Description

[Detailed description of the invention] The present invention relates to a low-frequency treatment device that searches for acupuncture points, so-called acupuncture points, in the human body according to Oriental medicine, and applies low-frequency current optimal for treatment to these acupuncture points.

Even if the acupuncture points, which are generally considered to have the lowest skin resistance and are good conductors, are electrically detected, the electrical conductivity of the acupuncture points is not always the same, and the resistance value may vary due to physical conditions such as muscle fatigue. , which changes depending on the humidity of the skin surface.

Therefore, in order to flow the optimal low-frequency current for treatment, it is necessary to determine the conduction state of the acupuncture point.
Conventionally used acupuncture point search devices and low-frequency treatment devices are each operated separately, and the former applies a low-frequency current to the acupuncture points detected by the latter. If the position of the acupuncture point is likely to shift, low-frequency current is passed without checking the continuity of the acupuncture point, which often results in excessive or insufficient current, and the most suitable current cannot be passed to achieve a therapeutic effect. increased.

The present invention solves the above-mentioned drawbacks, searches for acupoints, and allows the optimal low-frequency current for treatment commensurate with the skin resistance value of the acupuncture points to be applied directly to the acupuncture points.
The present invention provides a low frequency therapy device that can freely convert and adjust the operation time and number of electrical stimulations according to the symptoms and their severity.

The main idea will be explained below with regard to an embodiment shown in the drawings.
As shown in FIG. 1, the low-frequency treatment device of the present invention includes a search circuit 1 for electrically detecting acupuncture points, a time control section 2 for operating time, a frequency adjustment section 3, and an output adjustment section 4. It consists of a system circuit 5, a switching section 6 for switching between the search system circuit 1 and the treatment system circuit 5, and electrode rods 7, 7' connected to the output side of the switching section 6 and supplying low frequency current to the skin. ing.

FIG. 2 is an example of a specific circuit configuration of each part,
The search circuit 1 consists of a power supply battery 8 and a variable resistor 9 connected in series on the positive side, the positive and negative sides of which are connected to terminals 10 and 11 of the switching section 6, respectively.

The time control section 2 of the treatment circuit 5 is mainly composed of an integrated circuit 12 (NE 555 in the embodiment).

That is, the terminal 13 opposite to the terminal 10 of the switching section 6
The No. 4 and No. 8 terminals are connected to the positive line 14 connected to the same, and the No. 1 terminal and the No. 5 terminal into which the capacitor 16 is inserted are connected to the negative line 15.

In addition, a resistor 17 is connected between the No. 6 terminal and the No. 7 terminal, a capacitor 18 is connected in parallel with this resistor 17 and connected to the negative line 15, and the connection point of the resistor 17 is connected to a reset type control switch. 19, and the other terminal of the switch 19 is connected to the second terminal by inserting a protective resistor 20.

Furthermore, the No. 7 terminal is connected to the variable resistor 22 of the frequency adjustment section 3 by inserting a variable resistor 21 for operating time adjustment into the connection point of the resistor 17, and also connects the variable resistor 21 between the two variable resistors 21 and 22.
When the control switch 19 is closed, the operating time is adjusted in the range of 0.5 to 8 seconds by the time constant determined by the resistor 17, variable resistor 21, and capacitor 18. It is designed to be input to the variable resistor 22 of No. 3.

In addition, the frequency adjustment section 3 is an oscillation circuit almost similar to the conventional one,
By connecting a capacitor 23 between the variable resistor 22 and the negative line 15 and changing its time constant,
The oscillation frequency is adjustable within a range of 0.00 to 0.00, and a neon tube 25 for visual recognition and a protective resistor 26 are connected to the secondary side of the oscillation transformer 24, and the intermediate tap on the secondary side is connected to the positive line 14. It is.

The output adjustment section 4 connects a variable resistor 27 to the positive line 14 and connects it to the connection point between the secondary winding of the oscillation transformer 24 and the resistor 26, and a terminal 28 opposite to the terminal 11 of the switching section 6. A diode 29 is connected between the slider of the variable resistor 27 and the slider of the variable resistor 27, and the voltage appearing between the terminals 13 and 28 is divided and adjusted by the slider.

The switching unit 6 has a known configuration in which terminals 29 and 30 each have a movable contact and are opened and closed at the same time, and both terminals are connected to output terminals 31 and 32 by inserting an ammeter M into one of them. has an electrode rod 7 for passing current through the skin,
7' are connected to each other.

Since the present invention has such a configuration, the terminals 29 and 30 of the switching unit 6 are connected to the search system circuit 1 side as shown in the second diagram,
One electrode rod 7 is brought into contact with an arbitrary part of the skin, and the other electrode rod 7' is applied to the skin to apply a direct current to the human body to form a search circuit and search for acupuncture points.

In this way, the position where the pointer of the ammeter M swings maximum can be confirmed as the acupuncture point, and since the resistance value of the acupuncture point can be determined from the displayed current and the set voltage of the variable resistor 9, the therapeutic low value corresponding to this can be determined. The output adjustment section 4 is adjusted so that the frequency current is supplied.

Next, the switching section 6 is connected to the terminals 13 and 28 on the therapeutic circuit 5 side while the electrode rod 7' is kept in fixed contact with the acupuncture point, and the control switch 19 is pressed to close it.

This causes the integrated circuit 12 to operate, and the output of the operating time determined by the capacitor 18, resistor 17, and variable resistor 21 is input to the variable resistor 22 of the oscillation circuit.

Note that the control switch 19 is automatically opened and reset, and the above operation is repeated by pressing this switch.

In this way, the oscillation frequency is adjusted by the variable resistor 22 and capacitor 23 of the oscillation circuit, and the output generated from the oscillation transformer 24 passes through the switching section 6 and is accurately energized to the acupuncture point by the electrode rod 7.7'.

As mentioned above, the present invention detects acupoints using a detection electrode, determines the conduction state of the acupuncture points before applying a low-frequency current for treatment, and fixes the electrode in contact with the acupuncture points. Since the search circuit is switched to the treatment circuit without changing the position of the detection acupuncture point in the slightest,
There is an effect that the output adjustment section can be adjusted to supply the optimum current for treatment without causing excessive current or insufficient current.

In addition, since the current application time can be controlled to a short time and the current stimulation can be applied repeatedly, it is possible to precisely and reliably treat each symptom and its severity.
