Description

[Detailed Description of the Invention] A. Purpose of the Invention (1) Industrial Application Field The present invention aims to treat stiff shoulders by bringing a low frequency treatment device, particularly a local conductor, into contact with acupuncture points of the human body and applying a low frequency current to the acupuncture points of the human body.
This invention relates to a low frequency therapy device for alleviating neuralgia and muscle pain.

(2) Conventional Technology Conventionally, with such low-frequency treatment devices, the user searches for his own acupuncture points and performs treatment by referring to a map of the acupuncture points of the human body.

(3) Problems to be solved by the invention Searching for acupuncture points as in the past is complicated, and moreover, it is difficult to detect acupuncture points accurately.

Therefore, in order to solve the above problem, for example, when the local guide of the treatment device detects an acupuncture point, the notification sound is made louder, and when the local guide is pressed against the acupuncture point, a low frequency current is caused to flow through the acupuncture point. A method has already been proposed (see Japanese Patent Application Laid-Open No. 54-93892), but with this method, even after the acupuncture point has been detected, as long as low-frequency current is applied to the acupuncture point and treatment is continued, it will not work. The relatively loud notification sound continues throughout the treatment, which is annoying to the ears during treatment, and there is another problem in that it wastes electricity.

The present invention has been proposed in view of the above, and is capable of solving the above-mentioned problems of the conventional device, and also makes it easier to hear the notification sound of the acupuncture point detection audio notification device.
The purpose is to provide a low frequency treatment device.

B. Structure of the Invention (1) Means for Solving the Problems In order to achieve the above object, according to the present invention, a local conductor formed in a rod shape of a conductive metal has a limited range in its longitudinal direction. is held by a gripping rod electrically insulated from the local conductor, and between the gripping rod and the local conductor,
A spring is interposed to bias the tip of the local conductor in a direction protruding from the tip of the gripping rod, and the base end of the gripping rod is always in contact with the base end of the local conductor. A first contact point, a second contact point capable of contacting the proximal end portion of the local conductor by moving the local conductor backward against the spring force of the spring, and a high impedance audio alarm; The first contact is connected to a low frequency power source via the audio alarm, and the second
A contact is connected to a low frequency power source in parallel to the audio alarm and the first contact.

(2) Effect With the conductor connected to the low-frequency power source applied to the therapist, when the local conductor is applied relatively lightly to the affected area of the patient using the above-mentioned gripping rod and moved appropriately, the local conductor is When it comes into contact with an acupuncture point, a relatively large low-frequency current can be passed through the first contact point to the alarm side, and a relatively loud alarm sound can be generated from the alarm, so at that time, the area that the local guide touches It is possible to easily detect if it is an acupuncture point.
Then, by simply pushing the grip rod at the detection site and pushing the local electrode into the grip rod, the local electrode and the second
Since the contacts are electrically connected and the low-frequency current flows bypassing the alarm, a relatively large amount of low-frequency current can be effectively passed through the acupuncture points to provide treatment while suppressing the sound generated by the alarm. It can be carried out.

(3) Embodiment Hereinafter, an embodiment of the present invention will be explained with reference to the drawings. First, in FIG. 1, a portable bag 1 is shown.
A control box 2 is housed inside the control box 2, and a low frequency power source (not shown) is built in the control box 2. A conductor 5 is connected via a cord 4 to a connecting terminal 3 connected to one terminal of this low frequency power source. A cord 7 is connected to a connecting terminal 6 connected to the other terminal of the low frequency power source, and this cord 7 is connected to a local conductor 9 (see FIG. 2) held by a gripping rod 8. . Low frequency treatment is performed by bringing the local guide 9 into contact with an acupuncture point while the guide 5 is held in contact with the human body, such as by grasping it with one hand.

A 100V AC power supply can be connected to the control box 2, and the top surface of the control box 2 includes a power switch 10, an output waveform switching knob 11, an oscillation indicator 12, and an output adjustment knob 1.
3, an output indicator 14, a power light 15, a timer switch 16, etc. are arranged. Also, inside bag 1,
A storage recess 17 is provided for storing the conductor 5, the gripping rod 8, both cords 4 and 7, and the like.

The conductor 5 is wrapped in a water-wet cloth and housed in a synthetic resin cover, and the conductor 5 is placed so that the cloth facing the opening provided in the cover comes into contact with the human body. Electrical contact is made between the body and the human body.

In FIG. 2, the gripping rod 8 includes a main body 18 made of an electrically insulating material such as a synthetic resin and having a cylindrical shape, and a main body 18 that is basically formed in a cylindrical shape with a bottom and made of an electrically insulating material such as a synthetic resin. a cap 19 screwed onto one end of the main body 18; a support member 20 formed essentially in a cylindrical shape made of an electrically insulating material and fitted into the other end of the main body 18; and a support member 20 made of an electrically insulating material such as rubber. and the main body 18 so as to cover the support member 20.
and a cover 21 fitted to the other end. The gripping rod 8 is therefore generally formed of an electrically insulating material and essentially cylindrical.

On the other hand, the local conductor 9 is formed in the shape of a round bar from a conductive metal, and a spherical contact portion 22 is integrally provided at the tip thereof. This local guide 9 is inserted into the grip rod 8 through an insertion hole 23 made in the cap 19. A locking collar 24 is fixed near the tip of the local guide 9 within the gripping rod 8, and this locking collar 24
By contacting the cap 19, the local conductor 9 is prevented from coming off the grip rod 8. Further, an inner flange 25 is integrally provided on the inner surface near one end of the main body 18, and a coil-shaped spring 26 surrounding the local conductor 9 is disposed between the inner flange 25 and the locking flange 24. is interposed. Therefore, the local guide 9 is supported by the gripping rod 8 while being movable in the longitudinal direction within a limited range, and is biased by a spring in the direction in which the tip, that is, the spherical contact portion 22 protrudes from the gripping rod 8. ing.

The local conductor 9 has such a length that its rear end protrudes into the support member 20 when the locking collar 24 is in contact with the cap 19 as shown in FIG. On the other hand, the support member 20 includes a first contact point 27 that is in constant contact with the rear end of the local guide 9, and a first contact point 27 that is in constant contact with the rear end of the local guide 9, and a A second contact 28 with which the rear end contacts is provided.

The first and second contacts 27 and 28 are formed into wire shapes. Moreover, the first contact point 27 is disposed facing a slit 29 provided in the support member 20 along the axial direction, and is bent so as to come into elastic sliding contact with the outer surface of the local conductor 9. Also, the second contact 28
is buried along one diameter line of the support member 20.

A high impedance voltage buzzer 30 is attached to the cover 21 as an audio alarm, and one end of this voltage buzzer 30 is connected to the first contact 27 via a first lead wire 31.
The other end of 0 is connected to a cord 7 attached to the side wall of the cover 21. Further, one end of a second lead wire 32 is connected to the second contact point 28, and the other end of this second lead wire 32 is connected to the cord 7. Therefore, the second contact 28 is connected to the low frequency power source in parallel with the voltage buzzer 30.

Next, the operation of this embodiment will be explained. For low frequency treatment, the cords 4 and 7 are connected to the connection terminals 3 and 6, the power switch 10 is turned on, and the output waveform switching knob 11 and output adjustment knob Knob 1
3 rotated to an appropriate position, grasp the guide 5 with one hand, grasp the gripping rod 8 with the other hand, and bring the contact portion 22 of the local guide 9 into contact with the part of the human body to be treated. In this state, the first contact point 27 is in contact with the local conductor 29, so the conductor 5
A sound is generated from the voltage buzzer 30 in response to the low frequency current being passed between the local conductors 9.

In this state, when the gripping rod 8 is moved along the surface of the human body and the contact portion 22 of the local conductor 9 reaches the position of the acupuncture point, the output sound of the voltage buzzer 30 increases as the amount of current increases. becomes large. This allows the position of the acupuncture point to be detected, and when the gripping rod 8 is pressed toward the human body, the local guide 9 is pushed into the gripping rod 8 against the spring force of the spring 26. Then, the first and second contacts 27 and 28 come into contact with the local conductor 9, and since the voltage buzzer 30 has a high impedance, the low frequency current flows bypassing the voltage buzzer 30. Therefore, no sound is output from the voltage buzzer 30, and it is possible to perform treatment by flowing a relatively large amount of low frequency current to the acupuncture points.

C. Effects of the Invention As described above, according to the present invention, the local conductor formed into a rod shape made of conductive metal is allowed to move within a limited range in the longitudinal direction, and the local conductor It is held by an electrically insulated gripping rod, and a spring is interposed between the gripping rod and the local conductor to bias the tip of the local conductor in the direction of protruding from the tip of the gripping rod. , at the proximal end of the gripping rod,
a first contact that constantly contacts the proximal end of the local conductor; and a second contact that can come into contact with the proximal end of the local conductor when the local conductor moves backward against the spring force of the spring.
a contact and a high impedance audio annunciator, the first contact being connected to a low frequency power source via the audio annunciator, and the second contact being connected in parallel to the audio annunciator and the first contact. The device is connected to a low-frequency power source, so with the conductor connected to the low-frequency power source applied to the therapist, hold the above-mentioned gripping rod and relatively lightly apply the local conductor near the affected area of the therapist and move it as appropriate. When the local conductor comes into contact with an acupuncture point, a relatively large low-frequency current can be passed through the first contact to the alarm, causing the alarm to generate a relatively loud alarm sound, and therefore the local If the area that the guide touches is an acupuncture point, it can be easily detected. Then, by simply pushing the grip rod at the detection site and pushing the local conductor into the grip rod, conduction will occur between the local conductor and the second contact, allowing the low-frequency current to flow bypassing the alarm. , it is possible to effectively perform treatment by flowing a relatively large amount of low-frequency current to the acupuncture points while suppressing the generation of notification sounds from the alarm, and therefore, the notification sound from the alarm becomes harsh during the treatment. You can continue to receive comfortable treatment without having to worry about
Furthermore, compared to conventional devices that continue to emit a notification sound even during treatment, power consumption can be saved. Furthermore, since the above-mentioned alarm and the first and second contacts to be connected in series or parallel to it can be arranged together at the base end of the gripping rod for the local conductor, the connection circuit can be made as short as possible. In addition, the alarm can be brought as close as possible to the user holding the grip bar, making it easier to hear the alarm.
