[0003] [Patent Document 1] JP 2017-189268 A Summary of the Invention [Problem to be solved by the invention]

[0004] In the electrotherapy device described in Patent Document 1, since the strip is used to peel off one of the pair of conductive adhesive sheets from the end side of the conductive adhesive sheet, it is difficult to remove the electrotherapy device as a whole from the treatment site. Also, if the electrotherapy device is placed on the back or inside the clothes and the strip is not visible, it is difficult to find the strip and difficult to peel it off easily.

[0005] Furthermore, since the treatment device body is heavy, the pair of conductive adhesive sheets are likely to be subjected to stress in the direction of gravity, and therefore, depending on the shape of the pair of conductive adhesive sheets, there is a concern that the conductive adhesive sheets may peel off from the upper side during treatment.

[0006] The present disclosure has been made in consideration of the above-mentioned problems, and an object of the present disclosure is to provide an electric treatment device that is not likely to come off during treatment and can be easily and entirely removed from the treatment area. [Means for solving the problem]

[0007] The electric treatment device according to the present disclosure includes a main body having a first outer edge and a second outer edge facing each other in a first direction in a plan view, a first electrode disposed on the first outer edge side and attached to a living body of a user, and a second electrode disposed on the second outer edge side and attached to a living body of a user. The first electrode and the second electrode are spaced apart in the first direction so that at least the center of the main body is located between them in a plan view. The first electrode includes a first peeling starting point portion that is a peeling starting point, and a first line located on the second electrode side. The second electrode includes a second peeling starting point portion that is a peeling starting point, and a second line located on the first electrode side and facing the first line in the first direction. The electric treatment device includes a gripping portion for simultaneously applying peeling force to the first peeling starting point portion and the second peeling starting point portion.

[0008] According to the above configuration, the first electrode section and the second electrode section are arranged apart in the first direction so that at least the center of the main body section is located between them, and the first line on the second electrode section side included in the first electrode section and the second line on the first electrode section side included in the second electrode section face each other in the first direction in which the first outer edge section and the second outer edge section of the main body section face each other. Therefore, even if the gravity of the main body section acts along the direction in which the first line and the second line extend, the first electrode section and the second electrode section are unlikely to peel off. In addition, even if stress is applied from one side and / or the other side of the first direction, the first electrode section and the second electrode section are unlikely to peel off because the first electrode section and the second electrode section are arranged. This makes it difficult for the electric treatment device to peel off from the treatment site during treatment. In addition, since the first electrode portion and the second electrode portion are not easily peeled off due to stress from the direction in which the first line and the second line extend and stress from the first direction, even if the attachment angle of the first electrode portion and the second electrode portion is misaligned, the electric treatment device is not easily peeled off from the treatment area during treatment.

[0009] Furthermore, by gripping the gripping part and moving it in the peeling direction, a peeling force can be simultaneously applied to the first peeling starting point portion, which is the peeling starting point of the first electrode part, and the second peeling starting point portion, which is the peeling starting point of the second electrode part. This makes it possible to easily and completely remove the electric treatment device from the treatment site.

[0010] In the electrotherapy device based on the present disclosure, the main body includes a first end portion located on one side of a second direction intersecting with the first direction and a second end portion located on the other side of the second direction. In this case, the first line may be arranged adjacent to the first outer edge portion when viewed in a plan view, and the second line may be arranged adjacent to the second outer edge portion when viewed in a plan view. The first peeling starting point may be located at one end of the first line on the one side of the second direction. The second peeling starting point may be located at one end of the second line on the one side of the second direction. The first peeling starting point and the second peeling starting point may be located on the other side of the second direction than the first end portion. The other end of the first line on the other side of the second direction and the other end of the second line on the other side of the second direction may be located on the other side of the second direction than the second end portion. In this case, the first electrode portion may have a first extension line extending from the other end of the first line toward the one side in the first direction toward a first peel end point portion which is an end point of peeling, and extending to the other side in the second direction as it moves toward the one side in the first direction. The second electrode portion may have a second extension line extending from the other end of the second line toward the other side in the second direction as it moves toward the other side in the first direction toward a second peel end point portion which is an end point of peeling. Furthermore, the grip portion may be formed by at least a part of the main body portion.

[0011] According to the above configuration, when the electric treatment device is attached to the treatment site with one side in the second direction facing downward and the other side in the second direction facing upward, the first extension line extending from the other end of the first line toward the first peeling end point and the second extension line extending from the other end of the second line toward the second peeling end point can prevent the gravity of the main body from concentrating on the other end of the first line and the other end of the second line. This makes it difficult for the electric treatment device to come off from the treatment site during treatment.

[0012] Furthermore, as described above, when the electric treatment device is attached to the treatment site with one side in the second direction facing downward and the other side in the second direction facing upward, the first peeling starting point located at one end of the first line and the second peeling starting point located at one end of the second line are located on the other side (upper side) in the second direction than the first end of the main body part. This allows a strong peeling force to be applied to the first peeling starting point and the second peeling starting point simultaneously when the gripping part formed by at least a part of the main body part is gripped and the main body part is moved away from the treatment site. As a result, the electric treatment device can be removed more easily and as a whole.

[0013] In the electrotherapy device based on the present disclosure, the main body includes a first end portion located on one side of a second direction intersecting with the first direction and a second end portion located on the other side of the second direction. In this case, the first line may be arranged adjacent to the first outer edge portion when viewed in a plan view, and the second line may be arranged adjacent to the second outer edge portion when viewed in a plan view. The first peeling starting point may be located at one end of the first line on the one side of the second direction. The second peeling starting point may be located at one end of the second line on the one side of the second direction. The first peeling starting point and the second peeling starting point may be located on the one side of the second direction from the first end portion, and the other end of the first line on the other side of the second direction and the other end of the second line on the other side of the second direction may be located on the other side of the second direction from the second end portion. In this case, the first electrode portion may have a first extension line extending from the other end of the first line toward the one side in the first direction toward a first peel end point portion which is an end point of peeling. The second electrode portion may have a second extension line extending from the other end of the second line toward the other side in the second direction toward the other side in the first direction toward a second peel end point portion which is an end point of peeling. Furthermore, the grip portion may be configured by a knob piece portion that is provided to straddle from the first peel start point to the second peel start point on the one side in the second direction relative to the first end portion when viewed in a plan view, and has a knob portion on the one side in the second direction relative to the first peel start point and the second peel start point.

[0014] According to the above configuration, when the electric treatment device is attached to the treatment site with one side in the second direction facing downward and the other side in the second direction facing upward, the first extension line extending from the other end of the first line toward the first peeling end point and the second extension line extending from the other end of the second line toward the second peeling end point can prevent the gravity of the main body from concentrating on the other end of the first line and the other end of the second line. This makes it difficult for the electric treatment device to come off from the treatment site during treatment.

[0015] Furthermore, as described above, when the electric treatment device is attached to the treatment site with one side in the second direction facing downward and the other side in the second direction facing upward, the first peeling starting point located at one end of the first line and the second peeling starting point located at one end of the second line are located on one side (lower side) in the second direction than the first end of the main body. Also, a gripping piece is provided so as to straddle the first peeling starting point and the second peeling starting point, and the gripping piece is provided with a gripping portion that can be gripped below the first peeling starting point and the second peeling starting point. Therefore, by using the main body as a marker to find the gripping portion located below it and moving the gripping portion in a direction away from the treatment site, a strong peeling force can be applied to the first peeling starting point and the second peeling starting point at the same time. As a result, the electric treatment device can be removed more easily and as a whole.

[0016] In the electrotherapy device based on the present disclosure, the main body includes a first end portion located on one side of a second direction intersecting with the first direction and a second end portion located on the other side of the second direction. In this case, the first line may be arranged adjacent to the first outer edge portion when viewed in a plan view, and the second line may be arranged adjacent to the second outer edge portion when viewed in a plan view. The first electrode portion may have a first straight line portion connected to the first line and extending linearly on the one side of the second direction from the first end portion. The second electrode portion may have a second straight line portion connected to the second line and extending linearly on the one side of the second direction from the first end portion. In this case, the first straight line portion and the second straight line portion may be arranged on the same straight line. The first peeling starting point portion may be constituted by the first straight line portion. The second peeling starting point portion may be constituted by the second straight line portion. Furthermore, the grip portion may be configured with a connection member provided so as to connect the first straight portion and the second straight portion when viewed in a plan view.

[0017] According to the above configuration, when the electric therapy device is attached to the treatment site with one side in the second direction facing downward and the other side in the second direction facing upward, the first straight portion constituting the first peel starting point and the second straight portion constituting the second peel starting point are connected by the connecting member on the lower side of the main body. Therefore, by grasping the connecting member and moving the connecting member in a direction away from the treatment site, a peeling force can be simultaneously applied to the first peel starting point and the second peel starting point over a wide range. As a result, the electric therapy device can be more easily and entirely removed.

[0018] The electrotherapy device according to the present disclosure may include a first connection portion connecting the first line and the main body, and a second connection portion connecting the second line and the main body. In this case, the first line may be located closer to the second outer edge than the first outer edge when viewed in a plan view, and the second line may be located closer to the first outer edge than the second outer edge when viewed in a plan view. The first peeling starting point may be formed by the first line. The second peeling starting point may be formed by the second line. In this case, the gripping portion may be provided on the main body.

[0019] According to the above configuration, by gripping the main body and moving it in a direction away from the treatment site, a peeling force can be simultaneously applied to the first line constituting the first peeling starting point and the second line constituting the second peeling starting point, which makes it easier to remove the electrotherapy device as a whole. Effect of the Invention

[0020] According to the present disclosure, it is possible to provide an electric treatment device that is unlikely to come off during treatment and that can be easily removed as a whole when removed from the treatment site. [Brief description of the drawings]

[0022] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In the embodiments described below, the same or common parts are denoted by the same reference characters in the drawings, and the description thereof will not be repeated.

[0023] (Embodiment 1) Fig. 1 is a plan view of an electric treatment device according to embodiment 1. Fig. 2 is a schematic front view of the electric treatment device according to embodiment 1. An electric treatment device 100 according to embodiment 1 will be described with reference to Figs. 1 and 2.

[0024] As shown in FIGS. 1 and 2, an electrotherapeutic device 100 according to the first embodiment includes a main body section 10, a first electrode section 20, a second electrode section 30, and a pad holding section .

[0025] The electric therapy device 100 is a low-frequency therapy device that relieves the pain of a user by, for example, supplying a low-frequency pulse current to the first electrode unit 20 and the second electrode unit 30 that are in contact with the body surface of the user. The frequency of the low-frequency pulse current is, for example, 1 Hz or more and 1200 Hz or less.

[0026] The main body 10 includes a housing case 11, a circuit section 12, and an operation section 15. The circuit section 12 is housed in the housing case 11. The circuit section 12 is electrically connected to the first electrode section 20 and the second electrode section 30 via electrical paths 61, 62. The circuit section 12 controls the current flowing through the first electrode section 20 and the second electrode section 30, the voltage, and the like.

[0027] The storage case 11 is provided in a substantially box-like shape. When viewed in a plane, the storage case 11 has a substantially rectangular shape with rounded corners. When viewed in a plane, the storage case 11 has a first outer edge portion 13 and a second outer edge portion 14 that face each other in a first direction (DR1 direction). The shape of the storage case 11 is not limited to a substantially rectangular shape when viewed in a plane, and as long as it has a first outer edge portion and a second outer edge portion that face each other in the first direction, an appropriate shape such as a circle, an ellipse, or a trapezoid can be selected when viewed in a plane.

[0028] Furthermore, the housing 11 has a first end 11a and a second end 11b. The first end 11a and the second end 11b face each other in a second direction (DR2 direction) that intersects with the first direction. The second direction is, for example, a direction perpendicular to the first direction. The first end 11a is located on one side of the second direction. The second end 11b is located on the other side of the second direction.

[0029] The operation unit 15 has, for example, a switch for measurement. The operation unit 15 is not limited to a push switch, and may be, for example, a pressure-sensitive (resistance) or proximity (capacitance) touch panel switch. In addition, the housing case 11 may be provided with a display unit in addition to the operation unit 15.

[0030] The first electrode portion 20 and the second electrode portion 30 are arranged at a distance in the first direction so that, when viewed in a plane, at least the central portion of the main body portion 10 is located between the first electrode portion 20 and the second electrode portion 30.

[0031] In this embodiment, the first electrode section 20 and the second electrode section 30 are arranged to sandwich the main body section 10. More specifically, the first electrode section 20 is arranged outside the main body section 10 so that a first line 21 described later is adjacent to the first outer edge section 13 in the first direction. The second electrode section 30 is arranged outside the main body section 10 so that a second line 31 described later is adjacent to the second outer edge section 14 in the first direction.

[0032] The first electrode section 20 and the second electrode section 30 are electrodes for passing a current through the user, and are provided so as to be attachable to the body surface. The first electrode section 20 and the second electrode section 30 may be, for example, a gel pad, or may be a laminate of an adhesive layer and an electrode. By supplying a current to the first electrode section 20 and the second electrode section 30 while the first electrode section 20 and the second electrode section 30 are in contact with the body surface of the user, a current can be passed through the user.

[0033] The first electrode portion 20 has a generally rhombic shape. The first electrode portion 20 has a first line 21 that constitutes an outer edge, and outer lines 22, 23, and 24.

[0034] The first lines 21 are located on the second electrode portion 30 side. The first lines 21 extend in a direction intersecting the first direction. The first lines 21 extend, for example, along the first outer edge portion 13. In the present embodiment, the first lines 21 are provided in a straight line, but are not limited thereto, and may be in a zigzag or curved line.

[0035] The first line 21 has one end 21a and the other end 21b. The one end 21a is located on one side in the second direction, and the other end 21b is located on the other side in the second direction. The one end 21a constitutes a first peel starting point P1 that is a starting point for peeling of the first electrode portion 20.

[0036] The contour line 22 is connected to one end 21a. The contour line 22 extends from the one end 21a toward one side in the first direction and toward the other side in the second direction. Specifically, the contour line 22 is inclined toward the other side in the second direction as it moves from the one end 21a toward one side in the first direction.

[0037] The contour line 23 is connected to the other end 21b. The contour line 23 extends from the other end 21b toward one side in the first direction toward the other side in the second direction. Specifically, the contour line 23 is inclined toward the other side in the second direction toward one side in the first direction from the other end 21b. The contour line 23 is parallel to the contour line 22. An end of the contour line 23 located on the opposite side to the side where the other end 21b is located constitutes a first peeling end point P3 that is the end point of peeling. The contour line 23 corresponds to a first extension line extending from the other end 21b of the first line 21 toward the first peeling end point P3.

[0038] The contour line 24 connects the first peel end point P3 and the contour line 22. The contour line 24 extends from an end of the contour line 22 opposite to the end where the one end 21a is located toward the first peel end point P3. The contour line 24 extends in the first direction and is parallel to the first line 21.

[0039] The second electrode portion 30 has a generally rhombic shape. The second electrode portion 30 has a second line 31 that forms an outer edge, and outer lines 32, 33, and .

[0040] The second lines 31 are located on the first electrode portion 20 side. The second lines 31 face the first lines 21 in the first direction. The second lines 31 extend in a direction intersecting the first direction. The second lines 31 extend, for example, along the second outer edge portion 14. In the present embodiment, the second lines 31 are provided in a straight line, but are not limited thereto, and may be in a zigzag or curved line.

[0041] The second line 31 has one end 31a and the other end 31b. The one end 31a is located on one side in the second direction, and the other end 31b is located on the other side in the second direction. The one end 31a constitutes a second peel starting point P2 which is a starting point for peeling of the second electrode portion 30.

[0042] The contour line 32 is connected to one end 31a. The contour line 32 extends from the one end 31a toward the other side in the first direction and toward the other side in the second direction. Specifically, the contour line 32 is inclined toward the other side in the second direction as it extends from the one end 31a toward the other side in the first direction.

[0043] The contour line 33 is connected to the other end 31b. The contour line 33 extends from the other end 31b toward the other side in the first direction toward the other side in the second direction. Specifically, the contour line 33 is inclined toward the other side in the second direction toward the other side in the first direction from the other end 31b. The contour line 33 is parallel to the contour line 32. An end of the contour line 33 located on the opposite side to the side where the other end 31b is located constitutes a second peeling end point P4 that is the end point of peeling. The contour line 23 corresponds to a second extension line extending from the other end 31b of the second line 31 toward the second peeling end point P4.

[0044] The contour line 34 connects the first peel end point P3 and the contour line 22. The contour line 34 extends from an end of the contour line 32 opposite to the end 31a toward the second peel end point P4. The contour line 34 extends in the first direction and is parallel to the second line 31.

[0045] The pad holding part 40 holds the first electrode part 20 and the second electrode part 30. The pad holding part 40 is, for example, flexible and provided so as to be deformable so as to conform to the body surface. For example, an insulating fabric or the like can be used as the pad holding part 40.

[0046] The pad holding portion 40 has a first holding portion 41, a second holding portion 42, and a connection portion 43. The first holding portion 41 holds the first electrode portion 20. The shape of the first holding portion 41 is approximately the same as the shape of the first electrode portion 20. The second holding portion 42 holds the second electrode portion 30. The shape of the second holding portion 42 is approximately the same as the shape of the second electrode portion 30.

[0047] The connection portion 43 connects the first holding portion 41 and the second holding portion 42. For example, the main body portion 10 is detachably fixed to the connection portion 43. The connection portion 43 is provided with electrical paths 61, 62. In a state in which the main body portion 10 is fixed to the connection portion 43, the first electrode portion 20 and the second electrode portion 30 are electrically connected to the circuit portion 12 by the electrical paths 61, 62.

[0048] When the electric treatment device 100 is attached to the treatment area with one side in the second direction facing downward and the other side in the second direction facing upward, the first outer edge portion 13 and the second outer edge portion 14 of the main body portion 10 become parallel in the up-down direction, and the gravity of the main body portion 10 acts on the electric treatment device 100 toward one side in the second direction.

[0049] Here, in this embodiment, the first electrode section 20 and the second electrode section 30 are arranged at a distance in the first direction so that at least the center of the main body section 10 is located between them, and the first line 21 on the second electrode section 30 side included in the first electrode section 20 and the second line 31 on the first electrode section 20 side included in the second electrode section 30 face each other in the first direction in which the first outer edge section 13 and the second outer edge section 14 of the main body section face each other. Therefore, even if the gravity of the main body section 10 acts along the direction in which the first line 21 and the second line 31 extend, the first electrode section 20 and the second electrode section 30 are not easily peeled off. In addition, even if stress is applied along the first direction, the first electrode section 20 and the second electrode section 30 are arranged at a distance in the first direction, so that the first electrode section 20 and the second electrode section 30 are not easily peeled off. As a result, the electric treatment device 100 is not easily peeled off from the treatment site during treatment. In addition, since the first electrode portion 20 and the second electrode portion 30 are not easily peeled off due to stress from the direction in which the first line 21 and the second line 31 extend and stress from the first direction, even if the attachment angle of the first electrode portion 20 and the second electrode portion 30 is misaligned, the electric therapy device 100 is not easily peeled off from the treatment area during treatment.

[0050] Furthermore, by arranging the first line 21 adjacent to the first outer edge portion 13 and providing along the first outer edge portion 13, and by arranging the second line 31 adjacent to the second outer edge portion 14 and providing along the second outer edge portion 14, the first electrode portion 20 and the second electrode portion 30 can be made less likely to peel off.

[0051] In addition, the contour line 23 (first extension line) extending from the other end 21b of the first line 21 toward the first peeling end point P3 and the contour line 33 (second extension line) extending from the other end 31b of the second line 31 toward the second peeling end point P4 can suppress the concentration of gravity of the main body 10 on the other end 21b of the first line 21 and the other end 31b of the second line 31. This makes it even more difficult for the electric treatment device 100 to peel off from the treatment site during treatment.

[0052] Fig. 3 is a diagram for explaining the operation of removing the electric treatment device according to embodiment 1. The operation of removing the electric treatment device 100 will be explained with reference to Fig. 3.

[0053] 3, one end 21a of the first line 21 and one end 31a of the second line 31 are located on the other side in the second direction of the first end 11a. That is, the one ends 21a and 31a are located on the other side in the second direction of the imaginary line PL1 that passes through the first end 11a.

[0054] The other end 21b of the first line 21 and the other end 31b of the second line 31 are located on the other side in the second direction of the second end 11b. That is, the other ends 21b, 31b are located on the other side in the second direction of the imaginary line PL2 that passes through the second end 11b.

[0055] When removing the electrotherapy device 100, the portion of the main body 10 on the side of the first end 11a is grasped, and the main body 10 is moved toward the other side in the second direction (i.e., upward) as shown by the arrow AR1 in Fig. 3. The portion of the main body 10 on the side of the first end 11a corresponds to a grasp portion 50.

[0056] The connecting portion 43 of the pad holding portion 40 to which the main body portion 10 is fixed is connected to an end of the first holding portion 41 overlapping the first peeling starting point P1 and an end of the second holding portion 42 overlapping the second peeling starting point P2. This allows a peeling force to be applied simultaneously to the first peeling starting point P1 and the second peeling starting point P2 by gripping the gripping portion 50 and moving the main body portion 10. This allows the electric treatment device to be easily and entirely removed from the treatment site.

[0057] Furthermore, the portion of the first electrode section 20 excluding the first peel starting point P1 is located on the other side in the second direction from the first peel starting point P1, and the portion of the second electrode section 30 excluding the second peel starting point P2 is located on the other side in the second direction from the second peel starting point P2. In addition, by providing the above-mentioned first extension line (outline line 23) and second extension line (outline line 33), a force acting on the other side in the second direction is more likely to be directed toward the first peel end point P3 and the second peel end point P4. As a result, the electrotherapy device can be more easily and entirely removed.

[0058] (Embodiment 2) Fig. 4 is a plan view of an electric treatment device according to embodiment 2. An electric treatment device 100A according to embodiment 2 will be described with reference to Fig. 4.

[0059] 4, the electric treatment device 100A according to the second embodiment differs from the electric treatment device 100 according to the first embodiment in the positions of the first and second separation starting points P1 and P2, and in the configuration of the gripping part 50A. The other configurations are almost the same.

[0060] Also in the second embodiment, the first electrode section 20 and the second electrode section 30 have a substantially diamond shape. In a plan view, the first lines 21 of the first electrode section 20 are disposed adjacent to the first outer edge section 13 of the main body section 10, and the second lines 31 of the second electrode section 30 are disposed adjacent to the second outer edge section 14 of the main body section 10.

[0061] One end 21a of the first line 21 constitutes a first peel starting point P1, and one end 31a of the second line 31 constitutes a second peel starting point P2. The first peel starting point P1 and the second peel starting point P2 are located on one side in the second direction of the first end 11a of the main body portion 10. The other end 21b of the first line 21 and the other end 31b of the second line 31 are located on the other side in the second direction of the second end 11b of the main body portion 10.

[0062] Additionally, the contour line 23 (first extending line) extends from the other end 21b of the first line 21 toward one side in the first direction toward the first peel end point P3, and then extends to the other side in the second direction. Similarly, the contour line 33 (second extending line) extends from the other end 31b of the second line 31 toward the other side in the first direction toward the second peel end point P4.

[0063] The gripping portion 50A is configured with a gripping piece 51. The gripping piece 51 is located on one side in the first direction from the first end portion 11a of the main body portion 10. The gripping piece 51 is provided to straddle from the first peel starting point P1 to the second peel starting point P2 in a plan view. The gripping piece 51 has a gripping portion 52 on the tip side (the side opposite to the side where the main body portion 10 is located). The gripping portion 52 is located on one side in the second direction from the first peel starting point P1 and the second peel starting point P2.

[0064] The gripping piece 51 is made of, for example, a sheet-like member. The gripping piece 51 has a desired strength so as not to break when the gripping portion 52 is gripped and moved. The gripping piece 51 is not provided with a conductive layer for attaching it to the surface of the user's body.

[0065] Also in embodiment 2, when electric treatment device 100A is attached to the treatment area with one side in the second direction facing downward and the other side in the second direction facing upward, first outer edge portion 13 and second outer edge portion 14 of main body portion 10 become parallel in the vertical direction, and the gravity of main body portion 10 acts on electric treatment device 100A toward one side in the second direction.

[0066] In this case, similarly to the first embodiment, the first electrode section 20 and the second electrode section 30 are arranged spaced apart in the first direction so that at least the center of the main body section 10 is located between them, and the first line 21 on the second electrode section 30 side included in the first electrode section 20 and the second line 31 on the first electrode section 20 side included in the second electrode section 30 face each other in the first direction in which the first outer edge section 13 and the second outer edge section 14 of the main body section face each other. Therefore, the first electrode section 20 and the second electrode section 30 are less likely to come off, and the electric treatment device 100A is less likely to come off from the treatment site during treatment.

[0067] In addition, the contour line 23 (first extension line) extending from the other end 21b of the first line 21 toward the first peeling end point P3 and the contour line 33 (second extension line) extending from the other end 31b of the second line 31 toward the second peeling end point P4 can suppress the concentration of gravity of the main body 10 on the other end 21b of the first line 21 and the other end 31b of the second line 31. This makes it even more difficult for the electric treatment device 100A to peel off from the treatment site during treatment.

[0068] When removing the electric therapy device 100A, the gripping portion 52 located below the main body 10 (one side in the first direction) is found using the main body 10 as a landmark, and the gripping portion 52 is moved in a direction away from the treatment site (the other side in the second direction), so that a strong peeling force can be simultaneously applied to the first peeling starting point P1 and the second peeling starting point P2. As a result, the electric therapy device 100A can be removed more easily and as a whole.

[0069] (Embodiment 3) Fig. 5 is a plan view of an electrotherapy device according to embodiment 3. An electrotherapy device 100B according to embodiment 3 will be described with reference to Fig. 5.

[0070] 5, an electric treatment device 100B according to embodiment 3 is different from an electric treatment device 100 according to embodiment 1 in the shapes of the first electrode section 20 and the second electrode section 30, and in the configuration of a grip section 50B. The other configurations are almost the same.

[0071] The first electrode section 20 and the second electrode section 30 have a substantially rectangular shape. In plan view, the first line 21 of the first electrode section 20 is disposed adjacent to the first outer edge section 13 of the main body section 10, and the second line 31 of the second electrode section 30 is disposed adjacent to the second outer edge section 14 of the main body section 10.

[0072] One end 21a of the first line 21 and one end 31a of the second line 31 are located on one side in the second direction of the first end 11a of the main body portion 10. The other end 21b of the first line 21 and the other end 31b of the second line 31 are located on the other side in the second direction of the second end 11b of the main body portion 10.

[0073] The contour line 22 (first straight portion) is connected to one end 21a of the first line 21. The contour line 22 extends linearly on one side in the second direction from the first end 11a. The contour line 22 extends approximately parallel to the second direction.

[0074] The contour line 23 is connected to the other end 21b of the first line 21. The contour line 23 extends linearly in parallel to the contour line 22 on the other side in the second direction relative to the second end 11b.

[0075] The contour line 32 (second straight portion) is connected to one end 31a of the second line 31. The contour line 32 extends linearly on one side in the second direction from the first end 11a. The contour line 32 extends approximately parallel to the second direction. The contour line 32 is disposed in the same straight line as the contour line 22.

[0076] The contour line 33 is connected to the other end 31b of the second line 31. The contour line 33 extends linearly on the other side in the second direction from the second end 11b so as to be parallel to the contour line 32. The contour line 33 is disposed in the same straight line as the contour line 23.

[0077] In this case, the first peel start point P1 is defined by the contour line 22, and the second peel start point P2 is defined by the contour line 32. The first peel end point P3 is defined by the contour line 23, and the second peel end point P4 is defined by the contour line 33.

[0078] The grip portion 50B is configured by a connection member 55 provided so as to entirely connect the outline line 22 and the outline line 32 when viewed from above.

[0079] The connecting member 55 may be provided in a rod shape or a flat shape, for example. The connecting member 55 may be made of a resin member such as plastic, or may be made of a metal member.

[0080] Also in embodiment 3, when electric treatment device 100B is attached to the treatment area with one side in the second direction facing downward and the other side in the second direction facing upward, first outer edge portion 13 and second outer edge portion 14 of main body portion 10 become parallel in the vertical direction, and the gravity of main body portion 10 acts on electric treatment device 100B toward one side in the second direction.

[0081] In this case, similarly to the first embodiment, the first electrode section 20 and the second electrode section 30 are arranged spaced apart in the first direction so that at least the center of the main body section 10 is located between them, and the first line 21 on the second electrode section 30 side included in the first electrode section 20 and the second line 31 on the first electrode section 20 side included in the second electrode section 30 face each other in the first direction in which the first outer edge section 13 and the second outer edge section 14 of the main body section face each other. Therefore, the first electrode section 20 and the second electrode section 30 are less likely to come off, and the electric treatment device 100B is less likely to come off from the treatment site during treatment.

[0082] When removing the electric therapy device 100B, the connecting member 55 located below the main body 10 (one side in the second direction) is found using the main body 10 as a landmark, and the connecting member 55 is grasped and moved in a direction away from the treatment site (the other side in the second direction), so that a strong peeling force can be simultaneously applied to the first peeling starting point P1 and the second peeling starting point P2 over a wide range. As a result, the electric therapy device 100B can be removed more easily and as a whole.

[0083] (Embodiment 4) Fig. 6 is a plan view of an electric treatment device according to embodiment 4. Fig. 7 is a schematic front view of an electric treatment device according to embodiment 4. An electric treatment device 100C according to embodiment 4 will be described with reference to Figs. 6 and 7.

[0084] As shown in Figures 6 and 7, when compared with the electric treatment device 100 of embodiment 1, the electric treatment device 100C of embodiment 3 differs in the positional relationship between the first electrode section 20 and the second electrode section 30 and the main body section 10, the configuration of the pad holding section 40C, and the configuration of the gripping section 50C.

[0085] The first electrode portion 20 and the second electrode portion 30 have a substantially rectangular shape. In a plan view, the first lines 21 of the first electrode portion 20 and the second lines 31 of the second electrode portion 30 overlap with the main body portion 10. In a plan view, the first lines 21 are located closer to the second outer edge portion 14 than the first outer edge portion 13, and the second lines 31 are located closer to the first outer edge portion 13 than the second outer edge portion 14.

[0086] The pad holding portion 40 has a first connecting portion 45 and a second connecting portion 46 instead of the connecting portion 43 according to the first embodiment.

[0087] The first connection part 45 connects the first line 21 and the main body part 10. The first connection part 45 is a part folded back to one side in the first direction from the end part 41a of the first holding part 41 located on the main body part 10 side. The first connection part 45 is fixed to a part of the back surface 10c of the main body part 10 located on the first outer edge part 13 side.

[0088] The second connection part 46 connects the second line 31 and the main body part 10. The second connection part 46 is a part folded back to the other side in the first direction from the end part 42a of the second holding part 42 located on the main body part 10 side. The second connection part 46 is fixed to a part of the back surface 10c of the main body part 10 located on the second outer edge part 14 side.

[0089] An electrical path (not shown) is provided in the first connection portion 45 and the second connection portion 46, and the first electrode portion 20 and the second electrode portion 30 are electrically connected to the circuit portion 12 via the electrical path.

[0090] In this case, a first peel start point P1 is formed by the first line 21, and a second peel start point P2 is formed by the second line 31. A first peel end point P3 is formed by the contour line 24, and a second peel end point P4 is formed by the contour line 34.

[0091] Also in embodiment 4, when electric treatment device 100C is attached to the treatment area with one side in the second direction facing downward and the other side in the second direction facing upward, first outer edge portion 13 and second outer edge portion 14 of main body portion 10 become parallel in the vertical direction, and the gravity of main body portion 10 acts on electric treatment device 100C toward one side in the second direction.

[0092] As in the first embodiment, the first electrode section 20 and the second electrode section 30 are arranged at a distance in the first direction so that at least the center of the main body section 10 is located between them, and the first line 21 on the second electrode section 30 side included in the first electrode section 20 and the second line 31 on the first electrode section 20 side included in the second electrode section 30 face each other in the first direction in which the first outer edge section 13 and the second outer edge section 14 of the main body section face each other. Therefore, the first electrode section 20 and the second electrode section 30 are not easily peeled off, and the electric treatment device 100 is not easily peeled off from the treatment site during treatment. In addition, in the fourth embodiment, the first electrode section 20 and the second electrode section 30 have a shape that is not easily peeled off even when stress is applied from any direction when viewed in a plane, so that the degree of freedom in the attachment direction is high.

[0093] When removing the electric treatment device 100C, the main body 10 is grasped and moved in a direction away from the treatment site (in the normal direction of the back surface 10c), so that a peeling force is simultaneously applied to the first line 21 constituting the first peeling starting point P1 and the second line 31 constituting the second peeling starting point P2, as shown by the arrows in Fig. 6. As a result, the electric treatment device 100C can be removed more easily and as a whole.

[0094] (Other variations) In the above-mentioned first and second embodiments, the outline lines 23, 33 are inclined with respect to the first direction, but the present invention is not limited to this. The outline lines 23, 33 may be parallel to the first direction. The outline line 23 may be inclined so as to approach one side of the first direction toward the other side of the second direction, and the outline line 33 may be inclined so as to approach the other side of the second direction toward the other side of the first direction. The outline lines 22, 23 are not limited to straight lines and may be curved lines.

[0095] In the above-described third embodiment, the outline lines 23, 33 are parallel to the first direction, but the present invention is not limited to this. The outline lines 23, 33 may be inclined toward the other side in the second direction as they move outward in the first direction, as in the first and second embodiments.
