Description

[Detailed description of the invention] The present invention relates to a low-frequency treatment device that searches for acupuncture points, so-called acupoints, on 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 apply the optimal low-frequency current for treatment, it is necessary to confirm the continuity of the acupuncture point.
According to conventionally used acupuncture points detectors and low-frequency treatment devices, both are operated separately, and the latter low-frequency current is passed through the acupoints detected by the former, so the detected acupuncture points and the current energizing point are different from each other. In addition to being easily misaligned, the prescribed low-frequency current is passed without checking the continuity of the acupuncture points, which often leads to excessive or insufficient current, and the current may not be optimal for achieving therapeutic effects. There were many.

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 treatment device in which the pulse width of the oscillation waveform can be freely changed to suit the symptoms and their severity, and the number of electrical stimulations can be repeated as desired.

The drawing shows one embodiment of the present invention, which will be explained below.As shown in FIG. A treatment circuit 5 consisting of a waveform pulse width conversion section 2, an oscillation section 3, and an output adjustment section 4, a switching section 6 for switching between the search circuit 1 and the treatment circuit 5, and an output side of the switching section 6. It consists of electrode rods 7, 7' which are connected to each other and apply a low frequency current to the skin.

FIG. 2 shows a specific example of the circuit configuration of each part, and the search system circuit 1 consists of a power supply battery 8 and a variable resistor 9 connected to the positive side.
The positive and negative sides thereof are connected to terminal 1 of the switching unit 6, respectively.
It is connected to 0jl.

Further, in the pulse width conversion section 2 of the treatment system circuit 5, input terminals S having movable contacts are connected to capacitors C1, C2 and C2, respectively.
The main body is a pulse width switch 13 which is connected to each terminal Sl, S2, etc. inserted and connected to the negative line 12, and the input terminal S is connected to the control switch 14. The control switch 14 is of a return type in which a resistor 16 is inserted and the contact 18 connected to the positive line 17 and the contact 15 are always closed.

The oscillation unit 3 is composed of an oscillation circuit similar to the conventional one,
One end of the primary coil of the oscillation transformer 19 is connected to the negative line 12, and the other end of the coil is connected to the control switch 1.
4, and a neon tube 21 for visual recognition is connected to the secondary side thereof. A resistor 22 is connected.

Therefore, when the contacts 15.18 of the control switch 14 are closed, the current from the positive line 17 flows through the capacitor C1, which is connected to the input terminal S of the pulse width switch.
C2...... is charged, but control switch 1
4 to open contact 15j8 and close contact 15.20, the charge voltage of the capacitors C1, C2, . . . is applied to the oscillation transformer 19, and a pulse wave is oscillated.

The width of this pulse waveform is determined within the range of 0°5 to 1.5 ms by the values of the capacitors C1, C2, etc., and is converted by switching the pulse width switch 13 to each capacitor. do.

The output adjustment section 4 connects a variable resistor 24 to a positive line 17 connected to a terminal 23 opposite to the terminal 10 of the switching section 6.
is inserted and connected to the connection point between the secondary side of the oscillation transformer 19 and the resistor 22, and the terminal 2 facing the terminal 11 of the switching section 6 is connected to the connection point between the secondary side of the oscillation transformer 19 and the resistor 22.
A diode 26 is connected between the variable resistor 5 and the slider of the variable resistor 24, and the slider divides and adjusts the voltage appearing between the terminals 23 and 25.

Furthermore, the switching unit 6 has a known configuration in which the terminals 27 and 28 each have a movable contact and are opened and closed at the same time, and both terminals have an ammeter M inserted into one of them and an output terminal 29.
．． 30, and each output terminal is connected to an electrode rod 7, 7' for contacting the skin and passing an electric current through it.

As shown in FIG. 2, the therapeutic device of the present invention configured in this manner connects the terminals 27 and 28 of the switching unit 6 to the terminals 10 and 10 on the search system side.
11, one electrode rod 7' is brought into contact with any part of the skin, and the other electrode rod 7 is applied to the skin, and a direct current is passed through 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 to its maximum is detected as the pressure point, but at the same time the displayed current and the variable resistance 9
Since the resistance value of the acupuncture point is determined based on the set voltage, the output adjustment unit 4 is adjusted so that a therapeutic low frequency current commensurate with this is supplied.

Next, while keeping the electrode rod 7 fixed in contact with the acupuncture point, the switching section 6 is switched to the terminals 23 and 25 on the therapeutic circuit 5 side, and the control switch 14 is pressed.

As a result, the charge voltage of the capacitor selected by the pulse width switch 13 is applied to the oscillation transformer 19, and a low frequency current due to the oscillated pulse wave of a predetermined width is applied to the electrode rod 7.
Electricity is accurately applied to the acupuncture points detected through the sensor.

Note that the control switch 14 is automatically reset, and by pressing this switch, the above operation is repeated.

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 system circuit is switched to the treatment system circuit without causing any deviation in the position of the acupuncture points, the output adjustment section can be adjusted to obtain the optimal current for treatment without causing excessive or insufficient current. It has the effect of being able to conduct electricity.

In addition, the pulse width of the therapeutic current can be adjusted according to the symptoms and their severity, and furthermore, this electrical stimulation can be repeated at will, increasing the stimulation effect of the acupuncture points and providing detailed treatment. There are effects that can be achieved.
