Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a compact electric pulse therapy device used for treating pine surges, etc., and in particular, it is a compact and cordless device with an integrated conductor. This is related to the mounting structure.

[Prior Art] Conventionally, electric therapy devices that perform pine surge treatment using low-frequency voltage have a main body that contains electronic equipment that generates low-frequency voltage, and an integrated conductor with positive and negative electrodes that is attached to the treatment area of the human body. A low-frequency voltage generator is housed inside the main body, and a power switch, output adjustment knob, etc. are provided on the outside. In this case, the cord connected to apply a low-frequency voltage to the conductor may get tangled each time the treatment section of the conductor is changed or moved, which gives no flexibility and is very troublesome.

Therefore, as a cordless type of low frequency treatment device that has been developed, there is one described in Japanese Utility Model Publication No. 58-26664. In this structure, the conductor that is pressed against the treatment area is integrated with the main body containing the low-frequency generator and the case, but a hydrous treatment pad is used for the conductor, and the electrode holding member is attached to the case. It was something that was kept. Then, a stimulation current with a low frequency therapeutic electrical waveform is supplied to the treatment area by a hydrous ms pad pressed against the treatment area, thereby performing pine surge treatment.

[Problems to be Solved by the Invention] However, in the above-mentioned electrotherapy device, the conductor is integrated with the main body that contains a low frequency generator, etc., but when it is attached to the treatment area of the human body, it loses its own weight. This was a problem as it sometimes fell off. However, if the device was made smaller so that it would not be affected by its own weight, it would have the disadvantage of worsening the therapeutic effect. In addition, the cases of these electrotherapy devices were made of hard plastic or metal, and the joint surface to the #I treatment area was a planar structure, so it was difficult to attach the electrotherapy device to the uneven skin surface. Since it was not possible to make a physical contact with the electrode, many floating points were created, which reduced the effective therapeutic contact area that the electrode had on the treatment area and caused discomfort.

In view of the above-mentioned circumstances, the purpose of this invention is to provide a compact electrotherapy device that integrates the conductor into the main body to make it cordless, compact, and brings it into close contact with the treatment area to increase the therapeutic effect. be.

[Means for Solving the Problems] The small electric #1m device of the present invention connects positive and negative electrodes to a wiring board on which electronic equipment is mounted, and each electrode has a flexible electrode pad and a conductive A conductor consisting of an adhesive pad is connected to the conductor, and both conductors are spaced apart and attached to a main body case made of a flexible material.

[Function] According to the present invention, the conductor, which is spaced apart and attached to the main body case made of a flexible material, is composed of a flexible electrode pad and a conductive adhesive pad, so that it can be used anywhere on the human body. Even if the treatment area has a curved surface, the guide can be adhered closely following the curved surface, and comfortable and effective pine surgery treatment can be performed without causing excess or deficiency in the therapeutically effective contact area. Additionally, since it is attached to the skin of the treatment area using a conductive adhesive pad, it will not fall off due to its own weight.

[Example J Embodiments of the present invention will be described below based on the drawings.

FIG. 1 shows the structure of a small flexible electrotherapy device according to an embodiment of the present invention.

According to this figure, the small electric pulse therapy device has a structure including a wiring board 1, a conductor 2, a main body case 3, and the like. The wiring board 1 includes an IC chip 11 that generates a low frequency voltage of 100 to 200 cm, and an output adjustment knob 12 that adjusts the output of the voltage and also serves as a power switch.

It consists of adhesive pads 23 and 24. A pair of electrode pads 21 and 22 included in both conductors 2 are integrally molded, for example, by two-color molding, with an insulating rubber portion 25 interposed therebetween. Conductive adhesive pad 23
．． 24 are electrode pads 21 and 22, respectively, except for the thickness.
The electrode pad 21. is formed to have approximately the same dimensions as the electrode pad 21. in order to be replaceable in case of dirt or deterioration. ．． 22
is covered with. When replacing such electrode pads 21.22, the insulating rubber portion 25 is attached to the circular electrode pads 21.22.
For this purpose, the electrode pads 21, 22 are
The insulating rubber part 25 is preferably formed in a color different from that of the skin, and has the function of preventing the reinforcing plate 6, which will be described later, from coming into direct contact with the skin during use.

The main body case 3 is made of a soft and flexible material such as rubber, soft synthetic resin, or thermoplastic elastomer,
Two parallel grooves 31 extending in the width direction are provided on the upper surface side. This groove 31 is for easily bending both side parts with respect to the central part.
1. Both sides have a size corresponding to the conductor 2. 0. In the center of the main body case 3, there is a cutout hole 32 for exposing the operation switch on the top surface, and an output adjustment knob on the side surface. A notch hole 33 is provided for the purpose. Further, an inner case 5 made of a hard plastic case is arranged above the wiring board l, and a reinforcing plate 6 is arranged below. Like the main body case 3, the inner case 5 is provided with a notch hole 51 for an output lead and a power supply lead, a notch hole 55 for an operation switch, and a notch hole 53 for an output adjustment knob. The wiring board 1 is housed in the inner case 5 with the sides to which the IC chip 11 and various operation switches 13 are attached facing each other, and its upper surface is covered with a reinforcing plate 6. At this time, the operation switch 13 is exposed from the cutout hole 52 of the inner case 5, and the output leads 14, 15 and the power supply lead 18 are pulled out from the cutout hole 51. Wiring board 1 and reinforcing plate 6
The inner case 5 to which the inner case 5 is attached is stored in the center of the main case 3, and the power source batteries 4 are stored in both sides of the main case 3. In this way, in the groove 31 of the main body case 3,
Only flexible members such as the output leads 14 and 15 and the power supply lead 18 correspond, and flexible conductors 2 correspond to both sides of the main body case 3 except for the power supply battery 4.

Next, the case of assembling the above-mentioned fixtures will be explained. First, remove the inner case 5 so as to cover the wiring board l.
The positive and negative electrodes 16 and 17 are inserted through the predetermined notch holes 51.
Output leads 14, 15 and power supply leads 18 connected to
The inner case 5 in this state is held by the reinforcing plate 6.

Furthermore, it is housed and attached to the main body case 3. Power lead 1
8 is connected to the power battery 4 placed in an insulator case,
The power source batteries are located inside both sides of the main body case 3. The positive and negative electrodes 16 and 17 each have an insulating rubber portion 25.
It is connected to either one of the electrode pads 21 and 22 arranged in a separated manner on the left and right. Conductive adhesive pads 23, 24 are attached to each electrode pad 21, 22, and the electrode pads 21, 22 are attached to the main body case 3. During this installation, the electrode pad 21.
The insulating rubber part 25 integrated with the main body case 22 is located on the lower surface of the inner case 5 attached to the main body case 3.

A small electric 1hfl consisting of the above! *M means that when pressed against the treatment area of the human body, the conductor 2 flexibly follows the curved surface of the skin together with the flexible main body case 3 and bends, as shown in FIGS. 2 and 3, and the conductive adhesive pad It will be attached on 23.24. Since the groove 31 is carved in the longitudinal direction of the device, the flexibility is further improved (see Fig. 2), and since both the conductor 2 and the main body case 3 are flexible, it can be bent freely even in a distorted manner. (See FIG. 3). Therefore, since the conductive adhesive pads 23 and 24 can be brought into close contact with any treatment area, the effective treatment contact area can be utilized to the maximum extent possible.

Next, select the treatment mode with the operation switch 13 such as "kneading", "r-pat", "grasp" etc. exposed from the notch hole 32 formed on the top surface of the main body case 3, and then turn on the power switch and output adjustment knob. 12, the output is adjusted to provide optimal treatment.

Note that when not in use, a protective case 7 is used that fits under the small electrotherapy device and covers the conductive adhesive pads 23 and 24. Since this protective case 7 is attached to the conductive adhesive pads 23 and 24 of the conductor 2, there is no need to provide a special attachment member.

In addition, it goes without saying that when installing the electrotherapy device in the treatment section, it is possible to optionally incorporate a slow start function to prevent time-shock, an LED indicator for output confirmation, and the like.

Furthermore, as another embodiment of the present invention, the main body case 3
The power battery 4 interposed between the electrode pads 21 and 22 may be built into the inner case 5. In this case, since no hard power battery is interposed between the main body case 3 and the conductor 2, It becomes possible to increase the degree of freedom of deformation.

Furthermore, if a rib or the like is formed on the main body case 3 for attaching the wiring board 1, etc., the inner case 5 can be omitted, and the assembly can be made simple and easy.

- Furthermore, as another embodiment, the electrode pads 21 and 22 integrated with the insulating rubber part may be separated, or the conductive adhesive pads 23 and 24 may be opened only at the part to which the conductive adhesive pads are attached. The structure may be such that the body case 3 is covered with a separate flexible case member, and the body case does not need to be flexible as long as it has flexibility.

Although the above is a low frequency treatment device for treatment using low frequency, the present invention is not limited thereto and can also be applied to a high frequency treatment device.

[Effects of the Invention] As a result of the above, the small electric pulse therapy device of the present invention has a flexible main body, so it can be easily and easily attached to the treatment area even on the undulating curved surface of the human body, and the treatment can be performed easily. Since the effective contact area is increased, the therapeutic effect is increased. Even if a large-area conductive adhesive pad is used, a good therapeutic feel can be obtained due to its adhesiveness. Furthermore, it will not fall off due to its own weight, and safety in use and simple configuration can ensure easy operability.
