Classification: CPC A | IPC A

Claim 0:
1. An electrical stimulation treatment device comprising:
a pair of application electrodes configured to apply electrical stimulation to a skin of a person;
a controller configured to be electrically connected to the application electrodes to control a magnitude of a stimulation voltage supplied to the application electrodes; and
an input portion operated by the person when the person feels that the electrical stimulation is strong,
wherein the controller includes:
a first memory storing a preset first maximum stimulation voltage;
a second memory to store a second maximum stimulation voltage, wherein the second maximum stimulation voltage is less than first maximum stimulation voltage;
a calculation circuit;
an output circuit;
a storage portion, and
a comparison device,

wherein the controller is configured to:
deliver, with the output circuit, a stimulation voltage based on a preset frequency and a preset duration,
calculate, with the calculation circuit, a stepwise increase based on a magnitude of the stimulation voltage and at least one of the preset frequency or the preset duration,
apply, with the output circuit, the stepwise increase to the stimulation voltage,
determine a first or a second condition, with the comparison device, wherein the first condition is met when the stimulation voltage reaches the first maximum stimulation voltage and the second condition is met when the stimulation voltage is less than the first maximum stimulation voltage,
when the first condition is determined, continue applying, with the output circuit, the stimulation voltage,
when the second condition is determined and the input portion has not been operated, repeat the calculate, apply and determine steps,
when the second condition is determined and the input portion has been operated, compare, with the comparison device, an actual frequency or an actual duration time corresponding to a treatment time period from a start of stimulation to the operation of the input portion,
when the actual frequency or duration exceeds the preset frequency or duration, respectively, deliver, with the output circuit, the stimulation voltage set at the first maximum voltage continuously until termination of a treatment session,
when the actual frequency or duration is lower than the preset frequency or duration, respectively,
deliver, with the output circuit, the stimulation voltage set at the second maximum voltage continuously until termination of a treatment session.
