[0005] Patent Document 1: Japanese Patent Application Publication No. 2012-72262 Summary of the Invention

[0006] The problem that the invention aims to solve

[0007] Electrotherapy devices, such as low-frequency therapy devices, relieve muscle tension and pain by attaching adhesive electrodes to the user's affected area and applying low-frequency electrical stimulation. However, the adhesive strength of the electrodes to the human body deteriorates with repeated use due to dirt and sweat. Users are often unaware of the electrodes' lifespan or worry that prolonged use beyond their original specifications will prevent them from fully utilizing their original performance.

[0008] Recently, a wireless low-frequency therapeutic device and electrode that can be used outdoors has also been developed. Since it is unavoidable to use the device in environments where the electrode is prone to degradation, the necessity for users to identify the degradation status of the electrode has been further increased.

[0009] However, when using the evaluation method described in Patent Document 1, a constant temperature bath is required to maintain the high temperature and high humidity environment for a specified time. In daily life, it is difficult for users to easily confirm the deterioration state of the electrodes (specifically, the adhesion of the electrodes).

[0010] This disclosure was made in view of the above-mentioned problems, and the object of this disclosure is to provide an adhesive force verification device that can simply construct and verify the adhesive force of the electrode.

[0011] Solution for solving the problem

[0012] The adhesive force verification device disclosed herein is a device for verifying the adhesive force of electrodes used in an electrotherapy device. This adhesive force verification device includes an adhesive portion capable of adhering to the adhesive portion of the electrode. The adhesive portion includes a reference surface and an active surface connected to the reference surface. The active surface is configured such that, when the adhesive portion is already adhered, the side of the active surface farther from the reference surface is more prone to peeling off the adhesive portion compared to the side of the active surface closer to the reference surface.

[0013] In the adhesive force verification device based on the present disclosure, when the direction perpendicular to the reference surface is set as the height direction, the end of the working surface located on the side far from the reference surface is located at a lower position than the end of the working surface located on the side close to the reference surface.

[0014] In the adhesive force verification device based on the present disclosure, the working surface may have a curved portion that bends toward a lower position as it moves away from the reference surface.

[0015] In the adhesive force verification device based on the present disclosure, the bending portion may be configured such that its radius of curvature decreases as it moves away from the reference surface.

[0016] In the adhesive force verification device based on the present disclosure, the working surface may include a stepped portion that tends to be lower as it moves from the side closer to the reference surface to the side farther from the reference surface.

[0017] The adhesive force verification device based on this disclosure may further include a verification unit capable of verifying the amount of peeling off the electrode.

[0018] In the adhesive strength verification device based on the present disclosure, the verification part may include: a light-transmitting part that can visually verify at least the portion of the electrode that has peeled off from the adhesive part; and a scale that indicates the amount of peeling off from the adhesive part in stages.

[0019] In the adhesive force verification device based on the present disclosure, the verification unit may include a sensor capable of sensing the amount of peeling.

[0020] In the adhesive force verification device based on the present disclosure, a portion of the electrotherapy device may be configured to be fixed.

[0021] Invention Effects

[0022] According to this disclosure, an adhesive force verification device can be provided that can simply construct and verify the adhesive force of the electrodes. Attached Figure Description

[0035] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. It should be noted that in the embodiments shown below, the same or common parts are labeled with the same reference numerals in the drawings, and their description will not be repeated.

[0036] (Implementation Method 1)

[0037] Figure 1This is a perspective view showing the case where an electrotherapy device is provided in the adhesive force verification device of Embodiment 1. Figure 2 This is a perspective view showing the state in which the adhesive force verification device of Embodiment 1 is equipped with an electrotherapy device.

[0038] The adhesion confirmation device 50 in Embodiment 1 is used to confirm the adhesion of the two electrodes 20 and 30 used in the electrotherapy device 1 (see reference). Figure 3 (A device for bonding force.)

[0039] Electrotherapy device 1 has a main body 10, electrodes 20 and 30 (see reference). Figure 3 The electrotherapy device 1 is, for example, a low-frequency therapeutic device that relieves pain by supplying low-frequency pulsed current to electrodes 20 and 30 that are in contact with the user's body surface. The frequency of the low-frequency pulsed current is, for example, 1 Hz or higher and 1200 Hz or lower.

[0040] The main body 10 includes a housing 11 and an operating unit 15. A circuit section (not shown) is housed inside the housing 11. The circuit section is electrically connected to the electrodes 20 and 30 via an electrical path, controlling the current and voltage flowing to the electrodes 20 and 30.

[0041] An operation unit 15 is provided in the housing 11. The operation unit 15 may include, for example, a switch for measuring. The operation unit 15 is not limited to a push-button switch; for example, it may be a pressure-sensitive (resistive) or proximity (capacitive) touch panel switch. In addition, a display unit may be provided separately from the operation unit 15 in the housing 11.

[0042] Electrodes 20 and 30 are arranged spaced apart in a first direction such that, in a top view, the main body 10 is located between the electrodes 20 and 30. Electrode 20 is disposed on one side of the main body 10 in the first direction. Electrode 30 is disposed on the other side of the main body 10 in the first direction.

[0043] Electrodes 20 and 30 are portions used to conduct current to the user. Electrodes 20 and 30 are configured to adhere to the user's body surface using adhesive force. Electrodes 20 and 30 have adhesive portions. Electrodes 20 and 30 can be, for example, gel pads, or components formed by laminating adhesive layers and conductive members. When electrodes 20 and 30 are in contact with the user's body surface, current is supplied to electrodes 20 and 30, thereby allowing current to flow to the user.

[0044] The retaining part 40 holds electrodes 20 and 30. The retaining part 40 is flexible, for example, and is configured to deform along the surface of the body. As the retaining part 40, for example, an insulating fabric can be used.

[0045] The retaining part 40 and the electrodes 20 and 30 are flexible, and the restoring force is exerted when deformed to restore the original shape. Thus, as will be described later, when the adhesive force confirming device 50 is attached to the electrodes 20 and 30, the peeling force can be effectively applied to the electrodes 20 and 30 (more specifically to the adhesive part mentioned above).

[0046] The retaining part 40 is fixed to the main body part 10, for example. The retaining part 40 has a first retaining part 41 and a second retaining part 42. The first retaining part 41 holds the electrode 20. The shape of the first retaining part 41 is approximately the same as the shape of the electrode 20. The second retaining part 42 holds the electrode 30. The shape of the second retaining part 42 is approximately the same as the shape of the electrode 30. The first retaining part 41 and the second retaining part 42 can be connected by a connecting part.

[0047] The adhesion testing device 50 has an adhesive portion 60 capable of adhering to two electrodes 20 and 30 (more specifically, the adhesive portion described above). In Embodiment 1, the adhesion testing device 50 has a block shape, with the adhesive portion 60 formed by the upper surface of this block shape. The adhesion testing device 50 is, for example, made of a resin component. There are no particular limitations on the raw materials, surface roughness, or surface microstructure of the adhesion testing device 50, as long as the adhesive portion can adhere to the electrodes 20 and 30.

[0048] The adhesive part 60 has two working surfaces 61 and 62 and a reference surface 63. The reference surface 63 is, for example, set to be flat. The reference surface 63 may be parallel to the horizontal direction, for example, but its orientation may be appropriately changed when measuring the adhesive force.

[0049] The action surfaces 61 and 62 are connected to the reference surface 63. The action surfaces 61 and 62 are configured such that, in a top view, the reference surface 63 is located between the action surfaces 61 and 62. The action surfaces 61, 63, and 62 are arranged sequentially in a first direction. The action surface 61 is positioned on one side of the first direction relative to the reference surface 63. The action surface 62 is positioned on the other side of the first direction relative to the reference surface 63.

[0050] The working surfaces 61 and 62 are configured such that, in the pasted state where the electrodes 20 and 30 have been pasted, the side of the working surfaces 61 and 62 that is farther from the reference surface 63 is easier to peel off the adhesive portion of the electrodes 20 and 30 compared to the side of the working surfaces 61 and 62 that is closer to the reference surface 63.

[0051] Specifically, when the direction perpendicular to the reference plane 63 is defined as the height direction, the end of each of the acting surfaces 61 and 62 located further from the reference plane 63 is positioned lower than the end of each of the acting surfaces 61 and 62 located closer to the reference plane 63. It should be noted that when the reference plane 63 is parallel to the horizontal direction, the height direction is parallel to the vertical direction.

[0052] More specifically, when the direction perpendicular to the reference plane 63 is set as the height direction, the working surfaces 61 and 62 have bends that curve toward a lower position as they move away from the reference plane 63. The radius of curvature of these bends is configured to decrease as they move away from the reference plane 63.

[0053] The active surfaces 61, 62 and the reference surface 63 are composed of a composition similar to that of the body surface. For example, the active surfaces 61, 62 and the reference surface 63 have a surface roughness approximately the same as that of the body surface. This allows for appropriate evaluation of the adhesion of the electrodes 20, 30 to the body surface. The active surfaces 61, 62 and the reference surface 63 may also be composed of artificial skin.

[0054] When the electrotherapy device 1 is arranged in the adhesion force confirmation device 50, with the main body 10 facing the reference surface 63 and the electrodes 20 and 30 facing the action surfaces 61 and 62, the electrotherapy device 1 is brought close to the adhesion force confirmation device 50 from above, and the main body 10 is placed on the reference surface 63.

[0055] Figure 3 This is a front view showing the state in which the adhesion verification device of Embodiment 1 is equipped with an electrotherapy device.

[0056] like Figure 3 As shown, with the main body 10 placed on the reference surface 63, the electrodes 20 and 30 are separated from the adhesive portion 60. From this state onwards, the electrodes 20 and 30 are adhered to the working surfaces 61 and 62.

[0057] Figure 4 This is a front view showing the adhesive state in which electrodes are attached to the working surface of the adhesive force verification device in Embodiment 1.

[0058] The electrode 20 has a top portion located on the side furthest from the main body 10 in a first direction and a root portion located on the side closer to the main body 10. The top portion of the electrode 20 is attached to the working surface 61. The root portion of the electrode 20 can be attached to the reference surface 63.

[0059] The electrode 30 has a top portion located on the side furthest from the main body 10 in a first direction and a root portion located on the side closer to the main body 10. The top portion of the electrode 30 is attached to the working surface 62. The root portion of the electrode 30 can be attached to the reference surface 63.

[0060] In the aforementioned adhesive state, a peeling force is applied to the tips of electrodes 20 and 30 to return... Figure 3The state shown indicates that a peeling force is applied to the tips of electrodes 20 and 30, causing the retaining portion 40 to separate from the working surfaces 61 and 62. If the adhesive force of electrodes 20 and 30 (more specifically, the adhesive portion) weakens due to prolonged use, electrodes 20 and 30 separate from the working surfaces 61 and 62 based on the adhesive force. By visually inspecting this separation state, the user can confirm the adhesive force of electrodes 20 and 30.

[0061] The aforementioned peeling force is applied, for example, by the elastic recovery of the electrode pads including electrodes 20, 30 and the holding portion 40. Even if the elasticity of the electrode pad weakens or the initial adhesive force of the adhesive portion is strong, but the adhesive force weakens due to long-term use, and the peeling amount of electrodes 20, 30 is small, stress can be applied in the direction opposite to the adhesive force. Specifically, the reference surface 63 can be oriented downwards or slightly laterally, so that gravity acts on electrodes 20, 30. Furthermore, elastic members that generate stress resisting the adhesive force can be provided on the working surfaces 61, 62. These elastic members are provided on the working surfaces 61, 62 such that they face the top end side of electrodes 20, 30 in the aforementioned bonded state. When elastic members are provided on the working surfaces 61, 62, the working surfaces 61, 62 and the reference surface 63 can be flat and located on the same plane. Furthermore, the aforementioned elastic members can be provided even when electrodes 20, 30 and the holding portion 40 are not flexible.

[0062] As described above, in the adhesion strength verification device 50 of this embodiment, electrodes 20 and 30 are attached to the working surfaces 61 and 62, and the lifting state of electrodes 20 and 30 is visually verified, thereby verifying the adhesion strength of electrodes 20 and 30. As a result, the adhesion strength of electrodes 20 and 30 can be verified with a simple configuration.

[0063] It should be noted that, in the above example, the case in which the main body 10 is placed on the reference surface 63 and the electrodes 20 and 30 are attached to the working surfaces 61 and 62 is illustrated and explained. However, it is also possible to attach the electrodes 20 and 30 to the working surfaces 61 and 62 at the same time as placing the main body 10 on the reference surface 63.

[0064] (Implementation Method 2)

[0065] Figure 5 This is a perspective view showing the state in which the adhesive strength verification device of Embodiment 2 is equipped with an electrotherapy device. (See reference...) Figure 5 The adhesive force verification device 50A of Embodiment 2 will be described.

[0066] like Figure 5 As shown, when comparing the adhesion force verification device 50A of Embodiment 2 with the adhesion force verification device 50 of Embodiment 1, the main difference is that it has a verification section 70 that can verify the amount of electrode peeling. The other components are roughly the same.

[0067] The adhesion strength verification device 50A has a main body 51 and a plurality of wall portions 52 to 55. The main body 51 has a block shape and has a shape substantially the same as that of the adhesion strength verification device 50 of Embodiment 1. The plurality of wall portions 52 to 55 are configured to surround the main body 51. The plurality of wall portions 52 to 55 are configured to protrude upward beyond the adhesive portion 60.

[0068] The wall portions 54 and 55 are positioned opposite each other in a first direction. The wall portion 54 is located at the end of the main body portion 51 on one side of the first direction. The wall portion 55 is located at the end of the main body portion 51 on the other side of the first direction.

[0069] The wall portions 52 and 53 are positioned opposite each other in a second direction orthogonal to the first direction. Wall portion 52 is located at the end of the main body portion 51 on one side of the second direction. Wall portion 53 is located at the end of the main body portion 51 on the other side of the second direction. The second direction is also orthogonal to the vertical direction. It should be noted that the vertical direction is parallel to the direction in which the adhesion force confirming device 50A and the electrotherapy device 1 are arranged when the adhesion force confirming device 50A is equipped with the electrotherapy device 1. Furthermore, when the reference plane 63 is parallel to the horizontal direction, the vertical direction is the direction perpendicular to the reference plane 63. A confirming part 70 is provided in the wall portion 52.

[0070] Figure 6 This is a diagram showing the confirmation section for confirming the amount of electrode peeling in the adhesion confirmation device of Embodiment 2.

[0071] The confirmation section 70 includes a light-transmitting section 71 and a scale 72. The light-transmitting section 71 is configured to allow visual confirmation of the top end of the electrode 30. For example, an acrylic plate can be used as the light-transmitting section 71. The scale 72 is located next to the light-transmitting section 71 and indicates the amount by which the top end separates from the working surface 62. It should be noted that the scale 72 can also be located on the light-transmitting section 71.

[0072] Generally, the adhesive force of electrode 30 weakens over time as the number of uses increases or the duration of use increases. Depending on the strength of the adhesive force, the position of the graduation indicated by the tip of electrode 30 changes. When maintaining a strong adhesive force, the tip of electrode 30 is at the bottom. As the adhesive force weakens, the tip of electrode 30 indicates a graduation located further up. Thus, the amount of electrode 30 peeling can be confirmed via graduation 72. It should be noted that the example described above shows a graduation orientation perpendicular to the reference surface 63, but this is not a limitation; it can also be parallel to the reference surface 63.

[0073] Even with the configuration described above, the adhesion strength verification device 50A of Embodiment 2 achieves approximately the same effect as Embodiment 1. By providing the verification unit 70, the current adhesion strength can be verified more accurately.

[0074] (Implementation Method 3)

[0075] Figure 7 This is a front view showing the state in which the adhesion strength verification device of Embodiment 3 is equipped with an electrotherapy device. (Refer to...) Figure 7 The adhesive force verification device 50B of Embodiment 3 will be described.

[0076] like Figure 7 As shown, when comparing the adhesion force verification device 50B of Embodiment 3 with the adhesion force verification device 50 of Embodiment 1, the main difference is that it has a verification section 70B that can verify the amount of electrode peeling. The other components are roughly the same.

[0077] The confirmation unit 70B includes a first unit 73 for measuring the amount of peeling off electrode 20 and a second unit 74 for measuring the amount of peeling off electrode 30. The first unit 73 and the second unit 74 have multiple distance sensors 75. The multiple distance sensors 75 are arranged, for example, in a first direction. The multiple distance sensors 75 are configured to be located below electrodes 20 and 30 when they are already attached. The multiple distance sensors 75 are, for example, embedded in the main body 51.

[0078] The multiple distance sensors 75 are each configured to measure the distance from the distance sensor 75 to the electrode 30 in the vertical direction. For example, ultrasonic sensors capable of detecting the distance to an object in a non-contact manner can also be used as the multiple distance sensors 75.

[0079] As the adhesive force weakens, the distance from the distance sensor 75 to the electrode 30 increases. By measuring this distance, the amount of peeling off the electrode 30 can be determined.

[0080] Even with the configuration described above, the adhesion strength verification device 50B of Embodiment 3 achieves approximately the same effect as Embodiment 1. By providing the verification unit 70B, the current adhesion strength can be verified more accurately.

[0081] (Implementation Method 4)

[0082] Figure 8 This is a front view showing the state in which the adhesion strength verification device of Embodiment 4 is equipped with an electrotherapy device. (Refer to...) Figure 8 The adhesive force verification device 50C of Embodiment 4 will be described.

[0083] like Figure 8As shown, when comparing the adhesion force verification device 50C of Embodiment 4 with the adhesion force verification device 50 of Embodiment 1, the main difference is that it has a verification section 70C that can verify the amount of electrode peeling. The other components are roughly the same.

[0084] The verification unit 70C includes a first unit 73 for measuring the amount of peeling off electrode 20 and a second unit 74 for measuring the amount of peeling off electrode 30. The first unit 73 and the second unit 74 have multiple distance sensors 75. The multiple distance sensors 75 are, for example, arranged in a first direction. The multiple distance sensors 75 are configured to be located below electrodes 20 and 30 when they are already attached. The multiple distance sensors 75 may also be provided, for example, on the working surfaces 61 and 62.

[0085] Multiple distance sensors 75, such as contact-type electrode sensors, can measure the impedance (resistance value), capacitance, etc. of electrodes 20 and 30. By measuring the impedance, etc., which changes according to the contact state of electrodes 20 and 30, the amount of peeling off electrodes 20 and 30 can be determined.

[0086] Even with the configuration described above, the adhesion strength verification device 50C of Embodiment 4 achieves approximately the same effect as that of Embodiment 1. By providing the verification unit 70C, the current adhesion strength can be verified more accurately.

[0087] (Implementation Method 5)

[0088] Figure 9 This is a perspective view showing the adhesive force verification device of Embodiment 5. (Refer to...) Figure 9 The adhesive force verification device 50D of Embodiment 5 will be described.

[0089] like Figure 9 As shown, when comparing the adhesive force verification device 50D of Embodiment 5 with the adhesive force verification device 50 of Embodiment 1, the shape of the adhesive part 60D is different. Other components are largely the same.

[0090] In the adhesive part 60D, the active surface 61, the reference surface 63, and the active surface 62 are arranged sequentially in the second direction. The active surface 61 is disposed on one side of the second direction relative to the reference surface 63. The active surface 62 is disposed on the other side of the second direction relative to the reference surface 63.

[0091] In this case, the end of electrode 20 or 30 located on one side of the second direction is attached to the working surface 61, and the end of electrode 20 or 30 located on the other side of the second direction is attached to the working surface 62.

[0092] Even in the case configured as described above, the adhesive force verification device 50D of Embodiment 5 can achieve approximately the same effect as Embodiment 1.

[0093] (Implementation Method 6)

[0094] Figure 10 This is a perspective view showing the adhesive force verification device according to Embodiment 6. (Refer to...) Figure 10 The adhesive force verification device 50E of Embodiment 6 will be described.

[0095] like Figure 10 As shown, when comparing the adhesive force verification device 50E of Embodiment 6 with the adhesive force verification device 50 of Embodiment 1, the shape of the adhesive part 60E is different. Other components are largely the same.

[0096] In the adhesive part 60E, the working surfaces 61 and 62 each include a stepped portion that tends to be lower as it moves from the side closer to the reference surface 63 to the side farther from the reference surface 63.

[0097] Even in the case configured as described above, the adhesive force verification device 50E of Embodiment 6 can achieve approximately the same effect as Embodiment 1.

[0098] (Implementation Method 7)

[0099] Figure 11 This is a front view showing the state in which the adhesion strength verification device of Embodiment 7 is equipped with an electrotherapy device. (See reference...) Figure 11 The adhesive force verification device 50F of Embodiment 7 will be described.

[0100] like Figure 11 As shown, when comparing the adhesion force verification device 50F of Embodiment 7 with the adhesion force verification device 50 of Embodiment 1, the difference lies in the fact that a portion of the electrotherapy device 1 is configured to be fixed. Other components are largely the same.

[0101] In the adhesion force verification device 50F of Embodiment 7, a locking portion 65 is provided. The locking portion 65 is provided, for example, on a reference surface 63. The locking portion 65 is configured to engage with the main body portion 10. The locking portion 65 is, for example, a protrusion protruding from the reference surface 63. This protrusion is configured to be inserted into a locking recess provided on the main body portion 10. The locking portion 65 engages with the main body portion 10, thereby positioning the main body portion 10. As a result, movement of the electrotherapy device 1 can be suppressed during the verification of the adhesion force of the electrodes 20 and 30.

[0102] (Implementation Method 8)

[0103] Figure 12This is a perspective view showing the state in which the adhesive force verification device of Embodiment 8 is equipped with an electrotherapy device. (See reference...) Figure 12 The adhesive force verification device 50F of Embodiment 8 will be described.

[0104] like Figure 12 As shown, the adhesion force verification device 50F of Embodiment 8 differs from the adhesion force verification device 50D of Embodiment 5 in that it is equipped with a fixing member 56. Furthermore, as the electrotherapy device 1A, an electrotherapy device comprising a main body 10, two electrode pads 25, and two electrode wires 27 can also be used.

[0105] The main body 10 is located separately from the two electrode pads 25, which are connected to the main body 10 via electrode wires 27. Each electrode wire 27 has a connector portion 26 and can be detachably mounted to the electrode pad 25. One electrode pad 25 has the aforementioned electrode 20 and a first holding portion 41, while the other electrode pad 25 has the aforementioned electrode 30 and a second holding portion 42. The first holding portion 41 and the second holding portion 42 are formed independently, and the two electrode pads 25 are configured to move independently of each other.

[0106] In such a situation, such as Figure 12 As shown, only one electrode pad 25 can be attached to the adhesion verification device 50F. In this case, the electrode pad 25 is attached across the working surface 61 or 62 from the reference surface 63. At this time, a part of the electrotherapy device 1A (specifically a part of the electrode pad 25) can be fixed to the fixing member 56. The fixing member 56 is provided on the reference surface 63. As the fixing member 56, a rope-like member such as a rubber band or a cord can be used. In this case, the end of the electrode pad 25 is pressed against the reference surface 63 by the rope-like member. It should be noted that the fixing member 56 can also be replaced by tape or the like. Alternatively, the fixing member 56 can be omitted, and the user can press the end of the electrode pad 25 against the reference surface 63 to fix the electrode pad 25.

[0107] It should be noted that, in Figure 12 The example shown illustrates the case where the electrode pad 25 is attached to the adhesion verification device 50F while connected to the electrode wire 27, but the electrode pad 25 can also be attached only when the electrode wire 27 is removed.

[0108] (Other variations)

[0109] The adhesion force verification device may also have a first side and a second side that are opposite to each other, and is configured such that, with the holding part 40 bent into a generally U-shape, an electrode 20 is attached to the first side and an electrode 30 is attached to the second side.

[0110] The above example illustrates adjusting the peeling force by giving the action surfaces 61 and 62 a height difference, but it is not limited to this. The peeling force can also be adjusted by performing surface treatment on the action surfaces 61 and 62. For example, the surface roughness of the action surfaces 61 and 62 on the side farther from the reference surface 63 can be less than the surface roughness of the action surfaces 61 and 62 on the side closer to the reference surface 63.
