PROBLEM TO BE SOLVED: To provide an electronic sphygmomanometer having a lightweight and compact arm band.SOLUTION: The electronic sphygmomanometer 1 includes the cylindrical arm band 2 for inserting an upper arm and a sphygmomanometer body 10, which are formed as separate bodies. The arm band 2 includes an airbag 14 which forms at least part of the inner surface of the cylindrical body a deformable and stretch abutting fabric 17 formed as a cylindrical body covering the inner surface of the airbag 14 to abut to a measured surface of the upper arm and an outer member 16 joined to the outside of the abutting fabric to house the airbag and formed of a deformable but non-stretch fabric member.COPYRIGHT: (C)2011,JPO&INPIT【課題】軽量でコンパクトな腕帯部を有する電子血圧計を提供する。【解決手段】電子血圧計1は、上腕を挿入する筒体の腕帯部2と、血圧計本体10とを有し、腕帯部2と血圧計本体10とが別体に形成されており、腕帯部2は、少なくとも筒体の内面の一部を形成する空気袋14と、空気袋14の内面を覆う筒体でなり変形可能で伸縮性を有し、上腕の被測定面に当接する当接布部17と、空気袋を収容するように当接布部の外側に接合され、変形可能であるが伸縮性の無い布部材で形成された外側部材16とを有する。【選択図】図1
