MUSCLE RELAXATION MONITORING APPARATUS AND CALIBRATION PROCESSING METHOD

WIPO Patent Application WO/2021/085333

A1

A stimulation current value that causes the supramaximal stimulation according to the subject is detected in a short time period while reducing the burden imposed on the subject. An initial stimulation current value that is set to be smaller than a maximum value of a stimulation current based on information relating to the subject is started. An amplitude peak value that is based on a first stimulation current value that is a stimulation current value obtained before the stimulation current value is varied by a value corresponding to a step current value in a determined current value variable process is detected as a first peak value. An amplitude peak value of an electric signal that is based on a second stimulation current value that is varied by the value corresponding to the step current value from the first stimulation current value based on the determined current value variable process is detected as a second peak value. A stimulation current value of the maximal stimulation of the subject is detected based on a result of a comparison of the detected two peak values. A stimulation current value that is obtained by adding the step current value to the stimulation current value of the maximal stimulation is acquired as the stimulation current value of the supramaximal stimulation of the subject.
