PROBLEM TO BE SOLVED: To provide an electrostimulator which reduces labor and costs required for maintenance, by preventing a failure in a suction pump, and which prevents a user from performing wrong handling.SOLUTION: An electrostimulator 1 brings internal spaces of suction electrodes 2a and 2b into negative pressure by a suction pump 3, and performs energization treatment by attaching the suction electrodes 2a and 2b to the human body 15. An air-water separation tank 4 is provided between the suction electrodes 2a and 2b and the suction pump 3. The air-water separation tank 4 makes moisture separated from air sucked in from the suction electrodes 2a and 2b.COPYRIGHT: (C)2014,JPO&INPIT【課題】吸引ポンプの故障を防止して、メンテナンスに要する手間とコストとを低減し、また、ユーザが誤った取り扱いをしないで済む電気刺激装置を提供する。【解決手段】吸引導子2a,2bの内部空間を吸引ポンプ3により負圧にして該吸引導子2a,2bを人体15に装着して通電治療をする電気刺激装置1であって、吸引導子2a,2bと吸引ポンプ3との間に気水分離槽4を設け、この気水分離槽4により、吸引導子2a,2bから吸引されたエアから水分を分離するようにした構成。【選択図】図1
