1)測定されるべき生体信号の大きさ(電位差)の下限基準値を予め設定しておき、実測した生体信号の大きさ(電位差)が下限基準値を超えているかどうかを基準にして、制御部16が判断する。
2)生体信号が測定されるまでの時間帯(潜時)を予め設定しておき、実測された生体信号が設定した時間帯(潜時)に測定できたかどうかを基準にして、制御部16が判断する。生体信号が測定されるまでの時間帯は、刺激印加電極による仙骨3背面への刺激印加時刻(0ミリ秒)から、約10ミリ秒~30ミリ秒経過時までに設定することが望ましい。
図4は、本発明の実施の形態2における排尿障害治療器を示す。実施の形態2の排尿障害治療器の刺激伝達検出電極は、大腿二頭筋6と9(図3参照)よりも内側に存在する半腱様筋30と31の背面に配置されている。すなわち、刺激伝達検出電極7aと7bを、左脚5の半腱様筋30の背面に配置し;かつ刺激伝達検出電極10aと10bを、右脚8の半腱様筋31の背面に配置している。
図5は、本発明の実施の形態3における排尿障害治療器を示す。実施の形態3の排尿障害治療器の刺激伝達検出電極は、大腿二頭筋6と9(図3参照)や、半腱様筋30と31(図4参照)よりも下肢遠位部に存在する、腓腹筋24と25の背面に配置されている。すなわち、刺激伝達検出電極7aと7bを左脚5の腓腹筋24の背面に配置し;刺激伝達検出電極10aと10bを右脚8の腓腹筋25の背面に配置している。
図6は、本発明の実施の形態4における排尿障害治療器を示す。実施の形態4の排尿障害治療器の刺激伝達検出電極は、腓腹筋24と25(図5参照)よりも遠位の後外側にあるヒラメ筋33と34の背面に配置されている。すなわち、刺激伝達検出電極7aと7bを、左脚5のヒラメ筋33の背面に配置し;刺激伝達検出電極10aと10bを、右脚8のヒラメ筋34の背面に配置している。
そして、本発明の排尿障害治療器は刺激伝達検出電極を有し、前記刺激信号に応答して発生する生体信号を検出することができる。その生体信号を測定することで、適切な生体信号が与えられているかを表示手段に表示することができる。治療者は、前記表示を確認しながら、適切な刺激信号を与えられるように一対の刺激印加電極の配置位置を適切に調整することができる。それにより適切な治療を実現する。
