PROBLEM TO BE SOLVED: To restore synchronous contraction of a cardiac tissue by outputting an appropriate defibrillation pulse when the heart is in a defibrillation state, and defibrillating the heart appropriately.SOLUTION: A defibrillator 1 includes: a pair of electrodes 2a and 2b arranged at the heart a constant current circuit 8 for supplying a constant current between the pair of the electrodes 2a and 2b a supply changeover part SW5 that changes over the supply of the constant current from the constant current circuit 8 to a pulse-like constant current an electric potential difference detection part 9 for detecting an electric potential difference between the pair of the electrodes 2a and 2b and a control part 7 for adjusting the value of the constant current supplied from the constant current circuit 8 based on the electric potential difference detected by the electric potential difference detection part 9 when the pulse-like constant current is supplied between the pair of the electrodes 2a and 2b by the supply changeover part SW5.COPYRIGHT: (C)2015,JPO&INPIT【課題】心臓が除細動状態にあるときに適正な除細動パルスを出力して心臓を適正に除細動して心臓組織の同期的な収縮を回復させる。【解決手段】心臓に配置される一対の電極2a,2bと、一対の該電極2a,2b間に定電流を供給する定電流回路8と、該定電流回路8からの定電流の供給をパルス状に切り替える供給切替部SW5と、一対の電極2a,2b間の電位差を検出する電位差検出部9と、供給切替部SW5により一対の電極2a,2b間にパルス状の定電流が供給されているときに電位差検出部9により検出された電位差に基づいて、定電流回路8から供給される定電流の値を調節する制御部7とを備える除細動装置1を提供する。【選択図】図1
