The right cervical electrode 21b can be composed of a positive electrode or a negative electrode. The right upper knee electrode 22b has a polarity different from that of the right groin electrode 21b, and is constituted by a negative electrode or a positive electrode.

  The right cervical electrode storage portion 21c is formed between the band 21a and the first strip-shaped conductive portion 21d by sewing the outer edge portion of the first strip-shaped conductive portion 21d formed in a mesh shape to the band 21a. A space for accommodating the right cervical electrode 21b is formed. The right upper knee electrode accommodating portion 22c is sewn between the band 22a and the second belt-like conductive portion 22d by sewing the outer edge portion of the second belt-like conductive portion 22d formed in a mesh shape to the band 22a.

That is, reference numerals 21a, 21b, 21c, 21d, 211, and 212 of the right neck electrode mounting member 21 correspond to reference numerals 31a, 31b, 31c, 31d, 311 and 312 of the left neck electrode mounting member 31, respectively. doing. Since the left upper knee electrode mounting member 32 is the same as the right upper knee electrode mounting member 22, detailed description thereof is omitted. That is, the reference numerals 22a, 22b, 22c, 22d, 221, and 222 of the right upper knee electrode mounting member 22 correspond to the reference numerals 32a, 32b, 32c, 32d, 321, and 322 of the left upper knee electrode mounting member 32, respectively. Yes. Here, the channels may be made independent for the right leg and the left leg, respectively. That is, the stimulation intensity may be adjusted independently for the right leg and the left leg.

  Next, the configuration of the electric signal output device 20 will be described. FIG. 4 is a block diagram showing a circuit configuration of the electrical signal output device 20.

  The electrical signal output device 20 includes a control circuit 210, a power supply circuit 202, a low frequency output driver 203, an oscillator 206, an operation mode selection switch 207, a reset circuit 208, an output adjustment main volume 209, And an amplifier circuit 200.

  The control circuit 210 is composed of a CPU or the like, and controls the entire electric signal output device 20. The power supply circuit 202 supplies operating power to the electrical signal output device 20. The low frequency output driver 203 outputs a low frequency pulse signal based on the control signal of the control circuit 210. The oscillator 206 supplies a clock signal having a predetermined frequency to the control circuit 210. The operation mode selection switch 207 is operated to select a stimulation pattern (described later) based on an electrical signal output from the electrical signal output device 20. The reset circuit 208 supplies a reset signal to the control circuit 210.

  The signal output from the low-frequency output driver 203 is steplessly adjusted in the output adjustment main volume 209 and output to the amplifier circuit 200. The amplification circuit 200 amplifies the signal output from the low frequency output driver 203 and outputs the amplified signal to the electrical stimulation wearing device 1. When the right leg and the left leg have independent channels, the right leg and left leg amplifying circuits 200 are provided, and the intensity of the signal output from each amplifying circuit 200 is individually adjusted. It is desirable to provide an output adjustment subvolume for the purpose.

  The control circuit 210 is driven based on a DC6V power supply by the power supply circuit 202 and a clock signal of 20 MHz, for example, excited by the oscillator 206, and outputs a control signal to the low frequency output driver 203. The low-frequency output driver 203 outputs a low-frequency pulse signal based on the DC6V voltage supplied from the power supply circuit 202 and the control signal from the control circuit 210.

  The operation mode selection switch 207 is operated to switch between a first output mode and a second output mode described below in accordance with an instruction input by an operation of an operation unit (not shown) by a user. That is, the operation mode selection switch 207 outputs an instruction signal for instructing one of the first output mode and the second output mode to the control circuit 210 according to the user's selection. The control circuit 210 outputs a control signal for generating an output pattern of either the first output mode or the second output mode to the low frequency output driver 203 in accordance with the instruction signal from the operation mode selection switch 207. The low frequency output driver 203 is based on the frequency and output timing corresponding to the first output mode or the second output mode indicated by the control signal from the control circuit 210 based on the voltage of DC6V supplied from the power supply circuit 202. An electrical signal is generated.

  Next, an electrical signal output pattern by the electrical signal output device 20 will be described. FIG. 5A is a diagram showing an output pattern in the second output mode by the electrical signal output device 20, and FIG. 5B is a diagram showing an output pattern in the first output mode.

  In the output pattern of the first output mode, as shown in FIG. 5B, a pulse signal having a frequency of 4 (Hz) is continuously output (that is, there is no time for prohibiting output). As shown in FIG. 5C, the output pattern in the second output mode repeats a stimulation pattern in which output is stopped for 2 seconds after a pulse signal having a frequency of 20 (Hz) is continuously output for 5 seconds.

Next, how to use the electrical stimulation wearing tool 1 and the electrical signal output device 20 will be described.
(1) In step 1, as shown in FIGS. 2A and 2B, the user wraps the right neck electrode mounting member 21 around the right neck of the human body and attaches the hook-and-loop fastener 211 to the hook-and-loop fastener. The right cervical electrode mounting member 21 is mounted by being pressed against 212. Similarly, the right above-knee electrode mounting member 22 is mounted by winding the right above-knee electrode mounting member 22 around the knee of the right leg of the human body and pressing the surface fastener 221 against the surface fastener 222. The left cervical electrode mounting member 31 is also mounted on the cervical region of the left leg of the human body in the same manner as the right cervical electrode mounting member 21. The left upper knee electrode mounting member 32 is also mounted on the knee of the left leg of the human body in the same manner as the right upper knee electrode mounting member 31.

  (2) In step 2, the user connects the conductive wire 201A extending from the electrical signal output device 20 to the contact 110A of the right neck electrode mounting member 21, and connects the conductive wire 201B extending from the electrical signal output device 20. The contact is made to the contact 110B of the right above-knee electrode mounting member 22. The left cervical electrode mounting member 31 and the left above-knee electrode mounting member 32 are also connected to the electrical signal output device 20 via the conductive wires 301A and 301B.

  (3) In step 3, the user operates the operation unit of the electric signal output device 20 to drop the power to the electric signal output device 20, and either one of the first output mode and the second output mode. The output mode is selected and the electric signal output device 20 is operated. The electrical signal output from the electrical signal output device 20 passes through the right cervical electrode mounting member 21 and the right above-knee electrode mounting member 22 as an electrical stimulation signal as the right leg of the human body (the right leg cervical region). To the knee). In addition, the electrical signal output from the electrical signal output device 20 passes through the left cervical electrode mounting member 31 and the left above-knee electrode mounting member 32 as an electrical stimulation signal as the left leg of the human body (the left cervical region). To the knee).

  As a result, efficient electrical stimulation along the muscle fibers can be applied to the muscles between the left and right leg necks and the knee. As a result, effective muscle movement can be induced.

  Furthermore, in the past, in order to induce effective muscle movement, electrodes had to be arranged in more positions, but in this embodiment, it is only necessary to arrange electrodes on the neck and knees. Therefore, the electrode mounting operation is simplified. Moreover, since the number of output adjustment volumes is reduced by reducing the number of electrodes, the operation burden can be reduced. That is, the burden on the unhealthy person who performs rehabilitation can be reduced.

(Second Embodiment)
Further, as shown in FIG. 6, a right elbow electrode 41 (corresponding to the third electrode) and a left elbow electrode 42 (corresponding to the fourth electrode) are attached to the two arms of the right arm and the left arm, respectively. May be. The second arm is a portion between the shoulder and the elbow, and can be rephrased as an upper arm. One of the right elbow electrode 41 and the left elbow electrode 42 can be a positive electrode and the other can be a negative electrode. Since the configuration of the mounting member for mounting these electrodes 41 and 42 on the human body is the same as that of the right neck electrode mounting member 21 and the like, detailed description thereof is omitted. The channels of the right elbow electrode 41 and the left elbow electrode 42 can be made independent of the channels of the electrodes attached to the legs. Therefore, efficient electrical stimulation along the muscle fibers can be applied to the muscles of the second arm with electrical stimulation intensities different from those of the legs.
