PROBLEM TO BE SOLVED: To provide an electronic sphygmomanometer capable of closely attaching a cuff just by inserting an upper arm and easily and accurately measuring a blood pressure.SOLUTION: The electronic sphygmomanometer measures a blood pressure by inserting the upper arm to the insertion part of a cuff part 2 and closely attaching an air bag 14 to the upper arm. The cuff part includes a backing material 15 forming an elastic belt body in a spiral shape and the air bag 14 disposed on the entire periphery on the inner side of the backing material. A wire 12 is wound around the outer periphery of the backing material in order to closely attach the air bag to the upper arm, one end of the wire is fixed to the outer side end part of the backing material, and the other end of the wire is connected to an automatic winding part. The wire is wound around for two or more times in the outer peripheral direction of the air bag and arranged.COPYRIGHT: (C)2011,JPO&INPIT【課題】上腕を挿入するだけでカフを密着させて容易にしかも正確に血圧測定を行うことができる電子血圧計を提供する。【解決手段】上腕を腕帯部2の挿入部に挿入し、該上腕に空気袋14を密着させて血圧を測定する電子血圧計であって、該腕帯部は、弾性を備えた渦巻形状の帯体をなすバッキング材15と、前記バッキング材の内側の全周に配置されている空気袋14とを有し、該空気袋を前記上腕に密着させるために、ワイヤー12が前記バッキング材の外周に巻き付けられており、前記ワイヤーの一端が前記バッキング材の外側端部に固定されており、かつ、前記ワイヤーの他端が自動巻き取り部に接続されて構成され、前記ワイヤーは、前記空気袋の外周方向に対して、複数周巻き付けて配置されている。【選択図】図3
