The low-frequency therapeutic device 10 according to the present invention is shown in FIGS.
As shown in the figure, the output control switch described later is provided at the center of the upper surface 14 side of the rectangular flat main body case 12.
While 16 operation knobs 18 and 19 are arranged side by side, the knob 21 of the registration switch 20 is located below the knobs 18 and 19,
A knob 23 of the automatic operation switch 22 is provided at an upper position. Furthermore, the registration switch 20 and the output control switch 16
A light emitting diode 24 that indicates a difference in operation mode is provided between them.

On the other hand, the therapeutic signal 26 is
The electronic circuit 30 includes a battery 32 that supplies driving power to the electronic circuit 30. In addition, a variable resistor 36 for output adjustment having a power switch 34 that regulates the timing of current supply from the battery 32 to the electronic circuit 30 is provided at a side position of the main body case 12, while A jack 38 for detachably connecting the child 28 is provided.

The lead 28 is a therapeutic signal output from the body case 12 side.
26 for applying 26 to the skin surface of the affected part, comprising a flat electrode 42 on an insulating base 40 and covering the electrode 42 with a conductive adhesive pad 44. A pair of electrodes 42 is connected to the jack 38 on the body case 12 side by a plug 48 at the end of the cord 46.

The electronic circuit 30 includes, as a control unit 52, a one-chip microcomputer that operates in accordance with a program stored in a ROM, using a clock signal output from an oscillation unit 50 shown in FIG. 3 as a reference signal. In the control unit 52, a selection signal input from the output selection unit 54 as shown in FIG.
The drive signal 58 corresponding to the selected state is sent to the output unit 60 in conjunction with the input of 56a and 56b.

On the other hand, in the display unit 62, the display corresponding to the difference in the drive mode by the output selection unit 54, for example, the color or blinking of the light emitting diode 24 on the upper surface 14 of the main body case 12 in response to the difference such as whether the drive mode is manual or automatic. The display that changes the state is performed.

The output selection unit 54 has two output control switches 16 for manually outputting the therapeutic signal 26 simulating the “hit” and “fum” states at the time of acupressure, and is preset in the device. A registration switch 20 for temporarily storing an output waveform manually selected using an automatic switch 16 for outputting a signal according to a procedure and automatically executing the output waveform.

The output unit 60 has a configuration substantially the same as that of the related art, and converts a low voltage of about several V output from the battery 32 to a high voltage of several tens V or more using a chopper type booster circuit 64, for example.
That is, in conjunction with the input of the boost signal 66 of a sufficiently high frequency output from the control unit 52, the current flowing through the choke coil is continuously generated at a high speed to generate a pulse voltage, and this voltage is integrated by a capacitor, thereby obtaining a battery. It forms a voltage sufficiently higher than the voltage.

On the other hand, a drive signal 58 is sent from the control unit 52 to the output control circuit 68 in response to the selection signal 56 input from the output selection unit 54. The output control circuit 68 controls the ON timing of the output circuit 70 for regulating the output of the high voltage formed by the booster circuit 64, and interlocks with the input of the drive signal 58 to generate a control signal of a predetermined shape. 72 is sent to the output circuit 70, and the charge stored in the capacitor in the booster circuit 64 is extracted as a pulse-like output signal 74.

The output signal 74 extracted by the output circuit 70 is divided by the variable resistor 36 to a required peak value,
・ Because it is sent as a therapeutic signal 26 toward 42, the conductor 28
The predetermined low-frequency current flows on the skin surface between the electrodes 42 by separating the adhesive pad 44 from the affected area in advance.

The present invention is characterized in that, in the above-described configuration, the pattern of the therapeutic signal 26 manually selected by operating the output control switch 16 provided in the output selection unit 54 is stored and automatically executed.

That is, when the operating knob 18 on the `` slap '' side provided on the surface of the main body case 12 is pressed, regardless of the pressing length of the knob 18,
The therapeutic signal 26a is output as a single-shot pulse signal, with pulses of one or both polarities forming a pair. On the other hand, when the operation knob 19 on the `` mum '' side is pressed, only during the period when the knob 19 is pressed, for example, at a frequency of about several kHz, a pulse train whose peak value is constant or gradually increases as the therapeutic signal 26b Is output. Therefore, both operation knobs 18.1
When the user presses 9 at an arbitrary timing, a series of therapeutic signals 26 corresponding to the operation state is output to the guide 28.

On the other hand, the control unit 52 constantly detects the pressing order and pressing interval of the operation knobs 18 and 19, and data corresponding to the detected content is sequentially stored in the RAM as data for a predetermined number of meticulous operations.

Here, the operation knob when the 18-19 therapeutic signal 26 that is output manually by pressing of it was confirmed that those satisfying goes for the operator, the registration switch 20 immediately above the time t ₁ If you enter a registration signal 51 by pushing the control unit 52, for example, four times of the switch operation performed in the period T from t ₀ to t ₁ is fixed as the stored data in the RAM. At the same time, the operation mode changes from the manual mode to the registration execution mode, and the state of the mode conversion is displayed on the display unit 62.
, And the data fixed in the RAM is sequentially decoded from the oldest one and used as a signal for output control in the control unit 52. At this time, when the stored data in the time t ₂ is decrypted use to the most recent ones, by automatically repeatedly use the stored data as return to the oldest data again, manual content set in is continuously running It is done. The registration execution mode is automatically changed to another mode automatically after a predetermined time elapses by a timer provided separately or by operating an arbitrary knob again.

Note that, as in the above-described embodiment, the registration switch 20 is operated only at the time of registering the operation content, and the storage range is set by the configuration of the storage unit itself whose capacity has been regulated in advance. It is also possible to freely set the storage range by setting both the start and the cycle of the above with the registration switch 20.

Also, instead of repeating the data stored in the RAM unconditionally, only the pattern was extracted by approximating the repetition of the operation, and when this extraction was successful, a message to that effect was displayed and extracted. The pattern may be repeatedly executed.

Further, it is also possible to detect the pressing force of the operation knobs 18 and 19 and generate the treatment-like signal 26 having a peak value corresponding to the detected pressure, using the pressure as stored data.
