Patent ID: 7471984

Claim:
A low-frequency treatment device comprising: electrodes to which a low-frequency pulse signal is supplied so that an electric stimulus is applied to a living body via the electrodes; a muscle contraction frequency setting section for presetting a number of times of muscle contraction which occurs by applying the electric stimulus to the living body; a pulse mode setting section for setting a conducting time period and a pausing time period in an interval, wherein the pulse signal is conducted in the conducting time period and is not conducted in the pausing time period; a treatment time computing section for computing a treatment time period based on the number of times of muscle contraction set by the muscle contraction frequency setting section and on the conducting time period and the pausing time period set by the pulse mode setting section; a timer which starts counting a time period when supply of the pulse signal is started, and transmits a stop signal for stopping the supply of the pulse signal when the counted time period reaches the treatment time period computed by the treatment time computing section; and a shut-off device for shutting off a circuit for supplying the pulse signal based on the stop signal received from the timer.
