It is in the form of a square wave, and the positive turn-on section Ton1 and the negative turn-on section Ton2 may be set to 2 msec, for example.

In addition, as shown in FIG. 7, the pattern of the intensity control signal output from the control unit 30 includes an intensity increase section t1 at which the stimulus intensity gradually increases, and a time point at which the intensity increase section t1 ends. The intensity duration section t2 that maintains the stimulus intensity at a constant intensity and the rest period t3 that cuts off the current at the end of the intensity duration t2 are repeated at predetermined intervals.

Here, the intensity increasing section t1 may be configured to last for 3 to 5 seconds, the intensity sustaining section t2 for 2 to 4 seconds, and the rest section t3 for 4 to 6 seconds, respectively. The intensity increase section t1 may be increased for 4 seconds, the intensity duration section t2 may be maintained for 3 seconds, and the rest period t3 may be repeated for 5 seconds.

Constant while the maximum output voltage was limited to about ± 45V.

In addition, the stimulation electrode 40, 42, as shown in the accompanying drawings, Figures 4 and 5, when the bowel movement 20 sits on the toilet 80, the stimulation electrode 40, 42 is easy to bowel movement When the left toilet seat 82 of the toilet seat 80 is opened and vertically opened so as to be in contact with the spinal cord spring 10 located at the buttocks 22 and 24 of the 20, the left and right buttocks of the bowel movement 20 are approximately vertical. (22) and (24) installed on the inner left and right sides of the toilet seat cover 82 to match the height, the stimulation electrodes 40, 42 is composed of, for example, sponge-type pad widely used in physical therapy electric stimulator In order to excite the pelvic nerve involved in defecation reflection, an irrelevant electrode was used as the right side of the electrodes 40 and 42 for stimulation on the left and right sides.

In addition, when the stimulus is unpleasant, if the upper body is slightly bowed forward, the spinal cord 10 falls away from the stimulation electrodes 40 and 42 and the stimulation electrodes 40 and 42 and the human body are separated from each other. It was not delivered.

In addition, the electrical stimulation device for the treatment of constipation with left toilet according to the present invention is a functional electrical stimulation device for restoring motor function of patients with quadriplegia due to central nerve injury, as well as urinary function of the lower paraplegia due to spinal cord injury It may also be used for applications such as an electrical stimulation device for recovering, an electrical stimulation device for treating urinary incontinence, and the like.

In the figure, reference numeral 86 indicates a seat plate, 84 indicates a water tank, 13 indicates an anus, 14 indicates a rectum, 15 indicates an S-shaped colon, and 16 indicates a descending colon. .

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

As shown in FIGS. 1 to 7, when power is supplied to the controller 30, the intensity control signal for periodically changing the intensity of the predetermined signal and the stimulus signal of the predetermined pattern from the output port of the controller 30. Are output respectively.

At this time, the time constant of the stimulus signal can be arbitrarily changed by using the variable resistor VR2 connected to the input port of the controller 30, which is made by an embedded analog / digital converter and a timer.

Thereafter, the weak stimulus signal output from the output port of the control unit 30 is amplified while passing through the waveform amplifier unit 50 and then output to the stimulation electrodes 40 and 42 through the insulation coupler 32. The coupler 32 allows the waveform amplifier 50 and the stimulation electrodes 40 and 42 to be insulated from each other and connected to the primary side and the secondary side, respectively, so as to exchange a circuit with the defecator 20 simultaneously. To protect.

That is, as shown in FIG. 6, the stimulus signal output from the control unit 30 has a positive turn-on section Ton1 of 2 msec, a first turn-off section Toff1 of 48 msec, and a negative turn-on section ( Ton2) is a form of an ideal square wave having 2msec and 2nd turn-off section Toff2 set to 48msec, and one of the two output ports provided in the controller 30 has a positive turn-on section Ton1 and The current corresponding to one turn-off section Toff1 is supplied to the transistor Q1 on one side, and the other output port corresponds to the negative turn-on section Ton2 and the second turn-off section Toff2. The stimulus signal is formed while supplying current to the transistor Q2 on the other side.

On the other hand, the intensity control signal of the PWM type output from another output port of the control unit 30 is smoothed by a DC component while passing through the resistor (R1) and the capacitor (C1) constituting the integrated circuit unit 60, and then variable After the voltage is divided by the resistor VR1, the voltage amplifier 70 is amplified to control the voltage applied to the secondary side of the insulating coupler 32.

That is, as shown in FIG. 7, the pattern of the intensity control signal output from the control unit 30 has an intensity increase section t1 at which the stimulus intensity gradually increases, and at the time when the intensity increase section t1 ends. An intensity duration section t2 that maintains the stimulus intensity at a constant intensity and a rest period t3 that cuts off the current at the end of the intensity duration section t2 are repeated at predetermined intervals, for example, an intensity increase section t1. Is gradually progressed for 4 seconds, the intensity duration section t2 continues continuously for 3 seconds, and the resting section t3 lasts for 5 seconds, respectively.

Thus, the stimulus intensity control signal proceeds to "ON" for 7 seconds, "OFF" for 5 seconds, and when the stimulus signal is "ON", the stimulus intensity gradually increases for 4 seconds, and the maximum value is reached. When it reaches, it is kept constant for 3 seconds, then remains "OFF" for 5 seconds and then repeats from the beginning.

In this case, when the user or the toilet 20 changes the variable resistor VR1, the output intensity can be arbitrarily adjusted.

In the state in which the stimulus signal whose intensity is periodically changed from the stimulation electrodes 40 and 42 is output as described above, the toilet 20 opens the toilet seat 82 of the toilet seat 80 and sits on the seat plate 86. When the spinal cord 10 is located at the left and right buttocks 22 and 24 of the bowel movement 20, the magnetic pole electrodes 40 and 42 are installed in the left side of the toilet seat cover 82.

At this time, the stimulation signal output from the stimulation electrodes 40 and 42 is applied to the spinal cord intestinal tract 10 of the bowel movement 20 so that the pelvic nerves 11 and 12 of the bowel movement 20 are stimulated. This will promote bowel movements.

That is, as shown in FIGS. 3 and 4, the stimulation signal is transmitted from the stimulation electrodes 40 and 42 to the pelvic nerves 11 and 12 through the spinal cord sacral region 10 of the bowel movement 20. When applied, both the pelvic motor and pelvic sensory nerves that make up the pelvic nerves (11) (12) are stimulated and transmitted to the S-shaped colon (15), rectum (14), and internal sphincter, respectively, under its control. Rectal (14) is contracted, and the internal anal sphincter is to relax the bowel movement is repeated.

As described above, the present invention excludes drug use for constipation treatment because it is configured to stimulate the pelvic nerve of the bowel movement by physical electrical stimulation to promote bowel movements and prevent constipation and at the same time help treatment. It is possible to eliminate the side effects caused by this, and because the stimulation electrode is installed on the toilet seat cover, the bowel movement is facilitated by sitting on the toilet seat, it is possible to prevent constipation to ejaculate, and the convenience of use There is.
