PROBLEM TO BE SOLVED: To provide an electronic sphygmomanometer which does not require the work of arranging filters and changing the filters and permits the number of parts to be reduced and has a lightweight and compact cuff portion which can be simply folded when it is not put to use.SOLUTION: The electronic sphygmomanometer 1 includes the cuff portion 2 as a cylindrical body which can pass through the upper arm and can be folded and a sphygmomanometer body 10. The cuff portion 2 and the sphygmomanometer body 10 are formed separately. The cuff portion 2 has a blood blocking airbag 14 pressurizing the upper arm T by supplying air, a butting cloth portion 17 made of a cylindrical body covering the inside of the blood blocking airbag 14 and butting against the side of the upper arm T which is to be measured and an outside member 16 joined to the outside of the butting cloth portion 17 so as to store the blood blocking airbag 14. A cushion material to reduce the amount of air to be supplied by reducing the volume of air in the bloodstream blocking airbag 14 is arranged on the outside of the blood blocking airbag 14.COPYRIGHT: (C)2012,JPO&INPIT【課題】フィルタの配置やフィルタの交換作業が不要で部品点数を減らすことができ、使用しない時には、簡単に折りたたむことができる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、上腕に通すことができ折り畳み可能な筒体の腕帯部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、空気を供給することで上腕Tを加圧可能な阻血用空気袋14と、阻血用空気袋14の内面を覆う筒体でなり、上腕Tの被測定面に当接する当接布部17と、阻血用空気袋14を収容するように当接布部17の外側に接合される外側部材16を備え、阻血用空気袋14の外側面には、阻血用空気袋14内の空気容量を減少させて供給するべき空気の量を減らすためのクッション材が配置されている。【選択図】図1
