When a call switch 6 is turned on, wave-form signals are outputted in the stored wave-form sequences, and the wave-form signals are repeatedly outputted unless the call switch 6 is again turned on. A realignment switch 7 is turned on to realign the selected wave-forms according to the preset rule. Only the wave-forms giving comfortable stimulation can freely be selected.

Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application This invention relates to a low frequency treatment device, and particularly to a low frequency treatment device that allows a user to select different combinations of waveform signals.

(B) Prior Art In general, a low-frequency treatment device is equipped with a plurality of conductor electrodes (for example, one pair), and applies a low-frequency signal to the affected area by applying these conductor electrodes to the affected area. In this type of low frequency treatment device, the low frequency signal applied to the conventional conductor electrode is
There are those that repeatedly output a single waveform signal, and those that output waveform signals of various modes with different frequencies and combinations of continuous/intermittent, etc. in a predetermined order. Furthermore, a device has been proposed in which the waveform signal at the time of key operation is fixed and continuously outputted (Japanese Patent Application No. 1-88404). Briefly explaining this low frequency treatment device, when the continuation/resume switch SWI shown in FIG. 8 is pressed once, the same waveform signal at the time of the operation is repeatedly output. After that, when the switch sw is pressed again, the waveform of the next waveform number is output. When outputting your favorite waveform signal, switch S.
Operate W1 again and turn off the power switch sw2. Thereafter, when the power switch SW2 is turned on, the memorized waveform signal is output.

(c) Problems to be solved by the invention In the conventional low frequency treatment device described above, a single waveform signal is
Or because it is a predetermined combination of waveform signals,
Even if users did not like it, they had no choice but to accept it as long as they used it.

In addition, although the low-frequency treatment device according to the above-mentioned prior application can select and use a favorite waveform signal, it is a continuation of that waveform signal, and the user cannot arbitrarily select, store, and recall multiple types of waveform signals. There wasn't. Moreover, it is of course impossible to output the plurality of waveforms selected by the user in any order.

The present invention has been made in view of the above-mentioned problems, and allows a user to select a desired waveform signal from among a plurality of types of waveform signals, and output only the selected waveform signals in a predetermined order. The purpose is to provide low frequency treatment equipment.

(d) Means and operation for solving the problem The low frequency treatment of the present invention is a low frequency treatment that uses a pair of conductor electrodes and sequentially applies and outputs a plurality of types of signals with different wave forms to the conductor electrodes. In the device, while sequentially outputting the plurality of types of signals,
a selection switch that selects a desired signal when operated during output of a desired signal; a storage means that stores the signals sequentially selected by the selection switch; and a storage means that stores the signals that are sequentially selected by the selection switch; and output means for sequentially outputting.

When using this low-frequency treatment device, when the user sets the conductor electrode on the treatment site and turns on the power switch, waveform signals of different frequencies, for example, are sequentially output. If the user operates the selection switch when the waveform signal is favorable from the applied stimulus, the type of the waveform signal is memorized. Similarly, when a selection switch is operated when a desired waveform signal is selected among several output waveform signals, the type of the waveform signal is sequentially stored. Then, at the time of re-output, only the stored waveform signals of the user's preference are output in the order of input or according to a predetermined rule.

Therefore, each user can freely and comfortably perform treatment according to his or her preference, excluding waveform signals that he or she dislikes.

(E) Examples The present invention will be explained in more detail with reference to Examples below.

FIG. 1 is an external perspective view of a low frequency treatment device showing an embodiment of the present invention. This low frequency treatment device is composed of a main body part and a pair of conductor electrodes 2.3 connected to the main body part 1 by lead wires 2a and 3a. An output adjustment dial 4 that also serves as a power switch is provided on the side surface of the main body 1. Furthermore, a selection switch 5, a call switch 6, a rearrangement switch 7, and a smoothing switch 8 are provided on the outer surface of the main body 1.

FIG. 2 is a block diagram showing the circuit configuration of the low frequency treatment device according to the embodiment. In the figure, voltage from a power source (battery) 9 is supplied to each part of the circuit via a power switch of an output adjustment volume 4a equipped with a power switch. Each ON signal of the selection switch 5, call switch 6, rearrangement switch 7, and smoothing switch 8 is taken into a control circuit (MPLJ) 10.

Control times! l@10 has a function of sequentially outputting low-frequency pulse signals with different frequencies shown in the table below when the power switch is turned on, and also has functions described later.

<Table> The selection switch 5 is a switch operated when it is desired to memorize the waveform currently being output, and the recall switch 6 is a switch operated when outputting the memorized waveforms in order. The switch is operated following the operation of the call switch 6, and the switch is operated according to a predetermined rule (priority order).
The smoothing switch 8 is a switch for rearranging and outputting the waveforms stored according to the
Alternatively, it is a switch that follows the rearrangement switch and is operated to smooth sudden changes between individual waveforms in the stored waveform group and output the same.

The control circuit 10 has a function of storing the waveform (type) at the time of the operation in a memory in response to the operation of the selection switch 5;
A function for outputting the waveform signals stored in the memory in the order of storage in response to the operation of the recall switch 6, and a function for rearranging the waveform signals stored in the memory in the order of priority in response to the operation of the rearrangement switch 7. In response to the operation of the smoothing switch 8, it has a function of smoothing and outputting the changes at the time of switching between each waveform.

Each waveform signal output from the control circuit 10 is transmitted to the booster circuit 1.
1, the output adjustment volume 4a, the output circuit (+
) 12 and an output circuit (-) 13 to the conductor electrodes (therapeutic electrodes) 2.3 so as to provide stimulation to the treatment site of the human body.

Next, the waveform selection and output operation of the low frequency treatment device of the above embodiment will be explained.

When the user turns on the power switch with the conductor electrode 2.3 set on the treatment site, the control circuit 10 outputs each waveform signal at a, b, . . . 11 ++B in the above table. The user can obtain a desired stimulus from among the waveform signals outputted after one song, and when the selection switch 5 is turned on at that point, the type of waveform being outputted at that point is memorized. As an example, if the user selects his/her favorite waveform signals in the order of i, d, and h, the types of waveform signals are stored in the memory in the order of b, d, and h. Next, when the calling switch 6 is turned on, the waveform signals are output from the control circuit 10 in the order of the stored waveforms, that is, in the order of ``s'', ``d'', and ``h''. The output waveform is shown in FIG. 3(a).

Again, unless the call switch 6 is ONL, b, d, h
The waveform signal is repeatedly output. The waveform selected by the selection switch 5 is determined by a predetermined rule (priority order).
When rearranging and outputting according to the following, the rearrangement switch 7 is turned on. In the example where the user memorizes s, d, and h in this order, the 4S precedence order in the table above is d, h, and b, so the waveforms are output in this order. The output waveform is shown in Figure 3 (+
)) Shown in the tail. Further, as a priority order other than the above table, for example, the signals may be output in order of low frequency and high frequency. In an example in which the user memorizes s, d, and h, the waveforms output in descending order of frequency are shown in Figure 3 (C), and conversely, the waveforms output in order of high frequency are shown in Figure 3 (d).
).

Next, smoothing of the output waveform will be explained.

As shown in the output waveform side of Figure 3(a) above, waveforms b and d
, h are selected and these waveforms are sequentially output, as shown in FIG. 4(a), the frequency change when switching from b to dSd to h is severe. Therefore, if a gradual change is desired, the smoothing switch 8 is operated following the operation of the calling switch 6. In response to this operation, the control circuit IO changes the frequency from b (10Hz) to
201 during switching from d (50Hz), a little bit at 30Hz, and even when switching from d to h, 30s, 20Hz
, 10Hz, and 5Hz signals are input, and a smoothed waveform is output. The output waveform is shown in FIG. 4(C).

The frequency change of the waveform output according to the predetermined priority order of FIG. 3(b) is shown in FIG. 5(a). If the frequency changes are smoothed as shown in FIG. 5(b), the output waveform will be as shown in FIG. 5(c).

Similarly, the waveforms rearranged in descending order of frequency shown in Fig. 3(C), and the frequency changes in b and d, are shown in Fig. 6(a), but this is shown in Fig. 6(b). As shown, if smoothed, the output waveform will be as shown in Figure 6 (C), and the frequency changes of waveforms d, b, h shown in Figure 3 (d) rearranged in descending order of frequency are as follows: , as shown in FIG. 7(a), and if this is smoothed as shown in FIG. 7(b), the output waveform will be as shown in FIG. 7(C).

According to this embodiment of the low-frequency treatment device, by using the selection switch, you can freely select only the waveforms that give you pleasant stimulation, and by operating the rearrangement switch and the smoothing switch, you can select, for example, a low frequency waveform. By rearranging them in this manner and smoothing the changes, it is possible to reduce the impact caused by sudden changes.

Note that in the above embodiments, the duration, pulse width, and peak value of the waveform are not particularly determined; however, if the duration, pulse width, peak value, etc. of the waveform differ depending on the individual waveforms, these differences may be considered in the selection. All you have to do is rearrange or smooth the waveforms.

In addition, as a means for making the user feel that the output waveform changes smoothly from one waveform to the next in the order in which the selected waveforms are arranged, the frequency is changed in the above embodiment. However, the present invention is not limited to this; for example, the pulse width may be changed or the peak value of the waveform may be changed.

(f) Effects of the Invention According to the invention described in claim 1, the user can select and store the desired waveform from among a plurality of types of waveforms using the selection switch and output the waveforms in the selected order. You can exclude unnecessary waveforms and output only the waveforms you like in the order you like.

According to the invention as claimed in claim 2, since the waveforms selected by the selection switch can be rearranged and output according to a predetermined rule, for example, by rearranging the frequencies in an increasing direction or a decreasing direction, the frequencies can be arranged in an uneven manner. It is possible to prevent the impact caused by the change.

According to the third aspect of the invention, when outputting some waveforms selected by the selection switch, changes between each waveform,
For example, the frequency can be smoothed so that the user is not shocked by sudden changes between individual waveforms, resulting in smooth changes in stimulation.
