## Abstract

An electrical stimulation treatment device includes a pair of application electrodes which are disposed at a site of the skin of a person to be treated where an electrical stimulation is to be given and which supply the electrical stimulation to the skin and a control unit which is connected electrically to the application electrodes to control a magnitude of a stimulation voltage which is supplied to the application electrodes, in which the control unit includes a calculation means for calculating a magnitude of the stimulation voltage which is to be output, depending on a first maximum stimulation voltage set for each person to be treated and an elapsed time or a stimulation frequency from the start of a stimulation session of a predetermined time, and an output means for outputting the stimulation voltage while increasing the voltage in a stepwise manner based on the calculation results of the calculation means.

## Claims

### Claim 1

An electrical stimulation treatment device comprising:
a pair of application electrodes which are disposed at a site of the skin of a person to be treated where an electrical stimulation is to be given and which supply the electrical stimulation to the skin; and
a control unit which is electrically connected to the application electrodes to control a magnitude of a stimulation voltage supplied to the application electrodes; wherein
the control unit includes
a calculation means for calculating a magnitude of the stimulation voltage which is to be output depending on a first maximum stimulation voltage set for each person to be treated and, an elapsed time or a stimulation frequency from the start of a stimulation session of a predetermined time, and
an output means for outputting the stimulation voltage while increasing the voltage in a stepwise manner based on the calculation results of the calculation means.

### Claim 2 (depends on 1)

The electrical stimulation treatment device according to claim 1, wherein
the calculation means includes a storage portion which stores storage information based on how long a time has elapsed or how many times stimulation has been given from the start of the stimulation session in order to attain the first maximum stimulation voltage, and calculates an increase rate of the stimulation voltage based on the storage information of the storage portion when the elapsed time or the stimulation frequency from the start of the stimulation session is input, thereby calculating a magnitude of the stimulation voltage based on the increase rate.

### Claim 3 (depends on 1)

The electrical stimulation treatment device according to claim 1 which includes an input portion operated by a person to be treated when the person to be treated feels that stimulation is strong, wherein
when the input portion is operated before attainment of the first maximum stimulation voltage, the output means does not increase the stimulation voltage until termination of the stimulation session from a time when the input portion is operated.

### Claim 4 (depends on 3)

The electrical stimulation treatment device according to claim 3 which includes a switch means capable of switching the voltage to the first maximum stimulation voltage or a calculation stimulation voltage calculated by the calculation means as a second maximum stimulation voltage which is used actually until termination of the stimulation session, wherein
the output means uses the calculation stimulation voltage as the second maximum stimulation voltage when the input portion is operated before attainment of the first maximum stimulation voltage.

### Claim 5 (depends on 4)

The electrical stimulation treatment device according to claim 4 which includes
a comparison means for comparing information based on how long a time has elapsed or how many times stimulation has been given from the start of the stimulation session in order to attain the first maximum stimulation voltage, with information on an actual elapsed time or an actual stimulation frequency from the start of the stimulation session, and
a selection means for selecting a type of voltage of the switch means based on the comparison results of the comparison means when the input portion is operated.

### Claim 6 (depends on 1)

The electrical stimulation treatment device according to claim 1, wherein
the electrical stimulation treatment device includes a urination disorder treatment device.
