(B) Conventional technology Generally, a low-frequency treatment device is provided with a plurality (for example, a pair) of conductor electrodes, and these conductor electrodes are applied to an affected part to apply a low-frequency signal. As this kind of low-frequency treatment device, there has been proposed a device for fixing a waveform signal at the time of operation by key operation and continuously outputting the same (Japanese Patent Application No. 1-88404).
issue). When the low-frequency electric therapy apparatus schematically illustrating, when the continuity / resume switch SW ₁ shown in FIG. 5 1 Do押operated repeatedly outputs the same waveform signal at the operation time. When thereafter again switches SW ₁ to press operation, the waveform of the next waveform number is output. When outputting your favorite waveform signal,
Operating the switch SW ₁ again, turn off the electrode switch SW ₂ that waveform signal is stored. Then, power switch SW
_{When 2} is inserted, the stored waveform signal is output.

In conventional low-frequency electric therapy apparatus which issues the above (c) to be Solved by the Invention Since the storage-call by the combination of continuous / resume switch SW ₁ and a power switch SW ₂ is performed, his preferred when this treatment an attempt to store the waveform signals, turn off the power switch SW ₂ put switch SW _1, further next time of treatment in turn switch SW _2, is continued output is called its waveform signal. However, when you release the continuation put the switch SW ₁ and want to use also another waveform during this continuation output, and not again the above-mentioned stored procedures, can not be called the first of their favorite waveform to the next treatment at the time , There is an operational problem. In addition, there is, of course, a problem that a plurality of waveform signals cannot be stored and recalled.

The present invention has been made in view of the above problems, and has as its object to provide a low-frequency treatment device capable of storing a plurality of waveform signals desired by a user.

(D) Means and action for solving the problem In the low-frequency treatment device of the present invention, a plurality of conductor electrodes and at least two or more different waveform signals are automatically output in a time-sequential manner. Means for applying a waveform signal to the therapeutic electrode, and a manual operation for fixing the waveform signal output from the waveform signal output means to a waveform signal at the time of operation and continuously output when operated. Means, when operated, a plurality of manual operation means for designating a plurality of storages for designating storage of the waveform signal being output from the waveform signal output means, and one of these manual operation means for the storage designation In response to the operation, the storage means for storing the waveform signal being output at the time of the operation and the presence or absence of the continuous output, respectively, and when operated, the waveform signal and the continuous output stored in the storage means are distinguished from each other. Designation It is characterized by a plurality of manual operation means for designating a plurality of calls for successively outputting the called waveform signals or continuously outputting the called waveform signals from the calling and waveform signal output means.

When using the low-frequency treatment device, when the user sets the lead electrode at the treatment site and turns on the power switch, for example, waveform signals having different frequencies are sequentially output. When the user operates the manual operation means for fixing the waveform signal at the time of the preferred waveform signal from the applied stimulus, the waveform signal is fixed and continuously output. When the manual operation means for designating storage is operated during waveform output, the waveform signal at that time and the presence or absence of continuous output are stored in the corresponding storage area of the storage means. When another manual operation means for designating storage is operated, similarly, the waveform signal at the time of the operation and the presence or absence of continuation are stored in the storage area of the storage means corresponding to the manual operation means. Next, when one of the manual operation means for calling designation is operated, the stored waveform signal and the presence / absence of continuation are called from the storage area of the corresponding storage means. Output continuously from the output means. If the continuation is not stored, a different waveform signal is output in a predetermined order from the waveform signal.

(E) Example Hereinafter, the present invention will be described in more detail with reference to examples.

FIG. 1 is an external perspective view of a low frequency treatment device showing one embodiment of the present invention. This low frequency treatment device includes a main body 1 and
The main body 1 is composed of a pair of conductor electrodes 2 and 3 connected by lead wires 2a and 3a. On the side of the main body 1,
An output adjustment dial 4 also serving as a power switch is provided. Further, on the outer surface of the main body 1, a continuation / restart switch 5, a memory (M ₁ ) switch 6 _-1 and a memory (M ₂ ) switch 6
_-2 , and a memory (M ₃ ) switch _6-3 .

FIG. 2 is a block diagram showing a circuit configuration of the low frequency treatment device according to the embodiment. In the figure, a voltage from a power supply (battery) 9 is supplied to each part of the circuit via a power switch 4b of an output adjustment volume 4a with a power switch 4b. Continue / Resume switch 5, Memory switches _6-1 and 6
_-2, the ON signal of _6-3 is adapted to be received by the control circuit (MPU) 10.

The control circuit 10 has a function of sequentially outputting low-frequency pulse signals having different waveforms in a predetermined order by the power switch 4bON.

The continuation / restart switch 5 is used when a desired waveform signal is to be continued during the sequential output of the low frequency pulse signal, and when it is desired to return to a different waveform signal again during the continuation.
Each switch is operated. Memory switch 6
_-1 , 6 _-2 , and _6-3 respectively designate memories m ₁ , m ₂ , and m ₃ built in the control circuit 10 and store the waveform signal at the time of operation and the presence or absence of continuous output in the corresponding memories. The switch is operated to call out the waveform signal stored from the corresponding memory and the presence / absence of continuation.

Each waveform signal output from the control circuit 10 is
, Output adjustment volume 4a, output circuit (+) 1
2. Conductor electrode (therapeutic electrode) via output circuit (-) 13
It is applied to a few sites so that stimulation is given to the treatment site of the human body.

Next, the operation of the low frequency treatment device of the above embodiment will be described with reference to the flowcharts shown in FIGS. 3 (A) and 3 (B).

<Continuous Output of Different Waveform Signals> When the user turns on the power switch 4b with the lead electrodes 2 and 3 set at the treatment site, the MPU of the control circuit 10
Initialize [(hereinafter abbreviated as ST) Step ST 1], then the memory switch _{6-1, 6-2, 6-3} determines whether or not pressed (ST2, ST3, ST4). Start the user at the time of a memory switch _{6-1, 6-2,} while pressing the one of _6-3, the determination of when not power switch 4 is NO, and the a "0" to Repitofuragu, Wave No Is set to 1 (ST5). Here, the repeat flag stores the repetition state as “1” and the non-repetition state as “0”. Wave No.
Are the waveform numbers when different waveforms are repeatedly and sequentially output as shown in FIG. 4 (A). Since the continuation is not specified, the output of the treatment pulse is started in the order shown on the waveform signal output side of FIG. 4A (ST6). And
The timer Time is set to 5 seconds (ST7). This timer Time
Defines the period during which the same waveform signal is output, and is decremented as time elapses after the setting. Thereafter, whether to continue / restart switch 5 is depressed (ST11), the memory switch _{6-1, 6-2,} whether any of _6-3 is pressed (S
(T12, ST13, ST14), and it is further determined whether or not the timer Time has become 0 (ST15).

If none of the switches is pressed before 5 seconds have elapsed, the determination of “Timer Time = 0” in ST15 becomes YES after 5 seconds, and the timer Time is reset to 5 seconds here (S
T16) Then, it is determined whether or not the repeat flag is 0 (ST1).
7). Since the continuation switch has not been pressed, this judgment is Y
ES, the wave number is incremented by 1 and the next waveform, that is, the waveform signal of No. 2 following No. 1 in the example of FIG. 4A is output (ST18). Then, returning to step ST11, if none of the switches is pressed, ST11 to ST11 are executed.
The processing of ST18 is repeated, and as shown in FIG.
Output different waveform signals in the order of o.1 → No.2 → No.3 → No.4 ...

<Continuous output and stop of specified waveform> When the user feels a desired waveform signal while sequentially outputting different waveform signals and presses the continue / restart switch 5, the determination in ST11 becomes YES, and then the same waveform is output. It is determined whether or not the signal is in the repeated output state (ST19). If the signal is not in the repeated state, the fact that the signal is in the repeat state in the memory is stored as "1" (ST20). The non-repeated state “0” is stored (ST20).
In this case, for example, as shown in FIG. 4 (B), the waveform of the No.3 continuation / resumption switch 5 is pressed at time t ₁ in the output, the output waveform signal of the No.3 is continuously Is done. That is, when 5 seconds have elapsed since the start of the continuous output operation, the determination in ST15 becomes YES, and the timer Time is reset to 5 seconds in ST16.
Is NO since the repeat flag is set to "1", the process returns to ST11 without changing the waveform, and the processes of ST11 to ST18 are repeated thereafter. In the example of FIG. The output of the waveform signal is continued as it is.

If the user wants to cancel this during the continuous output, the continuation / restart switch 5 is pressed again. This makes the determination of ST11 YE
In S19, it is determined again whether or not the state is the repetition state in ST19. Since this is YES, the repeat flag is set to "0" (ST21). After 5 seconds have elapsed, and when the timer Time has expired, the timer Time is reset to 5 seconds with the determination YES in ST15 (ST16), and it is determined whether the repeat flag is 0 (ST17). , The determination is YES because the repeat flag is "0", and the waveform No. is changed to the next No. 4 and output (ST18). Thereafter, different waveform signals are sequentially output. In time t ₁ in FIG. 4 (C), specifies the continuation shows the waveform signal when releasing the continuation at t _2.

<Storage and Recall> Next, a case where a desired waveform is stored will be described.
First, when a waveform signal desired by the user is output during the sequential output of different waveform signals, for example, the memory switch 6 _-1 is output.
Press, ST12 of "M ₁ pressed or" decision is YES, stores the contents of Repitofuragu the RF ₁ of the memory m _1, the wave No. in the waveform output of the memory m ₁ N
o.1 (ST22). While the continuation / resumption switch 5 is not pressed, the memory switch _6-1 is pushed, as RF ₁ "0" is stored. Instead of the memory switch _6-1 stores the memory switch _6-2 or _6-3 is in the same way each memory m ₂ or m _3, even when pressed in Repitofuragu content and Wave No. (ST23, ST24 ).

Also, if the continuation / restart switch 5 is pressed once and the desired waveform is continuously output, for example, if the memory switch _6-1 is pressed, the repeat flag and the wave No.
There is stored in the memory m _1. Further, in this case, the repeat flag is “1”.

Next, when calling and outputting the waveforms stored in the memories m ₁ , m ₂ , and m ₃ , for example, when outputting a waveform signal having the contents of the memory m ₁ , _hold down the memory switch 6-1,
Turn on the power switch 4b. As a result, the determination of ST2 becomes YES
Then, the waveform signal of RF ₁ and No. _{1 in} the memory m ₁ is read out and stored in the repeat flag and the wave No. (ST8). The cash Waniri memory switch _6-1, the memory switch _6-2 or _6-3 power switch 4b enters in a state of being pressed Similarly, if the memory m _2, or RF ₁ of m _3,, No.2 or RF _2. Read No. 3 and store it in the repeat flag and wave No. (ST9, ST10).

Power switch 4b with memory switch _6-1 pressed
, The treatment pulse output is started following the reading process of ST8 (ST6). RF ₁ stored in memory m ₁ is “0”
When No. 1 is "3", different waveform signals are sequentially switched from the No. 3 waveform every 5 seconds as shown in FIG. 4 (D) in the processing of ST5 to ST7 and ST11 to ST18. (No.3 → No.4
→ No.5 → No.1, ...). Further, it stored in the memory m _1. If RF ₁ is “1” and No. 1 is “3”, ST5 to ST7, ST11
As shown in FIG. 4 (E), the No. 3 waveform signal is continuously output in the processing of steps ST18 to ST18.

When the contents stored in the memories m ₁ , m ₂ and m ₃ are to be changed, the continuation / reclosing switch 5 and the memory switches _6-1 , 6 _-2 and _6-3 are appropriately operated to change the contents. What is necessary is just to overwrite and store in m ₁ , m ₂ and m ₃ .

Further, in the above embodiment, when storing the waveform signal in the memories m ₁ , m ₂ , and m ₃ , the memory switch 6 is output during the output of the waveform signal.
_{-1, 6-2, 6-3} to select operating one of the memory switch _6-1 to call the stored waveform signal, _6-2, in the state that the selection operation of one of _6-3 Although the power switch is turned on, that is, both the switch for storage and the switch for recall are used. However, in some cases, the switch for storage and the call for recall may be separately provided.

(F) Effect of the invention According to the invention, a plurality of waveform signals are stored in the storage means and a plurality of manual operation means are provided for recall, so that a plurality of waveforms are stored at any time, And can be called. Also, after calling and outputting the stored waveform signal, if the user wants to use another waveform and presses the continuation / public switch (manual operation means for identifying the waveform signal) to stop the continuation, the storage means is not cleared. As long as the next time the treatment is performed, the stored waveform signal can be called up. Also, after turning on the continuation switch, the memory switches _6-1 , 6 _-2 , 6
_If you press _-3 (manual operation means for specifying storage) and store it, the stored waveform will be output continuously when called, but if the continuous switch is not turned on, the waveform at that time will be stored in the storage means. When called out, the stored waveforms can be output in time sequence. There are advantages such as.
