Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The power supply unit supplies a predetermined level of voltage, and is composed of one or more batteries or rechargeable batteries.

The input functions to adjust the factor of the output and includes a power switch 22, a hold switch 24, a mode select switch 26, an up switch 28 and a down switch 29 It is configured to include).

1 is a front view of a menstrual pain alleviator according to the present invention, in which an input unit and a display unit are shown.

The power switch 22 and the holding switch 24 are constituted by slide switches, and the selector switch 26, the increase switch 28, and the reduce switch 29 are constituted by push button switches. It is desirable to be.

The power switch 22 is a switch for applying and cutting off power, and when the power is on, the device can be used. In the off state, the power is cut off so that the device cannot be used.

The hold switch 24 does not operate the adjustment switch in order to prevent a user from feeling uncomfortable by adjusting the pulse output due to the operation of the switch when the user is active while wearing the device. It is a switch for. In addition, the holding switch 24 is to cut off power of the display unit and to reduce the power consumption by making the operation mode of the CPU into the saving mode. When the holding switch 24 is in the off state, the data is displayed on the display unit and the output factor may be adjusted by operating the pushbutton switch. When the holding switch is turned on, the display on the display disappears and the pushbutton is not operated. Therefore, even if the push button switch is pressed for any reason, the output factor is not adjusted and thus it is safe and can reduce power consumption.

The mode select switch 26 is a switch capable of selecting a pulse output mode of the output driver. When the push button is pressed, the pulses are selected in the order of intensity, speed, wave width, and waveform, and when the selector switch 26 is pressed again in the selected state, the cycle returns to the beginning. Once each output mode is selected, you can modify the output factor for that mode. The correction of the output factor is corrected by operating the increase switch 28 and the decrease switch 29.

The up switch 28 modifies in the direction of increasing the factor, and the down switch 29 modifies in the direction of decreasing the factor. Unlike the selection switch 26, the increase and decrease switches 28 and 29 do not cycle, and the factor is not changed even if the switch is operated in the direction of increasing and decreasing at the highest point and the lowest point. If the factor changes sharply from the highest point to the lowest point, it may cause unpleasantness during the operation, so the non-cyclic switch is operated.

The display unit 50 displays the type of mode, the selected output mode, and the current factor according to the input signal of the input unit on the LCD screen.

2 is a diagram illustrating an LCD screen of a display unit. The display unit displays the output mode of the pulse and the factor of the mode is displayed numerically in the corresponding part.

The output mode of the pulse is composed of four modes of pulse intensity, velocity, wave width, and waveform, and a factor value is defined for each mode.

4 is a diagram showing the intensity, speed and wave width of the pulse according to the present invention.

The intensity represents the intensity of the pulse, and is divided into eight levels and is displayed as 0 to 7 from the low voltage on the display. The peak voltage of the actual voltage is 10-30V. Each step is designed as 10, 15, 17.5, 20, 22.5, 25, 27.5 and 30V.

The speed represents the speed of the pulse and is expressed in PPS, the number of pulses per second. The speed is divided into five stages and displayed on the display as 0 to 4. Each stage is designed with 20, 25, 50, 100 and 200.

Wavewidth represents the width of a waveform, i.e., the time for outputting a pulse and maintaining its voltage. The wave width is divided into five stages and is displayed as 0 to 4 on the display unit. Each stage is designed in 50, 100, 150, 200 and 250 Hz.

5 is a view showing a waveform of a pulse according to the present invention.

The waveform shows the shape of the pulse, which is divided into three types and is displayed as 0 to 2 on the display. The first and second waveforms are unidirectional pulses, the first pulse being a constant voltage pulse as zero, and the second pulse as a negative voltage pulse as one. The third waveform is a two-way pulse, represented by two. The waveform has the same intensity, velocity, and width of the pulse, and outputs only the polarity of the pulse output. The waveform may be selected for a short time, but it is preferable to use a third type for long time.

The display unit 50 can view the mode and the factor at a time, and the current mode can be known by causing the letters indicating the mode to blink for the currently selected mode. Operating the increment and decrement switches 28 and 29 with the mode selected will display the corresponding factor numerically. If the mode is to be changed, the mode is switched by pressing the selection switch 26.

The CPU 30 determines a signal input from the input unit and outputs a control signal. It is preferable to apply a programmable microprocessor. In addition, the CPU 30 preferably outputs data to the display unit to display the data.

The pulse generator comprises a DC-DC converter 42 for amplifying a control signal output from the CPU, an analog switch for adjusting the voltage of the converter, and a pulse driver 46 for generating a pulse to generate a pulse.

The pad is a means for delivering the pulse to the human body. An electrode may be attached to the pad to transmit the pulse output to the human body. As the electrode, a tab electrode, an electrode to which an electric wire is connected, or the like can be used. The tab electrode has a side tab electrode connected from the side and a top tab electrode connecting the electrode to the upper side in a manner of connecting with the wire. Electrodes or cable electrodes connected to the wire has the advantage that the display does not appear well when worn on clothes.

The electrode can be attached very simply using a form in which an adhesive (gel) is pre-painted, and it is preferable to use it while moving several times.

The dysmenorrhea relievers of the present invention configured as described above can see the state of the selected mode and factor through the liquid crystal display, and when a signal is input by operating a button at the input unit, a pulse is generated to relieve the menstrual pain of the woman wearing the menstrual pain relievers. .

3 is a configuration diagram of the menstrual pain alleviator according to the present invention, the operation of the menstrual pain alleviator according to the present invention with reference to FIG.

When the user turns the power switch on, the dysmenorrhea is powered and the LCD screen displays the mode and output factor.

The user can operate the selection switch, the increase switch and the decrease switch of the input unit to adjust the output mode and output factor, and at the same time the output mode and output factor are displayed on the LCD screen.

The signal input by the user is input to the CPU, and the CPU determines the input signal and outputs a control signal.

The control signal output from the CPU is amplified by the DC-DC converter 42 to generate a pulse in the pulse driver 46.

The user may alleviate the pain by transmitting the pulse output of the menstrual pain alleviator to the human body. Therefore, the menstrual pain alleviator includes a pad for delivering a pulse output to the human body. In addition, even when the selection switch, the increase switch and the decrease switch are pressed after being worn on the human body, the holding switch may be operated safely to prevent the output factor from being adjusted.

The menstrual pain alleviator is worn so that the electrode of the pad contacts the abdomen and back of the human body.
