The present invention relates to a low frequency and negative potential therapy device which has the functions of a negative potential therapy device and obtains a therapeutic effect by applying a negative voltage of about 00V.

In conventional negative potential therapy devices, negative potential output was obtained by step-up rectifying and smoothing the commercial power supply, but since such conventional examples use a 100V commercial power supply, electronic It is necessary to use large parts, transformers, etc., making it difficult to reduce the size and weight.For this reason, even if it were possible to make a negative potential therapy device also have a low frequency therapy function, it would be extremely difficult to make it smaller and lighter. There was a problem in that it was not possible to obtain a small and simple portable device due to the increase in size.

The present invention has been provided in view of the above-mentioned points, and uses a battery as a power source to reduce the size and weight, and provides low-frequency treatment and negative potential inside a pocket-shaped cliff body. In a low frequency and negative potential therapy device that has completely revised the circuits necessary for both treatment functions, we have made improvements to the output plug and the plug receiver into which the plug is inserted, with the aim of making it even more compact. It is something that exists.

An embodiment of the present invention will be described below, starting with the overall configuration of a low frequency and negative potential treatment device.

In the block diagram of FIG. 1, the timer circuit 13, the oscillation circuit 6, and the primary winding and core of the step-up transformer 1 are shared by the low-frequency pulse generation circuit 40 and the negative potential generation circuit 2. , a timer switching circuit 9, an oscillator switching circuit 10, and a transformer drive switching circuit 11 are provided to switch the operation mode of these circuit parts, and these are connected to a changeover switch 8.
The low frequency pulse treatment mode and the negative potential treatment mode can be switched by interlocking with the . First, in the circuit shown in FIG. 1, the changeover switch 8 is set to the negative potential treatment mode, and the operation display circuit 12 displays that the negative potential treatment is in progress, and the timer circuit 13 is set to the negative potential treatment mode by the timer switching circuit 9. The oscillator switching circuit 10' is set to perform a time-limited operation of 30 minutes per session, and the oscillation circuit 6 is set to an oscillation frequency for negative potential treatment (for example, 50 minutes).
Furthermore, when the output of the oscillation circuit 6 is input to the boosting transformer 1 by the transformer drive switching circuit 11, the secondary output on the negative potential side is input to the negative potential waveform shaping circuit 7. For the state set to
The configuration and operation of the circuit shown in the figure will be explained. The negative potential is generated by a timer circuit 13, an oscillation circuit 6, a step-up transformer, and a negative potential waveform shaping circuit 7. It is configured. In addition, the negative potential output of the negative potential waveform shaping circuit 7 (actually, the output on the body ground side as shown in the circuit example in FIG. 2 described later) is sent via the voltage detection and leakage detection circuit 17 (further via the negative potential output terminal 4). is connected to the negative potential output conductor 18, and this negative potential output conductor 18
A negative voltage is applied to the human body, which is insulated from the earth. The timer circuit 13 is for setting the treatment time, and as mentioned above, the timer switching circuit 9 is configured to perform a time-limited operation of 30 minutes per negative potential treatment, and the operation period of this timer circuit 13 is Oscillation circuit 6 inside
performs oscillation operation. On the other hand, the oscillation circuit 6 has an oscillation frequency for negative potential treatment from the oscillator switching circuit 10' as described above.
For example, it is designed to oscillate at 50Hz, and the output of this oscillation circuit 6 is applied to the primary side of the step-up transformer 1 via the transformer drive switching circuit 11, and the negative potential of the step-up transformer 1 is boosted to about 480V to 660V. The secondary side output of the side is input to the negative potential waveform shaping circuit 7. This negative potential waveform shaping circuit 7 converts the secondary output of the step-up transformer into a smoothing circuit 1.
4, the DC voltage is rectified and smoothed, and the voltage setting circuit 15 sets this DC voltage to a specified voltage value.
By superimposing the alternating current component of the secondary output of the step-up transformer on the above-mentioned direct current voltage, the required negative potential output is generated. It is grounded through the terminal 3, and the negative electrode side is connected to the negative potential output conductor 18 from the negative potential output terminal 4 via the current detection and leakage detection circuit 17. The voltage detection/earth leakage detection circuit 17 has the function of detecting the current flowing through the human body between the negative potential output conductor 18 and the dew detection plate 19 to check the charging state, and the function of checking the charging state between the negative potential output conductor 18 and the earth ground. It has a function of detecting the leakage current flowing due to poor insulation etc. between the voltage detection plate 19 and the negative potential output conductor 18, which is lower than the positive potential of the earth with respect to the negative potential output conductor 18. A positive potential is applied, and the output of the voltage detection and leakage detection circuit 17 activates the voltage detection and earth leakage display circuit 20, which displays the charging status when checking the voltage and the current leakage status when a leakage occurs. Display is performed respectively. Next, when the changeover switch 8 is switched to the lower side in the figure to set the low frequency treatment state, the operation display circuit 12 first displays the low frequency treatment state, and the timer switching circuit 9 also displays the timer circuit 13.
is set to obtain a time limit of 18 minutes for each treatment, and the oscillator switching circuit 10 sets the oscillation circuit 6 to perform oscillation operation at an oscillation frequency arbitrarily set in the range of 1 to 50 Hz. . Thus, as will be described later, the oscillation frequency of the oscillation circuit 6 can be varied by operating the speed adjustment volume knob 32 exposed on the outer surface of the small housing 25.
The output of this oscillation circuit 6 is applied to the primary side of the step-up transformer 1 via the transformer drive switching circuit 11.
The low frequency side secondary output of the step-up transformer 1 of about 0V is sent to the low frequency output conductor 2 via an output adjustment circuit 21 consisting of a variable resistor.
2 is applied to perform low frequency treatment on the human body. Here, the volume knob 33 of the output adjustment circuit 21 is also exposed to the outside of the small crab body 25, as will be described later, so that the strength (peak voltage value) of the low frequency pulse during low frequency treatment can be varied as appropriate. . If the soft start circuit 23 applies a high-power low-frequency output to the low-frequency output conductor 22 at the moment when the low-frequency output conductor 22 comes into contact with the human body, a strong shock will be applied to the human body. Therefore, the output of the oscillation circuit 6 is transmitted to the step-up transformer 1 so that the low-frequency output gradually increases from the time when the human body contact detection circuit 24 detects that the low-frequency output conductor 22 has come into contact with a human body. It is something to control. Note that 5 in the figure is a battery that supplies power to the entire circuit. FIG. 2 shows a concrete circuit example of another embodiment of the present invention. In this embodiment circuit, the oscillation circuit is formed by separating it into an oscillation circuit 6a for negative potential and an oscillation circuit 6b for low frequency. This embodiment has the same circuit configuration as that shown in the block diagram of FIG. 1, except for the point shown in FIG. 3, and a perspective view of this embodiment is shown in FIG.

In the circuit shown in FIG. 2, the timer circuit 13 uses an IC to count the CR oscillation frequency, and when the transistor Tr provided as the timer switching circuit 9 is off, the When the transistor Tr is on, the eye clock operates for 15 minutes/time during low frequency treatment. During the time limit of this timer circuit 13, the transistor Tr2 is activated.

By changing the color of the light emitted from the operation display section 12a, the aforementioned low frequency treatment state and negative potential treatment state are distinguished. In addition, in the circuit shown in FIG. 2, the output section is formed in one place, and the small pupil body 25 is
Low-frequency output terminals 4 are installed as first, second, and third terminals in the plug receiving hole 41 formed on the outside in order from the back.
2. An appliance ground terminal 43 and a negative potential output terminal 4 are arranged, and the earth earth terminal 3 is arranged separately from these in the earth ground plug receiving hole 44. Thus, when the circuit in FIG. 2 is set to the negative potential treatment side, the output of the oscillation circuit 6, which oscillated at an oscillation frequency of 50 Hz as described above, is multiplied by the amplifier 31 and then forms the transformer drive conversion circuit 11. Among transistors Tr4 and Tr5, transistor T
It is input to the primary side of the step-up transformer 1 via r4, and a boosted output voltage is obtained at the secondary winding on the negative potential side.

In the negative potential waveform shaping circuit 7, the output voltage of the secondary winding on the negative potential side of the step-up transformer is rectified and smoothed by the smoothing circuit 14 to obtain a DC output of several hundred volts, which is formed by a series circuit of Jenner diodes. The voltage setting circuit 15 sets the DC output to a specified voltage value, and the waveform synthesis circuit 16 converts the pulse wave of the output of the step-up transformer 1 to the DC output, so that the DC output has a very short energization period (0. 2 to 0.1 seconds), and connect the positive side of this intermittent (repetitive frequency 50Hz) DC output to the ground terminal 3.
This is to set the body ground to a predetermined negative potential output voltage by dropping it to the earth ground through
The negative potential output terminal 4 is connected to the negative potential output terminal 4 through the negative potential output terminal 4, and a negative potential output is applied to the human body insulated from the earth by the negative potential output conductor 18 connected to the negative potential output terminal 4. In addition, the voltage-dividing high resistances R, R2 constitute a part of the voltage detection and leakage detection circuit 17, and this leakage detection function part is as follows:
It is composed of a transistor Tr6 and a light emitting diode LED3 connected in series to the emitter side of the transistor Tr6, and prevents leakage current between the earth ground and the negative potential output terminal 4 due to reasons such as when a human body undergoing negative potential treatment comes into contact with the earth earth. When the current value exceeds a set value set to, for example, 100 A, the voltage divided by the voltage dividing resistors R, R2 becomes approximately 2V, so the transistor Tr6 is turned on and the light emitting diode LE is turned on.
D3 is lit to notify that a leakage current has occurred, that is, there is a defect in the ground. Furthermore, this light emitting diode LED
3 is used to emit red light, and is used to detect abnormal conditions (
It is designed so that the user can reliably sense the occurrence of electrical leakage. On the other hand, the voltage detection function part is composed of a transistor Tr7 different from the above and a light emitting diode LED4 wired in series on the collector side of the transistor Tr7. Obtain low voltage DC output and send it to voltage detection plate 1
9, when a person connected to the negative potential output conductor 18 touches this voltage detecting plate 19, an output of about 1 to 2 V will be generated as the divided voltage output of the divided voltage high resistors R, , R2. As a result, the transistor Tr7 is turned on and the light emitting diode LED4 lights up, indicating that a negative potential is normally generated and the charged state is present. Since this light emitting diode LED is used to indicate that it is in a normal charged state when it is lit, one that emits green light is used.
This is done to prevent misunderstandings. - When the switch 8 is switched to the low frequency side, the timer circuit 1
3 causes the low frequency side oscillation circuit 6b to perform an oscillation operation, and adjusts the variable resistor VR2 provided in this oscillation circuit 6b and connected to the volume knob 32 on the outer surface of the small crab body 25. As a result, the oscillation period of the oscillation circuit 6 is varied from 30 msec to lsec, and the square wave output of the oscillation circuit 6 is differentiated by a differentiating circuit consisting of a capacitor C and a resistor R3, and the pulse period is approximately 0.2 sec to 100 msec. 0

This is for preventing backflow when detecting contact of a human body to the conductor by applying battery voltage to the device ground terminal 43 and the conductor. As described above, the human body contact detection circuit 24 applies the voltage of the battery 5 between the low frequency output terminal 42 and the appliance ground terminal 43, and measures the resistance value between the two terminals 42 and 43 at this time. It is designed to detect whether or not a human body has touched the conductor, and if the low frequency output conductor 22 is now brought into contact with the human body, at this point, the human body contact detection circuit 24 has an output that rises in a step manner. A waveform is obtained. Therefore, the soft start circuit 23 integrates the output signal of the human body contact detection circuit 24 as described above with an integrating circuit section 45 consisting of a resistor R4 and a capacitor C2, and gradually increases the output signal from 2 to $e from the time of the human body contact.
By creating a voltage signal that rises over a period of approximately c and applying it to the drain D of the field effect transistor FET, the transistor Tr8 is
