Description

  The present invention relates to a low-frequency treatment device pad and a low-frequency treatment device.

  When treatment is performed using a low-frequency treatment device, it is common to perform a treatment by attaching a pair of pads to a treatment site. As such a pad, one having a conductive layer inside and a conductive adhesive layer on the surface and having flexibility so that it can be attached to each part of a human body is known.

  In addition, in order to provide various treatment modes, one pad is divided into a plurality of conductive parts. Such a pad will be briefly described with reference to FIG. FIG. 10 is a perspective view of a pad having a plurality of conductive portions.

  In the illustrated pad 200, the conductive portion is divided into three strips by two non-conductive portions 211 and 212. That is, in the pad 200, the conductive part is divided into a first conductive part 201, a second conductive part 202, and a third conductive part 203. These conductive portions are connected to electric wires 301, 302, and 303, respectively, and are configured to be individually energized.

  According to the pad 200 configured as described above, various treatment modes can be provided by appropriately controlling the energization timing and the energization amount of each conductive part.

  However, in general, in the pad having the adhesive layer on the surface, when the dust adheres to the adhesive surface, or the adhesive force decreases due to deterioration over time, the part or shape with a small curvature radius is complicated. When pasted on a part, a part of the pad may be peeled off. FIG. 11 is an external view showing a state in which a part of the pad attached to the treatment site has been peeled off.

  Here, as described above, in the pad 200 in which the conductive portion is divided into a plurality, if a part of the pad 200 is peeled off, only one conductive portion has a reduced contact area with the human body. In particular, as shown in FIG. 10 described above, in the pad 200 in which the conductive portion is divided into a plurality of strips, the area of one conductive portion is narrow in the first place. The rate of decline will increase. 10 and 11, the part indicated by the arrow X indicates the part that has been peeled off.

  Thus, when the contact area to the human body in the conductive portion is reduced, the current is concentrated on a local portion. Therefore, only one conductive part has a higher current concentration ratio than the other conductive parts, and a desired treatment mode cannot be realized. Moreover, since the current concentrates on a local portion, excessive irritating stimulation may occur. In addition, regarding the latter, even if the conductive portion is not of a divided type, there is a problem that may occur in the same manner if the conductive portion has an originally small area.

Note that there are Patent Documents 1 and 2 as documents disclosing related technologies.

  An object of the present invention is to provide a low-frequency treatment device pad and a low-frequency treatment device that can prevent the area of the conductive portion from greatly decreasing even if a part of the pad is peeled off.

  The present invention employs the following means in order to solve the above problems.

That is, the present invention
In the low frequency treatment device pad to be attached to the treatment site,
A conductive portion provided at a position away from the outer peripheral edge of the pad;
An adhesive portion provided in a region surrounding the conductive portion;
It is characterized by providing.

  According to the present invention, since the adhesive part is provided in the region surrounding the conductive part, even if a part of the adhesive part is peeled off, the conductive part is not affected, and the contact area of the conductive part to the human body is increased. It can prevent that it falls.

  Here, if the adhesive part is provided so as to surround the conductive part, even if the adhesive part is provided in a plurality of discontinuous rather than continuous parts, the conductive part is conductive even if a part of the adhesive part is peeled off. It does not affect the department.

  However, even if a part of the adhesive part is peeled off, the adhesive part should continuously surround the conductive part so as not to affect the conductive part more reliably. It is desirable that it is provided.

  In addition, it is preferable that an adhesive portion is provided also in a region that coincides with the conductive portion.

  As a result, the conductive portion can be more reliably attached to a part having a small curvature radius or a part having a complicated shape.

A non-conductive part is provided along the periphery of the conductive part, and a second conductive part electrically separated from the conductive part by the non-conductive part is provided along the outer peripheral edge of the pad. As
The outer peripheral shape of the pad is a shape in which a part of an ellipse is recessed, and the outer peripheral shape of the non-conductive portion is substantially similar to the outer peripheral shape of the pad, and is provided along the conductive portion and the periphery of the conductive portion. The non-conductive portion to be formed may be disposed near the center of the pad.

  In this way, when the second conductive portion is provided along the outer peripheral edge of the pad separately from the conductive portion provided at a position away from the outer peripheral edge of the pad, a part of the second conductive portion is narrowed. Therefore, it is possible to suppress the impedance from increasing.

In addition, the low frequency treatment device of the present invention,
A low frequency treatment device that generates low frequency,
A cord connected to the body of the low frequency treatment device;
A pad attached to the tip of the cord;
In a low frequency treatment device comprising:
The pad
A conductive portion provided at a position away from the outer peripheral edge of the pad;
An adhesive portion provided in a region surrounding the conductive portion;
It is characterized by providing.

  According to the present invention, since the adhesive part is provided in the region surrounding the conductive part, even if a part of the adhesive part is peeled off, the conductive part is not affected, and the contact area of the conductive part to the human body is increased. It can prevent that it falls.

  Here, if the adhesive part is provided so as to surround the conductive part, even if the adhesive part is provided in a plurality of discontinuous rather than continuous parts, the conductive part is conductive even if a part of the adhesive part is peeled off. It does not affect the department.

  However, even if a part of the adhesive part is peeled off, the adhesive part should continuously surround the conductive part so as not to affect the conductive part more reliably. It is desirable that it is provided.

  In addition, said each structure can be employ | adopted combining as much as possible.

  As described above, according to the present invention, it is possible to prevent the area of the conductive portion from being greatly reduced even if a part of the pad is peeled off.

  The best mode for carrying out the present invention will be exemplarily described in detail below with reference to the drawings. However, the dimensions, materials, shapes, relative arrangements, and the like of the components described in this embodiment are not intended to limit the scope of the present invention only to those unless otherwise specified. .

The CPU 23 is configured to be supplied with electricity from a power supply unit 24 provided in the low frequency treatment device body 20.
Then, based on the signal sent from the operation unit 21, the CPU 23 causes the display unit 22 to display setting contents, treatment time, and the like, and causes the waveform shaping / output unit 25 to generate a low frequency pulse. The low frequency pulse output from the waveform shaping / output unit 25 is applied to the treatment site of the human body M via the pad 10.

<Pad>
In particular, the pad 10 according to the first embodiment of the present invention will be described in detail with reference to FIGS. 3 and 4. FIG. 3 is a plan view of the low-frequency treatment device pad according to the first embodiment of the present invention (viewed from the side to be attached to the treatment site). FIG. 4 is a schematic cross-sectional view of the pad for a low frequency treatment device according to the first embodiment of the present invention.

  The pad 10 according to the present embodiment has flexibility so that it can be attached to each desired part of the human body. The pad 10 includes a conductive layer 11 provided inside, a conductive adhesive layer 12 provided on the surface side, an electrode hook 13 electrically connected to the conductive layer 11, and an electrode hook in the conductive layer 11. And a protective layer 14 that covers the back surface other than the portion where 13 is provided. In addition, the adhesion layer 12 is comprised with the gel material. Further, the pad 10 can be easily attached to and detached from the cord 30 by fitting or removing the snap 32 provided at the tip of the cord 30 to the electrode hook 13.

  Next, the arrangement of the conductive layer 11 will be described in detail with particular reference to FIG. In the present embodiment, as shown in FIG. 3, the conductive layer 11 is provided at a position away from the outer peripheral edge of the pad 10. A region where the conductive layer 11 is provided is referred to as a conductive portion P10. Further, the adhesive layer 12 is provided over the entire surface except for a part (Y portion in the figure) including the outer peripheral edge of the pad 10. In the new pad 10, a protective film for protecting the surface of the adhesive layer 12 is provided. When the pad 10 is used for the first time, the adhesive layer 12 is used as described above in order to facilitate the peeling of the protective film. A portion (Y portion in the figure) where no is provided is provided.

  Thus, the adhesive layer 12 is provided in a region (referred to as the first adhesive portion Q10) that coincides with the conductive portion P10 and a region (referred to as the second adhesive portion Q20) surrounding the conductive portion P10. In this embodiment, as is apparent from the drawing, the second adhesive portion Q20 is provided so as to continuously surround the conductive portion P10.

<Excellent points of this embodiment>
As described above, according to the pad 10 according to the present embodiment, since the adhesive portion (second adhesive portion Q20) is provided in the region surrounding the conductive portion P10, a part of the second adhesive portion Q20 is peeled off. However, the conductive portion P10 is not affected.

  FIG. 5 is a back view showing a state where a part of the low-frequency treatment device pad according to the embodiment of the present invention is peeled off (viewed from the surface side to which the cord is connected). As is apparent from this figure, even if a part of the second adhesive portion Q20 is peeled off, the conductive portion P10 is not affected. In the figure, the part indicated by the arrow X is the part that has been peeled off. Therefore, it can prevent that the contact area to the human body in the electroconductive part P10 falls by peeling of a part of 2nd adhesion part Q20.

  Here, even if the first adhesive portion Q10 is not provided in a region that coincides with the conductive portion P10, the contact area of the conductive portion P10 with the human body due to part of the second adhesive portion Q20 being peeled off. Will not be affected. However, in the present embodiment, the region corresponding to the conductive portion P10 is also applied to the region corresponding to the conductive portion P10 so that the conductive portion P10 can be more reliably attached even to a portion having a small radius of curvature or a portion having a complicated shape. One adhesive portion Q10 is provided.

  Here, as long as the second adhesive part Q20 is provided so as to surround the periphery of the conductive part P10, the second adhesive part Q20 is not continuous but is provided at a plurality of discontinuous locations. Even if a part is peeled off, the conductive part P10 is not affected. However, even in the case where a part of the second adhesive part Q20 is peeled off, in order to prevent the conductive part P10 from being affected more reliably, in the present embodiment, the second adhesive part Q20 is It is provided so as to continuously surround the periphery of the conductive portion P10.

(Example 2)
FIG. 6 shows a second embodiment of the present invention. In the first embodiment, the case where the conductive portion is configured by a single electrode that is not divided is shown. However, in the present embodiment, the configuration when the conductive portion is divided is shown. Since other configurations and operations are the same as those in the first embodiment, the same components are denoted by the same reference numerals and description thereof is omitted.

  FIG. 6 is a plan view of the low frequency treatment device pad according to the second embodiment of the present invention (viewed from the side to be attached to the treatment site). In the said Example 1, the case where the monopolar electroconductive part P10 was provided in the area | region corresponding to the 1st adhesion part Q10 was demonstrated. In this embodiment, a configuration in which the conductive portion P10 is divided is adopted. That is, in this embodiment, in the area indicated by S in FIG. 6A (corresponding to the area where the first adhesive portion Q10 is provided), for example, as shown in FIGS. 6B, 6C, and 6D. As described above, a plurality of conductive portions P10 are provided as appropriate. A non-conductive portion R10 is provided between the individual conductive portions P10, and the individual conductive portions P10 are insulated.

  As described above, in this embodiment, since one pad 10 has a plurality of conductive portions P10, each conductive portion P10 can be individually energized. By appropriately controlling the energization amount, it is possible to have diversity in the treatment mode.

Also in the present embodiment, although the conductive portion P10 is divided into a plurality of parts, the adhesive portion (second adhesive portion Q20) is provided in the region surrounding the conductive portion P10, although it is different from the first embodiment. Is the same as in the case of the first embodiment, and the same effect as in the case of the first embodiment can be obtained. In the present embodiment, even if a part of the second adhesive portion Q20 is peeled off, the plurality of conductive portions P10 are not affected, so that a desired treatment mode can be stably maintained.

(Example 3)
FIG. 7 shows a third embodiment of the present invention. In the first embodiment, the configuration in which the conductive portion is not provided in the region where the second adhesive portion Q20 is provided is shown, but in the present embodiment, the region where the second adhesive portion Q20 is provided is also provided. The structure which provides an electroconductive part is shown. Since other configurations and operations are the same as those in the first embodiment, the same components are denoted by the same reference numerals and description thereof is omitted.

  FIG. 7 is a plan view of a low-frequency therapeutic device pad according to Example 3 of the present invention (viewed from the side to be attached to the treatment site). In the present embodiment, a nonconductive portion R10 is provided along the periphery of the conductive portion P10, and a conductive portion (hereinafter referred to as a second conductive portion P20 for convenience of description) is further provided outside the nonconductive portion R10. ). That is, in the present embodiment, the conductive portion is provided also in the region where the second adhesive portion Q20 is provided, that is, in a position not separated from the outer peripheral edge of the pad 10a.

Also in the present embodiment, the conductive portion P1 provided at a position away from the outer peripheral edge of the pad 10a.
Regarding 0, since the second adhesive portion Q20 is provided in the region surrounding the conductive portion P10, the same effect as in the case of the first embodiment can be obtained.

  Here, in the case of a present Example, when a part of 2nd adhesion part Q20 peels, the contact area to the human body in the 2nd electroconductive part P20 will fall. However, in this embodiment, the second conductive portion P20 is provided along the outer peripheral edge of the pad 10a and has a large area. Therefore, the rate of decrease in the contact area with the human body is only a little peeled off. Is small. Therefore, even if a part is peeled off, the current will not concentrate on the local part, and the desired treatment mode may not be realized or excessive stimulation may occur. There is no.

  Thus, if the area of the conductive portion is large and a part of the conductive portion is peeled off, if the rate of decrease in the contact area with the human body is small, the conductive portion is separately provided at a position not separated from the outer peripheral edge of the pad 10a. It does not matter if it is provided.

  In the present embodiment, as in the case of the second embodiment, the conductive portion P10 and the second conductive portion P20 can be individually energized, and the energization timing and the energization amount for each conductive portion are appropriately controlled. By doing so, a variety of treatment modes can be provided.

Example 4
FIG. 8 shows a fourth embodiment of the present invention. In the present embodiment, the case where the conductive portion provided at a position away from the outer peripheral edge of the pad in the third embodiment is concentrically divided into a plurality is shown. Since other configurations and operations are the same as those in the first and third embodiments, the same components are denoted by the same reference numerals and description thereof is omitted.

  FIG. 8 is a plan view of a pad for a low frequency treatment device according to Example 4 of the present invention (a view seen from the side to be attached to the treatment site). The present embodiment is a modification of the third embodiment, and in the configuration of the third embodiment, the conductive portion P10 provided at a position away from the outer peripheral edge of the pad 10b is concentrically divided into two. is there. A non-conductive portion R10 is provided between the divided conductive portions P10.

  Also in this embodiment, for the two conductive portions P10 provided at positions away from the outer peripheral edge of the pad 10b, the second adhesive portion Q20 is provided in a region surrounding these conductive portions P10. The same effect as in the case of Example 1 can be obtained.

  Further, since the second conductive portion P20 is provided along the outer peripheral edge of the pad 10a and has a large area, the rate of decrease in the contact area with the human body is small when only a little peeled off. This is similar to the case of the third embodiment.

(Example 5)
FIG. 9 shows a fifth embodiment of the present invention. In the present embodiment, an example in which the arrangement shape of the conductive portion and the like provided at a position away from the outer peripheral edge of the pad is improved in the third embodiment. Since other configurations and operations are the same as those in the first and third embodiments, the same components are denoted by the same reference numerals and description thereof is omitted.

FIG. 9 is a plan view of a low-frequency therapeutic device pad according to Example 5 of the present invention (viewed from the side to be attached to the treatment site). As described above, in Example 3, the nonconductive portion R10 is provided along the periphery of the conductive portion P10, and the second conductive portion P20 is further provided outside the nonconductive portion R10. Here, the second conductive portion P20 is configured such that a current is supplied from one place by a cord and the current is distributed throughout. However, if there is a portion having a small cross-sectional area perpendicular to the direction in which the current flows, the impedance becomes high, and there is a risk that the current will be blocked.

  In the pad 10a shown in the third embodiment, the outer peripheral shape of the pad 10a is a shape in which a part of an ellipse is recessed, whereas the outer peripheral shapes of the conductive portion P10 and the nonconductive portion R10 are elliptical. For this reason, a part of the second conductive portion P20 is narrowed, and the impedance becomes high.

  Therefore, in the pad 10c according to the present embodiment, the outer peripheral shape of the conductive portion P10 and the nonconductive portion R10 is also substantially similar to the outer peripheral shape of the pad 10a, and these are arranged near the center of the pad 10c. The second conductive portion P20 is prevented from becoming narrower (see T in the figure).
