Description

[Technical Field]

[0001] The present disclosure relates to a finger electrode pad and a low-frequency treatment device including the same. [Background technology]

[0002] As a conventional electrode pad, Japanese Patent Application Laid-Open No. 2021-052868 (Patent Document 1) discloses a configuration in which a surface material, a conductive layer, and an adhesive gel layer are laminated. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2021-052868 Summary of the Invention [Problem to be solved by the invention]

[0004] When attaching electrode pads to areas with high curvature, such as the fingers, for electrical treatment, if no special measures are taken, the electrode pads will not conform to the surface of the hand and will easily peel off. Furthermore, if steam generated from the body surface cannot escape, the skin will become soggy and prone to rashes.

[0005] The present disclosure has been made in consideration of the above-mentioned problems, and the purpose of the present disclosure is to provide a finger electrode pad and a low-frequency treatment device that have high conformability to the surface of the finger and that allow steam to be easily released from the body surface. [Means for solving the problem]

[0006] A finger electrode pad according to the present disclosure includes a laminate including a strip-shaped electrode portion that can be attached to the back side of a finger, and an insulating layer laminated on the electrode portion. The laminate has a first end and a second end located at both ends in the width direction parallel to the width direction of the finger when the electrode portion is attached to the back side of the finger. In the attached state, the first end is located on the ulnar side of the finger, and the second end is located on the radial side of the finger. Each of the portions of the laminate located on the first end side and the second end side is provided with a deformation promoting portion that promotes deformation of the laminate so that the laminate conforms to the surface of the finger in the circumferential direction. A first slit is provided between the deformation promoting portion located on the first end side and the deformation promoting portion located on the second end side in the width direction of the laminate, penetrating at least the insulating layer at positions corresponding to the first and second joints of the finger.

[0007] According to the above configuration, the first end and the second end of the laminate are provided with deformation promoting portions, so that the laminate can be attached to the back side of the finger so as to conform to the surface of the finger in the circumferential direction. Furthermore, the first slits are provided at positions corresponding to the first and second joints of the finger, so that the electrode pads can remain attached to the body surface of the finger even when the joints are bent. Furthermore, the first slits allow steam generated from the body surface to be released to the outside through the first slits.

[0008] In the finger electrode pad according to the present disclosure, the deformation promoting portion may be constituted by a notch provided at a position corresponding to the first joint and the second joint of the finger when the electrode pad is attached.

[0009] When the electrode pad is attached to the back side of the finger, when the first joint and the second joint are bent, the movement at the positions corresponding to the first joint and the second joint of the finger becomes large. As in the above configuration, by providing the notch as a deformation promoting portion at the position where the movement becomes large, the deformation of the laminate is promoted so as to correspond to the change in the movement, and it is possible to prevent the electrode pad from peeling off from the surface of the finger.

[0010] In the finger electrode pad according to the present disclosure, the first slit may be provided so as to extend from a first joint to a second joint of the finger in the attached state.

[0011] According to the above configuration, the area of ​​the first slit can be made larger, which allows the electrode pad to conform more easily to the surface of the hand, and also allows steam to be released more effectively.

[0012] In the finger electrode pad according to the present disclosure, the deformation promoting portion may be configured by a second slit extending along the extending direction of the finger in the attached state.

[0013] According to the above configuration, the second slits, which are deformation promoting portions, extend along the direction of extension of the finger, thereby promoting deformation of the laminate over a wide area and preventing the electrode pad from peeling off from the surface of the finger. In addition, steam can be released to the outside from the second slits.

[0014] In the finger electrode pad based on the present disclosure, the second slit may be provided on the first end side, the second slit may be provided on the second end side, and a third slit may be provided connecting the first slit.

[0015] According to the above configuration, the third slit is provided so as to straddle the first slit and the second slit, which makes it easier for the laminate to deform in the vicinity of the first slit, the second slit, and the third slit, thereby allowing the electrode pad to conform more closely to the surface of the finger.

[0016] In the finger electrode pad according to the present disclosure, the width of the first slit in the width direction of the laminate may be larger than the width of the second slit.

[0017] According to the above configuration, by increasing the width of the first slit, it is possible to improve the ability of the laminated body to follow the body surface that moves significantly when the first joint and the second joint are bent.

[0018] In the finger electrode pad according to the present disclosure, the first slit may include a plurality of slits arranged side by side along the width direction.

[0019] According to the above configuration, by configuring the first slit with a plurality of slits, it is possible to improve the ability of the laminated body to follow the body surface which moves significantly when the first joint and the second joint are bent.

[0020] In the finger electrode pad according to the present disclosure, the first slit may penetrate the insulating layer and the electrode portion.

[0021] According to the above configuration, the air can be emitted directly from the back surface of the finger exposed through the first slit. In addition, since the first slit penetrates the insulating layer and the electrode portion, the conformability of the laminate can be improved.

[0022] A low-frequency therapy device according to the present disclosure comprises the finger electrode pad and a main body including a control unit that controls the current flowing through the electrode unit. [Effects of the Invention]

[0023] According to the present disclosure, it is possible to provide a finger electrode pad that has high conformability to the surface of a finger and that allows steam to be easily released from the body surface. [Brief explanation of the drawings]

[0025] 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 numerals in the drawings, and the description thereof will not be repeated.

[0026] (Embodiment 1) Fig. 1 is a schematic diagram of a low-frequency treatment device according to embodiment 1. Fig. 2 is a schematic cross-sectional view taken along line II-II shown in Fig. 1. The low-frequency treatment device 100 according to embodiment 1 will be described with reference to Figs. 1 and 2.

[0027] As shown in FIG. 1, the low-frequency therapy device 100 includes a finger electrode pad 1 and a main body 50. The main body 50 includes a housing 51 and a control unit 52. The control unit 52 is housed in the housing 51. The control unit 52 controls the current and voltage flowing through the electrode unit 11 of the finger electrode pad 1, which will be described later. The control unit 52 is electrically connected to the electrode unit 11. An electrical path 53 is formed, for example, of wiring. The tip of the electrical path 53 is connected to a connector 15 that is electrically connected to the electrode unit 11.

[0028] The finger electrode pad 1 is attached so as to fit along the surface of the finger from the back side of the finger, which is located opposite the pad of the finger. When the finger electrode pad 1 is attached to the surface of the finger, a current is supplied to the finger electrode pad 1, thereby alleviating pain in the finger.

[0029] As shown in FIGS. 1 and 2, the finger electrode pad 1 according to the first embodiment includes a laminate 10 including an electrode portion 11 and an insulating layer 12. As shown in FIG.

[0030] The laminate 10 has a band-like shape extending along a length direction L. The length direction L is parallel to the direction in which the finger extends when the laminate is attached. The laminate 10 has a first end 10a and a second end 10b on either side of a width direction W that is perpendicular to the length direction L. The first end 10a is located on one side of the width direction W, and the second end 10b is located on the other side of the width direction W. The width direction W is parallel to the width direction of the finger when the laminate is attached.

[0031] The electrode unit 11 is provided in a strip shape and configured to be attached to the back side of the finger. The electrode unit 11 may be, for example, a gel pad, or may be a laminate of an adhesive layer and a conductive layer. When the adhesive layer and the conductive layer are laminated, the adhesive layer is located on the opposite side of the electrode from the side on which the insulating layer 12 is located. For example, metals such as aluminum, copper, nickel, or carbon can be used as the conductive layer. The electrode unit 11 is flexible and is provided so as to be deformable to fit the shape of the finger.

[0032] The insulating layer 12 is laminated on the electrode portion 11. The insulating layer 12 is provided so as to cover the electrode portion 11. The insulating layer 12 may be made of, for example, fabric, nonwoven fabric, or the like. The insulating layer 12 is flexible and is provided so as to be deformable so as to fit the shape of the finger.

[0033] The laminate 10 has deformation promoting portions 20 provided at each of the portions located on the first end 10a side and the second end 10b side. As will be described later, the deformation promoting portions 20 promote deformation of the laminate 10 so that the laminate 10 conforms to the surface of the finger in the circumferential direction when the finger electrode pad 1 is attached to the finger. In this embodiment, the deformation promoting portions 20 include a pair of first cutouts 21 and a pair of second cutouts 22. The pair of first cutouts 21 are located on one side of the pair of second cutouts 22 in the length direction L. The pair of first cutouts 21 are provided at positions corresponding to first joints of the finger. The pair of second cutouts 22 are provided at positions corresponding to second joints of the finger.

[0034] In the width direction W of the laminate 10, first slits 31A, 31B are provided between the deformation promoting portion 20 provided on the first end 10a side and the deformation promoting portion 20 provided on the second end 10b side, at positions corresponding to the first joint of the finger and the second joint of the finger.

[0035] The first slit 31A is provided between the pair of first cutouts 21 in the width direction W. The first slit 31A includes a plurality of slits 32 aligned along the length direction L. The plurality of slits 32 penetrate the insulating layer 12 and the electrode portion 11.

[0036] The first slit 31B is provided between the pair of second cutouts 22 in the width direction W. The first slit 31B includes a plurality of slits 32 aligned along the length direction L. The plurality of slits 32 penetrate the insulating layer 12 and the electrode portion 11.

[0037] Fig. 3 is a schematic cross-sectional view of a finger electrode pad according to a modified example. As shown in the modified example of Fig. 3, the plurality of slits 32 may penetrate the insulating layer 12 without penetrating the electrode portion 11. That is, it is sufficient that the first slits 31A and 31B penetrate at least the insulating layer 12.

[0038] Specifically, when electrode unit 11 is composed of an adhesive layer and a conductive layer, and the adhesive layer is made of a stretchy gel that does not contain paper, nonwoven fabric, or the like, first slits 31A, 31B preferably penetrate insulating layer 12 and the conductive layer without penetrating electrode unit 11. In this case, the adhesive layer is easily deformed and conforms to the surface of the finger even without providing slits in the adhesive layer.

[0039] On the other hand, for example, when the adhesive layer is made of a gel containing paper, nonwoven fabric, or the like, it is preferable that the first slits 31A, 31B penetrate the electrode portion 11 as in embodiment 1. In this case, even if the adhesive layer is difficult to deform, the conformability of the laminate 10 can be improved.

[0040] FIG. 4 is a schematic diagram showing a first step when attaching the finger electrode pad according to the first embodiment to the back of the finger.

[0041] When attaching the finger electrode pad 1 to the back side of the finger, first, the finger electrode pad 1 is placed on the back side of the finger so that the first slit 31A overlaps the first joint and the first slit 31B overlaps the second joint, as shown in Fig. 4. In this state, the first end 10a and the second end 10b protrude outward beyond the ulnar surface 5c and the radial surface 5d of the finger in a planar view.

[0042] Fig. 5 is a schematic diagram showing a second step in attaching the finger electrode pad according to embodiment 1 to the back of the finger. Fig. 6 is a schematic perspective view showing the attached state of the finger electrode pad according to embodiment 1. For convenience, main body 50, electrical path 53, and connector 15 are omitted from Figs. 4 to 6 above.

[0043] Next, as shown in Fig. 5, the portion of the finger electrode pad 1 that protrudes outward in the width direction W from the back of the finger is wrapped around the ulnar side 5c and radial side 5d of the finger. As a result, as shown in Fig. 6, the finger electrode pad 1 is attached to the finger so as to conform to the surface of the finger in the circumferential direction. At this time, the deformation promoting portions 20 are provided at each of the first end 10a and the second end 10b of the laminate 10, which promote deformation of the laminate 10 so as to conform to the surface of the finger in the circumferential direction. As a result, the finger electrode pad 1 can be made to conform to a surface with a high degree of curvature, such as a finger.

[0044] In this embodiment, the finger electrode pad 1 is attached to the middle finger, and in this attached state, the first end 10a of the laminate 10 is located on the ulnar side 5c of the finger, and the second end 10b is located on the radial side 5d of the finger. The finger to which the finger electrode pad 1 is attached is not limited to the middle finger, and can be selected appropriately depending on the area to be treated.

[0045] Furthermore, the laminate 10 is easily bent by providing the first slits 31A and 31B. The first slits 31A and 31B are located at positions corresponding to the first and second joints of the finger, so that the laminate 10 can be bent in response to bending of each joint. This allows the finger electrode pad 1 to remain attached to the surface of the finger even when the joint is bent.

[0046] In particular, when the electrode pad is attached from the back side of the finger, when the first joint and the second joint are bent, the movement at the positions corresponding to the first joint and the second joint of the finger becomes large. By providing a pair of first notches 21 and a pair of second notches 22 as the deformation promoting portions 20 at such positions, the deformation of the laminate 10 is promoted so as to correspond to the change in the movement, and this also makes it possible to prevent the finger electrode pad 1 from peeling off from the surface of the finger.

[0047] In addition, since the first slits 31A and 31B are provided, even if steam is generated from the body surface, the steam can be released to the outside through the first slits 31A and 31B.

[0048] (Embodiment 2) Fig. 7 is a schematic plan view showing a state before attachment of a finger electrode pad according to embodiment 2. A finger electrode pad 1A according to embodiment 2 will be described with reference to Fig. 7. For convenience, the main body 50, the electrical path 53, and the connector 15 are also omitted from Fig. 7.

[0049] 7, the finger electrode pad 1A according to the second embodiment differs from the finger electrode pad 1 according to the first embodiment in that the configuration of the deformation promoting portion 20 and the shape of the first slit 31 are different, and that a third slit 34 is provided. The other configurations are almost the same.

[0050] The first slit 31 is provided so as to extend from the first joint to the second joint of the finger when the sheet is attached. The first slit 31 extends along the length direction L. More specifically, the first slit 31 extends along the direction in which the finger extends when the sheet is attached. The first slit 31 is provided in approximately the center of the laminate 10 in the width direction W. In this embodiment, a single first slit 31 is provided.

[0051] The deformation promoting portion 20 is configured by a pair of second slits 33. Each second slit 33 extends along the length direction L. The pair of second slits 33 are spaced apart in the width direction W. One of the pair of second slits 33 is located on the first end portion 10a side. The other of the pair of second slits 33 is located on the second end portion 10b side. A first slit 31 is located between the pair of second slits 33. For example, in the width direction W, the width of the pair of second slits 33 and the width of the first slit 31 are approximately equal.

[0052] The third slit 34 is provided to connect the pair of second slits 33 and the first slit 31. The third slit 34 extends in a direction intersecting the extending direction of the first slit 31 and the pair of second slits 33. More specifically, the third slit 34 extends along the width direction.

[0053] Even when configured as described above, the finger electrode pad 1A according to the second embodiment can achieve substantially the same effects as those of the first embodiment.

[0054] In addition, since the first slit 31 is provided from the first joint to the second joint when the finger electrode pad 1A is attached, the area of ​​the first slit can be made larger, which makes it easier for the finger electrode pad 1A to conform to the surface of the hand and allows steam to be released more effectively.

[0055] Furthermore, since the second slits, which are deformation promoting portions, extend along the direction of extension of the finger, deformation of the laminate 10 is promoted over a wide area, and peeling of the finger electrode pad 1A from the surface of the finger can be suppressed. Also, steam can be released to the outside from the second slits 33.

[0056] In addition, by providing the third slit 34 so as to straddle the first slit 31 and the pair of second slits 33, the laminate 10 becomes more easily deformable in the vicinity of the first slit 31, the second slit 33, and the third slit 34. This allows the electrode pad to conform more closely to the surface of the finger.

[0057] (Embodiment 3) Fig. 8 is a schematic plan view showing a state before attachment of a finger electrode pad according to embodiment 3. A finger electrode pad 1B according to embodiment 3 will be described with reference to Fig. 8. For convenience, the main body 50, the electrical path 53, and the connector 15 are also omitted from Fig. 8.

[0058] 8, the finger electrode pad 1B according to the third embodiment differs from the finger electrode pad 1 according to the first embodiment in the configuration of the deformation promoting portion 20 and the shape of the first slit 31. The other configurations are almost the same.

[0059] The first slit 31 is provided so as to extend from the first joint to the second joint of the finger when the sheet is attached. The first slit 31 extends along the length direction L. More specifically, the first slit 31 extends along the direction in which the finger extends when the sheet is attached. The first slit 31 is provided in approximately the center of the laminate 10 in the width direction W. In this embodiment, a single first slit 31 is provided.

[0060] The deformation promoting portion 20 is configured by a pair of second slits 33. Each second slit 33 extends along the length direction L. The pair of second slits 33 are arranged spaced apart in the width direction W. One of the pair of second slits 33 is arranged on the first end portion 10a side. The other of the pair of second slits 33 is arranged on the second end portion 10b side. The first slit 31 is arranged between the pair of second slits 33.

[0061] In this embodiment, the width of the first slit 31 in the width direction W is greater than the width of the pair of second slits 33.

[0062] Even when configured as described above, the finger electrode pad 1B according to the third embodiment can achieve substantially the same effects as those of the first embodiment.

[0063] In addition, since the first slit 31 is provided from the first joint to the second joint when the finger electrode pad 1A is attached, the area of ​​the first slit can be made larger. This allows the finger electrode pad 1A to more easily conform to the surface of the hand and to more effectively release steam. The width of the first slit 31 in the width direction W is larger than the width of the pair of second slits 33, so that the above-mentioned effect can be more effectively exhibited.

[0064] Furthermore, since the second slits, which are deformation promoting portions, extend along the direction of extension of the finger, deformation of the laminate 10 is promoted over a wide area, and peeling of the finger electrode pad 1A from the surface of the finger can be suppressed. Also, steam can be released to the outside from the second slits 33.

[0065] (Fourth embodiment) Fig. 9 is a schematic plan view showing a state before attachment of a finger electrode pad according to embodiment 4. A finger electrode pad 1C according to embodiment 4 will be described with reference to Fig. 9. For convenience, the main body 50, the electrical path 53, and the connector 15 are also omitted from Fig. 9.

[0066] 9, the finger electrode pad 1C according to the fourth embodiment differs from the finger electrode pad 1B according to the third embodiment in the shape of the first slit 31. The other configurations are almost the same.

[0067] The first slit 31 includes a plurality of slits 35 arranged side by side along the width direction W.

[0068] Even when configured as described above, the finger electrode pad 1C according to embodiment 4 can achieve substantially the same effects as the finger electrode pad 1B according to embodiment 3. By configuring the first slits 31 with a plurality of slits 35, it is possible to improve the ability of the laminated body 10 to follow the body surface that moves significantly when the first joint and the second joint are bent.

[0069] (Other variations) The finger electrode pads according to the above-described modifications and embodiments 2 to 4 can be used in low-frequency therapy device 1 in place of the finger electrode pad according to embodiment 1. Furthermore, the slits according to embodiments 2 to 4 may be provided so as to penetrate insulating layer 12 and electrode section 11 in accordance with the configuration of electrode section 11, as in embodiment 1, or may penetrate insulating layer 12 and the conductive layer that constitutes part of the electrode section without penetrating electrode section 11.
