DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a compact low frequency treatment device of the present invention will be described below with reference to the drawings. A first embodiment of the low frequency treatment device of the present invention is shown in FIG. In FIG. 1, the power supply unit (1) is connected to one end of the coil (3), and the other end of the coil (3) is connected to the collector of the transistor (5) and the anode of the diode, respectively. The emitter of the transistor (5) is connected to the negative side of the power supply section (1). Output end (c) of drive pulse (c) output from signal processor (2) is on the base
Are connected.

The cathode of the diode (4) is connected to one end of the capacitor (6), and the emitter of the transistor (7) connected to the collector of the transistor (7) is connected to one end of the depolarizing section (8) and the conductor. It is connected to the child (a). The other end of the depolarizing part (8) is connected to the minus side of the power supply part (1), the other end of the capacitor (6) and the indifferent conductor (b). At the base of the transistor (7), the output terminal of the signal processor (2) that outputs the drive pulse (d)
(d) is connected.

The boosting pulse generating means in the present invention has a function of intermittently generating a boosting pulse having a predetermined boosted voltage with respect to the voltage of the input pulse which is intermittently input. It may have any structure as long as it has an inductance component such as a drive drive transistor 5 and a coil 3 as shown in FIG. In response to the Faraday principle, a circuit that generates a counter electromotive force is used.

The circuit having the inductance component in the boosting pulse generating means in the present invention may be a single coil or may be a combination of a plurality of coils. Also, the coil may function as a transformer. The power supply unit (1) is made up of coin-type, cylindrical-type, ultra-thin, pin-type, etc. microbattery batteries, and the smallest battery that can be actually used is preferable, but in general, IC cards, memory cards, watches, etc. are handy-typed. Any device can be used as long as it is used for the equipment.

A signal processor (2) which is a signal processing means.
Outputs at least two drive pulses whose pulse width and / or pulse interval can change over time according to a predetermined program. The signal processor (2) is provided with an input terminal (9) for artificially setting the output mode and a clock pulse generator (10). The depolarizing section (8) in the present invention is a means for neutralizing the polarization charge generated in the stimulated body when the electrical stimulation is applied to the living body. For example, the depolarizing section (a) is related to the rest period of the applied pulse. And if the indifferent element (b) is short-circuited, the polarization state becomes a polar neutralization state. This means for short-circuiting also means connecting a resistor or a switching transistor or the like that is turned on during the rest period of the applied pulse between the gate and the gate.

Further, not only is the depolarization section (8) set to the portion shown in FIG. 1, but when depolarization is performed, polarization is obtained by connecting a gate conductor or a non-gate conductor to the power supply section (1). The charge may be neutralized. That is, the power supply in the present invention is
It uses a so-called micro battery such as a button battery or a seat battery. Therefore, the internal impedance is extremely small, and the output voltage is 1.5 to 3 V, so it is output as a low-frequency stimulation pulse between the gate and the gate.
Compared with a voltage of 50 to 100 V, it becomes "0" approximately, and the power supply is equivalent to a short-circuited state.

When the power source section (1) is used for depolarization, if the battery is a secondary battery, the current flowing at the time of depolarization can be recovered and used again. The depolarizing part (8) having various forms as described above is appropriately selected according to the usage situation. Next, the operation of the circuit configuration diagram shown in FIG. 1 will be described with reference to FIG. The output waveform of the drive pulse (c) output from the signal processor (2) in FIG. 1 outputs a rectangular wave pulse shown in FIG. 4 (i).

The frequency of the pulse shown in FIG. 4 (i) is preferably, for example, several kHz to several tens of kHz, and the pulse turns on / off the transistor (5) and turns on / off the transistor (5). In the coil (3), due to the back electromotive force generated by Faraday's law, an output pulse having a voltage higher than the voltage of the pulse input intermittently occurs intermittently as shown in FIG. 4 (ii), It is input to the cathode of the diode (4).

That is, in the present invention, the value of the electromotive force generated in the coil 3 changes because the current flowing in the coil 3 changes depending on the ON / OFF time of the transistor 5. Therefore, the boosted pulse voltage changes depending on the size of the pulse interval and pulse width shown in FIG.

On the other hand, a drive pulse (d) as shown in FIG. 4 (iv) is output from the output terminal (d) of the signal processor (2). Transistor (7) by this drive pulse
Turns on and off. When the transistor (7) is turned off, the capacitor (6) accumulates the above-mentioned intermittently output boosting pulse shown in FIG. 4 (ii), and the terminal voltage of the capacitor (6) is shown in FIG. 4 (iii). Like, for example, 5
A voltage value of 0 to 100 V is displayed. When the transistor (7) is turned on, this accumulated pulse is applied to the human body load (RZ) via the conductor (a) as shown in FIG. 4 (v). Next, when the transistor (7) is turned off, the electric charge polarized to the human body load (RZ) is discharged and consumed through the depolarizing means (8).

Therefore, at the same time as the capacitor (6) accumulates at the pulse interval of the transistor (7), the discharge amount of accumulated energy can be controlled by adjusting the pulse width of the low frequency pulse. In the embodiment, it is possible to change the width or period of the low frequency stimulation pulse depending on the pulse width of the drive pulse output from the signal processor (2) or the pulse interval.

Next, the signal processor according to the present invention is preferably constructed by using an IC mainly including a gate array. One example of the configuration of a suitable signal processor according to the present invention is shown in FIG. 16 and its configuration and operation will be described below. (16 G) is the inside of the signal processor. Reference oscillator (16
The oscillation pulse of 1) is connected to the 1 / N1 frequency divider (164), the 1 / N2 frequency divider (165), the 1 / N3 frequency divider (166) and the counter (163), respectively.

1 / N1 frequency divider (164) and 1 / N2 frequency divider (16
5) is connected to the selection means (167). Selection means (167)
Is connected to the monostable oscillator (169), and the output end (16c) of the monostable oscillator (169) is the output end of the drive pulse (c) of the signal processor (16G). The selection means (167) is a 1 / N1 frequency divider (164) and a 1 / N2 frequency divider (1
Any one of 65) is connected to the monostable oscillator 169, and it has a function of selecting it by an external input signal (K-2).

The monostable oscillator (169) has a function of outputting a pulse having a pulse width set by the external input signal (K-3) to the output end (16c) according to the output signal of the selecting means. 1
The output of the / N3 frequency divider (166) is input to the selection means (168), and a pulse having a pulse width determined by the external input signal (K-4) is output as a drive pulse (d). The selection means (168) has a function of selecting a plurality of external input signals (K-4), and the control means (168).
2) Select an arbitrary external input signal.

The counter (163) counts the oscillation pulses of the reference oscillator (161). When the signal of the external input signal (K-1) is input to the control means (162), the control means (162)
The start signal is input to the counter (163). The count value of the counter (163) is input to the control means (162),
The control means (162) controls the reference oscillator when a predetermined value is reached.
The signal to stop the oscillation is output to (161).
The start of signal output of the reference oscillator (161) depends on the control signal output by the control means (162) when the external input signal (K-1) is input. (1610) is an inverter, the output signal of which outputs a voltage of a level for turning on / off the transistor.

The reference oscillator (16 G) of the signal processor (16 G)
As for the frequency of 1), if the drive pulse (c) is 10 kHz and the drive pulse (d) is about 10 Hz, a frequency of about 20 kHz is sufficient for the operation as a low frequency treatment device. Since such a drive pulse is generated by dividing each of the reference pulse signals, if a drive pulse having another specific pulse interval or pulse width is desired to be generated, add a frequency divider. It is satisfactory.

Further, although the signal processor shown in FIG. 16 is configured to generate each drive pulse separately, it may be configured to coordinate the timing between them. For example, if the drive pulse (c) is further counted by a counter and the drive pulse (d) is output at a predetermined count value is additionally provided, and if a selection signal from the input is appropriately selected, the pulse mode Can be expanded.

The operation of the signal processor (2) of the present invention having the above structure will be described. The reference oscillator (161) shown in FIG. 16 corresponds to the clock pulse generator (10) shown in FIG. 1, and the input (9) shown in FIG.
Is the external input signal (K-1) (K-2) (K-3) (K-
It corresponds to 4). However, the external input signal shown in FIG. 16 is not only an artificial input signal, but also functional information input in each component as described later.

The reference pulse output from the reference oscillator is
It is divided into 1 / N1, 1 / N2, and 1 / N3, respectively. Either 1 / N1 frequency division or 1 / N2 frequency division is output as a trigger signal of the monostable oscillator (169) in the selecting means (167). The monostable oscillator (169) receives the trigger signal and outputs the drive pulse (c) from the output end (16c).

The output from the reference oscillator (161) is 1 / N.
The frequency is divided by the frequency divider (166), and the drive pulse (d) is output from the output terminal (16d) through the selecting means (168). The reference pulse of the reference oscillator (161) is counted by the counter (163) by the start signal, and the control means is controlled at a predetermined value.
The signal is output to (162). By this signal, control means (16
2) also has a so-called timer function for sending a stop signal to the reference oscillator 161 to stop the operation of the reference oscillator 161.

Besides, there are other functions such as the inverter shown in (1610) and the selection means (167), (168), which will be described later. As described above, the signal processing means shown in the present invention is a microchip IC having an overall size of several mm2 to several tens of mm2 and a thickness of several mm. For example, an algorithm is a PLD, a gate array, or a standard cell. Representing ASIC
And / or a pulse waveform information of a drive pulse is stored in a storage element in advance, and when outputting, a LUT system that outputs the stored waveform information of the storage element, a microprogram sequencer that generates a drive pulse by a microprogrammed algorithm Etc. are shown.

As described above, according to the present invention, the pulse width and / or the pulse interval of the drive pulse (c) and the drive pulse (d) output according to the algorithm incorporated in the signal processor changes, and various pulse widths and pulse intervals are changed. The low frequency stimulus is output. The frequencies of the first pulse (c) and the second pulse (d) can be 10 kHz for the first pulse (c) and 10 Hz for the second pulse (d).

By the way, the algorithm built in the signal processor also has a function of changing various algorithms to the input information when each information is input from other constituents of the present invention. This is represented as a block diagram as shown in FIG. (A-1) shown in FIG. 3 is the power supply section (1) shown in FIG. 1, and the boosting pulse generation means (A-2) is the coil (3) and transistor (5) shown in FIG. A-
3) corresponds to the capacitor (6), the low frequency stimulation pulse generating means (A-4) corresponds to the transistor (7) shown in FIG. 1, and the depolarizing means (A-7) corresponds to (8). ) Corresponds to (2) shown in FIG. Also, drive pulse (C-1)
And the drive pulse (D-1) correspond to the drive pulse (c) and the drive pulse (d) shown in FIG. 1, respectively.

In FIG. 3, the flow of electric energy is indicated by E and the output is indicated by O. Next, an example of input / output operation of the signal processor (A-5) will be concretely shown and explained in FIG. The signal processor (A-5) receives the voltage information (N-1) from the small battery (A-1) and sends it to the boosting pulse generating means (A-2) by the algorithm corresponding to this information signal (N-1). A drive pulse (C-1) having a predetermined pulse width is output.

That is, when the voltage of the small battery gradually decreases as shown in FIG. 10 (10-i), the signal processor (A-5) produces pulse widths as shown in FIG. 10 (10-iii). The second drive pulse (C-
Output as 1). When the pulse width of the second drive pulse (C-1) becomes large, the boost pulse generating means (A-
The output voltage of 2) becomes large as shown in Fig. 10 (10-iv).
This is because the back electromotive force of the coil (3) in FIG. 1 changes its voltage depending on the time when the coil is energized. For more detailed explanation, FIG. 15 shows an example of a circuit in which the pulse width of the second drive pulse (c) increases as the voltage value of the small battery decreases, and its operation will be described. The battery voltage input section (401) is connected to the anode side of the parallel circuit of the resistor (413) and the diode (402), and the cathode side of the diode (402) is grounded at the other end through the resistor (403). Capacitor
It is connected to one end (410) of (404).

NOT gate (408) having an input terminal (409)
The output of is the input of the NOT gate (407) and the capacitor (4
It is connected to one end (410) of 04). NOT gate (40
The output end (411) of 1) corresponds to the output end (16c) of the drive pulse (c) of FIG. The battery voltage input section (401) is
Corresponds to the external input signal (K-3).

The input end (409) of the NOT gate (408) is

(19-iv) correspond to the output terminals (411), respectively.

When the trigger signal is not input to the input terminal (409), a high level is output to the output terminal (410) of the NOT gate (408) and a low level is output to the output terminal (411) of the NOT gate (407). It is being output. When a trigger signal (high level) is input to the input terminal (409), the NOT gate (40
8) output terminal (410) becomes low level, NOT gate
The output terminal (411) of (407) becomes high level. Next, when the trigger signal (409) goes low, the NOT gate (4
08) output terminal (410) goes high, and the capacitor (4
04) is charged via the battery voltage input unit (401), the diode (402) and / or the resistor (413), and the resistor (403).

The capacitor (404) is charged by the charging current i, the input terminal voltage of the NOT gate (407) gradually rises, and when the threshold voltage is reached, the output terminal of the NOT gate (407).
(411) goes low. Here, the voltage of the battery voltage input section (401) is
The case where the change occurs as in i) will be described.

Initially, when the voltage of the battery voltage input section (401) is high, the resistance (413) due to the charging current i of the capacitor (404)
Since the voltage between the terminals of the battery becomes larger than the forward voltage of the diode (402), the charging current flows from the battery voltage input (401) to the diode (402) and the resistor (413), resistor (403), capacitor (404). Becomes On the other hand, the battery voltage input section (4
When the voltage of 01) decreases and the voltage between the terminals of the resistor (413) becomes lower than the forward voltage, the diode current stops and the charging current i decreases. In this way, as the voltage of the battery voltage input section (401) decreases and the charging current i decreases, the capacitor (4
The charging time of 04) becomes longer (Fig. 19 (19-iii)).

Next, a concrete circuit diagram of the selection means FIG. 16 (168) will be described with reference to FIG. The circuit shown in FIG. 20, the pulse output of the clock pulse generation means (209) is counted by the counter (202), the battery voltage is supplied from the resistance group (210) to a specific resistance according to the count value,
It is a monostable oscillating means composed of the supplied combined resistance, the capacitor (204) and the NOT gates (207) and (205). The input end (201) of the NOT gate (207) is
It is connected to the output terminal of the 1 / N3 frequency divider (166) shown in 16.

The output terminal (206) of the NOT gate (205) is
It is the output end (16d) of the drive pulse (d) shown in 16. The input terminal (206) of the clock pulse generation means (209) is shown in FIG.
This is a part for inputting the external input signal (K-4) shown in FIG. The external input signal (K-4) is, for example, a signal for starting the start of the circuit or a signal for switching the output waveform mode.

Next, the operation of the circuit shown in FIG. 20 will be described. The pulse output from the clock pulse generating means (209) is counted by the counter (202), and the voltage of the level corresponding to the counted value is output as the control signal of the switch group (203). As a result, the battery voltage V 1 is connected to a specific resistance, and a pulse having a width according to the time constant determined by the combined resistance of the resistance to which the battery voltage V is connected and the capacitor (204) is N
It is output from the OT gate (205). That is, the input end (20
When the input of 1) is low level, the output of NOT gate (207) is high level, and when the high level trigger pulse is input to the input terminal (201), the output of NOT gate (207) (208) Becomes low level.

Next, when the trigger pulse (201) becomes low level, the output (208) of the NOT gate (207) changes to the resistance group (2
The capacitor (204) is charged through the combined resistance selected in 10) and gradually rises. Output (2) of NOT gate (205)
06) becomes low level when this voltage reaches the threshold. Therefore, the combined resistance selected from the resistance group (210)
The pulse width of drive pulse (d) can be controlled. That is, FIG.
As shown in (9-iv) and (9-v), it becomes possible to gradually increase or decrease the pulse width,
The sensitivity of the human body can be changed over time. Next, an embodiment in which the drive pulse (c) is controlled according to the stored electric energy of the storage means shown in FIG.

The circuit of the stored electric energy detecting means (309) in FIG. 15 (a) is shown in FIG. 15 (b). A constant voltage diode (312), a trigger diode (313) and a resistor (314) are connected in parallel to a capacitor (306) as a storage means,
1 of the trigger diode (313) connected to the resistor (314)
The end is an output end (k) for outputting a control signal to the signal processor (303).

The control signal output from the output terminal (k) corresponds to the external input signal (K-2) in FIG. 16 and the information input signal (N-2) in FIG. 3, respectively. The boosting pulse is input from the input terminal (e) to the capacitor (306) and charged. At this time, when the voltage between the terminals of the capacitor (306) exceeds the sum of the Zener voltage of the Zener diode (312) and the breakdown voltage of the trigger diode (313), the trigger diode (313) becomes conductive and the output The edge (k) changes from "0" to "1".

The signal processor (303) detects that the output terminal (k) is at a high level, and the selecting means (167) shown in FIG.
Then, the frequency divider provided in the preceding stage is selected to change the period of the trigger signal to the monostable oscillator (169). If the frequency divider selected at this time is to perform frequency division with a long pulse interval, it provides a drive pulse (c) without waste to the boosting pulse generating means as shown in FIG. 9 (9-i). You can

The Zener diode (312) may be omitted in the circuit shown in FIG. 15 (b). In FIG. 3, even when it is desired to set the treatment time only to a predetermined time, the signal processing means (A-5) inputs the start signal (N-3) from the start means (A-6) to drive at the predetermined time. The oscillation of the pulse (D-1) may be stopped. Further, when the start signal (N-3) is input, the drive pulse (D-
1) can also be output as a signal as shown in FIG. 9 (9-v).

The signal processing means (A-5) starts the operation of the depolarizing means (A-7) at the trailing edge of the drive pulse (D-1) (FIG. 17 (17-i)), Neutralize the polarization charge. An example of this concrete circuit is shown in FIG. The circuit of the depolarizing means (308) is shown in Fig. 15 (c). The input (318) is the signal processor (30

The charge of (a) flows out to the indifferent conductor (b). Therefore, when the low frequency stimulation pulse is applied, the polarization charge remaining in the human body load is discharged.

As described above, it is possible to output a signal other than the drive pulse according to the internal algorithm of the signal processing means (A-5). Next, another embodiment in which the pulse energy of the low frequency output pulse is made larger will be described with reference to FIG. The portion shown by the broken line in FIG. 11 is the boost pulse generation means. The negative electrode of the small battery (101) is grounded.

Therefore, the electric energy accumulated in the capacitors (110) and (106) connected in series is output to the conductor (a) via the transistor (109).

At this time, since the capacitors (110) and (106) are connected in series, the low frequency stimulation pulse is output at a voltage twice the voltage accumulated by the boosting pulse.
