure pulse wave which is detected by the pressure sensors 6a and 7a after the rotation control in a process where the pressing force decreases.SELECTED DRAWING: Figure 6COPYRIGHT: (C)2016,JPO&INPIT【課題】利用者に煩わしい思いをさせることなく、短時間で高精度に血圧を測定することのできる血圧測定装置を提供する。【解決手段】血圧測定装置は、一方向に並ぶ複数の圧力センサ6a,7aからなる素子列が形成された押圧面6bと、一方向が橈骨動脈Tの伸びる方向と交差する状態で押圧面6bを橈骨動脈Tを含む生体部位に押圧するための空気袋2と、空気袋2による押圧力を制御する空気袋駆動部11と、空気袋2による押圧方向に直交する軸Xと軸Yの少なくとも一方を中心に押圧面6bを回転駆動する回転駆動部10と、押圧力が増加する過程で圧力センサ6a,7aにより検出された圧脈波に基づいて押圧面6bの回転制御を行い、回転制御後に、押圧力が減少する過程で圧力センサ6a,7aにより検出される圧脈波に基づいて橈骨動脈T内の血圧値を算出する制御部12と、を備える。【選択図】図6
