The conductor 5 has a pair configuration of 5a and 5b, 5c and 5d, 5e and 5f, 5g and 5h, and a set of four conductors 5a to 5d and 5e to 5h as shown in FIG. 5 are connected to one output terminal 8 via electric wiring 12 respectively.

  Although detailed description is omitted, the electrodes 6a to 6d and the electrodes 6e to 6h are connected to the current-carrying connection portion 9 of the output terminal 8 through unillustrated wires, respectively, and the suction cups 7a to 7d and the suction cups 7e to 7e are connected. 7h is connected to the suction connection portion 10 of the output terminal 8 via a suction pipe (not shown). The electric wire and the suction pipe are combined as one electric wiring 12.

  An open / close cover 14 is provided at a position above approximately half of the front surface of the housing main body 13 of the interference low-frequency treatment device 1 so that the left side portion is hinged to the housing main body 13 via a hinge. Two output connectors 15, 15 to which the output terminals 8 are connected are laterally provided in the vicinity of the upper and lower central portions of the front surface of the housing body 13 with the opening / closing cover 14 opened.

  When each output terminal 8 is inserted into each output connector 15, the electrodes 6 are energized and connected so that the output from the output oscillation circuit 2 is applied to each electrode 6. At the same time, the suction connection of the suction cup 7 is made. After fitting a conductive member such as a sponge moistened with water into the suction cup 7, the suction cup 7 is attached to the affected part M of the patient and the pump 11 is driven. The cup 7 is securely fixed to the affected part M.

  As shown in FIG. 4, an operation panel 16 is erected on the top of the housing body 13. As shown in FIG. 2, the operation panel 16 has two channels (ch. 1 and ch. 2) having the same configuration on the left and right sides, and the output and output time described later are adjusted and set in each channel. In addition to the adjustment setting means 20 to be performed, various indicators are arranged. Hereinafter, the left channel (ch. 1) in FIG.

  In FIG. 2, 17 is an output adjuster for manually rotating and adjusting the output from the conductor 5, and 18 is an output time setter configured of a time increase switch 18a and a time decrease switch 18b for setting an output time (treatment time). 19 is an output time indicator that displays the remaining time until the end of output, 21 is an output current indicator that displays an output value (current value) flowing between two pairs of conductors, and for example, 21a is a conductor. Between 5a and 5b, 21b displays the output value which flows between the conductors 5c and 5d. The output values flowing between the conductors connected to each channel are automatically balanced by the automatic autobalance function of the control circuit 25. A stop switch 22 stops the output.

  In FIG. 2, reference numeral 24 denotes an interference mode switching switch as the interference mode switching means 23, and the operator can arbitrarily switch between the 4-pole interference mode and the 8-pole interference mode by pressing the switch 24. The quadrupole interference mode refers to a treatment mode using a set of four conductors 5 as shown in FIG. 3 (a), and the octupole interference mode refers to eight two-pole interference mode shown in FIG. 3 (b). The treatment mode using the pair of conductors 5 shall be said. When the 4-pole interference mode is selected, the LED on the left side of the character indicated as 4-pole lights up in the vicinity of the upper left position of the interference mode changeover switch 24, and when the 8-pole interference mode is selected, it is indicated as 8-pole. The LED on the left side of the letter lights up.

  Further, the interference low-frequency treatment device 1 has an output (current) value higher than a predetermined value even when an operator or the like erroneously operates the output adjuster 17 in the direction of increasing the output. An output limit value that limits the increase so as not to increase can be set. The output limit value is set to a desired value by appropriately pressing the time increase switch 18a or the time decrease switch 18b of the output time setting unit 18 while pressing the stop switch 22. In one set of conductors 5, the output limit value between each pair of conductors 5 is displayed as the same value on the output current indicators 21a and 21b.

  Next, a method of using the interference low frequency treatment device 1 will be described. When treating one affected part M of one patient using the quadrupole interference mode, the opening / closing cover 14 on the front surface of the housing body 13 is opened, and the output terminal 8 of the set of four conductors 5 (5a to 5d). Ch. Connected to the output connector 15 on one side (left side in FIG. 4). Four conductors 5 are mounted around the affected area M so that the outputs flowing between the conductors 5a and 5b and between the conductors 5c and 5d intersect each other on the affected area M (for example, FIG. )reference).

  The interference mode switch 24 is pressed to select the 4-pole interference mode. This operation is not necessary when the 4-pole interference mode has already been selected. When the output time is set by the output time setting unit 18, the set time is displayed on the output time display 19.

  Next, the output time setter 18 is operated while pressing the stop switch 22 to set an output limit value (for example, 30 mA). The output limit value between the conductors 5a and 5b and between the conductors 5c and 5d is the same value (30 mA) displayed on the output current indicator 21a and the output current indicator 21b, respectively. This operation is not necessary if the output limit value has already been set. As a result, preparation before the start of treatment is completed, and the output adjuster 17 is slowly rotated clockwise from the zero position to increase the output and start treatment.

  Since the output values between the conductors 5a and 5b and between the conductors 5c and 5d are automatically balanced by the auto balance function, the operator does not need to pay attention to fine output adjustment. The output frequencies between the conductors 5a and 5b and between the conductors 5c and 5d are set in advance. Each output frequency is set to, for example, 5000 Hz and 4880 Hz.

  When treating two affected areas M of one patient or one affected area M of two different patients at the same time using the quadrupole interference mode, another set of conductors 5 (5e to 5h) Output terminal 8 is connected to ch. Connect to the output connector 15 on the second side (right side in FIG. 4). The interference mode switch 24 is pressed to select the 4-pole interference mode. When the quadrupole interference mode is selected, the control circuit 25 causes the ch. 2 is set to ch. 1 can be operated independently of the operator 1, 1 and ch. 2 and the output limit value can be adjusted and set as appropriate in addition to the output and the output time according to the treatment site and the patient's symptoms. As with the one set of conductors 5 described above, for example, the output frequencies of the other set of conductors 5 (between the conductors 5e and 5f and between the conductors 5g and 5h) are also set in advance to 5000 Hz and 4880 Hz, respectively. Is done.

  Next, a case where treatment using the octupole interference mode is performed will be described. The output terminal 8 of each pair of conductors 5 is connected to ch. 1 and ch. Connect to 2 respectively. Eight conductors 5 so that the outputs flowing between the conductors 5a and 5b, between the conductors 5c and 5d, between the conductors 5e and 5f, and between the conductors 5g and 5h on the affected area M are in the crossing positions and directions. Is mounted around the affected area M (see, for example, FIG. 3B). The output frequency between the conductors is preset to, for example, 5000 Hz between the conductors 5a and 5b, 4880 Hz between the conductors 5c and 5d, 4760 Hz between the conductors 5e and 5f, and 4640 Hz between the conductors 5g and 5h. .

  The interference mode switch 24 is pressed to switch to the 8-pole interference mode. When the control circuit 25 recognizes that the signal has been switched to the 8-pole interference mode, the ch. All operations related to output adjustment by 2 are prohibited. 2 cannot be used. Therefore, the operator mistakenly selects ch. In addition to the case where the output adjuster 17 is operated, the output is not inadvertently changed even when the operator unintentionally touches the output adjuster 17. Safety is guaranteed.

  Ch. By operating the output regulator 17 on the one side, ch. 1 and ch. 2 can simultaneously adjust the output of the conductor 5 connected to both of the two. By operating the output time setting unit 18 on the one side, ch. 1 and ch. 2 can simultaneously set the output time of the conductor 5 connected to both. Therefore, the operator can select ch. 1 and ch. It is not necessary to repeat the same operation for each of the two, and output adjustment and output time setting work can be performed more easily. Ch. By operating only one side, ch. 1 and ch. The output limit value between a total of four pairs of conductors 5 connected to both of the two pairs can be set simultaneously.

  At this time, ch. 2 is turned off and the output time is not displayed. It can be easily recognized at a glance that 2 is disabled.

  ch. When the output adjuster 17 is slowly rotated clockwise from the zero position to increase the output and start the treatment, the output value between the pair of two conductors 5 (total of 4 sets) is automatically set to the same value by the auto balance function. The output value is ch. 1 and ch. 2 is displayed on each output current indicator 21.

  After the treatment in the octupole interference mode is completed, when the octupole interference mode is switched from the octupole interference mode to the quadrupole interference mode by the interference mode switch 24, this signal is recognized by the control circuit 25 and cannot be used. 2 is automatically changed to be usable.

  Note that the present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the gist of the present invention. For example, in the above-described embodiment, the conductor has been described by taking the suction conductor as an example, but the object of the present invention can be achieved even if a known adhesive gel conductor or the like is used as the conductor. In addition, a configuration including two channels (ch. 1 and ch. 2) and one interference mode switching unit 23 in FIG. 2 is defined as one unit, and a plurality of units are provided on the operation panel 16, and each unit is provided. Of course, the treatment can be performed independently.

  The present invention can be expected to be used as an interference low-frequency treatment device that stimulates and treats an affected area by passing and interfering with two or more medium-frequency currents having different frequencies in the body. It is extremely expensive.
