Description

[Technical field]

[0001] The present disclosure relates to electrotherapy devices. [Background technology]

[0002] As a conventional electric therapy device, JP 2007-44479 A (Patent Document 1) discloses a low-frequency therapy device consisting of a flat bag filled with inorganic beads, on one side of which a skin-contact electrode portion made of a pair of conductive fabrics and a terminal portion for conducting a low-frequency current to the electrode portion are integrally combined.

[0003] Furthermore, JP 2017-189268 A (Patent Document 2) discloses an electric treatment device comprising a pair of conductive adhesive sheets spaced apart in a linear fashion, and a treatment device main body (main body portion) arranged to straddle the pair of conductive adhesive sheets, and a clip is provided on one of the conductive adhesive sheets of the pair. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2007-44479 A [Patent Document 2] JP 2017-189268 A Summary of the Invention [Problem to be solved by the invention]

[0005] In the electric therapy device described in Patent Document 1, the weight of the beads packed in the bag presses the skin contact electrode part against the body surface of the user during use. Therefore, the location where the electric therapy device can be placed is limited, such as placing the electric therapy device so that it straddles the shoulders in the front-back direction. In addition, depending on the location where the electric therapy device is placed, it is difficult to stably attach the electric therapy device to the body surface.

[0006] In the electrotherapy device described in Patent Document 2, the conductive adhesive sheet on one side, the main body, and the conductive adhesive sheet on the other side of a pair of conductive adhesive sheets are peeled off in order from the end side of the conductive adhesive sheet on one side using a piece of material, so 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 clothing and the piece is not visible, it may be difficult to find the piece and difficult to peel it off.

[0007] 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 can be attached to a body surface, is easily detached from the body surface, and is highly convenient. [Means for solving the problem]

[0008] The electrotherapy device according to the present disclosure includes a tubular member and an electrode section provided on the tubular member so as to be attached to a body surface of a user. The tubular member has a first section located on the side of the body surface of the user in a used state and a second section located on the opposite side to the side on which the body surface of the user is located. The first section has a first surface facing the body surface of the user in a used state. The electrode section is provided on the first surface.

[0009] According to the above configuration, the electric therapy device can be attached to the body surface by the electrode part. When removing the battery-powered treatment device, the second part located on the opposite side to the first part where the electrode part is provided can be grasped, or the tubular member can be easily grasped by passing a finger or the like through the inside of the tubular member. By moving the tubular member in a direction away from the body surface, a peeling force can be applied from both ends of the electrode part in the circumferential direction toward the center of the electrode part. As a result, the electric therapy device can be easily removed, improving convenience.

[0010] The electrotherapy device according to the present disclosure may further include a main body fixed to the tubular member. In this case, the main body may be fixed to the second portion such that at least a portion of the main body overlaps the second portion.

[0011] According to the above configuration, by grasping the main body and moving it in a direction away from the body surface, a peeling force is applied to the electrode portion, and the electrotherapy device can be entirely and easily removed from the body surface.

[0012] In the electrotherapy device according to the present disclosure, the tubular member may include a first tubular member and a second tubular member arranged at a distance from each other. Each of the first tubular member and the second tubular member has the first portion and the second portion. The electrode portion may include a first electrode portion provided on the first surface of the first tubular member and a second electrode portion provided on the first surface of the second tubular member. In this case, the main body portion may be fixed to the second portion of the first tubular member and the second portion of the second tubular member so as to straddle the first tubular member and the second tubular member.

[0013] According to the above configuration, the main body is fixed to the first and second tubular members arranged at a distance from each other so as to straddle the first and second tubular members. Therefore, by grasping the main body and moving it in a direction away from the body surface, a peeling force can be simultaneously applied to the first and second electrodes, and the electrotherapy device can be easily and entirely removed from the body surface.

[0014] In the electrotherapy device according to the present disclosure, the first cylindrical axis of the first cylindrical member and the second cylindrical axis of the second cylindrical member may be parallel to each other. The first cylindrical axis and the second cylindrical axis may be perpendicular to a direction in which the first cylindrical member and the second cylindrical member are arranged in a plan view.

[0015] According to the above configuration, by gripping the main body and moving it in a direction away from the body surface, a peeling force can be applied to both ends of the first electrode portion provided on the first tubular member and the second electrode portion provided on the second tubular member in the direction in which the first tubular member and the second tubular member are aligned, toward the inside in the circumferential direction of the first tubular member and the second tubular member, thereby making it possible to easily remove the main body portion, the first tubular member, and the second tubular member as a whole from the body surface.

[0016] In the electric treatment device based on the present disclosure, the tubular member may include a first tubular member and a second tubular member arranged at an interval in a first direction. Each of the first tubular member and the second tubular member has the first portion and the second portion. The electrode portion may include a first electrode portion provided on the first surface of the first tubular member and a second electrode portion provided on the first surface of the second tubular member. The electric treatment device may further include a fixing member to which the main body portion is fixed. The fixing member may include a first fixing portion fixed to the second portion of the first tubular member and a second fixing portion fixed to the second portion of the second tubular member. In this case, one end side of the main body portion in the arrangement direction in which the first tubular member and the second tubular member are aligned may be fixed to the first fixed portion, and the other end side of the main body portion in the arrangement direction may be fixed to the second fixed portion, thereby fixing the main body portion to the first tubular member and the second tubular member via the fixing member.

[0017] According to the above configuration, the main body is fixed so as to straddle the first fixing part fixed to the first tubular member and the second fixing part fixed to the second tubular member. Therefore, by grasping the main body and moving it in a direction away from the body surface, a peeling force can be simultaneously applied to the first electrode part and the second electrode part, and the electrotherapy device can be easily and entirely removed from the body surface.

[0018] In the electric treatment device based on the present disclosure, the first cylindrical axis of the first tubular member and the second cylindrical axis of the second tubular member may be parallel to the arrangement direction when viewed in a plane.

[0019] According to the above configuration, by gripping the main body and moving it in a direction away from the body surface, a peeling force can be applied to both ends of the first electrode portion provided on the first tubular member and the second electrode portion provided on the second tubular member in the axial direction, toward the inside in the circumferential direction of the first tubular member and the second tubular member, respectively. This allows the main body portion, the first tubular member, and the second tubular member to be removed as a whole and easily from the body surface.

[0020] In the electrotherapy device according to the present disclosure, the first portion may have a length parallel to the axial direction of the cylindrical member that is constant in the circumferential direction, and the second portion may have a portion where the length parallel to the axial direction is shorter than that of the first portion.

[0021] By forming the second portion in the above-described shape, the area of ​​the cylindrical member can be reduced, making it possible to reduce the weight of the electrotherapy device and reduce the manufacturing costs. Effect of the Invention

[0022] According to the present disclosure, it is possible to provide a highly convenient electric treatment device that can be attached to a body surface and is easily detachable from the body surface. [Brief description of the drawings]

[0024] 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.

[0025] (Embodiment 1) Fig. 1 is a schematic diagram of an electric treatment device according to embodiment 1. With reference to Fig. 1, an electric treatment device 100 according to embodiment 1 will be described.

[0026] As shown in FIG. 1, an electrotherapeutic device 100 according to the first embodiment includes a main body portion 10, a tubular member 20, two electrode portions 30, two terminal portions 40, and two wiring portions 41.

[0027] 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 electrode section 30 that contacts 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.

[0028] The main body 10 is disposed at a position away from the cylindrical member 20. The main body 10 includes a housing case 11 and a circuit section 12. The housing case 11 has a generally box-like shape and houses the circuit section 12 therein. The circuit section 12 is electrically connected to the electrode section 30 via a wiring section 41 and a terminal section 40. The circuit section 12 controls the current and voltage flowing through the electrode section 30. The circuit section 12 is a circuit board on which a desired circuit is formed.

[0029] The cylindrical member 20 is formed in a cylindrical shape and has a cylindrical axis AX. The cylindrical member 20 is formed, for example, in a cylindrical shape. Note that the shape of the cylindrical member 20 is not limited to a cylindrical shape as long as it is formed in a cylindrical shape that is continuous in the circumferential direction while ensuring an area in which the electrode portion 30 is provided.

[0030] The cylindrical member 20 has a first portion 21 that is located on the side of the user's body surface when in use, and a second portion 22 that is located on the opposite side to the side located on the side of the user's body surface when in use. The first portion 21 and the second portion 22 are continuous in the circumferential direction to form the cylindrical member 20.

[0031] The first portion 21 has an outer surface 21a and an inner surface 21b. The outer surface 21a corresponds to a first surface that faces the body surface of the user when in use. The second portion 22 has an outer surface 22a and an inner surface 21b. The outer surface 21a and the outer surface 22a are continuous in the circumferential direction and constitute the outer surface of the tubular member 20. The inner surface 21b and the inner surface 22b are continuous in the circumferential direction and constitute the inner surface of the tubular member 20.

[0032] Each of the two electrode sections 30 is provided on the cylindrical member 20 so as to be attached to the surface of the user's body. The two electrode sections 30 are arranged side by side in a direction parallel to the cylindrical axis AX. The electrode section 30 may be, for example, a gel pad, or may have both an adhesive layer and an electrode.

[0033] The electrode portion 30 is provided on the outer surface 21a of the first portion 21. The electrode portion 30 has a substantially rectangular shape. More specifically, the electrode portion 30 has a substantially rectangular shape in which a pair of sides facing each other in the circumferential direction are substantially parallel to the direction of the cylinder axis AX. The shape of the electrode portion 30 is not limited to a rectangular shape, and may be any suitable shape such as a circular shape, an elliptical shape, a polygonal shape, or an oval shape. Furthermore, the line constituting the outer edge of the electrode portion is not limited to a straight line, and may be a zigzag shape or a curved shape.

[0034] The two terminal parts 40 are provided to correspond to the two electrode parts 30. The two terminal parts 40 are provided on the inner surface 21b side of the first part 21. This allows the terminal part 40 to be provided at a position close to the electrode part 30. The wiring part 41 can be detachably attached to the terminal part 30. Note that, in the present embodiment, the case where the two wiring parts 41 are connected to the two corresponding terminal parts 40 is illustrated as an example, but is not limited to this. One wiring part 41 may be provided so as to branch into two on the terminal part 40 side, and each branched part may be connected to the corresponding terminal part 40.

[0035] In this embodiment, the electric therapy device 100 can be attached to the body surface by the electrode section 30. When removing the battery-powered therapy device 100, the second section 22 located on the opposite side to the first section 21 where the electrode section 30 is provided can be grasped, or the tubular member 20 can be easily grasped by passing a finger or the like through the inside of the tubular member 20. By moving the tubular member 20 in a direction away from the body surface, a peeling force can be applied from both ends of the electrode section 30 in the circumferential direction toward the center of the electrode section 30. As a result, the electric therapy device can be easily removed, improving convenience.

[0036] In the first embodiment, the case where two electrode sections 30 are provided on the cylindrical member 20 has been described as an example, but the present invention is not limited thereto. Two units, each of which has one electrode section 30 provided on one cylindrical member 20, may be used, and each of the two units may be connected to the circuit section 12 of the main body section 10 via the wiring section 41. The number of electrode sections 30 may be three or more. In addition, the case where the multiple electrode sections 30 are arranged side by side in the direction of the cylindrical axis AX has been described as an example, but the present invention is not limited thereto, and the electrode sections 30 may be arranged side by side in the circumferential direction of the cylindrical member 20.

[0037] (Embodiment 2) Fig. 2 is a schematic diagram 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. 2. As shown in Fig. 2, electric treatment device 100A according to embodiment 2 includes a main body portion 10, a cylindrical member 20, and an electrode portion 30.

[0038] The main body 10 includes a housing case 11 and a circuit section 12. The housing case 11 has a generally box-like shape and houses the circuit section 12 therein. The housing case 11 has a first end 13 and a second end 14 on either side in a first direction (DR1). The first direction is the direction in which the first end 13 and the second end 14 face each other.

[0039] The first end 13 is located on one side in the first direction, and the second end 14 is located on the other side in the first direction. The first end 13 and the second end 14 extend in a substantially straight line when viewed in a plan view. The first end 13 and the second end 14 extend in a direction perpendicular to the first direction.

[0040] The circuit unit 12 is electrically connected to the electrode unit 30 via an electrical path (not shown). The electrical path is provided in each of the first cylindrical member 210 and the second cylindrical member 220 described below. The circuit unit 12 controls the current and voltage flowing through the electrode unit 30. The circuit unit 12 is a circuit board on which a desired circuit is formed.

[0041] The cylindrical member 20 includes a first cylindrical member 210 and a second cylindrical member 220. The first cylindrical member 210 and the second cylindrical member 220 are arranged at a distance from each other. The arrangement direction in which the first cylindrical member 210 and the second cylindrical member 220 are arranged is parallel to the first direction.

[0042] The first cylindrical member 210 is formed in a cylindrical shape and has a cylindrical axis AX1 (first cylindrical axis). The first cylindrical member 210 is formed in, for example, a cylindrical shape. Note that the shape of the first cylindrical member 210 is not limited to a cylindrical shape as long as it is formed in a cylindrical shape that is continuous in the circumferential direction while ensuring an area in which the first electrode portion 310 described later is provided.

[0043] The first cylindrical member 210 has a first portion 211 that is located on the side of the user's body surface when in use, and a second portion 212 that is located on the opposite side to the side located on the side of the user's body surface when in use. The first portion 211 and the second portion 212 are continuous in the circumferential direction to form the first cylindrical member 210.

[0044] The first portion 211 has an outer surface 211a and an inner surface 211b. The outer surface 211a corresponds to a first surface that faces the body surface of the user when in use. The second portion 212 has an outer surface 212a and an inner surface 211b. The outer surface 211a and the outer surface 212a are continuous in the circumferential direction and constitute the outer surface of the first cylindrical member 210. The inner surface 211b and the inner surface 212b are continuous in the circumferential direction and constitute the inner surface of the first cylindrical member 210.

[0045] The second cylindrical member 220 is formed in a cylindrical shape and has a cylindrical axis AX2 (second cylindrical axis). The second cylindrical member 220 is formed in, for example, a cylindrical shape. Note that the shape of the second cylindrical member 220 is not limited to a cylindrical shape as long as it is formed in a cylindrical shape that is continuous in the circumferential direction while ensuring an area in which the second electrode portion 320 described later is provided.

[0046] The second cylindrical member 220 has a first portion 221 that is located on the side of the user's body surface when in use, and a second portion 222 that is located on the opposite side to the side located on the side of the user's body surface when in use. The first portion 221 and the second portion 222 are continuous in the circumferential direction to form the second cylindrical member 220.

[0047] The first portion 221 has an outer surface 221a and an inner surface 221b. The outer surface 221a corresponds to a first surface that faces the body surface of the user when in use. The second portion 222 has an outer surface 222a and an inner surface 222b. The outer surface 221a and the outer surface 222a are continuous in the circumferential direction and constitute the outer surface of the second cylindrical member 220. The inner surface 221b and the inner surface 222b are continuous in the circumferential direction and constitute the inner surface of the second cylindrical member 220.

[0048] The first cylindrical member 210 and the second cylindrical member 220 are disposed so that the cylindrical axes AX1 and AX2 are perpendicular to the arrangement direction.

[0049] The electrode section 30 is provided on the tubular member 20 so as to be attachable to the surface of the user's body. The electrode section 30 includes a first electrode section 310 and a second electrode section 320. The first electrode section 310 and the second electrode section 320 may be, for example, a gel pad, or may have both an adhesive layer and an electrode.

[0050] The first electrode portion 310 is provided on an outer surface 211a of the first portion 211 of the first cylindrical member 210. The first electrode portion 310 has a substantially rectangular shape. The first electrode portion 310 has a first line 311, a second line 312, a third line 313, and a fourth line 314 that form an outer edge.

[0051] The first lines 311 and the second lines 312 are arranged side by side in the circumferential direction of the first cylindrical member 210. The first lines 311 are located closer to the main body portion 10 than the second lines 312. The first lines 311 and the second lines 312 extend in a direction parallel to the cylindrical axis AX1. The first lines 311 and the second lines 312 are approximately parallel to the first end portion 13 of the main body portion 10.

[0052] Each of the first line 311 and the second line 312 has a one-side end portion located on one side in a direction parallel to the cylindrical axis AX1, and a other-side end portion located on the other side in a direction parallel to the cylindrical axis AX1.

[0053] The third line 313 connects the one-side ends of the first line 311 and the second line 312. The fourth line 314 connects the other-side ends of the first line 311 and the second line 312. The third line 313 and the fourth line 314 extend along the circumferential direction of the first cylindrical member 210.

[0054] The second electrode portion 320 is provided on the outer surface 221a of the first portion 221 of the second cylindrical member 220. The second electrode portion 320 has a substantially rectangular shape. The second electrode portion 320 has a first line 321, a second line 322, a third line 323, and a fourth line 324 that form an outer edge.

[0055] The first line 321 and the second line 322 are arranged side by side in the circumferential direction of the second cylindrical member 220. The first line 321 is located closer to the main body portion 10 than the second line 322. The first line 321 and the second line 322 extend in a direction parallel to the cylindrical axis AX2. The first line 321 and the second line 322 are approximately parallel to the second end portion 14 of the main body portion 10.

[0056] Each of the first line 321 and the second line 322 has a one-side end portion located on one side in a direction parallel to the cylindrical axis AX2, and a other-side end portion located on the other side in a direction parallel to the cylindrical axis AX2.

[0057] The third line 323 connects the one-side ends of the first line 321 and the second line 322. The fourth line 324 connects the other-side ends of the first line 321 and the second line 322. The third line 323 and the fourth line 324 extend along the circumferential direction of the second cylindrical member 220.

[0058] The main body 10 is fixed to the second portion (212, 222) of the cylindrical member 20 such that at least a portion of the main body 10 overlaps the second portion (212, 222) of the cylindrical member 20. Specifically, the main body 10 is fixed to the second portion (212, 222) so as to straddle the first cylindrical member 210 and the second cylindrical member 220. More specifically, the first end 13 side of the main body 10 is fixed to the outer surface 212a of the second portion 212 of the first cylindrical member 210, and the second end 14 side of the main body 10 is fixed to the outer surface 222a of the second portion 222 of the second cylindrical member 220. The main body 10 may be fixed to the inner surfaces 212b, 222b of the second portions 212, 222.

[0059] The electric therapy device 100A may be attached to the body surface so that the cylinder axis AX1 and the cylinder axis AX2 are substantially parallel to the up-down direction (vertical direction). In this case, the gravity of the main body 10 acts on the electric therapy device 100A downward, that is, toward one side in the second direction (DR2 direction) perpendicular to the first direction (more specifically, toward one side in the direction parallel to the cylinder axes AX1 and AX2).

[0060] The first electrode section 310 and the second electrode section 320 include, for example, a conductive gel or an adhesive layer, and buffer the stress from the first direction and the stress from the second direction, making the first electrode section 310 and the second electrode section 320 less likely to peel off from the body surface.

[0061] Furthermore, the first electrode section 310 includes a first line 311 and a second line 312 extending generally parallel to the direction in which the first end 13 of the main body section 10 extends, and the second electrode section 320 includes a first line 321 and a second line 322 extending generally parallel to the direction in which the second end 14 extends. This makes it more difficult for the first electrode section 310 and the second electrode section 320 to come off, and makes it more difficult for the electric treatment device 100A to come off from the treatment site during treatment.

[0062] Fig. 3 is a diagram showing a state in which the electric treatment device according to the embodiment 2 is removed. With reference to Fig. 3, the operation when the electric treatment device 100A according to the embodiment 2 is removed will be described.

[0063] As shown in Fig. 3, when removing the electric treatment device 100A from the body surface, the main body 10 is grasped and moved in a direction away from the body surface. This allows a peeling force to be simultaneously applied to the first electrode section 310 and the second electrode section 320 on the first cylindrical member 210 side and the second cylindrical member 220 side, respectively.

[0064] Specifically, on the side of the first tubular member 210, as shown by arrows AR1 and AR2 in the figure, a peeling force can be applied to each of both ends (more specifically, the first line 311 and the second line 312) of the first electrode portion 310 in the arrangement direction, toward the inside in the circumferential direction of the first tubular member 210.

[0065] On the second tubular member 220 side, as shown by arrows AR3 and AR4 in the figure, a peeling force can be applied to each of both ends of the second electrode portion 320 in the arrangement direction (more specifically, the first line 311 and the second line 312) in the circumferential inward direction of the second tubular member 220.

[0066] In this manner, the first electrode section 310 and the second electrode section 320 can be simultaneously peeled off from the body surface, and the entire electric treatment device 100A can be removed from the body surface. As a result, the electric treatment device can be easily removed.

[0067] In the above description, the electric therapy device 100A is attached to the body surface so that the cylinder axis AX1 and the cylinder axis AX2 are substantially parallel to the up-down direction (vertical direction), but the direction in which the electric therapy device 100 is attached is not particularly limited as long as a current can be passed through the body surface via the conductive layer 30. Even if the cylinder axis AX1 and the cylinder axis AX2 are oriented in a direction other than the up-down direction, the electric therapy device 100A can be easily and entirely removed from the body surface by moving the main body 10 in a direction away from the body surface. The same applies to the following third and fourth embodiments.

[0068] (Embodiment 3) Fig. 4 is a schematic diagram of an electric treatment device according to embodiment 3. An electric treatment device 100B according to embodiment 3 will be described with reference to Fig. 4.

[0069] As shown in FIG. 4, an electrotherapy device 100B according to the third embodiment is different from an electrotherapy device 100A according to the second embodiment in the configurations of a cylindrical member 20 and an electrode section 30. As shown in FIG.

[0070] The cylindrical member 20 is composed of a single cylindrical member. The cylindrical member 20 has a cylindrical axis AX3. When viewed in a plan view, the cylindrical axis AX3 is a direction perpendicular to a first direction in which the first end 13 and the second end 14 of the main body 10 face each other. The cylindrical member 20 includes a first portion 21 located on the side of the user's body surface in a used state and a second portion 22 located on the opposite side to the side on which the user's body surface is located. The first portion 21 and the second portion 22 are continuous in the circumferential direction to form the cylindrical member 20. Two electrode portions 30 are provided on the cylindrical member 20.

[0071] The first portion 21 has an outer surface 21a and an inner surface 21b, and the second portion 22 has an outer surface 22a and an inner surface 22b. The outer surface 21a of the first portion 21 corresponds to a first surface that faces the body surface of the user in the used state.

[0072] Each of the two electrode sections 30 has a substantially rectangular shape. Each electrode section 30 has a first line 31, a second line 32, a third line 33, and a fourth line 34 that form an outer edge. Note that the first to fourth lines 31 to 34 have substantially the same configuration as the first to fourth lines 311 to 314 according to the second embodiment, and therefore a description thereof will be omitted.

[0073] The main body portion 10 is disposed so as to overlap the electrode portion 30 in a plan view. The main body portion 10 is disposed on the opposite side in the circumferential direction of the cylindrical member 20 with respect to the electrode portion 30. The main body portion 10 is fixed to the second portion 22 so as to overlap the second portion 22 as a whole. The main body portion 10 may be fixed to an outer surface 22a of the second portion 22, or may be fixed to an inner surface 22b of the second portion 22.

[0074] The electric therapy device 100B may be attached to the body surface so that the cylinder axis AX3 is substantially parallel to the up-down direction (vertical direction). In this case, the gravity of the main body 10 acts on the electric therapy device 100A downward, that is, toward one side in the second direction (DR2 direction) perpendicular to the first direction (more specifically, toward one side in the direction parallel to the cylinder axis AX3).

[0075] In this case, as in the second embodiment, the electrode section 30 has a function of buffering stress and includes the first line 31 and the second line 32 extending substantially parallel to the direction in which the first end 13 of the main body section 10 extends. This makes it difficult for the electrode section 30 to come off, and therefore makes it difficult for the electric treatment device 100A to come off from the treatment site during treatment.

[0076] When removing the electrotherapeutic device 100B from the body surface, the main body portion 10 is grasped and moved in a direction away from the body surface.

[0077] Specifically, as shown by arrows AR1 and AR2 in the figure, a peeling force can be applied to each of both ends of the electrode portion 30 in the first direction (more specifically, the first line 31 and the second line 32) in a direction toward the inside in the circumferential direction of the tubular member 20.

[0078] In this manner, the entire electrotherapy device 100B can be easily removed from the body surface by a single action of moving the main body portion 10.

[0079] (First Modification) Fig. 5 is a schematic diagram of an electric treatment device according to a first modified example. An electric treatment device 100C according to the first modified example will be described with reference to Fig. 5.

[0080] 5, an electric treatment device 100C according to the first modification is different from an electric treatment device 100B according to the third embodiment in the shape of a second portion 22. The other configurations are substantially the same.

[0081] The first portion 21 has a constant length parallel to the cylinder axis AX3 of the cylindrical member 20 in the circumferential direction of the cylindrical member 20. The second portion 22 is provided to include a portion where the length parallel to the cylinder axis AX3 varies in the circumferential direction. The second portion 22 has a portion where the length parallel to the cylinder axis direction is shorter than that of the first portion 21. In the region where the second portion 22 overlaps with the main body 10, the length parallel to the cylinder axis AX3 direction of the second portion 22 is shorter than that of the first portion 21. More specifically, the length parallel to the cylinder axis AX3 direction of the second portion 22 becomes shorter from the boundary with the first portion 21 toward the main body 10.

[0082] Even when configured as described above, electric treatment device 100C according to the first modification has substantially the same effects as electric treatment device 100B according to embodiment 3. Furthermore, since second portion 22 has the above-described shape, the area of ​​cylindrical member 20 can be reduced, making electric treatment device 100C lighter and reducing its manufacturing cost.

[0083] The configuration of the cylindrical member 20 of the first modified example can also be applied to the first cylindrical member 210 and the second cylindrical member 220 of the second embodiment and the fourth embodiment described below.

[0084] (Embodiment 4) Fig. 6 is a schematic diagram of an electric treatment device according to embodiment 4. An electric treatment device 100D according to embodiment 4 will be described with reference to Fig. 6.

[0085] 6, an electric treatment device 100D according to the fourth embodiment differs from an electric treatment device 100A according to the second embodiment in that it includes a fixing member 50 and in the orientations of a first cylindrical member 210 and a second cylindrical member 220. The other configurations are substantially the same.

[0086] The fixing member 50 is a member to which the main body portion 10 is fixed. The fixing member 50 includes a first fixing portion 51 and a second fixing portion 52.

[0087] The first fixed portion 51 is fixed to the second portion 212 of the first cylindrical member 210. More specifically, the first fixed portion 51 is fixed to an outer surface 212a of the second portion 212. The first fixed portion 51 extends along the cylindrical axis AX1 direction. The first fixed portion 51 is provided, for example, so as to reach from one end to the other end of the second portion 212 in a direction parallel to the cylindrical axis AX1 direction.

[0088] The second fixed portion 52 is fixed to the second portion 222 of the second cylindrical member 220. More specifically, the second fixed portion 52 is fixed to an outer surface 222a of the second portion 222. The second fixed portion 52 extends along the cylindrical axis AX2 direction. The second fixed portion 52 is provided, for example, so as to reach from one end to the other end of the second portion 222 in a direction parallel to the cylindrical axis AX2 direction. The second fixed portion 52 is disposed substantially in the same straight line as the first fixed portion 51.

[0089] The first fixing portion 51 and the second fixing portion 52 are made of a resin material such as plastic, or a metal material. The first fixing portion 51 and the second fixing portion 52 may be provided in a rod shape or a flat shape.

[0090] In a plan view, the cylindrical axis AX1 of the first cylindrical member 210 and the cylindrical axis AX2 of the second cylindrical member 220 are parallel to an arrangement direction in which the first cylindrical member 210 and the second cylindrical member 220 are aligned. In addition, the cylindrical axis AX1 of the first cylindrical member 210 and the cylindrical axis AX2 of the second cylindrical member 220 are parallel to a first direction (DR1 direction) in which the first end 13 and the second end 14 of the main body 10 face each other.

[0091] In this case, on the first electrode portion 310 side, the first line 311 and the second line 312 are arranged side by side in the circumferential direction of the first cylindrical member 210. The third line 313 connects ends of the first line 311 and the second line 312 located closer to the main body portion 10 in the direction parallel to the cylindrical axis AX1. The fourth line 314 connects ends of the first line 311 and the second line 312 located farther from the main body portion 10 in the direction parallel to the cylindrical axis AX1.

[0092] Similarly, on the second electrode portion 320 side, the first line 321 and the second line 322 are arranged side by side in the circumferential direction of the second cylindrical member 220. The third line 323 connects ends of the first line 321 and the second line 322 located closer to the main body portion 10 in the direction parallel to the cylindrical axis AX2. The fourth line 324 connects ends of the first line 321 and the second line 322 located farther from the main body portion 10 in the direction parallel to the cylindrical axis AX2.

[0093] The third lines 313, 323 and the fourth lines 314, 324 are approximately parallel to the first end 13 and the second end 14 of the main body portion 10 when the first electrode portion 310 and the second electrode portion 320 are attached or when viewed in a planar view.

[0094] The main body 10 is fixed to the fixing member 50. Specifically, one end side of the main body 10 in the arrangement direction in which the first cylindrical member 210 and the second cylindrical member are aligned is fixed to the first fixing portion 51, and the other end side of the main body 10 in the arrangement direction is fixed to the second fixing portion 52. That is, the first end 13 of the main body 10 is fixed to the first fixing portion 51, and the second end 14 of the main body 10 is fixed to the second fixing portion 52. As a result, the main body 10 is fixed to the first cylindrical member 210 and the second cylindrical member 220 via the fixing member 50.

[0095] The electric therapy device 100D may be attached to the body surface so that the cylinder axes AX1 and AX2 are substantially parallel to the up-down direction (vertical direction). In this case, the gravity of the main body 10 acts on the electric therapy device 100A downward (to one side in the cylinder axis direction).

[0096] In the fourth embodiment, the first electrode section 310 and the second electrode section 320 also exhibit a function of buffering stress. In addition, the first line 311, the second line 312, and the first line 321, the second line 322 parallel to the cylindrical axis direction AX1, AX2 are stretched, so that the electric treatment device 100D is unlikely to come off in the DR1 direction, and the electric treatment device 100D is unlikely to come off from the treatment site during treatment.

[0097] When removing the electric treatment device 100D from the body surface, the main body 10 is grasped and moved in a direction away from the body surface. At this time, the fixing member 50 (more specifically, the first fixing part 51 and the second fixing part 52) ​​to which the main body 10 is fixed also moves, so that a peeling force can be applied to the first electrode part 310 and the second electrode part 320 at the same time.

[0098] Specifically, as shown by arrows AR1 and AR2 in the figure, a peeling force can be applied to each of both ends (more specifically, the first line 311 and the second line 312) of the first electrode portion 310 in the circumferential direction of the first tubular member 210, toward the inside of the circumferential direction of the first tubular member 210.

[0099] Furthermore, as shown by arrows AR3 and AR4 in the figure, a peeling force can be applied to each of both ends (more specifically, the first line 321 and the second line 322) of the second electrode portion 320 in the circumferential direction of the second tubular member 220, toward the inside in the circumferential direction of the second tubular member 220.

[0100] Furthermore, the first fixing portion 51 is arranged to reach from the one end to the other end of the first cylindrical member 210 in the direction of the cylindrical axis AX1, and the second fixing portion 52 is arranged to reach from the one end to the other end of the second cylindrical member 220 in the direction of the cylindrical axis AX2, so that a peeling force can be applied uniformly to the first electrode portion 310 and the second electrode portion 320.

[0101] In this manner, also in the fourth embodiment, the entire electrotherapy device 100D can be easily removed from the body surface by a single action of moving the main body portion 10.

[0102] In the above-mentioned second to fourth embodiments and the modified examples, the first electrode section 310, the second electrode section 320, and the electrode section 30 are shaped like rectangles, but the shape is not limited to this and may be any suitable shape such as a circle, an ellipse, a polygon, an oval, etc. Also, the line constituting the outer edge of the electrode section is not limited to a straight line and may be a zigzag or curved line.
