[Technical field]

[0001] The present invention relates to an electrostimulation sheet and an electrostimulation device equipped with the sheet. [Background technology]

[0002] For example, a facial beauty device that applies physical stimulation to the user's face to train the cheeks is known (see Patent Document 1). This facial beauty electrical stimulation device generates electrical stimulation called EMS (Electrical Muscle Stimulation) and applies low-frequency signals directly to the facial muscles, contracting and relaxing the muscles to exercise them.

[0003] By using this facial beauty device, the user can improve sagging cheeks, chin, etc. The device is characterized by the need to directly contact the skin of the user's face, particularly the cheeks and chin, and act on the subcutaneous muscles at the contact surface. According to the device disclosed in Patent Document 1, etc., the device is provided with a member called a pad portion or the like for contacting the user's skin. Furthermore, a viscous sheet that adheres to the skin is connected to the pad portion. The sheet is a consumable item that is replaced due to deterioration of viscosity.

[0004] By placing a viscous sheet between the pad of the electrical stimulation device and the user's skin, the sheet sticks to the skin side, and the electrical stimulation generated by the electrodes arranged in a surface pattern within the sheet is efficiently transmitted to the muscles under the skin.

[0005] [Patent Document 1] Patent Publication No. 2022-98235 Summary of the Invention [Problem to be solved by the invention]

[0006] Existing sheets for electrical stimulation devices have sufficient flexibility to be easily applied to the part of the body to be worn, such as the face of the user. However, the pads of the electrical stimulation device are made of a rigid material and cannot accommodate the complex shapes of the user's face, etc. Therefore, although the electrodes for electrical stimulation are arranged on the sheet in a planar manner, it has been considered problematic that only a portion of them contributes to electrical stimulation.

[0007] The present invention has been developed in consideration of the above problems, and provides an electrostimulation sheet that is connected to an electrostimulation device and directly contacts the user's skin, which improves the ability to conform to the shape of the user's treatment area, making it easier for the entire electrostimulation sheet to come into contact with the user's skin, thereby improving the stimulating effect of the electrostimulation device, and an electrostimulation device equipped with said electrostimulation sheet. [Means for solving the problem]

[0008] In other words, the electrical stimulation sheet of the embodiment is characterized by comprising a terminal portion which receives a supply of electric power, an electrode portion connected to the terminal portion and which generates an electrical stimulation to the user's skin, an adhesion portion which comes into contact with the user's skin, a main body portion provided between the electrode portion and the adhesion portion, with the electrode portion positioned on either the first surface side or the second surface side and the adhesion portion positioned on the second surface side, and a shape retention portion positioned on either the first surface side or the second surface side of the main body portion.

[0009] Furthermore, the shape-retaining portion of the electrostimulation sheet may be made of a metal member or a resin member.

[0010] Furthermore, the shape-retaining portion of the electrostimulation sheet may be a plate-like or rod-like body.

[0011] Furthermore, the shape-retaining portion of the electrostimulation sheet may be single or multiple, and may be disposed on the first surface side or the second surface side of the main body portion.

[0012] Furthermore, the shape-retaining portion of the electrostimulation sheet may be disposed on both the first surface side and the second surface side of the main body portion.

[0013] Furthermore, a swelling member may be provided on the application portion of the electrostimulation sheet.

[0014] The electrostimulation device of the embodiment is characterized in that it is equipped with the electrostimulation sheet described above. Furthermore, the electrostimulation device may be provided with an electrode portion connected to the terminal portion of the electrostimulation sheet described above, a power supply portion that supplies power to the terminal portion of the electrostimulation sheet through the electrode portion, and a control board that controls the power supplied from the power supply portion to the terminal portion of the electrostimulation sheet. Effect of the Invention

[0018] The electrostimulation sheet of the embodiment is connected to the electrodes of the electrostimulation device, and the electrodes provided inside the electrostimulation sheet vibrate due to the current and voltage pulse waves transmitted from the electrostimulation device. The vibration generated in the electrodes of the electrostimulation sheet stimulates the skin and subcutaneous muscles covered by the electrostimulation sheet. This promotes muscle movement and metabolism, and is effective in eliminating wrinkles, sagging, swelling, and the like, and reducing subcutaneous fat. The electrostimulation sheet may be a dedicated product corresponding to the electrostimulation device, or may be a general-purpose product that can be connected to multiple electrostimulation devices.

[0019] FIG. 1(A) is a perspective view of the back side of an electrical stimulation sheet 1A of the first embodiment. The electrical stimulation sheet 1 is a sheet-like member for electrodes that is attached to a facial beauty device (electrical stimulation device) 100 disclosed in FIG. 6 and the like, and is replaced according to a predetermined frequency of use and degree of deterioration. The electrical stimulation sheet 1A has a rectangular electrode base portion 10, and electrode terminal portions 11 are provided on the surface of the electrode base portion 10. In the embodiment, a known joining structure such as a snap button or a magnetic hook is used for convenience of attachment and detachment. A protective sheet 2 is attached to the opposite side of the electrode base portion 10 shown in the figure. The protective sheet 2 is an appropriate resin film for protecting the adhesive component of the attachment portion 30 (see FIG. 1(B)).

[0020] Fig. 1(B) is a longitudinal cross-sectional view of an electrical stimulation sheet 1A of the first embodiment. From the lower side of the page, the electrode base portion 10, the main body portion 20, and the covering portion 30 are laminated in this order and joined together with an adhesive or the like. A terminal portion 11 is provided below the electrode base portion 10 for connection to a facial beauty device (electrical stimulation device) 100 (see Fig. 6) that generates a predetermined electrical stimulation. In the figure, an electrode portion 12 is provided between the layer of the electrode base portion 10 and the main body portion 20. The electrode portion 12 is connected to the terminal portion 11 and generates an electrical stimulation to the user's skin. The covering portion 30, which is the layer above the main body portion 20, is in direct contact with the user's skin. In this embodiment, the covering portion 30 is further provided with a swelling member 35.

[0021] The surface of the main body 20 that contacts the electrode base 10 is the first surface 21 of the main body 20, and the surface of the main body 20 that contacts the attachment portion 30 is the second surface 22 of the main body 20. In the electrically stimulating sheet 1A, the electrode 12 is disposed on the first surface 21 side of the main body 20. That is, the electrode 12 is disposed so as to be sandwiched between the electrode base 10 and the main body 20.

[0022] In the electrical stimulation sheet 1A, a shape-retaining portion 40 is disposed on the second surface 22 side of the main body 20. The shape-retaining portion 40 is formed from a metal member or a resin member, for example, a metallic sheet metal, a wire, or a resin sheet formed from a resin having shape-retaining properties. The shape-retaining portion 40 is inserted into the interior of the electrical stimulation sheet 1A, and serves to retain the electrical stimulation sheet 1A in accordance with a predetermined shape of the treatment site of the user. The number and arrangement of the shape-retaining portions 40 are appropriate according to the size and shape of the electrical stimulation sheet. In the electrical stimulation sheet 1A of FIG. 1, the shape-retaining portion 40 is a single metal plate, which is a plate-like body.

[0023] Each of the electrode base portion 10, main body portion 20, and attachment portion 30 of the electrical stimulation sheet 1A is made of a flexible material such as resin or fabric. Therefore, it comes into soft contact with the user's skin. However, since it is prone to bending (flexing), it may not have the ability to follow the shape of the face or the like and always keep in close contact. Therefore, by providing the shape retention portion 40, an appropriate rigidity is added to the electrical stimulation sheet 1A itself, and the amount of adhesion is increased according to the shape of the treatment site such as the user's face.

[0024] The swelling member 35 provided in the attachment portion 30 is coated with a water-swellable resin, such as gelatin, hyaluronic acid, mannan, agar, polyvinyl alcohol, acrylic resin, etc. Since the swelling member 35 is a water-swellable resin, it becomes viscous and easily adheres to the skin of the user. When the electrical stimulation sheet is not in use, a protective sheet 2 is attached to the swelling member 35 to prevent the swelling member 35 from drying and from being attached to other items.

[0025] 2 and 3 are schematic cross-sectional views showing other embodiments of the electrical stimulation sheet. Fig. 2(A) is a schematic cross-sectional view of an electrical stimulation sheet 1B of a second embodiment. In the electrical stimulation sheet 1B, the electrode section 12 is disposed on the second surface 22 side of the main body section 20. The electrode section 12 is sandwiched between the main body section 20 and the attachment section 30. The shape-retaining section 40 is disposed on the first surface 21 side of the main body section 20, and the shape-retaining section 40 is sandwiched between the electrode base section 10 and the main body section 20. In the electrical stimulation sheet 1B, the electrode section 12 is disposed closer to the attachment section 30 than in the above-mentioned electrical stimulation sheet 1A, so that the intensity of the electrical stimulation is higher.

[0026] 2(B) is a cross-sectional schematic diagram of an electrical stimulation sheet 1C of a third embodiment. In the electrical stimulation sheet 1C, the electrode section 12 is disposed on the first surface 21 side of the main body section 20. Thus, the electrode section 12 is sandwiched between the electrode base section 10 and the main body section 20. Moreover, the shape-retaining section 40 is disposed on the first surface 21 side of the main body section 20, and the shape-retaining section 40 is sandwiched between the electrode base section 10 and the main body section 20. The shape-retaining sections 40 of the electrical stimulation sheet 1C are two wire-like metal members (rod-shaped bodies), and can retain the shape of the electrical stimulation sheet 1C from two directions, improving the shape-retaining performance.

[0027] FIG. 3(A) is a schematic cross-sectional view of an electrical stimulation sheet 1D of a fourth embodiment. In the electrical stimulation sheet 1D, the electrode portion 12 is disposed on the second surface 22 side of the main body portion 20. Thus, the electrode portion 12 is sandwiched between the main body portion 20 and the covering portion 30. The shape-retaining portion 40 is disposed on the second surface 22 side of the main body portion 20, and the shape-retaining portion 40 is sandwiched between the main body portion 20 and the covering portion 30. In the electrical stimulation sheet 1D, the electrode portion 12 is closer to the covering portion 30 than in the above-mentioned electrical stimulation sheet 1A, so that the intensity of the electrical stimulation is higher. In addition, the shape-retaining portion 40 of the electrical stimulation sheet 1D is two metal plate members, and the shape of the electrical stimulation sheet 1D can be maintained from two directions, and the shape-retaining performance is improved. The electrical stimulation sheet 1D is assumed to be an exchange sheet for a relatively large area of ​​electrical stimulation treatment site such as the thigh.

[0028] FIG. 3(B) is a schematic cross-sectional view of the electrical stimulation sheet 1E of the fifth embodiment. In the electrical stimulation sheet 1E, the electrode portion 12 is disposed on the first surface 21 side of the main body portion 20. Therefore, the electrode portion 12 is sandwiched between the electrode base portion 10 and the main body portion 20. In addition, the shape-retaining portion 40 is disposed on both the first surface 21 side of the main body portion 20 and the second surface 22 side of the main body portion 20. That is, the shape-retaining portion 40 is sandwiched between the electrode base portion 10 and the main body portion 20, and the shape-retaining portion 40 is sandwiched between the main body portion 20 and the attachment portion 30. The shape-retaining portion 40 of the electrical stimulation sheet 1E is three sheet metal-like metal members (plate-shaped bodies), and can retain the shape from two directions of the electrical stimulation sheet 1E and from the center, thereby improving the shape-retaining performance. The electrical stimulation sheet 1E is assumed to be an exchange sheet for a relatively large area of ​​electrical stimulation treatment site with a large amount of unevenness, such as the buttocks.

[0029] The electrical stimulation sheets 1A to 1E disclosed in Figures 1, 2, and 3 are representative examples of the arrangement of electrode portions 12 and shape-retaining portions 40. Of course, arrangements other than those shown in the figures are permitted and the sheet is not limited to the structures shown in the figures.

[0030] 4 and 5 show examples of the shapes of the shape-retaining parts 41 to 46 (shape-retaining part 40). Note that, since the main purpose of each drawing is to explain the shape of the shape-retaining part 40, the arrangement on the first surface 21 side or the second surface 22 side of the main body part 20, or the arrangement on both sides, is omitted.

[0031] 4(A) is a schematic plan view showing the shape retaining part 41 of the first embodiment, which is a single plate-like or rod-like body made of a metal or resin member. The shape retaining part 41 is disposed in the center of the main body part 20 along the longitudinal direction of the main body part 20. Since there is only one shape retaining part 41, the manufacturing cost is low.

[0032] The schematic plan view of Fig. 4(B) shows shape retaining parts 42 of the second embodiment as two plate-like or rod-like bodies made of metal or resin members. Shape retaining parts 42 are arranged in a position approaching the center from the long side of main body part 20 along the longitudinal direction of main body part 20. Since there are two shape retaining parts 42, they are only effective for abutment when the shapes of the objects to be attached are different on the left and right sides of main body part 20.

[0033] The schematic plan view of Fig. 4(C) shows shape-retaining portion 43 of the third embodiment as a Y-shaped metal or resin plate or rod in plan view. Shape-retaining portion 43 is disposed in the center of main body 20 along the longitudinal direction of main body 20. For example, even if the shape of the treatment site for electrical stimulation to which the electrical stimulation sheet is applied differs at both ends in the longitudinal direction of the electrical stimulation sheet, the electrical stimulation sheet can be made to flexibly follow and accommodate the treatment site by improving its adhesion to the treatment site.

[0034] In the schematic plan view of Fig. 5(A), the shape-retaining portion 44 of the fourth embodiment is a plate-like or rod-like body made of a metal or resin material that is V-shaped in plan view. The shape-retaining portion 44 is disposed in the center of the main body portion 20 along the longitudinal direction of the main body portion 20. Compared to the shape-retaining portion 43 of the third embodiment in the schematic plan view of Fig. 4(C) described above, the shape-retaining portion 44 of the fourth embodiment is V-shaped, so that it has a suitable width and improves the ability of the electrical stimulation sheet to conform to the shape of the treatment site in the short direction.

[0035] The schematic plan view of Fig. 5(B) shows the shape-retaining portion 45 of the fifth embodiment as a plate-like or rod-like body made of a metal or resin material having a W-shape (M-shape) in plan view. The shape-retaining portion 45 is disposed in the center of the main body portion 20 along the longitudinal direction of the main body portion 20. The shape-retaining portion 45 of the fifth embodiment is W-shaped rather than V-shaped compared to the shape-retaining portion 44 of the fourth embodiment in the schematic plan view of Fig. 5(A) described above, so that the shape-retaining portion 45 covers a larger amount of the main body portion 20, and the ability of the electrical stimulation sheet to conform to the shape of the treatment site in both the longitudinal and lateral directions is further improved.

[0036] The schematic plan view of Fig. 5(C) shows the shape-retaining portion 46 of the sixth embodiment as a plate-like or rod-like body of a frame-shaped metal member or resin member in a plan view. The shape-retaining portion 46 is disposed inside the periphery of the sides of the main body portion 20. The shape-retaining portion 46 of the sixth embodiment enhances the shape-retaining performance of both the corners and sides of the rectangular electrical stimulation sheet. Therefore, the corners and periphery of the sides of the electrical stimulation sheet further improve the ability to follow the shape of the object to which it is attached.

[0037] The shape-retaining portion 43 of the third embodiment to the shape-retaining portion 46 of the sixth embodiment are processed by punching a metal plate or a resin plate with, for example, a Thomson blade. Alternatively, punching processing by laser irradiation, water jetting, etc. is adopted. The type of shape-retaining portion to be adopted is selected according to the size and shape of the electrostimulation sheet. In addition, it is possible to use them according to the part of the user where the electrostimulation sheet is used.

[0038] The shape-retaining portions 40 (41 to 46) disclosed in Fig. 4 and Fig. 5 may be arranged on any of the electrostimulation sheets 1A to 1E of the embodiments in Fig. 1 to Fig. 3, and in one electrostimulation sheet, shape-retaining portions 40 of different shapes may be arranged on both sides of the main body portion 20. The size, shape, manufacturing cost, etc. of the electrostimulation sheet are taken into consideration.

[0039] Figures 6 to 8 show an example of an electrostimulation device, and the figures show a headphone-type facial beauty device 100 as the electrostimulation device. Figure 6 is an overall perspective view of facial beauty device 100 as the electrostimulation device, and Figure 7 is an overall front view of facial beauty device 100. Figure 8 is a schematic diagram showing how facial beauty device 100 is used. In the following explanation, the front-rear direction, left-right direction, and up-down direction are defined based on the orientation of the user using facial beauty device 100.

[0040] The facial beauty device 100 has a structure in which the left and right pad sections 110 that apply electrical stimulation are connected by a connecting section 111, and includes a headband 112 that covers the user's head, a pair of slider bands 113 that extend from both ends of the headband 112, and a pair of housings 114 that are connected to the slider bands 113. The headband 112 also serves as the connecting section 111. Note that instead of the headband 112 that covers the user's head, a neckband (not shown) that covers the back side of the user's neck (cervical region) may be used. The pad section 110 is provided with a pad electrode section 120. The pad electrode section 120 is structured to be joined to the terminal section 11 of the aforementioned electrical stimulation sheet 1A, etc., and for example, a snap button structure that joins by mutual unevenness is adopted. Therefore, the electrical stimulation sheet 1A, etc. is attached to the pad section 110 (see FIG. 9) and is used by the user. In addition, the pad section 110 itself may be configured to directly include the electrical stimulation sheet 1A, etc.

[0041] The illustrated facial beauty device 100 is provided with a power switch 130 at one end of the connecting part 111 (headband 112). A battery (not shown) is built into the power switch 130 as a power source. The power switch and other stimulation intensity adjustment switches (not shown) may be provided in positions on the pad part 110 that are easy to operate.

[0042] 7, the thickness dimension in the left-right direction of slider band 13 is smaller than the thickness dimension of headband 112 and is uniform over the entire area of ​​slider band 113. Slider band 113 is arranged so as to be housed inside headband 112, and the length can be adjusted by pulling out from headband 112 according to the position of pad portion 110 selected by the user. Since the length of slider band 113 is adjustable, pad portion 110 comes into contact with a position desired by the user.

[0043] Furthermore, the housing 114 is connected to the lower end of the slider band 113. The housing 114 accommodates the lower end of the slider band 113 and holds the pad portion 110. As shown in Figures 6 and 7, the pad portion 110 is connected to the housing 114 via a support shaft 115. The support shaft 115 supports the pad portion 110 rotatably with respect to the housing 114, which is both ends of the connecting portion 111, and is provided inside the housing 114.

[0044] The pad electrode section 120 is a stimulation section for applying electrical stimulation to the skin of the user to the electrical stimulation sheet 1A or the like. The operation of the pad electrode section 120 is executed based on a predetermined stimulation condition. The stimulation condition is a state in which the current and voltage fluctuate under the control of a control circuit (not shown) of a control board 160 built into the facial beauty device 100 (electrical stimulation device). A plurality of types of stimulation conditions (current and voltage states) are prepared in advance according to the level of stimulation (strength and weakness), and are stored in a memory element (memory) of the control board 160. Furthermore, the facial beauty device 100 (electrical stimulation device) is equipped with a wireless communication circuit (not shown), and a control signal may be sent to the facial beauty device 100 from a terminal device such as a smartphone afterwards to add a new stimulation condition.

[0045] FIG. 8 is a diagram showing an example of how the facial beauty device 100 is used. As shown in FIG. 6, the slider band 113 is stretched, and the pad section 110 rotates on the support shaft 115. The pad section 110 contacts a portion of the face Uf of the user U that is located on the inside of the face in the left-right direction from the center of the eye. At this time, the pad section 110 can be used to cover not only the orbicularis oculi muscle, the zygomatic major muscle, and the buccinator muscle, but also at least a part of the orbicularis oris muscle and the levator labii superioris muscle. Through the stretching and contraction of the slider band 113 and the rotation on the support shaft 115, the left and right pad sections 110 can abut against each part of the face Uf. As a result, the muscles of the face Uf of the user U can be tightened (pumped up), and the sagging of the cheeks can be eliminated, and a small face effect can be expected.

[0046] As is clear from the description of the usage mode of the facial beauty device 100 in Fig. 8, the pad section 110 reaches each part of the face Uf of the user U, such as under the eyes, cheeks, and chin, and electrical stimulation is given to the subcutaneous muscles through the electrical stimulation sheet 1A, etc. However, as shown in the structure of the pad section 110 of the facial beauty device 100 disclosed in Figs. 6 and 7, the pad section 110 is formed of a rigid material such as a rectangular parallelepiped resin, so that with the conventional electrical stimulation sheet, it is not easy to follow the three-dimensional structure of the user's face, and the electrical stimulation sheet could only partially abut against the face. Therefore, the area causing electrical stimulation is reduced compared to the area of ​​the electrical stimulation sheet, and the effect of electrical stimulation is reduced.

[0047] In contrast, when the electrostimulation sheet 1A of the embodiment shown in Fig. 9 is attached to a facial beauty device 100 (electrostimulation device), the electrostimulation sheet 1A itself is given appropriate rigidity by being provided with a shape-retaining portion 40. Therefore, by bending the shape-retaining portion 40 in advance to match the shape of the face Uf of the user U, almost the entire electrostimulation sheet 1A will be attached to the curved surface, such as the lower jaw of the face Uf of the user U, following the shape of the site on the face Uf of the user U where electrical stimulation is to be performed, and the amount of adhesion of the electrostimulation sheet 1A to the skin will increase.

[0048] As a result, electrical stimulation is efficiently transmitted to the user's skin from the electrode section 12 built into the electrical stimulation sheet 1A, further enhancing the effect of the electrical stimulation set in the facial beauty device 100 (electrical stimulation device). Furthermore, in conventional facial beauty devices (electrical stimulation devices), it is necessary to intentionally increase the intensity of the electrical stimulation, taking into account that the electrical stimulation sheet only adheres partially to the skin. However, since almost the entire electrical stimulation sheet can adhere to the skin, the same effect can be expected even if the intensity of the electrical stimulation is weakened. This makes it possible to reduce battery consumption in the electrical stimulation device and the load on the device itself.

[0049] In FIG. 9 and the like, the electrostimulation sheet 1A is used. Alternatively, any of the electrostimulation sheets 1B to 1E in FIG. 2 and FIG. 3 may be used. The shape of the shape retaining portion 40 may also be any of the shape retaining portions 41 to 46 in FIG. 4 and FIG. 5. Furthermore, the application site of the electrostimulation sheet may be attached to other electrostimulation devices in addition to the facial beauty device 100 shown and described. For example, it may be applied to an electrostimulation device that applies electrical stimulation to the abdomen, thighs, buttocks, etc. In particular, since the electrostimulation sheet has the shape retaining portion 40 (41 to 46) shown in the figure, the ability to follow the curved surface of the treatment site is improved, and the entire surface of the electrostimulation sheet is attached to the treatment site, enhancing the effect of the electrical stimulation.
