[Technical field to which the invention belongs]

 The present invention relates to a battery-type electric potential therapy device that can adjust the output voltage level of a high-frequency high-frequency pulse output from a battery-type electric potential therapy device with high accuracy and high resolution according to a user's request. is there.

[Prior art]

 An electric potential therapy device is a type of home therapy device that applies electric energy to the human body. This electric potential therapy device is a device for treating a human body by applying a high potential by placing the human body in an AC electric field, a DC electric field or an insulated state. By applying a negative potential of 10,000 V, the amount of ionized sodium and calcium in the circulating blood increases, so that the acidified human body can be alkalized. Although this potential therapy device uses a high potential, it is excellent in safety because no current flows to the human body even when it is grounded.

A battery-type potential therapy device, which is a kind of such a potential therapy device, has improved portability and portability by using a battery as a power source, and has a battery (eg, a plurality of dry batteries). When a bias voltage is applied to the primary side of a step-up transformer from a power supply unit composed of a power source, the high-voltage pulse generated on the secondary side of the step-up transformer is converted into a high-voltage pulse having a negative potential, and the high-voltage pulse having the negative potential is converted to an electrode The unit is configured to output to the treatment site.

[0004] Potential treatment using this battery-type potential treatment device includes systemic treatment using an electric floor plate and partial treatment using a treatment needle. In partial treatment using a treatment needle, the treatment needle is brought into direct contact with the skin. As the output voltage level is higher, the user will feel more tingling because of the treatment performed. There are more people who feel uncomfortable with "tizziness" than those who like to experience this "tizziness", and because the individual differences in "tizziness" are very large, the level of "tizziness" bodily sensation The probability of the presence of the same person is extremely low, and even for the same person, the sensation level of "piri sensation" varies depending on the treatment site, and for example, particularly in a sensitive part of the skin, the stimulation is particularly strong. Therefore, in order to cope with the tingling sensation with a large variation factor as described above, the output voltage level of the high-voltage pulse having a negative potential output from the battery-type electric potential therapy device is adjusted with high resolution and high accuracy. There is a need. In the whole body treatment using the electric floor plate, the electrode part of the electric floor plate does not come into direct contact with the skin, so that high resolution is not required as in the partial treatment using the treatment needle described above. Since the tendency of power-up by increasing the output voltage level of the battery-type potential therapy device is becoming remarkable, it is desirable to be able to finely adjust the output voltage level from the upper limit to the lower limit.

[0005] As a method of adjusting the output voltage level in the battery type electric potential therapy device, a variable resistor (volume) or a slide switch is provided between a power supply voltage end of a power supply unit and a primary side of a step-up transformer. An adjustment method is common.

[0006]

[Problems to be solved by the invention]

 When the output voltage level adjustment method using the above-mentioned variable resistor is adopted, since the adjustment operation by the user is interposed, the output voltage level is adjusted in an analog manner, and the resolution is not constant. Accuracy cannot be obtained. On the other hand, if an adjustment method using a slide switch is adopted, the output voltage level can be digitally adjusted to improve the adjustment accuracy. If a corresponding small slide switch is used, the number of contacts that can be switched is at most about four, so that high resolution cannot be realized.

The present invention solves the above-mentioned problem by enabling the output voltage level of a high-voltage pulse having a negative potential output from a battery-type electric potential therapy device to be adjusted with high precision and high resolution. Aim.

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a circuit diagram showing the configuration of the battery-type potential therapy device according to the first embodiment of the present invention. In FIG. 1, reference numeral 1 denotes a power supply unit composed of a battery. The power supply unit 1 includes a plurality of batteries (for example, when the power supply voltage is 6 V, a 1.5 V dry battery (1)) connected to a desired power supply voltage. (A secondary battery) connected in series, but a secondary battery such as a Ni-Cd battery may be used instead), which is the energy source of the high-voltage high-frequency pulse to be generated. .

A power supply voltage terminal of the power supply unit 1 is connected to an input terminal of the voltage drop unit 2 and a signal processing unit 3, and an output terminal of the voltage drop unit 2 is connected to an intermediate terminal of the primary winding 5 of the step-up transformer 4. It is connected to the tap 5a. The signal processing unit 3 includes an input unit 6 for inputting output voltage level adjustment information to be described later, a clock pulse generation unit 7 for generating a clock pulse, and each control input terminal of the voltage drop unit 2. It is connected.

The signal processing unit 3 is further connected to a switching unit 8 including a resistor Rs and a transistor Qs connected to the resistor Rs. The emitter of the transistor Qs is grounded, the collector of the transistor Qs is connected to the tap 5b of the primary winding 5 of the step-up transformer 4, and a capacitor is connected between the taps 5b and 5c of the primary winding 5 of the step-up transformer 4. C1 is connected. The switching unit 8 is configured to continuously open and close a connection point (a ground connection point) between the tap 5b of the primary winding 5 of the step-up transformer 4 and the capacitor C1 according to a switching pulse input from the signal processing unit 3. Has a function.

In the present embodiment, the voltage drop unit 2, the signal processing unit 3, the input unit 6, the clock pulse generation unit 7, and the switching unit 8 are configured as one application-specific integrated circuit (ASIC). As a result, cost reduction and miniaturization have been realized by reducing the number of parts. Note that, instead of using an ASIC as described above, an IC or the like may be combined.

The anode of the diode D11 and one end of the capacitors C2 and C3 are connected to the intermediate tap 9a of the secondary winding 9 of the step-up transformer 4, and the capacitor C3 is connected to the tap 9b of the secondary winding 9. Is connected to one end of the protection resistor Rp, and one end of the capacitor C4 is connected to the tap 9c of the secondary winding 9. The cathode of the diode D11 is connected to the other end of the capacitor C4 and the anode of the diode D12. The cathode of the diode D12 and the other end of the capacitor C2 are connected to the grounded electrode 10a. It is connected to the electrode 10b. Here, the capacitors C2 to C4 and the diodes D11 and D12 are connected to the primary winding 5 of the step-up transformer 4 while applying a bias voltage from the power supply unit 1 to the primary winding 5 of the step-up transformer 4 via the voltage drop unit 2. The converter 11 converts a high-frequency high-frequency pulse generated in the secondary winding 9 of the step-up transformer 4 into a high-voltage high-frequency pulse having a negative potential when the ground connection point 5b is continuously opened and closed.

In the present embodiment, the high-frequency high-frequency pulse having the negative potential has a constant of each of the above-described components so that the peak voltage is −300 V to −1000 V and the frequency is 1 KHz to 10 KHz. It should be set (the frequency of 1 KHz to 10 KHz includes a part that cannot be called “high frequency”. However, since the frequency of the output signal of our conventional electrotherapy device is about 50 Hz, We will call it "high frequency.")

The voltage drop unit 2 includes a plurality of parallel-connected current paths L 1 to Ln having switching elements that are opened and closed by the signal processing unit 3, output terminals of switching elements of the current paths L 2 to Ln, and a booster. It comprises a voltage drop element connected between the primary windings 5 of the transformer 4. Note that the current path L1 is closed only at the time of maximum output, and otherwise opened.

In the present embodiment, the resistors R2 to Rn are used as the voltage drop elements, and a transistor switch is used as the switching element (an FET may be used instead of a transistor). In the transistor switch, for example, the case of the current path L1 will be described. The emitter-collector junction of the PNP transistor Q1 is connected between the power supply voltage end of the power supply section 1 and the current path L1, and the base of the PNP transistor Q1 is connected to a resistor. Connected to the emitter via R11, connected to the collector of an NPN transistor Q10 via a resistor 12, connected to the base of the transistor Q10 via a resistor 13 to the signal processing section 3, and connected to the emitter of the transistor Q10 to ground. And configure. The resistance values of the resistors R2 to Rn are appropriately set so that the combined resistance value of the voltage drop unit 2 can take many values by a combination of opening and closing of the current paths L2 to Ln. Although the emitter-collector junction of the transistor Q1 has a resistance component, this resistance component is assumed to be sufficiently smaller than the resistance values of the resistors R2 to Rn as voltage drop elements.

Next, the operation of the battery-type electric potential treatment device of the present embodiment will be described. FIG. 2 shows that the signal processing unit 3 generates a signal based on a clock pulse from the clock pulse generator 7 in a state where a bias voltage is applied from the power supply unit 1 to the primary winding 5 of the step-up transformer 4 via the voltage drop unit 2. By inputting a switching pulse as illustrated in (a) to the switching 8, when the ground connection point 5b of the primary winding of the step-up transformer 4 is continuously opened and closed, the secondary winding 9 of the step-up transformer 4 Generates high-pressure high-frequency pulses. The high-frequency high-frequency pulse is converted by the conversion unit 11 into a high-frequency high-frequency pulse having a negative potential having a waveform as illustrated in FIG. 2B and output to the treatment site from the electrodes 10a and 10b, thereby performing potential treatment.

In this potential treatment, the user may feel the above-mentioned “tizziness”. In this case, the user operates the output reduction operation by pressing at least once the switch (output down switch if the output up switch and output down switch are provided) provided on the battery type electric potential therapy device to adjust the output voltage level. The input unit 6 sends output voltage level adjustment information to the signal processing unit 3 in response to this operation. Upon receiving the output voltage level adjustment information, the signal processing unit 3 sets any one of the current paths L2 to Ln in a preset combination so as to obtain a voltage drop amount determined by the output voltage level adjustment information. Close more than one book.

For example, in the configuration of FIG. 1, when four current paths L1 to L4 and resistance values of R2 to R4 are 200Ω, when only the current path L2 is closed, the combined resistance value of the voltage drop unit 2 Becomes 200Ω, the combined resistance value becomes 100Ω when the current paths L2 and L3 are closed, and the combined resistance value becomes about 66.7Ω when the current paths L2, L3 and L4 are closed. The amount of descent can be adjusted step by step. By the stepwise adjustment of the amount of voltage drop, the output voltage level of the high-voltage high-frequency pulse output from the electrode units 10a and 10b can be adjusted with high precision and high resolution as desired. Therefore, the user can adjust the output voltage level to his / her own by repeating the output reduction operation until the user does not feel the above-mentioned “tizziness”.

The information on the output voltage level adjusted as described above is stored in a storage device in the apparatus, so that the output voltage level suitable for use by the same user is maintained. I have to. Therefore, the output voltage level may be insufficient when used by another user. In that case, the user can adjust the output voltage level to his / her own by performing an output increasing operation of pressing the output up switch provided on the battery-type potential therapy device at least once.

FIG. 3 is a circuit diagram showing the configuration of a battery-type potential therapy device according to a second embodiment of the present invention. This embodiment is different from the first embodiment shown in FIG. 1 in that the switching elements provided in the respective current paths L1 to Ln of the voltage drop unit 2 are changed from transistor switches to analog switches AN1 to ANn. The other parts are configured in the same manner as in the first embodiment.

According to the present embodiment, the same functions and effects as those of the first embodiment can be obtained.

FIG. 4 is a circuit diagram showing a configuration of a battery-type potential therapy device according to a third embodiment of the present invention. This embodiment is different from the first embodiment shown in FIG. 1 in that (n-1) diodes in which voltage drop elements provided in the current paths L2 to Ln of the voltage drop unit 2 are connected in series from the resistors R2 to Rn. D1 is replaced, and only one of the current paths L1 to Ln is closed, and the other parts are configured in the same manner as in the first embodiment. Note that the voltage drop of the diode is about 0. The value ranges from 3 V to several tens of volts. For example, a diode having a voltage drop of 0.7 V is used as the diode D1 of the present embodiment.

In the present embodiment, the maximum output is obtained when the current path L1 is closed. At this time, the voltage drop due to the resistance component of the emitter-collector junction of the transistor Q1 in the current path L1 is reduced by one of the diodes D1. The predetermined value is about half of the voltage drop per minute. Therefore, when the current path L2 is closed, a voltage drop of one diode D1 occurs in addition to the voltage drop of the transistor, and when the current path L3 is closed, the voltage drop of the diode D1 occurs in addition to the voltage drop of the transistor D1. In the same way, when the current path Ln is closed, a voltage drop of (n-1) diodes D1 is generated in addition to the voltage drop of the transistor, so that any one of the current paths L1 to Ln By closing one or the other, the voltage drop amount of the voltage drop unit 2 can be adjusted stepwise.

According to the present embodiment, the same functions and effects as those of the first embodiment can be obtained.

FIG. 5 is a circuit diagram showing a configuration of a battery-type potential therapy device according to a fourth embodiment of the present invention. This embodiment is different from the second embodiment shown in FIG. 3 in that the voltage drop element is changed from the resistors R2 to Rn to (n-1) diodes D1 connected in series, and the current paths L1 to L1 are changed. Only one of Ln is closed, and the other parts are configured as in the third embodiment.
