2. Description of the Related Art Conventionally, a biostimulator of this type has a main body and an adhesive pad, and a flat plate-shaped output electrode to which an electric pulse is supplied from a pulse generating circuit provided in the main body is arranged on the bottom surface of the main body. Then, a flexible adhesive pad having conductivity is attached and held to the output electrode by its adhesive force.

In the above-mentioned device, when the biostimulator is attached and held to the living body by the adhesive force of the adhesive pad and the pulse generating circuit is operated, the electric pulse from this pulse generating circuit is transmitted through the output electrode and the adhesive pad. It is applied to a living body and can be used for treatment such as loosening the stiff shoulder. As described above, since the biostimulator of this type uses the adhesive pad, it is not necessary to hold the main body by hand during use. After use, the main body is held and the adhesive pad is removed from the living body together with the main body to remove the biostimulator from the living body. In addition,
If sweat or dust adheres to the surface of the adhesive pad due to repeated use and the adhesive strength decreases, remove the adhesive pad from the output electrode and replace it with a new adhesive pad if necessary.

[0004]

In the biostimulator having the above-mentioned structure, when the main body is attached to the living body and used, and then the main body is held and the adhesive pad is peeled off from the living body together with the main body, the adhesive pad is removed from the output electrode. It sometimes peeled off and remained on the living body side. Therefore, there is a problem that the adhesive pad remaining on the living body side has to be peeled off again, and the removing operation after use is troublesome.

It is an object of the present invention to solve the above problems and to obtain a biostimulator having good usability by improving the adhesion holding force between the adhesive pad and the output substrate.

[0006]

In order to achieve the above object, the present invention provides an output substrate having an output electrode on the bottom surface to which an electric pulse from a pulse generating circuit is supplied, and an output electrode of the output substrate. A flexible adhesive pad that is detachably attached and has conductivity and applies an electric pulse to a living body through the electrically conductive adhesive, and an adhesive surface of the output substrate with the adhesive pad is an uneven surface. It is what

[0007]

In the biostimulator of the present invention, since the sticking surface of the output substrate having the output electrode arranged on the bottom surface with the adhesive pad is made uneven, the output substrate and the adhesive pad are more The attachment area becomes large. Therefore, the adhesion holding force between the output substrate and the adhesive pad is improved.

[0008]

An embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a biostimulator main body (hereinafter simply referred to as a main body) as an output base, which is composed of an upper case 2 and a lower case 3 made of synthetic resin, and a side surface thereof holds a battery (not shown) as a power source. The battery holder 4 is detachably provided. The main body 1 has a built-in circuit section that is electrically connected to the battery and that includes a pulse generation circuit that generates a low-frequency electric pulse and a control circuit thereof.

On the upper surface of the main body 1, there is provided a first switch 5 for turning on the output of the electric pulse and increasing the output voltage of the electric pulse. Reference numeral 6 is a second switch for reducing the output voltage of the electric pulse and turning off the output of the electric pulse. Further, 7 is a mode switch which slides on the main body and changes the output form of the electric pulse. There are four types of output form of electric pulse: tataki, fir, shee, and course. These are different in the output interval and output time of the electric pulse, and the stimuli applied to the living body are different. These output forms are the upper surface of the main body 1 (the surface opposite to the sticking surface to the living body).
It is displayed by the display unit 8 formed on the.

A pair of positive and negative output electrodes 9 and 10 electrically connected to the circuit portion are provided on the lower surface 1a of the main body (adhering side to the living body). The output electrode 9 is the lower case 3
A metal plate 11 fixed to, for example, an adhesive and electrically connected to the circuit part, and a silicone-based conductive paint layer 12 printed on the metal plate 11 to prevent oxidation of the metal plate 11. It consists of The surface of the metal plate 11 on which the conductive coating layer 12 is printed is an uneven surface on which minute unevenness is formed as shown in FIG. Then, as shown in FIG. 1, the conductive paint layer 12 has a surface on the side of the metal plate 11 formed in a shape that matches the uneven surface of the metal plate 11, and a surface on the side opposite to the metal plate 11 is a flat surface. A large number of cylindrical protrusions 12b having an outer peripheral surface that is a convex surface are formed on the surface, and this surface is printed so as to be an uneven surface 12a as a whole. The protrusions 12b are formed to have a diameter of 1 mm and a height of about 0.1 mm, and the distance between them is 1 mm.
It is arranged so that it is about a millimeter. The outermost surface of the uneven surface 12a is formed to be substantially flush with the lower surface 1a of the main body 1. Lower surface 1a of the body and output electrodes 9, 10
The sticking surface A is formed by and. The output electrode 10
Is also configured similarly to the output electrode 9. And the main body 1
An annular wall 1b is integrally formed on the periphery of the attachment surface A.

The sticking surface A has an uneven surface 1 of the conductive coating layer 12.
An adhesive pad 13 is attached to the lower surface 2a and the lower surface 1a of the main body by its adhesive force. The adhesive pad 13 is attached to a living body by its adhesive force to hold the main body 1 in the living body, and is made of a water-containing gel substance that is electrically conductive, deformable, flexible, and has an adhesive force. A pad portion 14 that is attached to the electrode 9 and the lower surface 1a of the main body by its adhesive force, and a pad portion 1 that is attached to the output electrode 10 and the lower surface of the main body 1a of the same substance by the adhesive force.
5 and each pad portion 1 embedded in each pad portion 14 and 15
It comprises a mesh-like core material 16 made of a non-woven fabric that reinforces and connects 4 and 15. One end face of the pad portion 14 is an output electrode side attaching face 14a attached to the output electrode 9, and the other end face is attached to the living body side attaching face 1
4b, and in the natural state of the pad portion 14, the output electrode side attaching surface 14a and the living body side attaching surface 14b have substantially the same area. The pad portion 15 has the same structure as the pad portion 14.

In order to attach the adhesive pad 13 to the main body 1, the sticking surfaces of the pad portions 14 and 15 on the output electrode side are positioned over the output electrodes 9 and 10 and the lower surface 1a of the main body, and in that state, the pad portions 14 and 15 are attached. Is pressed to the main body 1 side, the pad portions 14 and 15 are made of a water-containing gel material and have flexibility, so that the output electrode side attachment surface is deformed into a shape matching the uneven surface 12a of the conductive coating layer 12 It is attached to the entire surface 12a. Therefore, the sticking surface A and the adhesive pad 13
The area of attachment between and is larger than the area of attachment between the adhesive pad 13 and the living body. Further, a part of the output electrode side attachment surface of the pad portions 14 and 15 is attached to the lower surface 1a of the main body. As described above, the biostimulator is composed of the main body 1 and the adhesive pad 13.

The operation will be described based on the above configuration.
For example, the pad portions 14 and 1 are provided on a treatment site such as a stiff shoulder of a human body.
The body side attachment surface of 5 is attached, and the main body 1 is held at the treatment site. Then, the mode switch 7 is operated to select the output form of the electric pulse, and the first switch 5 is operated to turn on the output of the electric pulse. To increase the strength of the electric pulse, the first switch 5 is further operated. Then, the electric pulse from the pulse generating circuit is output to the output electrode 9,
A low frequency is applied to the treatment site from the pad portions 14 and 15 of the adhesive pad 13 via 10, and the treatment site is stimulated and treated.

After use, by holding the main body 1 and peeling the sticking surface of the pads 14 and 15 on the living body side from the treatment area,
The body 1 can be removed from the treatment area. According to the biostimulation apparatus of the present embodiment, the sticking surfaces of the adhesive pad 13 and the output electrodes 9, 10 are convex and concave so that the sticking surface A is more than necessary. The adhesion area of these is increased without increasing the size. For this reason,
It is possible to increase the attachment holding force between the attachment surface A and the adhesive pad 13 without making the main body 1 larger than necessary.
Therefore, when removing the main body 1 from the treatment area while holding the main body 1, the adhesive pad 13 does not separate from the treatment area and peels off from the main body 1, and the adhesive pad 13 remains at the treatment area and only the main body 1 is removed. It is possible to prevent this from happening, and improve the operability when removing the main body 1 from the treatment site after use. The adhesive force between the pressure-sensitive adhesive pad and the living body depends on the state of the living body at the time of use due to the presence or absence of sweat, but by forming the uneven surface 12a to the above degree, the living body stimulating device can be used regardless of the state of the living body. It has been confirmed that the adhesive pad 13 does not remain at the treatment site when it is removed from.

Further, in the biostimulator of the present embodiment, in the sticking surface A, the uneven surface 12a is formed on the conductive paint layer 12 of the output electrodes 9, 10 instead of the lower surface 1a of the main body, and an adhesive pad is formed at a portion where a current flows. Since the area of attachment with 13 is increased, the electrical contact resistance between the conductive paint layer 12 and the pad portions 14, 15 is reduced, and a current easily flows through them, so that the pad portions 14, 15 reach the living body. The therapeutic effect of can be improved.

Although the conductive paint layer 12 has an uneven surface in the above embodiment, the lower surface 1a of the main body forming a part of the adhesive surface A has an uneven surface, and the adhesive surface A and the adhesive pad 13 are used. It is also possible to improve the sticking and holding power with. Further, in the above-described embodiment, the case where the output base body is used as the main body has been described, but the same effect can be obtained even when the so-called conductor is used as the output base body via the cord from the main body as conventionally used. Further, the sticking surface 12
The shape and number of the convex surfaces of a are not limited to those in the above-mentioned embodiment, and the sticking area between the sticking surface and the sticky pad is made larger than that of the flat plate so that the sticking holding power of them can be increased. Anything that makes it bigger will do.

[0017]

As described above, according to the biostimulation apparatus of the present invention, the adhesive force between the adhesive pad and the adhesive surface can be increased without making the output substrate larger than necessary. Therefore, it is possible to prevent the adhesive pad from remaining on the living body when removing the portion to be attached to the living body after use, and it is possible to improve usability.
